The Concept?

The concept is quite simple... make delicious tasting beers! The purest form of outlandish character. If there's one thing we know, it's good beer. We each have our own distinct opinions as to what we like. Ranging from insanely hoppy IPA's, rich creamy stouts, smokey porters, tangy sours, and pungent Belgian dubbels. Having a wide range of varying opinions is what makes this brewery diverse. You the consumer are guaranteed to find that perfect ale that suits your palette at Großen Bart Brewery!


For our Gluten sensitive friends, we are now using Clarity Ferm in our beers! The gluten protein present in beer is very proline-rich. Because this enzyme is a proline-specific protease, it chops up the gluten proteins so that people with sensitivities to gluten do not react adversely. MORE INFO

Each of our beers are associated with a different style of facial hair. Hold the can shaped glass up to your face to see how you would look sporting all the unique facial hair styles!

No facial hair? No worries! Our one of a kind hand-crafted beers are guaranteed to slap the beerd into you!
