Port City Brewing Company claims the title for the oldest packaging brewing company in the DC area. You may wonder, what's there secret behind being successful for all these years? Some may claim its the legendary hopzooka, a piece of machinery created by the brewery's brewmaster that allows hops to be added to beer without ever being exposed to oxygen. You can spot this piece of magical beer machinery on a tour of the brewery, or simply enjoy the results of such a creation when you sip on one of the brewery's many hop-tastic beers. Just be sure to look for the pineapple on top of the Port City Brewing Company sign - this spiky fruit signifies that the brewery is open.
