15brewery in Horiuchi, Hayama, Kanagawa, ran a bottle-fill-only service on Sunday, June 14, and placed five beers on tap. Draft sales are refill-only: customers bring a sealed bottle, and PET bottles or screw-cap glass bottles are accepted as well. Service hours were 2:00 p.m. to 7:00 p.m.

The lineup shows a wide range of styles and brewing approaches. "Numa no Soko" is a Belgian-style beer brewed with plenty of wheat malt, orange peel, coriander seed, chamomile, cloves, lime from Owase in Mie, and honey from Hachigoya in Nagai, Yokosuka. The beer is described as slightly sweet, gently tart, and complex, with a spicy aroma.

"Stout" focuses on deep, dark richness. "Raw Red Ale" uses a raw ale method with unboiled wort, aiming for the malt's natural heavy flavor and aroma.

"Dotanba Ale (Summer Orange Ale)" uses local summer mikan from Royal Fruit in Hayama and is presented as a refreshing fruit beer. "Raw Hazy IPA" also uses the raw ale method, with hop-driven citrus and pine notes plus a moderate bitterness.

Both "Dotanba Ale" and "Raw Hazy IPA" include baguette from Miura Pan-ya Mitsumugi as part of the recipe, giving the tap list a clear local connection. For a takeaway-only brewery in Hayama, the post highlights how regional ingredients can shape each beer's character.
