Schott Zwiesel Bar Collection Whiskey Tumblers

World-renowned bartender and author of American Bar, Charles Schumann and German glassmaker Schott Zwiesel bring you the ultimate collection for the bar. Each piece is brilliantly clear, lead-free Tritan crystal, break-resistant and dishwasher safe. The design follows the ambition that each glass underlines the specific character of its respective drink. The 12-oz. whiskey tumbler is subtly tapered with a thick base—a time-tested shape perfect for an old fashioned or whiskey rocks.

The secret to Schott Zwiesel glassware’s longevity is their exclusive Tritan crystal and manufacturing technology. By eliminating lead content from glass and replacing it with titanium and zirconium, Tritan crystal delivers superior durability and brilliant light-reflecting appearance. Additionally, Schott Zwiesel reinforces the zones on their glassware most vulnerable to breakage: the rim, the junction of bowl and stem, and the junction of foot and stem. Independent testing has proven Schott Zwiesel glassware resists chips, scratches, breakage, discoloration, spots and stains even after 1,000 cycles in the dishwasher, helping it maintain its beauty and luster for a lifetime of use.
