How Wine Bricks Saved The U.S. Wine Industry During Prohibition"If you were to purchase one of these bricks, on the package would be a note explaining how to dissolve the concentrate in a gallon of water. Then right below it, the note would continue with a warning instructing you not to leave that jug in the cool cupboard for 21 days, or it would turn into wine. That warning was in fact your key to vino, and thanks to loopholes in Prohibition legislation, consuming 200 gallons of this homemade wine for your personal use was completely legal, it just couldn’t leave your home – something wine brick packages were also very careful to remind consumers. Besides the “warning,” wine brick makers such as Vino Sano were very open about what they knew their product was to be used for, even including the flavors – such as Burgundy, Claret and Riesling – one might encounter if they mistakenly left the juice to ferment."
