On March 21, 2026, BAK Brewery announced its new release, NEWBIE, on Instagram. According to the post, the beer style is sour IPA, and the alcohol content is 6.0%.

The description says it is "as if it were grapefruit or pomelo," with a design that layers fresh, grapefruit juice-like tartness with hop-derived aromas reminiscent of pear. Its defining trait is a seasonal profile that foregrounds the refreshing brightness of citrus and fruity aroma.

BAK is a brewery based in Osaka, and its official website states that it follows an "original brewing style unconstrained by beer tradition or the mainstream." This NEWBIE release can also be seen as reflecting that approach through its tart sour IPA style.

The brewery operates locations in Osaka City (Horie, Umeda, Dojima, and Shinsaibashi) and also runs an online shop, continuously sharing local craft beer. As spring approaches, this new tart release, designed to be easy to keep drinking, is likely to draw attention both in stores and on tap.
