3 days ago · Levain, or levain starter, is a leavening agent made from a mixture of flour and water and used to bake bread. The flour and water mixture takes on the wild yeasts in the air, and ferments. (You can also add commercial yeast to create a “prefermented” levain. This kind of levain is much quicker to make, and is meant for a single use.) It takes about 10 minutes to properly hydrate the yeast and you have to take the time at this step before incorporating yeast with your other ingredients. When making bread, your recipe might suggest to let the active dry yeast soak in warm water with a pinch of sugar. The sugar is to feed the yeast and get it going. Yeast have the most important job in brewing: they start with sugar and break it down, leaving alcohol, carbon dioxide, and a variety of flavors. The importance of yeast often gets forgotten when conversations about beer turn to grain and hops, but yeast actually have the potential to contribute more unique flavors to your beer—both good and bad—than any other ingredient.
