About
Originally isolated for mirin (sweet rice wine) production, K-10 is unusual among Kyokai yeasts for its high acid output and low ester production. While rarely used for mainstream sake, some innovative brewers have adopted it for creating distinctively acidic, food-friendly sake styles. The high acidity can create a white-wine-like character that pairs exceptionally well with rich Western cuisine.
