Milk stout question

[mark014294]

Wondering how I would get the true gravity of my stout. What I mean is that the lactose adds non-fermentable sugar so how does one figure out true gravities. Do I just take OG and FG like normal and figure total abv? Hope I don't sound dumb

The lactose adds unfermentable sugar, but you should have added it in the boil before you took your OG. So the amount of sugar points from lactose at the beginning of fermentation is the same as the amount at the end of fermentation.

So yes, those readings are "true" gravities and your ABV is figured based on OG and FG, same as any other brew.

Thanks for the info!

Yup - it cancels itself out, basically.

But, to answer your question... It depends on how much you add to what volume.

So, assuming you added 1 lb to 5 gallons, you can expect it to add about .006-.008 to your fg/og
