ume plum vinegar

CondimentsYear-round. Ume plum vinegar is a shelf-stable fermented product available throughout the year, though production occurs seasonally following ume fruit harvest in June.

Contains beneficial lactic acid bacteria from fermentation and provides electrolytes through its natural salt content. The fermented nature may support digestive health, though sodium content is notable at approximately 1000-1500mg per tablespoon.

About

Ume plum vinegar (umeboshi su or ume su) is a Japanese condiment produced as a byproduct of umeboshi (pickled Japanese apricot) fermentation. Made from the liquid that accumulates during the preservation of ume fruits with salt and red shiso leaves, it undergoes a complex fermentation process lasting several months to years. The resulting vinegar is distinctly tart, salty, and fruity, with a characteristic tangy and slightly sweet flavor profile that reflects its umeboshi origins.

The ingredient typically contains salt (approximately 10-15% by weight), acidity from lactic acid fermentation and citric acid, and subtle fruity notes from the ume fruit. Unlike distilled vinegars, ume plum vinegar maintains a naturally low acidity (around 3-4%) and obtains its distinctive flavor through fermentation rather than mere acid concentration.

Culinary Uses

Ume plum vinegar is a versatile seasoning ingredient in Japanese cuisine, commonly used to balance flavors in dressings, dipping sauces, and marinades. It is frequently added to sushi rice, noodle dishes, and pickled vegetables to provide brightness and a subtle fruity tang. The ingredient also features in traditional home remedies and wellness tonics, diluted in water as a refreshing beverage. Its combined acidity and saltiness make it effective for dressing cooked greens, simmered dishes, and cold noodle preparations without requiring additional salt.
