Just minutes after opening its doors Friday afternoon, Cerebral Brewing’s new weekend-only taproom was already full. Customers ordered hazy IPAs and other beers from a makeshift bar and sat at brand new tables just a few feet from Cerebral’s brewing equipment. It was a good sign for brewery founder and co-owner Sean Buchan, who decided two years ago to take a risk on a part of the metro area that he really, truly loves: Aurora. Cerebral Brewing’s pop-up taproom is located at 9990 E.
