Which set includes the four fundamental ingredients of beer?

• A. Water, barley, hops, yeast
• B. Water, barley, hops, malt
• C. Water, corn, hops, yeast
• D. Water, barley, wheat, yeast

Answer: (A)

Beer is built from four basic ingredients: water, barley, hops, and yeast. Water acts as the medium that carries everything and contributes minerals that can influence flavor. Barley provides the fermentable sugars after malting, giving the mash its sweetness and body. Hops add bitterness to balance sweetness and provide aroma and flavor. Yeast ferment sugars to produce alcohol and carbon dioxide, driving the transformation from wort to beer. The set that includes water, barley, hops, and yeast matches this essential quartet, making it the best choice. Other sets replace barley with different grains like corn or wheat, or substitute malt for barley, but the standard fundamental four are water, barley, hops, and yeast.
