San.publichouse in Uehara, Shibuya-ku, Tokyo, has updated its guest beer lineup with Spentage / Sour IPA from Teenage Brewing. The Instagram post describes it as a sour IPA made with cassis, framboise, and balsamic vinegar, and lists it at 5.0% ABV.

According to Teenage Brewing's beer page, Spentage leans into deep berry character, a bright acidic edge, and a light tannic finish. The beer also uses Citra, Hallertau Blanc, and Strata hops, which help support its layered aroma and structure.

Spentage is a collaboration between Teenage Brewing and Spent Grain. The beer brings together Teenage's recipe-driven approach and Spent Grain's technical expertise in brewery setup and support, making it a well-built sour IPA rather than just a fruit-forward novelty.

San.publichouse itself is a standing-style craft beer and tea bar, so it fits this kind of rotating guest tap well. For beer drinkers in Tokyo looking for something with clear fruit character and a crisp, structured sour profile, this is a tap worth checking while it is available.
