Top Ten Seasonal Beers.
Morning Edition, December 24, 2008 · Consider the libations of the season: Spiked eggnog. Mulled wine. What about a nice frosty Christmas beer?
Their list is okay... but how did they leave off Odell's Isolation Ale?
Tried Breckenridge Beer's Christmas Ale for the first time, which surprised me. It has cola notes but without the sweetness. With a porter or stout, I've never been fond of sweet additives... your vanilla porters or chocolate stouts don't do it for me. But BB's Christmas Ale is a completely different animal. Heavy but not thick, a bit of caramel but not syrupy or sweet.
