Comment on Secondary Lager Fermentation Slow?
Aarkon@feddit.de 2 months agoDoesn’t alcohol lower the density of the liquid, so that a hydrometer reading should have to be corrected as well to some degree? You sure now better than I do, but that was my impression.
Other than that, do you have a source for the numbers you mentioned? Something were I can go look stuff up myself, e.g. when I’m about to brew something very different?

Tldr of this measurement is that density is affected only negligibly (with low concentration of alcohol). Refractive index changes a lot.
These numbers were “discovered” by trying, maybe from some 15 yo Czech seminar my dad attended when he started. I just know that it works.
For sugar I am adding the least amount possible- it has some already ~3.5 °Bx and I don’t want bombs.
