River City Brewing - WA: Oako-Coco Nitro

Official description from the brewery:
Sure Midnight Marmot Imperial Stout is good, but this one-off version goes to 11. We lovingly aged Midnight Marmot with Oak chips and Cacoa nibs and carbonated it with nitrogen. The result is a smooth, creamy head on a full-bodied stout complimented by chocolately flavors mixed with oaky, nutty bittersweet notes. This is a high intensity stout with lots of oak and cacao throughout the traditional stout malt flavors. M’mm M’mm extra good.
