INTRODUCTION
Beer has been defined as a beverage obtained
from alcoholic fermentation of a malted cereal,
usually barley malt, with or without starchy
materials and to which hops have been added.l
Hoyrup2 defined lager beer as a brew from barley
malt which is stored for a period of time for clarification
and maturing, but beer is also considered
as the generic term for all malt liquors variously
called beer, ale, stout, porter and lager3 The first
two definitions indicate the general use of cereal
malts in brewing practice, but the high enzyme
level of barley malt, as well as extensive research
studies conducted on barley,4,5 has earned barley
a unique position as the preferred cereal for brewing
beer.
