A new kind of wine from Spain hit the shelves in 2016, but it was certainly not your typical Rioja.

You can spot Gik wine from a mile away. Why? Because of its beautiful bright blue colour. Proudly described by its creator as “revolutionising the world of wine with a blasphemous drink,” this blue wine was a big success, with sales of 100,000 bottles in 25 countries, according to Forbes.

However, the revolution now faces a pair of mighty foes. Following an anonymous complaint to the Spain and the European Union, inspectors forced the company to stop producing, pending an investigation.

The crime? There exists no ‘blue wine’ category under the 17 wine products listed under E.U. law!

Gik wine is made from a mix of Spanish red and white grapes and has a strength of 11.5%.  The wine gets its colour from a combination of  “anthocyanin” – a pigment found in grape skin, and “indigotine” –  a plant-based food dye.

Taste tests done by the company show that Spaniards can’t seem to tell the difference between Gik’s offer and “regularly-colored” wine. However, Gik is no longer authorized to call its beverage “wine,” and the bottle labelling is now required to call Gik “99% wine and 1% grape juice,” and marketed under “other alcoholic beverages.”

“There’s no revolution without a counter-revolution,” the company’s five young Spanish founders have said in a statement.

They’re still fighting. And they still selling their “wine,” though at the time of writing Gik is out of stock in the U.K., (although it’s currently available for pre-order in the U.S.). Whether that’s a result of demand or the E.U. regulation slam is uncertain.

The thing is, there won’t be a change in E.U. beverage law any time soon to accommodate a “blue wine” category, so the company now advertises a “blue drink” on its website and advises visitors to “forget everything you know about wine.”
