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. Ideal for lighter bodies red such as Burgundy or Beaujolais; the bulbous shape of the glass allows for greater aromatics and fruit in the wine.
