In the Summer of 2018, Georg was asked by a customer to create "the ultimate glass" for Cabernet Sauvignon, a project which was to provide the inspiration behind RIEDEL Winewings. Slowly, a new shape emerged: A flat-bottomed glass, wide and reminiscent of the wing of an aircraft, complete with winglets. Over the course of a year, through many tastings and by making changes to shape, size and rim diameter, what began as one glass for one grape varietal developed into seven different glasses to represent the most popular grape varietals.
