15brewery, located in Horiuchi, Hayama Town, Miura District, Kanagawa Prefecture, announced its March 25, 2026 offerings on Instagram. This post is titled "<Sankaku to>", and the operation remains as before: standing service suspended, takeout sales only.

The five taps for the day are:

- Bottom of the Pond (Belgian style)
- Stout (dark beer)
- Orange Ale (fruit beer)
- Wheat Land (a wheat-forward beer)
- Raw Hazy IPA (IPA)

According to the post, Wheat Land and Raw Hazy IPA use baguettes from Miura bakery "Jyumugi" as part of their ingredients. Wheat Land is described as having a light drinking profile, while Raw Hazy IPA is characterized by citrus and pine-like aromas and bitterness created through a Raw Ale method that does not boil the wort.

Sales are basically filled to the brim into a sealable container brought by the customer. Carbonated PET bottles and glass bottles with screw caps are also accepted. Bring a bottle and follow the tap refresh from Hayama's small brewery.
