Mizubasho Pure Sparkling is a fully bottle-fermented sake made using traditional brewing methods and Yamada Nishiki rice. Development took nearly a decade. The main challenge lay in bottling the sake while fermentation was still active, then refining techniques to remove sediment completely without sacrificing finesse. After hundreds of trials, the current style was achieved in 2008, producing a clear sparkling sake with fine, stable bubbles and no residual cloudiness.
In the glass, it shows a pale, slightly milky veil with a muted grey-gold tone. The aroma is open and inviting rather than overt, moving between lightly tart fruit and florals. Banana, plum and citrus come through first, then jasmine, sakura and a light cereal note. The bubbles are soft and delicate rather than sharp. Freshness leads the palate, with yellow apple, banana and coconut supported by clean acidity. The finish is lightly saline, adding lift and length.
There is a clear umami presence, subtle but appetising, which helps the sake sit comfortably at the table rather than behaving like a novelty aperitif. Pairings suggested by the brewery include raw oysters, cured ham and caviar, while chefs have found it works well at the opening of a course menu, where its texture and restraint do not overwhelm food. Since its release, the sake has appeared on restaurant lists in Europe and other regions, including high-end dining venues. It has earned several international awards in sparkling sake categories. It is also made without animal-derived fining agents and carries vegan certification, a rarity in sake. Overall, it comes across as precise but understated, designed to work naturally with food rather than to stand alone.
