"DATE SEVEN" is named after the seven Kurabito, each from distinguished brewery, in Miyagi ken who join the project. The unique selling points include 33% Seimai-buai, using 藏之華 as ingredients and fermented with inoculated DATE SEVEN yeast strain. Each participating brewery take the responsibility of one particular step of the brewing process and the role is swapped between them every year. The product is released officially at 7pm, July 7 each year. Interestingly, the latest 2016 is a sparkling Sake.
"59 brewing" is a new co-venture project which stemmed from Nagano ken. Five young Kurabito who born in 1984 (equivalent to Shōwa 59), each create a unique expression with 59% Seimai-buai. The annual theme of packaging is different to cope with the style of particular vintage, and this ambitious project is released on May 9 annually.
Sakeiku Collection, founded by Mashidaya in Tochigi, is different from other Sakes as it aims at sake education. Eight breweries in the alliance each has made sake which themed with various topics like yeast, rice, etc. Sakeiku also carefully designed a manual providing relevant knowledge and information, as well as recording some problems they encounter along the brewing process, resulting in a more interactive learning environment for the consumers. Sakeiku collection is highly acclaimed by a number of Sake lovers and tasting the collection is somehow like attending a self-learning lesson.
Sake has remained dormant for quite a long time. The emergence of Co-venture Sake actually injects vibrant and new perspective into the market. A variety of Co-venture Sake aim to conquer the global market, showing the ambitions and vision of the group of young Kurabito. Co-venture Sake at the same time sets a new rule between the tradition and the novel. Kurabito can take their part in the co-venture product and at the same time produce their own Sake, without any conflict of interest. I believe Co-venture Sake was absolutely an indicator of big trend in the future.

「DATE SEVEN」取名自縣內造酒的7位勇者,是宮城縣內7家酒藏所開發的共同酒。特別在於,以33%精米步合、藏之華酒米,及特意為此款酒開發全新的DATE SEVEN酵母作為基本。酒造各自負責一部分的釀造工序,而負責的崗位亦會每年交替轉換。於每年的7月7日下午7點發表,2016年的DATE SEVEN則是氣泡版。
