Rikuu 132 from Uyashinai and the character of 2025
Rikuu 132 was developed in Akita during the Taisho era from Kame-no-O and Aikoku, and is also known as Ai-kame. It is also known as a rice that Kenji Miyazawa encouraged people to cultivate. EARTH uses Rikuu 132 grown without pesticides in Uyashinai, Akita.
Polished to 50%, fermented by kimoto with Association No. 6 in cedar vats, pasteurised and bottled undiluted at 13% ABV. The 2025 vintage is a single-lot bottling without blending, described as having the firm character of Rikuu 132 and a finish with gentle astringency.
Specifications and tasting notes shown here describe the 2025 vintage. If the supplied lot differs, the bottle label takes precedence.

How it tastes

The 2025 aroma profile suggests Shine Muscat, white flowers and milk, supported by gentle cedar notes.
Soft sweetness, restrained umami and juicy acidity meet herbal and conifer-like astringency from the cedar vats. The 2025 finish shows the strength of Rikuu 132 and a gentle, lingering astringency.

Akita rice, kimoto and cedar vats
Aramasa was founded in Akita in 1852. Association No. 6 yeast was isolated from its fermenting mash in 1930. Akita-grown rice, kimoto and cedar vats underpin its brewing. The Colors and PRIVATE LAB products presented here use No. 6; ASTRAL PLATEAU ferments without added yeast.
The brewery returned to cedar-vat brewing in 2013 and began passing on cooperage skills in 2016. It established its own cooperage in 2024 and transitioned to Akita-cedar brewing vessels. The brewery uses 50 Akita-cedar vats.
Colors is the pasteurised core line expressing differences between rice varieties. PRIVATE LAB explores four styles: kijoshu, high-acidity sake, low-alcohol sparkling sake and sake made with minimally polished rice. ASTRAL PLATEAU shares three foundations: a single rice variety, new cedar vats and fermentation without added yeast.
