In addition to its usage as a condiment in sushi and other Asian dishes, black vinegar, also known as brown rice vinegar, is used in Japanese and Chinese culture as a health tonic. Made from unpolished rice, black vinegar takes from one to three years to ferment. During this process, the vinegar darkens, its flavor and aroma become more intense and the vitamin, mineral, amino acid and other nutritional content increases, vinegar and Asian nutrition experts say. Because of its reported health benefits, many in Japan and China make a drink concocted with black vinegar part of their daily diet.
