Yeast is a single-celled organism that’s found all over the world. It’s most commonly used in the production of beer, bread, and wine, as it helps to convert sugar into alcohol or carbon dioxide. Yeast has been around for centuries, and is responsible for some of the oldest alcoholic beverages in history.
Yeast plays an important role in the brewing process. Yeast feeds on the sugars present in grains like barley and wheat, converting them into alcohol and carbon dioxide. It also helps to break down proteins within the grain, which contributes to the beer’s flavor and aroma.
There are many different types of yeast used in the brewing process, each with its own unique characteristics. Some yeasts work best at warmer temperatures, while others thrive in cooler conditions. Yeast is also responsible for giving beer its distinctive flavors – certain strains will produce fruity, floral notes, while others can contribute notes of citrus, clove, or banana.
