Fermented and aged in 100 year old cedar wood casks individually named after sumo champions, Marusho vinegars are steeped in authenticity. Sanbaizu rice vinegar is delicately flavoured with high quality natural ingredients - kombu (kelp), bonito fish flakes, mirin and mushrooms mixed with water from the Kumano mountains. Hand controlled fermentation results in a quintessentially Japanese flavour rich in umami. A long held secret of top chefs, this vinegar is ideal for marinating vegetables and adding to dressings and sauces.
