A Japanese vinegar made with Umeboshi Plums, sea salt and shiso (parilla leaves). The red vinegar is fruity and very salty. Use over cooked or steamed vegetables, add to salad dressings and dips, and use for pickling. Eden foods quotes 4.3 percent acidity which may vary slightly by brand.
Look for this vinegar in Japanese markets and some health food stores like Whole Foods.
