About Bootstrap Brewing Company

Bootstrap was founded by local residents Leslie and Steve Kaczeus. They both left the high-tech industry to follow their dream of creating an adventurous craft brewery dedicated to producing a wide range of high quality ales and lagers.  The brewery opened its doors on June 20th 2012 claiming solstice as a birthday and anniversary.

Steve, who is a Mechanical Engineer and Program Manager by training, was an avid home brewer for over 20 years and graduated from the American Brewer’s Guild in the summer of 2011.  Leslie’s background is in marketing. In the short time since opening, they have laid down a set of award winning beers and have begun to brew fantastic classic beers and exciting seasonals including bold fruit and spice infused beer.

Our goal is simple – we want to make really great beer and have a lot of fun. We also love to rock out and our beer enjoys the best classic rock 24 hours a day which is why it’s so happy and delicious!  Did you notice that we have music pairings with our beer?
