Rock Art Pumpkin Imperial Spruce Stout

Growler (Beverage Warehouse, Winooski, November 2006), sampled from a Chouffe tulip at cellar temperature -- the growlers are just labelled "Pumpkin Stout", bombers will have the longer name. Dark thick tan head forms massive nicely patterned lacing as it subsides above the opaque jet body....nicely balanced aromas of herbal/pumpkin and chocolaty roast/sugars, the cocoa becoming stronger with warmth, though I don’t detect a lot of sprucy/pine notes....body is moderately sweet, a bit vinous/grapy and lightly tart towards the finish, chocolate-espresso dominating with very little in the way of the vegetable named on the label that I could detect, some dry woody qualities towards the finish....mouthfeel unfortunately lets this beer down, it’s way too thin and attenuated, far too dry and even chalky at the finish and the low carbonation makes it rather fatiguing to drink....another mixed sample from this brewery which seems often to have good ideas but poor execution. Will try a bottle when I see it to let the half-dozen people reading this know if it might be worth trading for (ooh, new Imperial stout, must have...).
