Miso & Soy source (fermented seasoning materials) brewed by sake brewery

One of the characteristics of “Washoku” (Japanese-style meals) is the usage of fermented foods. Miso and soy source are fermented foods essential for our table and are brewed by traditional brewers as part of agricultural products.

Making sake by Izumibashi is cooperation of agriculture and brewing business like “making sake from growing rice”. In the old time, the life style of Japanese farmers is self-sufficient and they brewed basic food materials for their dishes by themselves. So, they planted rice seedling at rice fields and sprinkled soybeans at the side of rice fields in spring, harvested rice and soybean in autumn and brewed sake and miso in winter. We pursued the agricultural style of old Japanese and decided to make not only sake but also miso by using the local breed of “Tsukui soybean” grown in Zama-city and Fujisawa-city of Kanagawa prefecture. One of the common thing between sake and miso is using ko-ji at brewing processes. We use the same ko-ji used for brewing sake, which is Yamadanishiki grown in Ebina. Please enjoy the rich flavor of miso using finest koji made by sake maker.

Local Soybean×Yamadanishiki

「Local Soybean」 = Tsukui Soybean

We commit to the local farmers to grow traditional breed of soybean from Tsukui-town in Kanagawa prefecture. This breed of soybean is suitable for making miso and precious breed as the production amount is very low.

Soybean has been used for making essential Japanese foods such as miso, soy source, tofu and Natto; however, self-sufficient ratio for soybean in Japan is now only 6% (in 2010). We would like to contribute the improvement of self-sufficiency of soybean by using locally grown materials.

 About usage of “Ginjo

For creation of miso we use koji, which made from approved “Yamadanishiki” polished to 70% and approved soybean. So, we use the naming of “Ginjo Miso”.

* To name “Ginjo” on the miso products, we need to satisfy one the followings; (1) use syobean higher than level 3, (2) use rice polished to more than 70% for making koji and (3) use wheat higher than level 2 for making ko-ji.
