"Craft Beer Fest Maibara Menu Introduction ③" (posted March 12, 2026) revealed 3TREE BREWERY's booth details. The venue is the first floor of Maibara City Hall, directly connected to the east exit of JR Maibara Station, and the event will be held on Friday, March 20, 2026 (national holiday) from 12:00 to 19:00.

Based in Futaba-cho, Ibaraki City, Osaka Prefecture, 3TREE BREWERY is a brewpub that handles everything from brewing to serving in the local area. The wide lineup it has honed at its shop is being brought directly to the festival.

The six beers introduced this time are listed below.

- Flagship beer: RPG
- Flagship beer: Marcove
- IPA: Morishiki
- IPA: MIDNIGHT DANCING
- IPA: Bubble of Life
- Winter-limited beer: Kotatsu Memorial Day

In addition to two flagship beers, the lineup includes three IPAs and one seasonal beer, making it well suited to a festival built around side-by-side tastings. It should be easy to move from a light introduction to hop-forward IPAs, then finish with the seasonal release.

3TREE BREWERY is introduced as "Ibaraki's only brewery," and it serves as a way to bring the everyday brewpub experience to an event venue. For craft beer fans in the Kansai region, as well as anyone in the Maibara area who wants to sample multiple breweries from outside the area, this booth looks like a concrete option.
