The Charm of “Mizu-ire”: UCC’s New Standard for Coffee

Many might not be familiar with the term “Mizu-ire” (water-brewed). UCC uses this term to describe coffee that has been carefully brewed using cold water over a long period. While it falls under the globally recognized category of “Cold Brew,” UCC uses “Mizu-ire” to express its unique technical prowess and the meticulousness of its process.

In just one year, recognition of the term “Mizu-ire” reached approximately 40% within Japan. By extracting slowly with water without applying heat, the coffee’s unpleasant bitterness and astringency are suppressed, maximizing its rich aroma and mellow mouthfeel.

In this renewal, the package design has also been refreshed to strengthen the brand’s identity. Based on a stylish two-tone color scheme, elegant curves reminiscent of a water surface have been added. When you spot this new design in stores, it is the sign of evolved deliciousness.

This is more than just a drink to quench your thirst; it is a cup that refreshes your soul. Let’s breeze through the upcoming hot Japanese summer with this refreshing companion.
