Totsuka Vinegar Brewery's Organic Japanese "Kokoro no Su" Set


Totsuka Vinegar Brewery's Organic Japanese "Kokoro no Su" Set


Made from organically cultivated rice and subsoil water from Mt. Fuji! Carefully matured with time and effort using traditional manufacturing methods!

"Kokoro no Su" [Supernatant unfiltered]
Contents / 500ml 

The "Kokoro no Su," meaning vinegar of the heart, made at Totsuka Brewery is a naturally brewed "Junmai (pure rice)" vinegar focused on "natural taste" and "natural aroma". Starting with the traditional method of koji (malted rice) making, alcohol fermentation and acetic acid fermentation takes 5 months and about 8 months to mature.

An excellent product created only by organically cultivated rice, Mt. Fuji underground water, and the action of koji mold, yeast, and acetic acid bacteria. Prepared in a jar, it is left to ferment and mature for a long period of time to create a mellow taste and rich aroma. The tastiness of the top clear produced by aging for a long time is sealed in the bottle as it is. By not using filtering agents or machines, we preserve the original taste and aroma of Junmai vinegar.

It goes well with various dishes such as hot pot, meat dishes, fish dishes, and vegetable salads.
