Tag: Natural yeast sources

In nature, yeast cells are predominantly found on ripe fruits like grapes, which have been instrumental in winemaking and brewing since ancient times. This natural occurrence on sweet, fermentable surfaces provides a starting point to understand where brewers yeast, a domesticated strain of *Saccharomyces cerevisiae*, originally came from.

According to scientific research, yeasts are ubiquitous in nature and are frequently isolated from sugar-rich materials, with fruit skins being one of the most common habitats. This naturally occurring yeast is the basis for many traditional fermented foods and beverages, from wine to bread starters.
