Nano brewing indeed! I guess, technically this is Concord's first Brewery as they beat Cabarrus by a couple of months! As most people mention if you're approaching from the side facing the road, go through the entrance that says "US Matress", go to the back of the building through a sliding wooden door and High Branch is on the right. If you're already at Cabarrus, you can look across the way and see the sign (walk across the lot and up one flight of stairs, then make a Louie).
The high ceilings and exposed brick walls made me think this place would make an awesome loft apartment (or a Brewery). Admittedly I only tried one beer. Having read the descriptions, there was really only one I wanted to taste (two others I might have liked, had big black Xs through them on the menu). The Quick Learner Session IPA was solid but came across my palate as closer to a Farmhouse Hybrid - not bad, just different.
The craft beer scene has finally landed in Concord!
