Sommeliers was the world’s first wine glass collection and a design revolution created by Claus J. Riedel (9th generation). The range adheres to the Bauhaus design principle that form follows function, as Claus J. Riedel discovered that certain wines showed more depth and balance when enjoyed in certain shapes. Finely blown and unadorned, Sommeliers marked the beginning of RIEDEL’s dominance of the global wine glass market.
