Riedel's most classic and exclusive product line is called Sommeliers. The series was launched in 1973 and was the world's first grape-specific wineglass series ever made. Riedel created Sommeliers with the intention of enhancing aromas and flavors of specific grapes which have never been done before. The Sommeliers series has won several awards for its design. The family Sommeliers is created by 26 unique glasses. All mouth blown and available in water, spirits and wine glasses in crystal. All the glasses are dishwasher safe.
