Rice vinegar, as the name suggests, is made from fermented rice. It is clear vinegar with a soft mellow taste due to its low acetic content. It has been used in Asian cuisines for centuries. It lends itself to oriental dipping sauces and salad dressings and is especially exceptional in sweet and sour dishes. Japanese rice vinegar is mild, but the Chinese variety has a strong taste, which can be white, red or black, depending on the rice used. A small bottle of rice vinegar will go a long way and I think, it is worth to keep a bottle in the cupboard and experiment with its taste.
