The "FRUITS SOUR - strawberry -" listed on Choryo Shuzo’s online shop is described as "a fruit sour with the aroma of ripe strawberries, vivid fragrance, and a crisp, refreshing finish." It is designed to bring strawberry aroma, sweetness, and acidity to the forefront, while layering in a subtle milky note from lactose plus the soft texture of wheat malt and oats, aiming for a balance that works both before and after meals.

The style is listed as `Fruited Sour`. In addition to strawberry purée, the ingredients include Nara-grown strawberries. The hops are Barbe Rouge, and salt is also added, with keywords that evoke gose, Berliner Weisse, and kettle sour. The product page states that the filling date is March 18, 2026, and shipping begins on March 19, 2026.

It is sold as a set of six 360 ml bottles, priced at 4,290 yen including tax at the time of publication. It is handled as refrigerated cool-ship delivery with an additional fee, and cannot be purchased together with non-beer items. For freshness, the recommended drinking window is "within 30 days of the filling date," so it is best opened soon after arrival.

Choryo Shuzo, the brewer, is a sake company headquartered in Koryo, Kitakatsuragi District, Nara Prefecture, with its Koryo Brewery on site. According to official information, the company obtained beer and happoshu brewing licenses in 2021 and launched its craft beer business the same year. In 2022, it opened "Choryo Brew Park" next to the Koryo Brewery, sharing a local drink culture through both sake and craft beer. This strawberry sour release also seems to reflect that strong local character and seasonality in a direct way.
