In addition to these 12 Pittsburgh and Allegheny County breweries, nine breweries outside the county took part in the merger. In all, 21 breweries joined to make Pittsburgh Brewing Company the largest brewing operation in Pennsylvania and the third largest in the country. The combined facilities, worth about $11 million, provided a capacity of more than one million barrels. Greater efficiencies and more modern equipment made it practical to close many of the 21 breweries shortly after the incorporation without relinquishing capacities.
