Ingredient
Korean Vinegar
식초
Romanization: sikcho
Vinegar in the Korean kitchen, from naturally fermented grain and fruit vinegars, such as persimmon vinegar, to everyday brewed vinegar. It sharpens muchim, pickles and the dipping sauce chogochujang.
Flavor
Brewed vinegar is sharp and clean. Traditional grain vinegars are rounder, with mellow sweetness and a light malty depth; fruit vinegars such as persimmon carry gentle fruit notes.
Origin & History
Korean vinegar grew up alongside Korean alcohol. Nobody knows exactly when it was first made, but the Encyclopedia of Korean Culture cites a Joseon saying, recorded in Jibong yuseol, that vinegar is simply ‘bitter wine,’ and reasons that vinegar must be as old as brewing. Goryeo-era texts mention vinegar in cooking and medicine, and the first Korean recipe for making it, a barley vinegar, appears in the 16th-century Gosa chwaryo.
Joseon cookbooks and household manuals record many kinds: grain vinegars from rice, wheat and barley; fruit vinegars from persimmon and jujube; vinegars from vegetables such as bellflower root; and honey vinegar. Jeungbo sallim gyeongje ranks vinegar second only to jang as a seasoning no household should be without. Making it was a careful, almost ritual task. Many households kept a vinegar bottle on the kitchen hearth, topped it up with leftover alcohol and shook it whenever they passed — which, as the encyclopedia notes, kept it warm and fed oxygen to the acetic-acid bacteria.
Modern vinegars fall into brewed vinegars made by fermenting grains, alcohol or fruit, and synthetic vinegar diluted from glacial acetic acid. Slowly fermented grain and fruit vinegars, persimmon vinegar among them, carry on the traditional styles. In banchan, vinegar balances sweet and salty in cucumber and radish muchim, pickles jangajji, and mixed with gochujang becomes chogochujang, the classic dip for raw fish.

Values from the Korean Food Composition Table (RDA, 2016 data). The same table lists brown-rice vinegar (현미식초) at 22 kcal and persimmon vinegar (감식초) at 10 kcal per 100 g; vinegar is used by the spoonful, so its nutritional contribution is negligible. Actual values vary with ingredients, portion size and preparation.
Health Benefits
- Flavor without salt or fat: A splash of vinegar brightens dressings and can reduce the need for extra salt.
- Blood sugar research: A 2017 meta-analysis of clinical trials found that vinegar taken with a meal modestly lowered post-meal blood glucose and insulin responses. Research is ongoing, and vinegar is not a treatment for diabetes.
- Acidity: Typical vinegars contain about 3–5 percent acetic acid. Drinking vinegar undiluted can injure the throat and stomach; a published case report describes esophageal ulcers in a teenager who drank an under-diluted vinegar beverage daily. Always dilute drinking vinegars well.
