Rice vinegar pickles the green beans in our Sweet and Sour Pickled Green Beans, but don't confuse it with rice wine or seasoned rice vinegar. They each play different roles in cooking:
RICE WINE (also called aji-mirin) is slightly sweet and mildly acidic and helps balance salty ingredients like miso and soy sauce. Alcohol content is very low.
RICE VINEGAR is a delicate vinegar that rounds out the umami-rich flavors in Asian cooking. It works well in quick pickling and light, bright vinaigrettes.
SEASONED RICE VINEGAR is plain rice vinegar flavored with small amounts of sugar and salt. It is ideal for sushi rice and Asian-inspired salads.
