Brewers' needs are essential ingredients for making beer. Yeasts, Hops, Malts, and Teabags are all necessary components for brewing beer. Yeasts are a type of fungus that helps to ferment the sugars in the wort, producing alcohol and carbon dioxide. Hops are a type of flower that adds bitterness and flavor to the beer. Malts are grains that are germinated and then dried, providing the sugars needed for fermentation. Finally, teabags are used to add flavor and aroma to the beer. All of these components are essential for brewers to make a quality beer.
