Rice Vinegar: what every chef needs to know
Ask a seasoned cook about Rice Vinegar and you will hear about the mildest vinegar in commercial kitchens: 4–4. 5% acetic acid compared to 6–8% for white wine vinegar. That mildness is not a weakness but a precision instrument. In Japanese cuisine, rice vinegar is a go-to for sushi rice (sumeshi), sunomono salads and ponzu sauce. Komezu has a subtle sweetness from residual rice sugars not fully converted during fermentation. Black rice vinegar (kurozu) matures for a year or more in earthenware pots: deeper, less sharp, lightly caramel-like character. Kurozu is used as a dressing and health drink, not as a cooking medium. Sushi-zu is not pure vinegar but a blend of rice vinegar, sugar and salt in a ratio that varies by region and chef (classic Edo style: 5:1:0.5). Never substitute sushi-zu with regular vinegar: the pH and flavour are fundamentally different. Rice vinegar is also the base of ponzu alongside yuzu juice and soy sauce.

Frequently asked questions about Rice Vinegar
Is rice vinegar the same as sushi vinegar?
No. Rice vinegar is pure fermented rice vinegar. Sushi vinegar (sushi-zu) is rice vinegar blended with sugar and salt. Always check the label: some European brands sell sushi vinegar as rice vinegar.
Can I substitute white wine vinegar for rice vinegar?
In emergencies: use two-thirds of the amount of white wine vinegar and add a pinch of sugar. Acceptable for marinades, but not suitable for sushi rice where pH balance is critical.
What is black rice vinegar (kurozu)?
Kurozu matures for 1 year or more in earthenware pots and has a deeper, milder flavour with a light caramel note. Use as a dressing or health drink. Do not heat: the complex flavour evaporates.
At what temperature should you store Rice Vinegar?
Store Rice Vinegar at Kamertemperatuur (unopened and after openen), compliant with EU Regulation 852/2004 and Codex Alimentarius guidelines.

Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
