Open fermentation

Open fermentation is a process used in brewing, winemaking, and other fermentation industries where yeast and microorganisms are allowed to interact with the air and natural surroundings in a large, exposed vessel. This technique can enhance the complexity of flavors, as wild yeasts and bacteria from the environment contribute to the fermentation. While it can lead to unique and interesting products, it also carries a risk of contamination by unwanted microbes. Open fermentation is often employed in traditional methods to produce artisanal beverages, emphasizing natural processes and local characteristics.
