The Process Of Home Brewing

The normal batch of homebrewed beer is five gallons
in volume, which is enough for 2 cases, or 48 12
ounce bottle of beer. However, take it from someone who
has brewed beer before. I don't like sediment in my beer
so I often end up with anywhere from about 41-43 beers or so...
give or take + or - 3.

The typical homebrewed beer is produced by boiling
water, malt extract and hops together in a large
kettle and then cooling the resulting wort and adding
yeast for fermenting. Experienced homebrewers will
make their own extract from crushed malt barley by
a more complicated process of mashing the grain in
boiling hot water.

With both cases, the wort is boiled for 15 min to
an hour, to help remove some impurities, dissolve
the character of the hops, then break down some of
the sugar. The wort is then cooled down to a
pitching temperature.

The cooled wort is then poured into the primary
fermenter in a manner of aggression, as to aerate
the wort. Sufficient oxygen is also necessary for
the yeast's growth stage. The yeast is then put
into the wort.

The primary fermentation will take place in a large
food bucket or carboy. Sometimes it is left open
but often stoppered with the carbon dioxide gas
that's produced by venting through a fermentation
lock.

The process of making microbrews takes a lot of
time indeed, although you can take the necessary
short cuts once you learn more about how the
process works. If this is your first time brewing,
you should always use common sense and know what
you are doing.

One of the best things about making your own
homebrews is the fact that you can experiment with
ingredients and brew your own creations. You can
brew almost anything, providing you have the right
type of equipment - which can easily be found.

Microbrew - Beer Ingredients

The main ingredients found in beer are water, malted
barley, hops, and yeast. There are other ingredients
such as flavoring, sugar, and other ingredients that
are commonly used. Starches are used as well, as
they convert in the mashing process to easily
fermentable sugars that will help to increase the
alcohol content of beer while adding body and flavor.

Water
Seeing as how beer is mainly composed of water, the
source of water and its characteristics have a very
important effect on the character of the beer. A
lot of beer styles were influenced by the
characteristics of water in the region. Although
the effect of minerals in brewing water is complex,
hard water is more suited to dark styles, while
soft water is more suited to light styles. I
personally use distilled water in my brewing.

Malt
Among malts, barley is the most widely used due to
its high amylase content, and a digestive enzyme
that facilitates the breakdown of starch into
sugars. Depending on what can be cultivated locally,
other malts and unmalted grains can be used, such
as wheat, rice, oats, and rye.

Malt is obtained by soaking grain in water, allowing
it to germinate, then drying the germinated grain
in a kiln. By malting the grain, enzymes will
eventually convert the starches in the grain into
fermentable sugars.

Hops
Since the seventeenth century, hops have been
commonly used as a bittering agent in beer. Hops
help to contribute a bitterness that will balance
the sweetness of the malts. They also contribute
aromas which range from citrus to herbal.

Hops also provide an antibiotic effect that favors
the activity of brewer's yeast over the less
desirable microorganisms. The bitterness in beer
is normally measured on the International
Bitterness Units scale.

Yeast
Yeast is a microorganism that's responsible for
fermentation. Specific strains of yeast are chosen
depending on the type of beer produced, as the
two main strains are ale yeast and lager yeast,
with other variations available as well.

Yeast helps to metabolise the sugars that are
extracted from the grains, and produces alcohol
and carbon dioxide as a result. Before the functions
of yeast were understood, all fermentations were
done using wild or airborne yeasts.

Clarifying agent
A lot of brewers prefer to add one or more
clarifying agents to beer that aren't required
to be published as ingredients. Examples include
Isinglas finings, which are obtained from swim
bladders of fish and Irish moss, which is a type
of red algae.

Since these ingredients can be obtained from animals,
those who are concerned with either the use or
consumption of animal products should obtain detailed
information from the brewer.
