Twin Peaks Mountain Brewing is a German-owned brewery and beer restaurant in Tsukuba, Ibaraki. The brewery says it brews in line with German traditions and the purity law, while its taproom regularly serves a rotating selection of beers alongside food.

In its Instagram post, the brewery announced a special event for Saturday, June 20, to celebrate owner and brewer Carsten's 60th birthday. The program includes a brewery tour starting at 1:30 p.m., the release of Kanreki Beer (Altbier), a raffle with prizes, and the first Japanese/German Stammtisch starting at 6 p.m. The brewery notes that the tour can be done in English on request, but reservations are required.

The same post also shared the tap list for Thursday, June 4, from 6 p.m. to 11 p.m. The lineup featured Dr. Pilsner, Dr. Kölsch, Dr. IPA, Dr. Mozart, Dr. Weizen, Dr. Lemon Weizen, Dr. Munich Helles, Dr. Export, and Hedgebock. The list shows how Twin Peaks balances its everyday taproom lineup with special events that reflect its German-inspired identity.
