Hi I'm Mark Emiley on behalf of Expert Video. In this next segment we're 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 have a dry version which is a little more concentrated than the
dry version, so it's a little more expensive. Or you can get the liquid extract, which is
like a very, very thick syrup. The other form of malts you're going to be adding to really
kind of flush out the character of the beer that you?re making are specialty grains. These
are grains that have been roasted somewhat differently, maybe steeped for a little while,
and basically they're going to add some of the more complex flavors. When you get your
specialty grains, your local home brewery 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's two major forms of hops that are available. There's whole hops, which you can
see right here. This is actually just the cone of the hop, and there's also pellet hops,
which is basically all of your whole hops crushed up and then put in to a condensed
form. The differences between the two: whole hops tend to have a shorter shelf life, whereas
pellet hops would last longer. You would also get a slightly better extraction out of pellet
hops then you will out of whole hops. However, for today?s purposes in our brewing session,
we're going to be using whole hops, because they're a little easier to get out of the
wert. Hops can add three things to your beer. First, they can add bitterness. Then they
can also add flavor. Finally they can add aroma. Hops should be added early in the boil,
around the sixty minute time frame. We'll add primarily bitterness, as the flavor and
aroma components are boiled off. Hops that are added in the twenty to ten minute time
frame will add flavor. They'll also add a little bitterness but mainly flavor. And finally,
the aroma hops, which are added in the ten and under time frame, down to actually just
steeping will add mainly aroma characteristics.
