Picking up aromas does take practice. And if the beer is too cold, you're not going to get much. If you don't already, pour the beer fast enough to get an inch or two of head. This will release more of the aroma. Then if you can't identify what's going on, try looking up some reviews and seeing what you can find. Lower quality beers won't yield much, but quality and high abv beers should have a lot going on. Cigs are definitely not going to help though. I had the 1554 one time. Seemed pretty good. Somewhat of an odd style, since the renowned Belgian dark ales tend to be dubbels and quads, which are much stronger. I should give this another try, even though I find the rest of New Belgium's lineup a bit tiresome.
