The Bottega del Vino Crystal Whisky Tumbler was designed by noted Scotch Whisky authority, David Johnson. A beautiful crystal Scotch Tumbler, Johnson's Whisky Tot offers two hand cut measuring lines to ensure the perfect serving. The lower line is cut at 1-Ounce to measure the traditional wee dram of Scottish ancestry while the upper line is cut at 5-Ounce, the traditional gill. Beautiful, lead-free Bottega del Vino crystal from Verona, Italy is mouth-blown and hand-finished to create light, perfectly balanced, elegant shapes. Astonishingly, this crystal is not fragile! The master sommelier at Bottega del Vino designed the stemware to replace lead oxide with lighter barium oxide, which is clearer, more brilliant, and much less fragile than lead crystal. In fact, these glasses are dishwasher safe and used in restaurants worldwide. The superbly crafted bowl and single pull stem feel marvelous in your hand and on your lips, and intensify the pleasure of drinking fine wines. Bottega del Vino is dedicated to creating the finest possible wine glass from which to savor and appreciate the result of years of work in the vineyard. Their lead-free crystal is produced by hand using centuries-old techniques and skills that are mastered with years of experience. Satisfaction guaranteed or your money back. Dishwasher safe.
