Hiran Infinity ∞ α-type【飛鸞 Infinity ∞ α-type】

Overall, the sake presents a dry, clean, and crisp style with a light and easy-drinking character. The aroma is gentle and delicate, offering subtly sweet fruit notes reminiscent of white peach. Rather than being overly expressive, the fragrance unfolds softly and gracefully. The acidity is milder than initially expected, without excessive sharpness, giving the sake a balanced and refreshing palate. It is characterized by its gentle fruit aromas and clean, crisp finish.

Based on the theme of “exploring infinite possibilities,” “type α,” the first release in the series, takes on a new challenge: brewing without the addition of cultivated yeast, relying entirely on the natural microorganisms and vitality present within the brewery.

This is a brewing method the brewery had long hoped to realize. Through a chance encounter with wild yeast naturally inhabiting the brewery, fermentation is allowed to begin and develop spontaneously, resulting in flavors born from a truly “unknown encounter.” Rather than actively controlling the sake and directing its flavor toward a predetermined profile, the brewery places its trust in the inherent vitality of nature and allows the process to unfold on its own. They believe this represents the most fundamental essence of sake brewing and one of its greatest fascinations. During actual brewing, even the brewing team was initially uncertain whether the wild yeast would successfully propagate through temperature control alone after the natural growth of lactic acid bacteria. The entire process required approximately 1.5 to 2 times longer than conventional brewing, making the moment when the yeast finally propagated naturally and the moromi began fermenting an unforgettable experience.

The brewery encountered a similar experience when challenging the traditional “Mizumoto” method this season. In today’s brewing environment, where successful fermentation into sake is often taken for granted, the tension and anticipation of wondering whether the sake will actually ferment successfully has become especially precious. It reminded the brewers that it is precisely this uncertainty and excitement that makes sake brewing so fascinating.
