Hopkotan Brewing (account name: `@hopkotanbrewing`) unveiled its new beer "Seiran" in an Instagram post titled "2026.3.12 NEW BEER!!". The basic specs shown in the post are as follows.

- Style: Cold IPA
- ABV: 7.0%
- IBU: 65

This announcement came in reel format, with the location tagged as "Hopkotan Brewing Co., Ltd.". Although brief, the post clearly presents the style and numbers, suggesting a design centered on the sharpness and bitterness derived from hops.

Hopkotan Brewing is a brewery based in Kamifurano, Hokkaido. On its official website, it emphasizes its approach of "brewing with local hops," pursuing a wide range of beers in Kamifurano, a hop-producing region. It is also known for initiatives that foreground ingredient provenance, such as its "ORIGINALS" series, which uses 100% hops grown in Kamifurano.

"Seiran" can be seen as a new release within that context. Cold IPA is a style that draws interest for how it balances lager-like dryness with IPA-like hop character. The design of 7.0% ABV and 65 IBU suggests a beer that keeps satisfying body while aiming for a clean finish.

Details such as sales format and release timing should be confirmed in future official updates from Instagram and the company website.
