The Story of RiedelFew glass makers can claim a history dating to the 17th century. But that's when Johann Christoph Riedel began in Bohemia what would become a renowned story of glass enterprise. Modern-day Riedel continues a generations-long history of fine glassmaking, with Claus Riedel innovating the technique of designing a wineglass shape according to the character of the wine. This revolutionary technique has changed the face of wineglass making the world over. Riedel embraces a holistic pleasure of life, including all five senses. They are committed to creating a pleasurable zest for life out of every glass object they make. Riedel is unmatched in the world of glass.
