Barley, as a cereal grain, primarily consists of carbohydrates, proteins, and fibers, with each component playing a crucial role in its functionality in brewing and nutritional value.

Proteins are critical in barley as they contribute to the formation of enzymes during malting, which are essential for converting starches into fermentable sugars during the brewing process. The presence of carbohydrates, primarily in the form of starch, serves as the main substrate for fermentation, ultimately influencing the alcohol yield and the flavor profile of the beer. While vitamins and other nutrients are present, they are not as significant in terms of composition when evaluating barley's major components.

Carbohydrates, particularly, are more accurately classified as starches, which are central to the brewing process. Fibers, while present, are typically not quantified in the context of major components in the same way as carbohydrates and proteins and are less relevant in brewing than sugars.

Understanding the composition of barley is essential for brewers, as it affects malting, mashing, fermentation, and ultimately, the finished product. Hence, identifying proteins, carbohydrates, and fibers as the main components of barley is fundamental to appreciating its role in creating beer.
