WeldWerks Brewing Co. opens the Greeley brewhouse for an Aged to Perfection tour and tasting, walking guests through barrel-aged and stout programs that put this Front Range brewery on the map. Small-group pacing keeps the focus on the beer and the process, with pours reserved for guests 21 and over. It is a rare look behind the tanks for WeldWerks fans. Tickets at Eventbrite.
