North Carolina, like a lot of states, has a self-distribution cap that forces brewers in the state to partner with a wholesaler once they eclipse a certain mark in production. That threshold is 25,000 barrels in The Tar Heel State, and the majority of the state's brewers are nowhere near this limit. But there are a few that are knocking on the door, specifically, NoDa Brewing, Old Mecklenburg in Charlotte and Greensboro's Red Oak Brewery.
