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.

[1] Fruit Industries ceased producing it in 1931 following a federal court ruling that making wine from concentrate violated section 29 of the Volstead Act.

[4] On the packaging, it included a very specific warning: "After dissolving the brick in a gallon of water, do not place the liquid in a jug away in the cupboard for twenty days, because then it would turn into wine.

[7] When Vine-Glo was introduced, the drys protested it, but Assistant Attorney General Mabel Walker Willebrandt ruled that it was legal under the Volstead Act, and the Bureau of Prohibition told its agents not to interfere with shipments.

Fruit Industries ceased making Vine-Glo a month later after the court decision was affirmed by the Director of the Bureau of Prohibition, who said grape concentrate would not be exempt under section 29.
