This set pairs two sakes from Aramasa, the Akita brewery famous for reviving the historic No.6 yeast and now known for its minimal-intervention, kimoto-method `Colors` range. Ash is brewed from Kameno-o, a demanding heritage rice variety, giving a deep, slow-developing character; Cosmos uses Kairyo Shinko rice for a smoother, more approachable style. Both are fermented in wooden vats without excessive additives, reflecting the brewery`s purist, terroir-led approach to rice and technique. An interesting comparative pair for sake drinkers keen to explore how rice variety and method shape flavour.
