About `ACID TEST #001`


Takao Beer introduced a new sour IPA, `ACID TEST #001`, in an Instagram post dated June 5. The beer is listed at 4% ABV. It is now being served at the taproom, and the brewery says a canned version is also planned.

According to the post, the beer is brewed by adding fermented milk to the wort, carrying out lactic fermentation, and then fermenting with beer yeast. WPI protein is added afterward, making this a beer that focuses on milk-derived microorganisms and proteins. It is an experimental release that highlights process as much as flavor.

About Takao Beer


Takao Beer started in 2017 in the town at the foot of Mount Takao, with local residents building the brewery from scratch. Today, it operates from the `KO52 Brewery & Taproom` in Hachioji, Tokyo, and continues to make beers rooted in the Takao area.

The brewery’s official site emphasizes local sourcing, low-impact delivery by company vehicle, walking, and bicycle, and involvement in regional events and cultural activities. That broader approach gives its beers a strong sense of place.
