Extract Brewing Process:
-
Sanitize, rinse and dry all of your
brewing equipment prior to brewing.
You can either use a sanitizer from your
homebrew supply shop or household bleach. If you're
using a sanitizer, use it according to the
manufacturer's instructions. If you're using bleach, it
must be regular, non-scented bleach and heavily diluted.
If cleaning with bleach, create a solution using
1 tablespoon per gallon of water. If
sanitizing with bleach, use 1 teaspoon per gallon
of water. It may not be necessary to rinse your
equipment after cleaning it with a sanitizer, but if you
are using bleach, you must rinse your equipment
several times with hot water to remove any traces of the
bleach. Some experts do not recommend using bleach
because it will impart off-flavors in your beer if you
don't rinse your equipment properly. Be guided by your
own counsel in this regard.
-
If you're using malt extract syrup, place the cans in a bucket or sink
filed with hot water for at least 15 minutes to make the
syrup easier to pour. (Needless to say, this step is
unnecessary if you're using DME.)
-
Bring at least 3 gallons of
water to a boil in the
brew kettle.
-
Once the water
reaches a boil, remove the brew
kettle from the heat source then stir in the
malt extract.
Removing the pot from the heat source to
stir in the extract
prevents it from burning on the bottom of the
brew kettle and imparting
unwanted burnt flavors into your beer.
-
Once the malt
extract is thoroughly dissolved into the
water, return the
brew kettle to the heat and
resume a boil.
You do not have beer just yet. At this
point, the water-extract solution is called
"wort" (pronounced "wert").
Not until the yeast is
added is it technically beer.
-
Once the wort is
boiling again, add 1 ounce of the Cascade
hop pellets.
Hops
added at the beginning of a boil will produce hop
bitterness in the beer. Bittering hops in extract-based
beers should be boiled for at least 60 minutes to obtain
optimum hop utilization. Because of the length of the
boil, all of the delicate flavor and aroma components of
the hops are boiled away,
so flavoring and aroma hops - often referred to as
"finishing hops" - are added later in the boil. One
option here is the use of a hop
bag - a nylon or muslin sack with a drawstring that
keeps loose hop particles from floating freely about the
boiling wort. While a hop bag
is not required, I recommend using one to keep the wort
cleaner, to make siphoning the
wort easier once the boil is complete and to cut
down on messy clean-up. Nylon
hop bags are reusable, muslin bags are not, so nylon
hop bags are a wise
investment.
-
Once the bittering
hops are added, you will boil
the wort for a total of 60
minutes.
Keep a close watch on the
wort to prevent it from
foaming up and boiling over. Boilovers are messy and a
tremendous pain in the ass to clean up. If your wort is
headed for a boil-over, simply remove the
brew kettle from the burner
until it calms down or reduce the heat.
-
After 45 minutes have passed since
the beginning of the boil (15 minutes before the end of the
boil), place 1/2 ounce of the Cascade
hop pellets into the
wort.
The addition of
hops at this point in the
boil produces hop flavor in the beer. Use another
hop bag if desired.
-
After 55 minutes have passed since
the beginning of the boil (5 minutes before the end of the
boil), place the final 1/2 ounce of the Cascade
hop pellets into the
wort.
The addition of
hops at the end of the
boil produces hop aroma in the beer. Again, a
hop bag is not a bad idea.
-
Once the 60 minutes are up, remove the
brew kettle from the heat
source, cover it with a tight-fitting lid and drop the
temperature of the wort as
quickly as possible.
Once the wort
is no longer boiling, it is highly susceptible to
contamination by air-borne bacteria, so it is essential
to make sure that the brewing equipment and environment
remain as sanitary as possible! For now, the easiest way
to do this is to place the brew
kettle in a sink full of cold water and ice cubes.
(You might also add water dropped to near-freezing
temperatures to your brew
kettle, but remember that your
brew kettle may not hold a
full 5 gallons of liquid and, even if it does, 5 gallons
of water is relatively heavy.) There are more effective
means of chilling the wort,
but for your first batch or two, an ice bath is
sufficient.
-
Once the wort
has cooled to approximately 70º F, siphon the
wort from the
brew kettle into the 5-gallon
plastic bucket.
The plastic bucket will be the vessel in
which you ferment your beer.
The vessel in which you begin the fermentation of your
beer is known as the primary
fermenter. Most experienced brewers conduct a
secondary fermentation, but for your first few batches
you don't need to worry about this. Just get comfortable
with the process down before adding additional steps.
Siphoning may sound hard if you've never
done it before, but nothing could be easier. The key to
a good siphon is placing the vessel you are siphoning
from at a higher level than the vessel you are siphoning
to and letting gravity do the rest. For example, I place
the brew kettle on a
countertop and the primary
fermenter on the floor. Connect the
siphon hose to the
racking stem and sanitize
as usual if you haven't done so already. Next, fill the
siphon hose with water and
clip it tight. (Your siphon
hose should have a clip on it to cut off the flow.
If not, placing your sanitized thumb at the end
of the siphon hose will
suffice.) Place the tip of the
racking stem down into the bottom of your
brew kettle and the end of
the siphon hose into your
primary fermenter. Release
the clip (or your thumb) and let gravity do the rest.
-
After the
wort has been racked to the
fermenter, pour enough
water into the fermenter
to reach 5 gallons, gently mix the wort to bring the
water into solution, then take an
original gravity reading
with the hydrometer.
The original gravity of
this beer should be around 1.045.
Specific
gravity is a measurement of the density of a
liquid relative to water. Water has a specific
gravity of 1.000. Anything with a
specific gravity
reading higher than 1.000 is more dense than
water. For the homebrewer, the
original gravity
reading will measure the amount of fermentable
sugars in the wort.
The higher the reading, the more fermentable
sugars that are present and the higher the
potential final alcohol content. Therefore, one
purpose of this reading is to determine the
alcohol content of your finished beer.
To take an
original gravity
reading, draw off a few ounces of the
wort into a
sanitized
hydrometer tube, drop in the
hydrometer and make
a note of the reading. If you're working with a
plastic bucket, this should be easy enough, but
how do you get wort
out of a carboy
without siphoning it? Remember how fascinated
you were when you learned that soda would stay
in the straw if you closed the top of the straw
with your thumb? Use the same concept here.
There are gadgets on the market to help with
this. Hydrometers
are only accurate at 60º F, so the reading you
get must be adjusted if the temperature of the
wort is not 60º F.
(See the Hydrometer Temperature Correction chart
on the measurements
and conversions page).
-
After taking your
original gravity
reading, pitch the yeast
into the fermenter.
"Pitching" is brewer slang for
adding yeast to
the wort. If your
fermenter is a
plastic bucket, simply pour the
yeast in. If
you're using a glass
carboy, pour the yeast in through a sanitized funnel.
-
Finally, seal the
primary fermenter with
an airlock and shake
the carboy vigorously
for a few minutes before starting
fermentation.
One of the keys to a strong,
healthy fermentation
is plenty of oxygen in the
wort. Shaking the
carboy aerates the
wort. Although there
are much more effective and less laborious
methods of aerating the
wort, this will suffice for now.
