Hi, I'm Mark Emiley on behalf of Expert Village.
In this next segment we are going to go over
the ingredients used in brewing. There are
four main ingredients in brewing. There's
malt, hops, yeast and water. Malt is usually
going to come in two different forms. You
have your malt extracts, you can get a dry
version which is a little more concentrated
than the liquid versions but a little more
expensive. Or, you can get the liquid extract
which is like a very, very thick syrup. The
other form of malts that you are going to
be adding to really kind of flesh out the
character of the beer that you are making
are specialty grains. These are grains that
have been roasted somewhat differently, maybe
steeped for a little while. And basically
they are going to add some of your more complex
flavors. When you get your specialty grains,
your local home brewing store will help you
mill them like this.
This will open up the grain allowing extraction
of the sugar and the color. Next we have hops.
And there are two major forms of hops that
are available. There is whole hops, which
you can see right here. This is actually just
the cone of the hop. And then there is also
pellet hops which is basically all of your
whole hops crushed up and then put into a
condensed form. The differences between the
two: whole hops tend to have a shorter shelf
life where pellet hops will last longer. You
will also get a slightly better extraction
out of pellet hops than you will out of whole
hops. However, for today's purposes in our
brewing session, we are going to be using
whole hops because they are a little easier
to get out of the wort. Hops can add three
things to your beer. First, they can add bitterness,
then they can also add flavor and finally,
they can add aroma. Hops, which are added
early into the boil for around a sixty minute
time frame will add bitterness as the flavor
and aroma components are boiled off. Hops
that are added in at a twenty to ten minute
time frame will add flavor. They also add
a little bitterness, but mainly flavor. And
finally, the aroma hops which are added usually
in the ten and under time frame down to actually
just steeping will add mainly aroma characteristics.
