orca Ginza Brewery introduced an August-only Watermelon Sour in an Instagram post on August 1. The brewery described it as a first-time seasonal offering, built around a familiar summer ingredient.

According to the post, the beer starts from a wheat-forward sour ale base and is flavored with watermelon and coconut. Its slightly orange-tinted appearance is said to come from the natural pigments of the watermelon, and no coloring is used. The yeast choice combines sour and ale character, aiming for a bright acidity and a clean, refreshing finish. It is the kind of seasonal beer that fits hot weather without feeling heavy.

The tap list at the brewery shows a wide range of styles, including ORIGIN, Monde Lager, Ginza IPA, Weizen, BIERE DE GARD, Watermelon Sour, NEW ENGLAND IPA, Rauch, COLA SOUR (from New Zealand), and IRISH STOUT. That lineup reflects the brewery’s small-batch, in-house brewing approach in Ginza, where each tap offers a different expression.

orca Ginza Brewery is located in the basement of Shokin Building at 8-11-12 Ginza, Chuo-ku, Tokyo. Its official site lists opening hours as Monday to Friday from 16:00 to 23:00, Saturdays and holidays from 14:00 to 22:00, and closed on Sundays. As a seasonal release made at a downtown Tokyo brewpub, the Watermelon Sour neatly shows the brewery’s style and location.
