Flat12 Bierwerks is a production craft brewery formed in 2010 located in the fast-growing Holy Cross neighborhood— just east of downtown Indianapolis. 

As a company, we embrace a laid-back, “work hard, play hard” mentality, fostering the creativity of each individual, and that’s no better exemplified than in our brewery. We like to think we strike a good balance between having consistent core and seasonal beers, while continually adding a variety of innovative specialty beers to the lineup. We don’t have a lot of allegiance to traditional styles, we brew what we like— and we like to make “ish-styles.”

The Flat12 production team brews for the pursuit of creative expression in a pint. There’s a lot of innovation, youth and passion in our brewery. We aren’t just brewing to quench the thirst, we brew to offer an experience. With their combined experience, thirst for innovation, and a passion for brewing, our liquid artists aim to help define the next generation of craft beer. As a team we continue the legacy of our namesake— a classic game-changing racing engine— and move towards a more revved up beer. 

Whether it’s through our commitment to brewing consistent, quality beer, buying from local hop farmers, hosting fundraisers, or helping educate the public on organizations that foster our shared values, we are committed to our customers and are an active participant in supporting the community they live in.

Thanks to our community reciprocating this support, our company continues to grow. Flat12 currently distributes across Indiana and Louisville, and recently opened a second location on the Ohio River in Jeffersonville, Indiana, just across from downtown Louisville.

What is this floating in my beer?

Over time, yeast and proteins in beer can begin to solidify and form sediment, haze or sometimes "floaties" in beer.

It can range in color from creamy white to tan and naturally occurs over time but does not affect the flavor of the beer. Of course if you are unsatisfied with any Flat12 products, please contact us HERE.
