This is my go-to for beer in Pittsburgh. For starters the owner and employees are always exceedingly friendly and helpful. In addition their beer selection is impressive for the size of the establishment. Black & Gold has boasts a plentiful selection of local and Pennsylvania brews, as well as beer from other brewing hotspots around the country, namely San Diego. Ballast Point, Mission, Green Flash, Coronado, and Stone just to name a few. There is always a great seasonal selection as well.
You'd be amazed at how often you can find the rarer beers here. When another distributor can't sell a high end craft beer it often gets rerouted to here. Anything special you had in mind that isn't in stock? Ask mgmt about reserving you a case!
