(og-fg) X ?

[taelmore]

I am confused, I have read that when calculating the ABV you should take the OG minus the FG then times that by 129, 131 and others, My question is what is the correct number to use when multiplying to figure out the ABv any Idea or what is the norm for home brewers ?.

 

[FishinDave07]

I do (OG - FG) * 131

 

[lapaglia]

I do ((OG - FG) / 7.36) * 1000
Its the formula I have used for ABV for a long time. It does produce a slightly different reading than the * 131. Perhaps because mine is a wine formula and not a beer formula?

Is there a tool to give a measurement rather than calculating the Alcohol content?

 

[taelmore]

Thank's If their is any other suggestions I would still like to learn more about it.

Thy trusty brewing software!

All the brewing software you will find will have several calculators as well as many other features but they are necessary if you don't want to get into software at this point.

Here is an online collection of brewing calculators that will come in handy.
