Prohibition walkarounds

During the Prohibition period some people sold grape juice concentrate bricks. On the side of the packaging were a set of instructions labelled as such : “Caution, if you do this, the grape juice concentrate will turn into wine”. Mostly the instructions were about adding yeast to induce fermentation

Clever way to go around the 18th amendment ! Also, wine for religious purposes was legal too. I’m sure a lot of people became interested in religion at the time !
