Question

Most commonly used substrate for industrial production of beer is
A. Barley
B. Wheat
C. Corn
D. Sugarcane molasses

Answer 1

Hint: Beer is produced by a process known as brewing, by steeping a starch source in water and fermenting the resulting sweet liquid with yeast. Water and a fermentable starch source such as malted barley are the basic ingredients of beer. Brewer’s yeast and flavored with hops is used to ferment most beer. Starch sources such as millet, sorghum and cassava are less widely used.

Complete answer:
Barley: In industrial production of beer, Barley is the most commonly used substrate. Barley is easily available and costs comparatively less. The starch source in beer is a key determinant of the strength and flavor of the beer and it provides the fermentable material for beer production. Barley malt is the majority of the starch in nearly all beer.
Hence option A is the correct answer.
Wheat: Wheat is not a commonly used substrate in beer production. But it is used sometimes in the production of beer. Wheat acts as a secondary source which aids in retaining the foamy head of the beer.
Hence option B is not correct.
Corn: Although corn is not used as the most common substrate in beer production, there is a type of beer produced from corn itself. Beer style made from corn is known as the corn beer. Corn beer is one of the traditional beverages in various cuisines. The best-known corn beer, called as Chicha, is widespread in the Andes and local varieties of corn beer exist elsewhere.
Hence option C is also not correct.
Sugarcane molasses: It is mainly used for sweetening and flavoring foods in various places. Although sugarcane molasses are not commonly used as a secondary source in beer production.
Hence option D is also not correct.

Hence, Option A. Barley is the correct answer.

Note:
The process of brewing has taken place a long time ago, since around the \[{6^{th}}\] millennium BC, and archaeological evidence has shown that emerging civilizations, including Mesopotamia and the ancient Egypt brewed beer. The brewing industry has been part of most western economies since the nineteenth century. The main steps of the brewing process are: malting, milling, mashing, lautering, boiling, fermenting, conditioning, filtering, and packaging.
