AW, since you like the Abbey and 1554 from New Belgium (two of my favorites also) I would suggest that you try the Trippel. Much different than the darker ales, but a great brew. Be careful though, it packs a punch!

I've tried the Trippel and just can't get my tastebuds around it yet... must be that coriander in it. There's something in that 'bite' that I'm still trying to figure out!
