Asamai sake brewery / 浅舞酒造株式会社 of Akita prefecture was founded in 1917. Asamai sake brewery / 浅舞酒造株式会社 is a brewery of pure rice sake made only from local rice grown within a radius of 5 kilometers (about 3.1 miles). Their storehouse is located in the Yokote-bonchi of Minase-Nruse, the origin of the Ouu mountains which is famous for its water. The water they use to prepare their sake is one of the Biwanuma cold springs that rises here. The Amanoto brand is a treasure of the Yokote-bonchi. "Amanoto Sikly / 天の戸 シルキー | Tokubetsu-junmai roughly filtered sake" is an undiluted sake that features the mild tartness of citric acid and carbonation created by secondary fermentation in the bottle. The somewhat vigorous carbonation, which emphasizes its refreshing quality, and the brisk, lemony finish produced by the citric acid of the white koji are exceptional. This sake has won the top gold prize of the Fine Sake Award 2017 for three years running.
