Seasonal sour ale at Izuya Shoten

Izuya Shoten, a beer pub in Nakahara, Shinagawa-ku, Tokyo, has added a new limited beer from Minoh Beer: Grefru Sour. According to the shop announcement, it has arrived as a seasonal beer for the coming hot months, and availability is limited.

Grapefruit forward and refreshingly dry

Grefru Sour is a sour ale built around generous amounts of grapefruit. Its ingredients include malt, grapefruit, hops, and lactic acid, while the hop bill features Cascade, Citra, and Nelson Sauvin. The result is a beer that combines rich citrus character with a tropical hop impression and a clean, refreshing finish.

The beer keeps a crisp malt backbone, but stays light on the palate with a bright acidity. At 4.5% ABV and 22 IBU, it aims for easy drinkability rather than heaviness, making it a natural fit for the season.

A limited beer worth catching early

Izuya Shoten is the kind of beer pub where seasonal arrivals matter, and this release is a good example of that appeal. If you enjoy grapefruit-driven sour ales with a clean, summer-friendly profile, this is one to check while it is still available.

Because the beer is limited, it is best to confirm availability before visiting if you want to try it fresh at the shop.
