Having trouble figuring out alcohol content

MoonMaster · May 22, 2011

Just bottled my first beer today and I have been trying to figure out the alcohol content without much success. Can someone help me calculate this? I forgot to take an initial gravity reading so I dont know what it was initially but I have heard you can calculate it roughly with just ingredients. I used this kit:

Can anyone help me out here? The final gravity was 1.1.

Your Original Gravity was probably around 1.046, give or take. Your Final Gravity was (guessing here, since it was not 1.1) 1.010. (OG - FG) x 131 = .036 x 131 = 4.716 so 4.7%.

Cheers!
