So i use an online beer math calculator (link won't cut and paste right) to calculate my alcohol percentage in my beer. It seems to work well but i had a question about the alcohol by weight vs alcohol by volume.
What is the difference? Why do we not just pick one and use that one? And we are not measuring the alcohol by weight or by volume. We measure by density when we us a hydrometer (which I guess is kind of like measuring by weight but if you ask a chemist it is not the same.)
I know 1 is used mostly for beer and the other for spirits, but i can not remember which is which. Can someone clear that up?
