Unlock Brew Base, the brewery based in Kasukabe, Saitama, has announced BORDER, a new Coffee Ale set to go on sale on June 27. The beer comes in at 5.5% ABV and is presented as a release that sits between beer and coffee, with aroma and drinkability both in focus.

Beer details
- Style: Coffee Ale
- ABV: 5.5%
- Coffee used: Ethiopia Kochare Washed

The coffee comes from Kochare village in the Yirgacheffe region of southern Ethiopia. According to the brewery's description, the washed process brings a clean profile, alongside bright floral notes that suggest black tea, lemon, and bergamot. That gives the beer a clear coffee character while leaving room for the base beer to show through.

For this release, the brewery also worked with the owner who previously ran BORDER CAFE, discussing not only bean selection but also roasting and extraction methods. That point suggests a carefully built collaboration rather than a simple coffee addition.

Unlock Brew Base, which operates from Kasukabe, is using BORDER to explore a familiar but still interesting idea: how far beer can go when coffee is treated as a core ingredient. For both coffee drinkers and beer fans, it is a release worth watching after June 27.
