Tasting Notes - Nuggets - City "Light" & FC(+)

Well. I think I both roasted too light and too dark with regards to the recommendations on the package from Sweet Maria's which recommended a City+ to FC on this particular bean. However, it's interesting to do a side by side comparison of the two. I prepared them both in my Chemex brewer with unbleached filters, pre-rinsed with a dose of hot water to get rid of some of the paper taste. The first thing I noticed was the smell. The darker roast had a noticeable stronger coffee smell, whereas the lighter roast hardly had any smell at all. The city roast also has a more sour taste to it. I wonder if this is the flavor of under-roasted coffee? The FC+ definitely what I would describe as a more integrated flavor, it seems that the taste of the whole sip is more well rounded and "earthy".
