While it has become possible to produce vinegar in a short period, our producer is committed themselves to a slow, quiet stationary fermentation method. Following a single recipe that has not changed since their establishment in 1927.

They have not made any compromise on their ingredients either. As water is an important factor for making great vinegar. They spent over 10 years to find a good place to get natural deep water which is soft and suitable for producing vinegar.

The vinegar-making process begins with a thick sake made from just three ingredients: brown rice, spring water, and koji, a fermentation agent so integral to the nation’s cuisine that it has been named Japan’s national fungus.

The first step is to inoculate the brown rice with koji spores. The rice is steamed, allowed to cool slightly until it is warm to the touch, then sprinkled with spores and set to incubate in a warm, humid room.

During incubation, the spores feed on nutrients from the brown rice, producing digestive enzymes that will go on to play a key role in the fermentation process. Once the germinating spores have absorbed sufficient nutrients, they extend long, white filaments that spread throughout the rice, covering its surface. These filaments contain the vital enzymes needed to kick-start fermentation.

Once ready, the brown rice koji is combined with water and additional cooked brown rice and poured into vats to ferment. The koji enzymes convert the proteins, carbohydrates, and fats of the rice into amino acids, simple sugars, and fatty acids, then yeasts convert the sugars to ethyl alcohol. The end result is a thick sake called moromi that provides the base for Mitoku Organic Brown Rice Vinegar.

The moromi is mixed with spring water and seed vinegar from a previous batch and poured into casks, where it is left to ferment for a few months and then to age and mellow for several more. Once aged, the vinegar is filtered through cotton, flash-pasteurized, and bottled. The long vinegar-making process takes roughly one year from beginning to end.

Besides being a mainstay in salad dressings, pickling mixtures, and marinades, rice vinegar also perks up sauces, dips, spreads, and entrées. Japanese cooks add a little rice vinegar to cooked summer rice to prevent it from spoiling. To make beans more digestible, add a little vinegar to the cooking liquid once the beans are tender. Brown rice vinegar also enhances the flavor of grain, vegetable, and fish dishes. It can help balance salt and fats, and reduce cravings for strong sweets.
