Is there a way to test the alcohol content of your beer?
Exactly the reason I was asking.
The actual formula is (OG-FG) x 131= ABV.
That's funny... is it honestly that easy??
What a jerk I am... For the last few years I've been calcing Alcohol By Weight and then using that to do ABV.
ABW = 76.08*(OG-FG)/(1.775-OG)
and then...
ABV = (ABW*(FG/.079))/100
Luckily I had it plugged into an Excel spreadsheet so all I ever did was just type in the OG and FG... but I still feel stupid.

If you have a precision scale, it's fairly easy. Add exactly 100 grams of brew to a small jar. Heat the jar in a waterbath at 180F. Monitor the temperature of the beer, when it goes over 175F all of the alcohol is gone. Weigh again. The difference is your percent alcohol by weight.
If you post the recipe you used, we could probably give you a really good guestimate.
