That's such a great feeling, eh? The tastes of my Cascadian Dark Ale that I had before bottling were fantastic; flat, but fantastic. I'm really digging how much you can tell about a beer by tasting the wort, tasting a bit of the transfer from primary to secondary, and on bottling.
The IPA I've got in the secondary smells amazing (you huff the airlock too, admit it!). Looking forward to getting that one in the bottle. It's got a combination of fresh, dry, and pellet hops so it should have some good character.
