444 BEYOND, a beer pub in Higashimizue, Edogawa-ku, Tokyo, introduced a guest tap in its June 9 Instagram update. The featured beer, listed as the day’s No. 2 tap, was repubrew’s Purple Sweet Potato COOKIE WHEAT.

According to the post, the beer is a pastry wheat at 5.0% ABV. The shop describes it as having a gentle balance of sweetness and bitterness, with a clear purple sweet potato character. That makes it sound like a flavor-forward beer that still keeps the drinking experience light enough to approach as an easy first pour.

444 BEYOND also comes across as a compact, easygoing standing beer spot, with the shop even describing itself via hashtag as a "small standing bar in pistachio colors." For craft beer fans in Mizue, the appeal is clear: a neighborhood beer pub with a rotating guest tap and a direct, no-frills way to enjoy the day’s lineup.
