Our gourmet glass series makes the hearts of wine lovers and aesthetes beat faster. With the thin-walled dome of the drinking vessel, the fine stem and the wide base plate, the high-quality, machine-made series looks almost like mouth-blown. Schott Zwiesel Crystal Glass is made from a formula that replaces lead with zirconium and titanium for brilliance and strength. Schott Zwiesel Crystal Glass is unrivaled for the elegance of its design yet it is dishwasher safe.
