A few recent favorites:
Stone Enjoy By 12/26/14 DIPA
Founders Dark Penance Imperial Black IPA
Goose Island Bourbon County Coffee Stout (which is very difficult to come by)
Green Flash Hop Head Red (growler)
I usually really enjoy Stone's beers (I was stationed at Pendleton for a few years, so it was right there), but the Enjoy By didn't impress me too much. The Goose Island Bourbon County Series are all good. I got to try all 3 of them at a Goose Island Tap Takeover at the Nashville Flying Saucer, along with the Lilith and a few more.
