Brewing ingredients are the essential components used to create beer. The primary ingredients include water, malt, hops, and yeast. Water makes up the majority of beer and affects its taste. Malt, usually made from barley, provides sugars for fermentation and contributes to the beer's flavor and color. Hops are flowers that add bitterness, aroma, and flavor to beer, balancing the sweetness of the malt. Finally, yeast is a microorganism that ferments the sugars from the malt, producing alcohol and carbon dioxide. Together, these ingredients create the diverse range of beer styles enjoyed worldwide.
