A richer taste and an exceptional bite with vacuum technology

Vacuum cooling allows you to chill sushi rice and rolls within minutes — without drying the surface or compromising the structure. This ultra-fast process locks in moisture, enhances natural sweetness, and delivers a richer, more satisfying bite.

Inside our vacuum chambers, rice undergoes a unique method called "cooking cold": by continuously lowering the pressure, the boiling point of water is reduced, causing a small amount of moisture inside the rice to evaporate. This evaporation draws out heat from within each grain, cooling the product evenly from the inside out.
As a result, the rice husk stays intact, the grains gently expand, and the surface texture becomes more open — creating sushi with fuller flavor, better mouthfeel, and longer shelf life.

How Vacuum Cooling Maximizes Sushi Shelf Life

Thanks to rapid vacuum cooling, sushi rice can be brought down to the ideal temperature of 30–35 °C within just a few minutes — leaving no time for bacteria to grow. Once the sushi is formed, a second cooling step quickly brings it to optimal storage temperatures. This two-stage process extends shelf life significantly, without sacrificing taste, texture, or quality.

Leading sushi rice producers across Europe trust Weber Cooling technology to protect their products. By cooling both the rice and the finished sushi, they achieve a sweeter flavor, a richer structure, and a longer shelf life — every time.
