What is wild yeast?

Wild yeast, also known as native yeast or natural yeast, refers to the microorganisms present in the environment that can be used for fermentation in baking and brewing. These yeasts are typically found on the skin of fruits, in the air, and on grains, and can be harnessed to create unique and flavorful products.

Wild yeast is often favored by artisanal bakers and brewers for its ability to produce complex and varied flavors in their products. It is also seen as a more natural and traditional way of fermenting, as opposed to using commercially cultivated yeast strains.

Some examples of wild yeast strains include Saccharomyces cerevisiae, which is commonly found on grapes and used in winemaking, and Brettanomyces, which is known for its funky and sour flavors and is used in certain beer styles.

However, using wild yeast can be unpredictable and requires careful management to ensure a successful fermentation process. It is important to create a suitable environment for the yeast to thrive, as well as to monitor and adjust fermentation conditions as needed.

Overall, wild yeast fermentation can be a rewarding and creative process, leading to unique and flavorful products that reflect the terroir of the region where the yeast was collected.
