orca Ginza Brewery announced an August 12 service day featuring an August-limited Watermelon Sour. In the Instagram post, the brewery describes the day as sunny after the rain and presents the beer as a bright, sweet-tart sour ale for summer.

The recipe was built from a bartender's idea: watermelon flesh, coconut, and citrusy hops layered over the refreshing acidity of a lacto-fermented sour ale. The brewery says it is designed for the season and will be sold until it runs out.

orca is a brewery restaurant in Ginza 8-chome, Chuo-ku, Tokyo, located in the basement of the Shokin Building. The day's tap list also included ORIGIN (Cask Ale), Ginza IPA, Watermelon Sour, Rauch, and IRISH STOUT. Course suggestions and message-based reservations were also available, making it a food-friendly, place-specific offering in central Ginza.
