Barley, specifically malted barley, serves as the primary source of fermentable sugars, which are crucial for yeast to produce alcohol and carbonation during fermentation. The mashing process converts starches in the barley into sugars, leading to a variety of flavors depending on the malt type.

Hops are used for their bittering, flavor, and aromatic properties. They contribute to the balance of sweetness from the malt and also contain preservative qualities, enhancing the shelf life of the beer.

Corn, while it can be used in brewing, typically functions as an adjunct to lighten the body or reduce costs, rather than as a main ingredient. This means that while it can be present in certain recipes, it does not share the foundational status of water, barley, and hops in beer production. Therefore, identifying corn as the ingredient that is
