300 Suns Brewing was really just an idea brought up years ago, that kept surfacing every time a brewery was toured, a GABF was attended, a new craft beer was tasted, a bottle of homebrew was shared on the back deck in the cool summer evening air. It was just a dream and one day (gulp), we worked up the nerve to make it a reality. We wanted to put our time and our work into something that brought joy to others the way those moments brought joy to us. And we wanted to give our community very meaningful ways that they could become part of the shaping of our brewery.

We are head over heels in love with Longmont, Colorado and the average of 300 days of sun we get to enjoy each year. Nothing pairs better with a beautiful sunny day than a fun, relaxing place to hang out and enjoy a craft beer.

      Can’t acknowledge this brewery enough! It now has Scratch Kitchen as well, so best of both worlds! Went for the first time last Saturday. Had great beer and the loaded mac n’ cheese! There was enough to eat and serve on the side of our family dinner later in the week! Took my oldest two there today and yet again, did not disappoint! Beer still tasted like it was just brewed and my kids raved over the house made root beer! I ordered the Nashville Hot Chicken with fries, my daughter is in love with the Scratch Burger and homemade potato chips, and my 11 year old ordered the Longmonster with chips because…well, you can’t go wrong with a Scratch Burger! We also tried the delicious house made cheese curds with homemade ranch and a red pepper dipping sauce! I also highly recommend trying their beer flights. There are too many good ones to choose from. You don’t want to miss out! We will definitely be back!
