Hanseniaspora is a genus of yeast that is commonly found in various environments, particularly in fruits and fermented products. These yeasts play a significant role in the fermentation process, contributing to the production of alcoholic beverages and other fermented foods. They are known for their ability to thrive in high-sugar environments, making them important in winemaking and brewing. The genus is characterized by its unique morphology and genetic traits, which differentiate it from other yeast genera. Hanseniaspora species are often studied for their potential applications in biotechnology and food science, as they can influence flavor and aroma profiles in fermented products.
