These instructions will take you through the basic extract
brewing process for all Brewer's Apprentice extract homebrew
kits. Please review the specific recipe and instructions
given to you with your homebrew kit; while the following
instructions hold true for almost all extract homebrew recipes,
some recipes go beyond the normal instructions and/or add
or remove certain steps. If there are any additional steps
for your specific recipe, it will be noted on your recipe
printout. If, after reading the instructions below, you
have any remaining questions regarding your specific recipe,
feel free to give us a call at the store! There's a lot of
instructions on this page, so we've done our best to format
this webpage for easy printing; It makes life a lot easier
to have the instructions with you while you're in the kitchen!
Step 1) "Mise En Place"
The first step in homebrewing, and one of the most
critical steps, is preparation. A French phrase used by
chefs and culinary schools around the world, "Mise
En Place" literally means to "get everything into place"...
and it's a great thing for the homebrewer to remember. Making
sure that all of your ingredients are in place and that
all of your equipment is sanitized and ready to be used
before you brew makes homebrewing a whole lot more
fun because it makes things go more smoothly and reduces
the chances of something going wrong. Make sure that you've
completed the following tasks before you brew:
a) Double check your recipe kit. Make sure
that you have all of the ingredients that are listed on
your recipe printout. If you think something is missing,
call us before you brew!
b) Make sure that you have the proper equipment.
At the minimum, this includes:
- A brewing pot (at least 16 quarts or larger)
- A candy or brewing thermometer (preferably with clip)
- A large, heat-resistant paddle or spoon
- A fermenter (either a 6.5 gallon bucket or 6 gallon
carboy)
- An airlock
- If using a carboy - a funnel (for pouring wort into
carboy)
- A cleanser/sanitizer (such as One-Step or B-Brite)
- Plenty of ice or a chiller (to cool the wort down
before the yeast is pitched)
- 5 gallons of filtered tap water or distilled water
(we do not recommend spring water!)
c)
Review what type of yeast you will be using. If your recipe
uses dry yeast, simply have it on the counter next to
your other brewing ingredients and we will touch on what
to do with it later. If you are using liquid yeast, first
remember that liquid yeast should be stored in the refrigerator
up until the very moment you are about to use it. If you
are making a standard beer with a vial of White Labs yeast,
simply remove the liquid yeast from the refrigerator and
place it in your pocket to help warm it up; as you brew
make sure to shake the vial now and then to help ensure
that the yeast is well mixed. If you are making a standard
beer with a SmackPack of Wyeast, remove the yeast from
the refrigerator, at the least, a few hours before you
begin to brew and smack the pack according to the directions
on the packaging; DO NOT pitch the Wyeast unless the SmackPack
fully expands. If you are brewing a higher gravity beer
(such as barleywine, Belgian trippel, imperial stout,
etc.) with either White Labs or Wyeast, we highly
recommended that you prepare a yeast "starter"
24 to 48 hours before you brew. For instructions
on making a yeast starter, scroll to the very bottom of
these instructions or click here.
Step 2) Preparing The Water
& Steeping The Grains
a) First, review the size of your brew
pot. If it is on the small side (16 - 20 quarts {4 - 5
gallons}), collect and heat 2 - 2.5 gallons of water.
If you have a full-sized (30 quart {7.5 gallon} or larger)
pot, collect and heat 5 gallons of water. Heat your water
to 170°.
*If your recipe doesn't include grains,
skip step "2b" below and proceed to step 3*
b) Once your water has reached 170°, remove
the thermometer and turn off the heat. Place your crushed
grains into the long cheese cloth sock (a.k.a. grain sock)
and tie it off. Place the sock into the pot of water,
making sure to let the knotted end hang outside of the
pot. Close the lid and let the grains steep for 30 minutes.
Occasionally lift the pot lid and bob the grains up and
down in the water, returning it to its normal steeping
position when done.
Step 3) Preparing For The Boil
a) Before you get ready to boil your beer,
you'll want to make sure and double check that you've
prepared all of your ingredients and equipment. If you're
using liquid malt extract, make sure it's not too cold,
as this will make it hard to pour... If it is too cold,
simply fill your sink with some hot tap water and let
the malt containers bathe for a few minutes or so... this
will help to warm it up and make it easier to pour. If
you're using dry malt extract, make sure to have a good
pair of scissors at the ready. Also make sure to sanitize
any equipment that will be touching the wort after
it has cooled. For tips on sanitizing your brewing
equipment, scroll to the very bottom of these instructions or click here.
b) Once you're sure that all of your ingredients
and equipment are ready to go, you can then prepare to
boil your wort ("wort" is what beer is called
before the yeast is added). If you were steeping grains,
lift the grain sock after 30 minutes and carefully (and
gently) squeeze any remaining liquid from the sock...
there's lots of flavorful wort in there! Next, discard
the grain sock. Turn on the heat to your pot. You'll want
to use the highest heat setting that you have. Put your
thermometer back into the pot if you removed it. You will
now wait and do nothing until the liquid in your pot reaches
about 200°. As your kettle approaches 200°, it's time
to have your malt extract(s) and your spoon or paddle
in place... it's time to boil!
Step 4) Boiling The Wort
a) Once your pot reaches 200°, it's time
to start adding your malt extracts. If you're using liquid
malt extract, make sure to get every last drop of extract
out of the containers (a spatula makes this job a lot
easier). If you're using dry malt extract, cut the bag(s)
open and carefully (but quickly) pour the dry malt extract
into the pot... be careful... if you pour too slowly,
dry malt extract tends to coagulate... it's not the end
of the world if this happens, but it can be a bit messy!
If your recipe uses any other brewing sugars (such as
Belgian candi, brown sugar, honey, etc.), put those into
the pot as well. DO NOT add the bag of priming sugar.
Priming sugar is added at bottling time, not during the
brew!
b) Once you've gotten all of the malt extract
(and any other sugars) into the pot, it's time to stir.
Make sure to stir well, making sure that there's no malt
sugars on the bottom of the pot. Within a minute the malt
extract should be totally dissolved into the liquid. If
you leave any clumps of sugar on the bottom of the pot,
they may burn and create off flavors, so stir thoroughly!
c) Now you're getting into the thick of
things! From here on out, you have to be careful and watch
your pot at all times. Despite the old saying, a watched
pot does boil! If a brew pot is left unattended
it can easily boil over, leaving a terrible mess behind.
The moment your wort starts to boil, temporarily shut
off the heat (from here on out, whenever you are about
to add another ingredient to your pot, we highly recommend
temporarily turning off the heat to your pot, as this
will help avoid suddend flair ups and boil overs).
d) Once your pot hits a boil, and after
you've temporarily turned off the heat, it's time to add
your first hops (a.k.a. bittering or flavoring hops).
Unless your recipe says otherwise, bittering hops are
always added at the beginning of your boil. When
you add the hops you will notice that they usually react
quite violently. Wait for the hop reaction to subside,
there is no need for stirring. Once the hops have settled
down, you can turn the heat back on to full. Unless your
recipe says otherwise, you will boil your homebrew for
60 minutes. Don't forget, for the next 60 minutes someone
should always be watching the pot.
e) A Note On Hop Additions... While there
are some recipes that stray from the rule, most homebrew
recipes follow a pretty strict hop addition schedule.
Specifically, most recipes have 2 hop additions: the bittering
(a.k.a. flavoring) hops and the finishing (a.k.a. aroma)
hops. Here are some general rules:
- Bittering hops are almost always added at the very begining of the
boil and boil in the wort for 60 minutes.
- Finishing hops are almost always added when there
are 15 minutes left in the boil.
- If a recipe uses spices, they are most often added
with the finishing hops.
- If your recipe has "dry hops", place
them in the smaller cheese cloth sock (a.k.a a hop sock)
that was provided with your recipe and tie the sock off.
When you are seconds away from the end of your 60 minute
boil, grab the hop sock with a pair of tongs and fully
submerge it in the boiling wort
for a couple of seconds... this will help to sanitize
it. Immediately put the sanitized
hop sock into your fermenter... you will later
pour your cooled wort onto the hop sock and it will steep
in your beer whilst it ferments.
If your recipe goes beyond
a normal recipe it will have specific instructions, telling
you when to add a specific ingredient.
f) Continue on, boiling your wort, adding
hops or other ingredients as indicated in your recipe.
When you have completed the boiling process for your recipe
it will be time to cool your wort. When you are done boiling,
turn off the heat and put the lid on the pot.
Step 5) Cooling The Wort
a) Now that you have brewed your wort,
you must cool it down to 60° - 80°. Most new homebrewers
will use an icebath to do this and some will use a "wort
chiller". If you are like most beginners, you will
simply use an icebath. To do this, make sure to have lots
of ice on hand. Fill your sink with plenty of ice and
just enough water so that you'll be able to easily put
the pot into the sink. Make sure that the water level
in the sink isn't too high! The water level in your sink
should go somewhere in between a 1/2 to 3/4 of the height
of the pot. Make sure to jostle the pot around every few
minutes. After 15 to 20 minutes, sanitize your brewing
thermometer and check the temperature of your wort. Once
it's between 60° - 80° your ready to put it into the fermenter.
b) When the wort is cooled to the proper
temperature, it's time to pour it into your fermenter. Again,
make sure that your fermenter is sanitized. If you're using
a bucket, remove the lid. If you're using a carboy, put
a sanitized brewing funnel in the top. Pour the wort into
the fermenter. There's no need to be delicate at this stage,
just make sure you don't spill any wort on the floor. The
rougher you pour the beer, the more it sloshes around and
foams up... this is a good thing. When you pour the wort
in this manner it's folding in lots of air and oxygen which
the yeast will use as they ferment. Please note, however,
that this is the last time you will be rough with your beer,
as introducing oxygen later on down the line after it has
fermented can oxydize the beer and spoil it.
c) Please note: you should never
pour hot wort directly into an empty fermenter, nor should
you ever pour hot wort directly into a fermenter full
of cold water. Some brewers do this thinking that they
can cool the wort, get the beer to volume, and save time...
but this is one of the worst things you can do, for a
number of reasons. We highly recommend either using an
ice bath or wort chiller to cool your wort down. If you
need to add water to get your beer to 5 gallons, make
sure the water is at room temperature.
Step 6) Taking The Gravity
a) This is a step often neglected by the
beginner and seasoned homebrewer alike. For some reason,
it seems that a lot of people think that this step is
too complicated or difficult and don't bother with it...
but nothing could be further from the truth. Taking the
gravity of your beer is extremely quick and easy and offers
way more positives than negatives.
b) Taking your beers gravity allows you
to first confirm if your beer was brewed properly. Second,
it can be used to see if your beer is fermenting or not.
Finally, by taking both the original gravity (before the
beer ferments) and final gravity (after the beer is done
fermenting), you can do some simple math and figure out
the ABV (alcohol by volume) of your beer.
c) To take your beers gravity all you need
is a "thief", a hydrometer, and a hydrometer test
stand (a.k.a. hydrometer test jar). A thief is a device
that allows you to take a sample of a fermented beverage
in a sanitary fashion. A hydrometer is a glass device shaped
like a long, narrow buoy. It has a long neck with lots of
numbers on it. A hydrometer test stand is a tall, narrow
vessel that holds your sample of beer and allows the hydrometer
to float.
The first step is to sanitize your thief. Then simply use
the thief (per the manufacturer's instructions) to take
a sample of your beer and put that sample into the hydrometer
test stand along with the hydrometer.
 |
You want to take enough of a beer sample so
that the beer fills the entire test stand. This makes
it much easier to read where the meniscus (the surface
of the beer) touches the scale on the hydrometer.
Most homebrewers use a triple scale hydrometer; the
scale that you want to use is the gravity scale, which
usually has numbers from .990 - 1.170. When the beer
sample is in the test stand, give the hydrometer a
good spin (in the same way you would spin a top),
this will help dislodge any bubbles that could give
a false reading. When it's done spinning, find where
the level of the beer meets the gravity scale, record
this number... this is your original gravity (or O.G.
for short). An average beer will have an original
gravity of around 1.045. |
d) When you think your beer is done and the
airlock no longer bubbles, carefully take another sample
of beer and take the gravity again... this will be called
your final gravity (or F.G. for short). This time the gravity
should be noticeably lower. An average final gravity will
be around 1.010. To be sure that your beer is actually done
fermenting, we strongly recommend that you take a final
gravity and then wait a couple of days and take it again...
if there is a difference in the gravity then the beer is
stil fermenting, if the gravities are the same, then your
beer is most likely done ferementing.
e) To figure out your ABV% (alcohol by volume),
simply minus the final gravity from the original gravity
and divide the sum by 7.5. For example, if your original
gravity was 1.045 and your final gravity was 1.010, then
the difference would be 35. So, divide 35 by 7.5... the
answer is 4.66, so you now know that your ABV is 4.66%! Easy!
Step 7) Pitching The Yeast
a) "Pitching" is the term brewers
use for putting yeast into beer. Regardless of what type
of yeast you are using, first make sure that your beer is
in between 60° - 80°... different yeasts prefer different
temperatures, but most want to start
somewhere in that range. So review
your yeasts packaging to see what they specifically recommend.
b) If you are using dry yeast in a packet,
you have two choices. You can either simply pitch the dry
yeast into the fermenter and give it a good shake, or, more
ideally, you can "proof" the yeast beforehand.
To proof dry yeast all you have to do is collect a cup or
so of filtered or distilled water. Place the water into
a sanitized, microwavable container and heat it just long
enough to get it in the range of 60° - 80°... this should
take less than 30 seconds. When you're sure the water is
in the ideal range, pitch the yeast into the container of
water and stir it with a sanitized spoon. Next, cover the
container over with a lid or platic wrap. Let the yeast
stand for about 10 mintues. After about 10 minutes the yeast
should have "proved" itself... it should be foamy
and smell of fresh, yeasty bread... If it does, pitch it
into your fermenter and give the fermenter a good shake to
help mix the yeast in. If the yeast does not proof, give it
up to 30 minutes to prove it self... if it still doesn't,
we recommend that you get new yeast.
c) If you are using liquid yeast, make sure
you have prepared it as described at the beginning of these
instructions. Give the yeast one last shake to make sure
that it is thoroughly mixed and fluid. If you are using
White Labs yeast in a vial, first sanitize the cap either
by spraying or dipping it in a homebrew sanitizer or alcohol.
Shake off any excess sanitizer, carfully twist off the cap
and pour the yeast into the fermenter. If you're using a
Wyeast SmackPack, spray or dip it into sanitizer or alcohol.
Shake off any excess sanitizer, cut off one of the top corners,
and carfully pour the yeast into the fermenter. Once your
White Labs or Wyeast yeast has been poured, give the fermenter
a good shake to make sure that the yeast has been thoroughly
mixed in with the beer. Now it's fermentation time!
Step 8) Fermentation
a) Within 24 to 48 hours from the time you
pitched your yeast, you beer should begin to ferment. Make
sure that you do your best to put your fermenter in the
temperature range that the yeast prefer so that they can
ferment quickly and healthfully... if you don't, this can
potentenially prevent fermentation or create off flavors.
As the yeast start to eat the sugars in the beer, they will
produce alcohol and burp out CO2... this is fermentation
in a nutshell. This phase of fermentation is called "primary
fermentation" and it usually will
last between 1 to 2 weeks.
b) As primary fermentation is winding down,
being a new homebrewer, you'll have a decision to make...
whether or not to do a secondary fermentation (more on this
below). If you decide not to do a secondary fermentation,
then you need to be absolutely sure that you beer is done
fermenting before you move on to the bottling stage. When
you notice that your airlock is no longer bubbling, take
your final gravity (as described previously). Wait two more
days and take the gravity again. If the gravity has changed,
then your beer is still fermenting and you should wait a
few more days and repeat the gravity taking process. If
the gravity doesn't change after two days, then it is most
likely done fermenting and you can move on to the bottling
stage.
c) Secondary fermentation is more about refining
your homebrew than it is about actual fermentation. It allows
your beer to settle down, letting any remnant particles
fall to the bottom; any last bits of sugar are fermented
by the yeast; and all of the flavors can start to marry
together, getting a head start before bottling time.
If
you choose to put your beer into a secondary fermentor,
we highly recommend that you use a 5 or 6 gallon carboy.
One of the reasons you are putting your beer into secondary
fermentation is for clarity, and it's very hard to tell
how clear your beer is in a bucket... in a carboy, on the
other hand, it's very easy to tell how clear your beer is.
The best time to move your beer into a secondary fermenter
is when it is just about done fermenting... 1 bubble from
the airlock per minute is a good rough guide for ales and
1 bubble per two minutes is a good rough guide for lagers.
When you are ready to move your beer to a secondary
fermenter, siphon it delicately; you don't want to introduce
any oxygen. Once the beer has been moved, replace the airlock
and put the fermenter somewhere that is cool and dark. If
you're using a carboy as suggested, it's a good idea to
wrap a bath towel or blanket around it, as this will both
prevent any light from striking the beer as well as help
to insulate it.
Once beer has been placed into a secondary,
it should be left there for a minimum of 2 weeks... if you
remove the beer before this time, it really won't have benefitted.
Some beers should be allowed to sit even longer. Keep learning
as you brew and you'll get better and better at judging
how long to age your beer.
Step 9) Bottling
a) The first step in bottling your beer is preparing your
fermenter. Whether you did just the primary fermentation or also
did the secondary fermentation, you'll need to be careful with
this step. At least an hour before you plan on bottling, ideally
the night before, you'll need to carefully lift your fermenter up
on to a counter that is at least a couple of feet off the ground. You need
to be careful not to disturb any of the trub (the gross stuff that
settles to the bottom of your fermenter), as you want this to be
left behind when you move your beer into the bottling bucket.
b) Next, make sure that you have all of the
proper equipment and materials on hand. At the minimum you'll
need:
- A bottling bucket with spigot
- A bottle filler
- Siphon equipment (we recommend using an auto-siphon and racking cane)
- Tubing for siphon equipment (4' - 6') and bottle filler (3")
- Bottles (approximately 2 cases of 12 oz. or 22 oz.)
- Crown caps (if using cap-able amber bottles*)
- A bottle capper (if using cap-able amber bottles*)
- A small sauce pot
- A spoon
- 5 oz. of priming sugar
*We strongly recommend
that you avoid using clear or green beer bottles!
c) Make sure to sanitize everything but the
capper, pot, and spoon. The easiest way to do this is to
put 6 tablespoons of One-Step or B-Brite into the bottling
bucket (make sure the spigot is closed!) along with the
bottle filler, siphon equipment, and tubing... then fill
it to the brim with warm tap water. In a small bowl, put
the crown caps with a small sprinkle of sanitizer and fill
that with warm tap water as well. In a large laundry sink,
or container, mix an appropriate amount of One-Step or B-Brite
with warm tap water and submerge all of your bottles in
the solution. Let the equipment and bottles soak for 10
to 15 minutes.
d) After 10 or 15 minutes, quickly rinse
the bottles out and put them on a bottle tree or upside
down in their original cases. Next, empty the bottling bucket
through it's spigot... this will ensure that there's no
bacteria hiding within the spigot. When the bucket is drained
of sanitizer, rinse it, and the equipment within, making
sure that there's no sanitizing chemicals left behind. Don't
forget to let some water drain through the spigot as well!
e) Delicately attach 4 to 6 feet of tubing to the cane within the sanitized
auto-siphon and attach the other end to a racking cane. Next, carefully slide the
auto-siphon into the beer that is sitting on the counter. Make sure not to jam the
bottom of the siphon into the trub at the bottom! Then place the bottling bucket
on the floor beneath the fermenter. Place the racking cane into the bottling bucket.
Gently start the auto-siphon and siphon the beer to the bottom of the bottling bucket.
Make sure that the racking cane is at the very bottom of the bottling bucket so that
no splashing occurs. It's a good idea to place a lid on top of the bottling bucket at
this point... you won't be able to put it on all the way obviously (becuase of the racking
cane), and that's okay. You're just trying to prevent any germs from falling into the
bucket as it fills.
f) As the beer is siphoning into the bottling
bucket, pour about a pint of filtered or distilled water
into the pot and bring it to a boil. When the water begins
to boil, add all of the priming sugar from the 5 oz. packet
that was provided with your recipe kit. Stir the sugar to
dissolve. Boil the sugar water for a few minutes and then
turn the heat off. When the beer is almost done siphoning
into the bottling bucket, gently and evenly pour the sugar
water into the beer (it's okay that the sugar
water is hot). Use the racking cane as a spoon, and
carefully, but thoroughly, stir the the sugar into the beer.
It's extremely important to make sure that the sugar is
evenly distributed throughout the beer so that all of the
beer bottles carbonate evenly later on!
g) Once all of the beer has been siphoned
into the bottling bucket, move the fermenter and siphon
equipment out of the way, and then carefully lift the bottling
bucket up on to the counter. Make sure you have a lid on
top of the bucket and that the spigot is facing you and
pointing down. Now, carefully attach the bottle filler to
the spigot with small piece of tubing (same
diameter tubing that you used for siphoning, just
a few inches is fine). Once the spigot is securely connected
to the bottle filler, open the spigot up... the beer will
flow to the bottom of the bottle filler.
h) It's finally time to bottle! Pour the
sanitzer out of your bowl of caps and rinse them. Make sure
that your bottles and capper are nearby. Grab a bottle and
bring it up to the bottle filler, allowing the bottle filler
to slide inside the bottle... as soon
as the bottom of the bottle filler hits the bottom of the
bottle it will begin to fill. Allow the bottle to fill all
the way to the top and then quickly remove it from the filler...
the beer should drop to about half way up the neck. Carefully
grab a crown cap, trying to avoid touching the inside of
the cap (to help prevent infections later on) and place
it on top of the bottle and cap it with the capper. Don't
push too hard with the capper! If you see a dimple in the
cap after capping, then you probably pushed to hard.
Step 10) Conditioning
a) Once your beer is bottled you will want
to store it for at least 2 weeks at the right temperature.
For ales, room temperature is ideal (around 68°) and for
lagers, the high 50's to low 60's is best. Usually the basement
suits this purpose perfectly for most households. If you don't
have a basement, a closet will work. By no means, do you
ever want to condition or store your beer in the
garage! Keeping your beer in the garage is about the same
thing as keeping your beer outside, and the yeast will suffer
from the temperature fluctuations as the day turns into
night and night into day. In short, keep your beer in a
place that consistently has a temperature that is as close
as possible to the ranges mentioned above.
b) After two weeks or so, you should test
one of your bottles for carbonation. Open it up and listen
for positive "phhfffssst!" sound that you're used
to hearing when you open any good bottle of beer. If that
sound is there, then pour some of the beer into a glass
and look at the carbonation... If it looks carbonated, taste
it. If you are happy with the level of carbonation, then
you can continue to store the beer where it is, or put it
in a fridge. If the beer isn't completely carbonated, then
the only thing you can do is wait. Sometimes homebrew will
carbonate quickly and sometimes it will take longer than
expected. A biological process is occuring in each and ever
bottle that you capped, and just like
everything else in life, you can't always predict what will
happen. Most average beers should be completely carbonated
within a month if they are stored at the right temperature.
If you bottled beer that is higher in alcohol, this can
greatly increase the time it takes to bottle condition...
some beers are known to take months to carbonate!
Step 11) Drink!
a) At least two weeks have
past and you've waited until the beer had a good carbonation
level. Now it's time to enjoy the fruits of your labor!.
Assuming you didn't make any major mistakes, you should
be enjoying a beer that is probably better than you expected...
and it will only get better!
b) Despite what a lot of larger breweries tell
you, you don't want to drink your beer as quickly as possible.
"Born On Dates" are a gimmick used by companies that
want to move lots of beer, and move it fast. But you are a
homebrewer... you've produced a beer that is better than most
commerical beers, and you're just starting out. Even the lightest
of homebrews will get better with age. Pilsners and lagers will
develop better and better flavor for 3 to 6 months after bottling.
Then they will plateau for another 3 to 6 months... giving you up
to a year to enjoy your homebrew. If you brew bigger beers, they
can develop even more flavor and age even longer. As a general
rule, the more alcohol and/or hops a beer has, the longer it can
age. Barleywines, some IPAs and stouts, etc., don't even hit their full
potential until they've aged 6 months to a year!
Cheers!
Making A Yeast Starter
If you're making a higher gravity beer and you're using
liquid yeast, it's imperative
that you have as many yeast cells as possible. If a beer
is going to have a gravity over 1.060, we highly recommend
that you make a yeast starter. Some brewers make it a standard
practice, making a yeast starter regardless of the gravity of the beer they're
about to brew... and these brewer's rarely have a bad beer. If
you're using dry yeast, there's is less of a need to make a starter,
but you should, at the least proof it, as described earlier.
There are a quite a few reasons to make a yeast
starter and the benefits will most likely improve any beer
that is fermented with one. Let's look at the reasons for
making a starter:
- Increase the yeast cell count. Starting yeast properly can double,
even triple, the yeast cell count. This greatly reduces the chances of infection
and greatly increases the ability of the yeast to ferment higher gravity beers.
- Improve yeast vigor. Making a starter improves the health of a yeast colony
and makes it more viable. Healthy yeast cells ferment faster, produce less
undesirable byproducts, are more likely to attenuate or ferment to their full
potential, and have an improved resistance to alcohol.
- Shorten the lag time. A yeast starter provides more healthy yeast that are
actively reproducing (and fermenting) which can drastically cut down on the lag time
between when you pitch the yeast and the time that it actually strarts to ferment
the beer. This allows your beer to be fermented more healthfully and greatly reduces
the chance for infection.
- Reduces the stress on the yeast. If yeast is under-pitched, the
cells can become stressed, which can lead to chemicals that lead to off flavors, poor
reproduction (and therefore poor fermentation), as well as poor resistance to other organisms
and alcohol... making it less able to fend off infections and less able to ferment in the pressence of
higher alcohol levels.
Yeast starters can be made in a variety of ways. Generally you should shoot for a
volume of about 1 quart per 5 gallons of homebrew. If you are using liquid yeast,
you will need to prep it before you make a starter. For White Labs, you will simply
want to remove the yeast from the refrigerator, keep it in your pocket for approximately
a half hour and occasionally shake it well to make sure that it is mixed. For Wyeast,
we recommend smacking the SmackPack the night before making the starter. If you are using dry
yeast for your starter, no preparation is needed. When your yeast is ready, follow these
steps:
- Prepare your equipment. Ideally, you should
use an erlenmeyer flask, but a 1/2 gallon or 1 gallon
growler/jug works well too. If using an erlenmeyer flask,
skip to step 2, if using a growler or jug, sanitize
it with homebrew sanitizer. Also make sure to sanitize
a bung and air lock. If using a growler/jug, have a
couple of pints of room temperature, filtered or distilled
water put off to the side.
- Boil water. If using an erlenmeyer flask, put 700ml of filtered or distilled water
into the flask along with 1/2 to 1 cup of dry malt extract, swirl the mixture so that it is
well combined, and gently put flask directly on high
heat until it comes to a boil. If using a
growler/jug, put 3/4 quart of water into a sauce pot and put over high heat until it is close to
a boil; When the water is close to a boil, add 1/2 to 1 cup of dry malt extract and stir or
swirl the mixture so that it is well combined.
- Boil wort. Once the water/malt extract mixture comes to a boil, allow it to do so
for approximately 15 minutes. You don't need a raging boil here, just a gentle, constant boil.
- Cool the wort. After the wort is done boiling, get ready to cool it. If using an erlenmeyer flask,
put some aluminum foil over the top of the flask, get a pot holder, pick up the flask, and put it into a sink of cold water.
add or drain water as necessary to keep the flask in a cold bath of water for about 15 minutes. If using a growler/jug,
get the couple of pints of room temperature water you had on standby and add it to the pot of hot wort; put a sanitized
funnel in the top of your growler/jug and pour the warm wort into the growler/jug; if the growler/jug is not between 60° - 80°,
put it in a cold water bath as described for the erlenmeyer flask.
- Pitch the yeast. Once the wort in your container is between 60° - 80°, carefully pitch the yeast into it, and
give it a good swirl to make sure it is well mixed. If you had aluminum foil on the top of your container, remove it and
replace it with a bung and airlock.
- Ferment and pitch the starter. Allow your starter
to ferment for an absolute minimum of 12 hours before
you pitch it into your batch of beer. Ideally, you should
give your starter 24 to 48 hours before it is used.
Your goal is to pitch the starter after it has shown
hours of fermenting acitivity and to also pitch it while
it is still visibly active. Before you pitch the starter,
give it a good swirl to make sure everything within the
container is pitched.
Sanitizing tips
There are many sanitizers and cleansers on the homebrew market
these days, and for the beginning homebrewer it can be a bit confusing
as far as knowing what chemicals do what and what is best for their
situation. Some chemicals both clean and sanitize, some only clean,
and some only sanitize.
For the beginning homebrewer, we highly recommend
using a product that both cleans and sanitizes. It's much
easier to deal with and it's more affordable. Two products
that are both cleanser/sanitizers are One-Step and
B-Brite. These products are nearly identical. They
both have the same dosage of 1 tablespoon per gallon and
they work in about the same time. A 30 minute soak (using
warm tap water) with either product will remove most organic
residue from your equipment. A 10 - 15 minute soak will
provide good sanitization. The only real difference between
the two is the One-Step claims that it's "no rinse",
while B-Brite does not. As far as we're concerned, it's
better to get yourself in the practice
to rinsing, regardless of the chemicals you're using... it's better to err on the side of caution.
Remember that when it comes to sanitizing, the easy
way out rarely pays off. DO NOT use your dishwasher to attempt
to clean or sanitize your equipment and/or bottles... it
will not work. Most cleansers and sanitizers on the market
work as a soak rather than a spray because the active chemicals
need a certain amount of contact time with the equipment
being sanitized. If you cut corners, at some point you're
beer is going to get infected, plain and simple. |
