The distinct bowl shape directs the wine to a specific area on the palate, so each note can be appreciated and savored. Both simple, yet elegant, these stems complement any dinnerware pattern. This Riedel Sauvignon Blanc glass is recommended for drinking Sauvignon blanc, Semillion, Chenin Blanc, Fume Blanc; essentially, lighter white wines. Introduced in 1986, the Vinum collection is based exclusively on the characteristics of grape varietals, meaning the content commands the shape.
