The Trader Joe's winter blend is my favorite! And there's a cute little place in my hometown that makes a holiday blend called "Sugar & Spice" that's really good as well.
Dietrichs holiday blend was very delicious when I could find it, it's so smooth. Not so fond of Starbucks because it seems to have a sharp undertone or aftertaste. Haven't tried Peets this year but there is a Peets in town...Thanks for the heads-up, FitSugar! :)
