The first batch is an old-style English Ale simply named "Plank I". To my knowledge this is the first production batch within the "old ale" style that Heavy Seas has put out. The wood used for this beer is yellow poplar and was toasted over charcoal to release and impart some unique flavors. Poplar is usually associated with desirable flavors or aromas so this will be an extremely different beer.
For more information on the English old ales check out BeerAdvocate.com's explanation of the style here. Some old ales that can be found on shelves now are Fuller's Vintage Ale, Founders Curmudgeon and Old Peculier from Theakston. Old ales are very similar to barley wines in color, flavor profile and alcohol content. The tend to age quite nicely.
Look for Heavy Seas Plank series to be released sometime this Summer or Fall in 22 oz. bottles and limited draft.
