A Spanish startup with no winemaking experience, Gik, is challenging the world to try its innovative blue wine. The blue colour is obtained by using indigo, extracted from the Isatis tinctoria plant, and anthocyanin, a pigment found in grape skin. The product also contains a non-calorie sweetener. All in their 20s and admittedly averse to tradition, Gik’s members selected the wine industry as their battlefield. “We are creators, so we sought the most traditional and close-minded industry out there,” they said.
