The unadorned handmade Burgundy Grand Cru glass of the beautiful glass collection sommeliers distinguishes by an impeccable quality. The larger bowl allows the bouquet to develop to the full, while slightly flared top lip maximizes the fruit flavors by directing a precise flow onto the front palate. The sommeliers series is the world's first grape varietal specific wine glass and turns every Sip into a celebration. All Riedel glasses are dishwasher safe.
