beer composition

Beer is primarily made of four key ingredients: water, malted grains (usually barley), hops, and yeast. Water makes up the majority of beer's volume, providing the base. Malted grains contribute sugars that yeast will later ferment into alcohol and carbon dioxide. Hops add bitterness, flavor, and aroma while also acting as a natural preservative. Yeast is a microorganism that ferments the sugars, producing alcohol and carbonation. Together, these components create beer's unique flavors, aromas, and qualities, resulting in a diverse range of styles that appeal to different tastes.
