Beer 0 - Final Gravity

I opened up the primary fermentation bucket yesterday for the first time. I leaned over to smell the beer and... got a face-full of CO2. Anyway, I measured the gravity of the beer. It was 1.010, right at the low end of the target based on my recipe. I can calculate the alcohol content by volume using this formula (from Wikipedia):

ABV = 132.715 (OG - FG)

Plugging in my original gravity of 1.044 and my final gravity of 1.010 yields an ABV of 4.6%, right on target for my recipe.

Today after work I'm going to check the gravity one more time to make sure that the fermentation is mostly finished, then probably move it to my glass carboy for a (short) week of secondary fermentation. It's probably not necessary, but I want to try using my new equipment. Plus, since I opened the primary, the CO2 layer dissipated and now there's air on top of the beer. Using my 5 gallon secondary carboy will leave much less airspace above the beer, lessening the chance of contamination and spoiling.
