Ouverture from Riedel is a good start and entrance to Riedel's range. Ouverture has glasses for everyday use and parties. Perfect for those who appreciate good design at a good price. What distinguishes Ouverture from other glasses from Riedel's range is that Ouverture is not grape-specific, but the design still enhances the experience and flavors. Ouverture consists of eight different waters, spirits and wine glasses in crystal and all glasses can be machine washed.
