Master Craftsman Rice Vinegar is brewed by the famous 300-year old vinegar maker, Tobaya Suten located in Fukui prefecture. Tobaya Suten is dedicated in vinegar-making in the traditional method. This rice vinegar is made of water, rice alcohol, koshihikari rice and koji yeast brewed slowly in big earthenware pots. Mild and aromatic, it is not an ordinary rice vinegar. We had this vinegar in a small bottle previously but now a 900ml bottle is available in Australia!
