Brewery Background


Rio Brewing Co. is based in Shodenji, Kashiwa, Chiba Prefecture, and also has a base in Brussels, Belgium. In the post, the brewery explains its history: it began brewing in Brussels in 2015, started brewing in Japan in 2018, and expanded to Chiba in March 2021. It also mentions a 2023 equipment expansion and preparations in 2025 for producing cider, craft gin, and distilled spirits, underscoring the breadth of its beer-centered expansion.

As a spring seasonal release, BLOOM CORE appears to be a distinctly Rio-style seasonal offering that combines fruit, Japanese ingredients, and cherry blossom aroma.
