What is this blue wine?
It was launched in France last year by a company called Vindigo, based in the south east city Sète. Blue wines had previously been on sale in Spain and Vindigo is joined in the French market by Corsica-based company Imajyne.
It's made in the same way as any other wine, but gets its blue colour as a result of being filtered through red grape skins which contain anthocyanins.
