Methinks these guys are trying for a lifetime membership in the Society for Preservation of Beers from the Wood.
Heavy Seas' latest wood-barrel-aging experiment is right in keeping with its pirate marketing theme: 75 barrels' worth of Plank I and Dubbel Cannon in five white oak rum barrels from Prichard's Distillery in Tennessee. Expected release: mid-May (likely at the two festivals on May 14th, of course), and only locally in the Baltimore-DC region.
More on that beer here.
Heavy Seas also has a long list of upcoming events in May, including a beer dinner at Alexander's Tavern on May 4th, the official release of Plank I at Max's on the 17th, and firkins and beer dinners in Mt. Airy, Frederick, and elsewhere. Full list here.
