Some of the coffees I'm really liking now:
Mr. Espresso - http://www.mrespresso.com/
This has a great smoky flavor. Really enjoy the flavor of this one.
Blue Bottle - http://www.bluebottlecoffee.net/
This one is interesting. Pretty pricey, but fun every now and then. I've tried a good number of their coffees and while they aren't always my favorite in flavor, but there is a unique character in their coffees that, I believe, comes from their philosophy of keeping things fresh.
