What ingredients are
used
to make beer? Here I list of the main ingredients used to
make beer. Other ingredients can and are used depending on the
type of beer you brew.
Water - Water makes
up about 90% of beer. Today
water chemistry can be changed and water can be purchased at your local
grocery store, but in the past many beers has unique flavor depending
on what part of the world the beer was made, in part due to the water
from that region.
Barley - Barley is a
cereal grain that is not particularly good for making bread, but
excellent for beer. Many types of barley are used from Two, Four
and Six Row barley. Two-row has a higher starch to husk ratio,
while Six-row has a higher concentration of enzymes and is more
economical. Barley must be processed into malt before it can be
used to make beer.
Malting: Malting
is done by soaking the grain, which causes the grain to start
germinating. When rootlets begin to sprout the grain is dried, crushed
and roasted. The roasting step stops the germination process,
leaving needed enzymes active and plays a large part in determining the
color and flavor of the final product.
Hops - Humulus
Lupulus, also known as hops are a
flowering vine which produce pine-cone like flowers that was once used
as a preservative
for beer (so I have been told). Today we mainly use hops for the
resins and essential oils located in there lupulin glands which add
flavor (bittering) and aroma. The bittering comes from boiling
the hops and can be distinctive depending on which hop variety is used
and how long you boil them. The aroma hops are used for aroma and
are added during the end or after the boil. Hops help balance the
sweetness of the malt. Many home brewers try to grow there own
hops since they are fairly easy to grow. Hops are usually dried
before use. Most hops in the U.S are grown in Yakima Valley in
Washington.
Yeast - Eat, belch
and sleep, that's the hard
life of yeast.. Yeast is one
of the most important parts of brewing beer. This unicellular
fungi, is what converts the sugars of the wort into CO2 and
alcohol. In
the process the yeast can also add characteristic flavors to the
beer. These flavors can be due to the particular yeast strain
that you use or the temperature that you ferment the beer. Many
home brewers have also started culturing there own yeast for economic
reasons and because it can be fun. The more you know about yeast
strains and how they are cultured the better and can only improve your
beer making. |
