Wush wush is considered a rare variety, as it shares similar characteristics with Geisha but is produced in smaller quantities. By using native strains of microorganisms naturally present in the area, it expresses the unique terroir of the land. The fermentation process is conducted in a controlled environment, allowing for dynamic changes over time, similar to natural fermentation. This process, called Dynamic Fermentation, is a new and unique processing method that brings out a rich, complex sweetness.
