In designing our tap room, we focused on recycling, reusing and repurposing. About 90% of the tap room consists of repurposed items and materials.

Join the IRB Club and receive your own stainless steel member growler. Our membership is for the life of our brewery. One time purchase = lifetime of hoppiness.

We specialize in small batch craft beers.

Our tap room offers a unique and inviting space for parties and events. The tap room can be reserved for groups up to 40 people.
