I just introduced myself to Sierra Nevada Bigfoot Ale. I'm new to Barley wine style beer, but it tastes pretty good on a cold night. It's definitely a sipping beer with a thick fruity taste. At around 10% alcohol, one beer does me just right. I have managed to put down 3 in one night, but they just aren't enjoyable like that.
I highly recommending picking up a 6er to try on a chilly night.
