How to determine alcohol content after kegging?

MrJames · May 4, 2011

I am new to this. I have my first beer kegged and have been sipping it now and again for the last few weeks. It is a Premium Blonde Ale. I added some lemon zest to try and get a bit of lemon flavor to it. It tastes good. How can I determine the alcohol content now that it is kegged?

(OG-FG)*131=%ABV

i.e
(1.040-1.010)=0.030*131=3.93 ABV

if you don't have the original and final gravities, most of us can't afford the equipment to determine that

That is what I understood from my investigation. It tastes strong to me. Guess it will be a mystery.

I don't have the original gravities. Next time I will.

Actually you can do alcohol with relatively modest lab equipment (a few hundred bucks) but most of us wouldn't take the time to do it.

there's something you can do with gun powder and explosives or something. probably better off just going with a recipe calculator to find an estimated abv.

AG or extract?
exact recepie may give you a ballpark answer for AG or a pretty exact one for extract

Just go on BeerSmith and enter recipe. That will give a close number.
