Very first impressions of this beer was that it was just another heavy porter that promises chocolate or vanilla accents but ultimately fails to deliver. After a few sips though, my impressions changed a bit. After I'd gotten used to the oakiness of the Yeti I was able to better pick up on the chocolate flavor. The one word that comes to mind to describe this beer is bittersweet... The chocolate flavor is definitely more of a dark chocolate flavor, which isn't my preferred chocolate but it's probably the best choice for brewing - especially when there is oak involved. The bitter chocolate and the rich oak flavor go well together and have an interesting balance in this beer. Speaking of bittersweet, this dark chocolate and oak combination made me realize that while they weren't the flavors I was expecting, my expectations were probably unrealistic. I mean, would a milk chocolate oaked stout work? Probably not as well as you'd think...
