Number of bottles of blue wine sold since its launch last summer. Made by a Spanish wine company called Gïk, the wine comes from red and white grapes grown in north central Spain, including Rioja. Spanish authorities recently banned sales of the sweetish drink since blue wine is not among the 17 approved types of Spanish wine. The company argues that the blue wine’s composition is 100% grapes. The color of the wine comes from indigo, a dye extracted from the Isatis Tinctoria plant. A non-caloric sweetener is added as well.
