Tokyo's Mitaka-based OGA BREWING COMPANY has introduced a new beer called Grefuru Summer in an Instagram post. The brewery presented it as a seasonal release suited to hot weather, with staff member Yoru appearing in the announcement.

Grefuru Summer is described as a sour ale built around a bright grapefruit aroma. The beer leans on a clean tart profile and juicy citrus notes, making it the kind of glass the brewery says fits a hot day. In other words, this is a refreshment-first beer rather than a heavy or malt-forward summer release.

OGA BREWING COMPANY operates from a neighborhood setting in Mitaka, Tokyo. On its official site, the brewery says its goal is to make beers that can surprise people who are new to craft beer and help more drinkers fall in love with it. That perspective helps explain why the brewery's lineup often moves across core beers, seasonal releases, and collaborations.

The Instagram post also listed the taproom hours: 1:00 pm to 8:00 pm on weekdays, and 11:00 am to 8:00 pm on weekends and public holidays, with last orders set for food and drinks. For drinkers in and around Mitaka, Grefuru Summer is one more reason to keep an eye on OGA's latest seasonal offerings.
