At "Beer Ma Kitasenju," located about a two-minute walk from the west exit of Kitasenju Station in a corner of the drinking district, guest beers themed around red fruit were introduced. The post features two beers: VERTERE / Viburnum and B.M.B Brewery / Ruby Tint.

Viburnum is a sour ale made with boysenberries and white chocolate. It is described as featuring a vivid lactic-acid-driven tartness and a creamy finish. Rather than ending with fruit acidity alone, it layers in a sweet nuance, making it appealing not only to fans of sour beers but also to anyone looking for a dessert-like flavor.

Ruby Tint is a beer packed with strawberry puree and amaou soft-serve ice cream. It emphasizes a balance of strawberry tartness and sweetness, with a finish that clearly brings the fruit character to the forefront.

The shop has 30 standing seats and is easy to drop into alone. More than 1,000 kinds of craft beer line the interior, and it offers both drink-in and takeout. Snacks tailored to different flavor profiles, such as salty nuts and chocolate, are also available, adding to the fun of comparing each beer's character while drinking. If you're looking for fruit-forward sour beers in Kitasenju, this is one place worth keeping on your list.
