🍑 AVENUE OF THOUGHT IS BACK! 🍑

A longtime favorite has made its return. Avenue of Thought is back on draft today, with fresh 4-packs hitting the cooler tomorrow!

This smooth and bright 7.3% NEIPA is packed with Vic Secret, Citra, Mosaic, and Galaxy, creating a layered, fruit-forward hop profile with just a touch of floral character.

We think it tastes like vine-ripened passionfruit and freshly juiced nectarines—juicy, tropical, and incredibly smooth from start to finish.

🍺 Available now on draft and in 4-packs to go!

Come welcome back Avenue of Thought!
