ok first of all, hello fellow homebrewers. I'm still new to this whole thing so i hope this isn't a stupid question.

So i forgot to check the gravity of my beer before fermentation, and also forgot to check it after. Is there still a way to find the alcohol percentage of my beer even though its done with all fermentation??

Thanks!

I'm thinking it's somewhere in the range of 0% to 20%.

Drink four pints of it as fast as you can, hop into your car, and speed past a cop. When he stops you, demand a blood test. You have about 6 quarts of blood in your body, so if you do the math you can get the alcohol concentration from your BAC.

Do you by chance have access to a gas chromatograph?

If you havent bottled yet take a hydrometer reading. Also post up the recipe and yeast type.

As fun as some of the previous posts are, you can't easily tell the ABV of a beer without knowing the OG and the FG. If you made an extract brew and topped off to the correct volume, chances are very good that the OG was exactly where it was supposed to be. So, if you know the final gravity, you can figure out the ABV. If you didn't take an FG reading, it can be estimated from the OG based on the attenuation of yeast you used. That'll get you close enough.

You can do this with a refractometer and hydrometer. Beersmith will do it and here is a link for an online calculator. From this you will get your OG, then you can calculate your ABV.
