🍺🧋 Bobahead releases this Friday, September 11!

Meet our wildly creative new Thai milk tea inspired sour ale, brewed with real popping boba.

Thick, creamy, and orange in color, Bobahead pours like a b**r—but drinks like a Thai tea experience, with dark brown sugar boba resting at the bottom of the glass. Expect sweet, creamy tea flavors and rich Thai tea character, gently balanced by the bright, tart backbone of a sour ale.

And yes… this might be the first b**r designed to be enjoyed through a straw. 🥤

Grab a straw, embrace the weird, and get ready to meet Bobahead this Friday!
