Vine-Glo was a grape concentrate brick product sold in the United States during Prohibition by Fruit Industries Ltd, a front for the California Vineyardist Association (CVA), from 1929.

The product was advertised with tips for preventing alcoholic fermentation, with one salesperson giving customers a very specific warning: “Do not place the liquid in this jug and put it away in the cupboard for twenty-one days, because then it would turn into wine.”
