Here's a little tool that might just help you with calculating the alcohol content of your brew. If your unsure of how to get the original gravity (OG) or the final gravity (FG) then see my section on

All you have to do is type the OG and FG into the boxes below then press return and Hey Presto, out falls your alcohol by volume (ABV), and alcohol by weight (ABW) which is less used in Britain and Europe.
