Forget pumpkin spice! Well, at least try to, since everything this season tastes (kinda) like a pumpkin -- Starbucks is testing out a new flavored latte with stout-like flavors, called the Dark Barrel Latte, and it's supposed to taste just like a cold glass of Guinness. There isn't any actual alcohol in the latte, but it's got a shot of caramel syrup and a shot of a new syrup, "stout", which has an almost chocolatey "roasted malt" flavor, according to Starbucks corporate, so it's close enough to the real thing that you'll feel like you're at the pub.
The latte is currently only available in test markets in Florida and Columbus, OH, but so far the response in those places has been positive, if you're a fan of both beer and not falling asleep (YOU KNOW WHO YOU ARE):
