A sour ale built around upcycled ume and red shiso

Better life with upcycle, based in Ebina, Kanagawa, has released Ume Shiso Sour Ale. The 350 ml can is priced at ¥572 including tax. Classified as an American-style Sour Ale w/ Ume, Red Shiso, the beer has an ABV of 4.5% and an IBU of 14.

The beer uses Beni-sashi ume from Fukui Prefecture that had been used in making plum liqueur, together with red shiso used in a cider made with Fukui’s traditional Kida shiso. After completing their original roles, both ingredients were upcycled into a new beer.

Umeboshi-like acidity and layered hop character

Ume, red shiso, and acidity from lactic acid bacteria form the core of the flavor. The combination suggests the character of a red pickled plum, bringing a refreshing sourness with a deeper, savory-fruited dimension from the ume and shiso.

Triskel and Idaho 7 hops add another layer, contributing apricot-like fruitiness and floral aromas. These hop notes complement the Japanese ingredients and keep the beer from feeling defined by acidity alone. On the finish, bread and malt-derived graininess spreads across the palate, leaving a soft cereal impression.

The beer is pink in color, giving it a friendly, distinctive appearance. It is sold refrigerated, and the brewery notes that yeast-derived haze may occur without affecting quality.

From a century-old bakery to sustainable beer

Better life with upcycle draws on a bakery founded in 1923 and its ongoing efforts to give new value to food that might otherwise be discarded, including bread crusts. The brand describes its approach as a dual craft of boulangerie and brewery. After working with brewers across Japan, it now also produces beer at its own brewing facility in Ebina.

Ume Shiso Sour Ale expands that upcycling story beyond bread, connecting ingredients from plum liqueur and cider with modern sour-beer techniques. Its combination of umeboshi-like acidity, red shiso, fruit-forward hops, and a bready malt finish makes it a compact expression of the brand’s sustainable approach to brewing.

Keep refrigerated. Alcohol consumption is prohibited for anyone under 20 in Japan.
