What the Ale?
Deciphering the different styles and characteristics of beer

M

erriam Webster Dictionary defines
beer as an alcoholic beverage usually made from
malted cereal grain (as
barley), flavored with hops
and brewed by slow fermentation. Beer has been
around a really long time,
first being produced in
Egypt and Mesopotamia
around 5,000 BC. Modern
beer has European roots.
Beer became popular
amongst all classes of citizens in areas where grapes
for wine could not easily
be grown. All beer is made
from four basic ingredients: grain, yeast, hops
and water. From these
ingredients hundreds of
styles of beers are made -
but they are all either ales,
lagers or hybrids.
To your average restaurant patron, the
characteristics they'll notice in the different styles of beer are how they taste,
smell and look. Ales tend to have more
of a "fruity" flavor and lagers lend themselves to having more of a "crisp" taste.
The scientific difference between ales
and lagers comes down to the strain of
yeast used to ferment the beer. Ales were
the first beers brewed using Saccharomyces cerevisiae yeast, for example. And
they were the only styles brewed until
lagers came along a few centuries ago.
Lagers only started being brewed after
the discovery of the new world and a
new strain of yeast, Saccharomyces pastorianus, hitched a ride on trade ships
traveling back to Europe from North
America. The difference between the
two yeasts used is all about the tempera-

tures at which they convert the sugars
in beer wort to alcohol. Lager yeast can
work in colder and warmer temps. Ale
yeast can work only in warmer temperatures.
Popular ale styles include Pale
Ale, India Pale Ale, Brown Ale,

Porter, Stout, Hefeweizen, Kolsch, Gose,
Sours & Barley Wine. Pilsner, Märzen,
Dortmunder, Bock, Dopplebock and
Light Lagers are all popular lager styles.
Hybrids include Fruit Beers, Pumpkin
Beers, some Wheat Beers, Barrel Aged
Beers and Smoked Beers.
Several terms are used to describe the
characteristics of beers. ABV and IBU
tend to be two of the most commonly
used terms. ABV means "Alcohol by
Volume" and is used to express how
much alcohol is in beer. The ABV of
mass-produced light beers is typically in

the 4-5 percent range. Most
IPAs have a higher ABV of
6-10 percent. Porters and
Stouts range from 7 percent
on the low end to as high as
14 percent. Barrel-aged beers,
which are aged in barrels that
bourbon and other liquors
were first "aged" in, actually
gain additional ABV from
the bourbon or liquor trapped
inside the porous wood staves
of the barrel. The ABV of
Barrel-aged beers can climb
upwards of 20 percent. The
Higher the ABV, the greater
the intoxicating effect.
IBUs are International Bitterness Units. This describes
how bitter a beer is. Major
lagers such as Miller Lite or
Bud Light tend to have a low
IBU rating that is usually less
than 10. "Hoppy" beers such
as some pale ales, almost all
IPAs, Double IPAs and some
seasonals tend to be more bitter and
have higher IBU ratings. For example,
Double and Triple IPAs can have IBU
ratings well over 100. Scientists and
experts argue that our taste buds can
not detect differences in bitterness for
IBUs over 70. True beer geeks will go
even deeper into describing beer. They'll
describe color in terms of SRM (Standard Reference Method) and discuss
the Esters and Phenols that are yeast
fermentation byproducts that affect beer
flavor.
We'll dive deeper into the popular
styles of Ales, Lagers and Hybrids
next month! Enjoy a craft beer or two
between now and then...Q
