The traditional fermentation of Vinegar is carried out in large clay jars (Sangoku wagame) amongst the beautiful valley of Aya town and so the Brand name “YAMADAI”. This process has been in practice since the foundation of this brewery was laid in 1930.
We use organic rice which is cultivated in a clean environment free from chemicals and pesticide.
