Iio Jozo uses only pesticide-free rice and spring water to first make their own sake which is then fermented into rice vinegar. This artisanal product uses 200 grams of rice to make a liter of vinegar - five times the minimum amount required by law.
Iio Jozo is a 123 year old vinegar company located on the Sea of Japan near the town of Miyazu. By controlling the process from start to finish and sticking to traditional production methods, Iio-san produces what is arguably the highest quality rice vinegar in Japan.
