The innovative machine-made Fizz glass of the functional glass collection Drink Specific Glassware provides the perfect conditions for the pillow-shaped head of cocktails like the Gin Sour thanks to its parallel sides. The RIEDEL BARWARE DRINK SPECIFIC GLASSWARE is made in collaboration with spirits specialist Zane Harris, answering the need for cocktail-specific glassware among restaurants and bars, and for cocktail enthusiasts at home with six glasses perfected for thousands of cocktails. The glasses are based on the traditional serves for seven classic cocktails: The Old Fashioned, Manhattan, Daiquiri, Sour, Peasant, Buck and Julep. Working in partnership with Riedel, Harris created each glass giving specific attention to its size, shape, volume and capacity for ice, a concept in its totality never before explored by any glassware company. Ice has the greatest influence in glassware design as it is in practically every drink, not just the cocktail, notes Harris. RIEDEL BAR DRINK SPECIFIC GLASSWARE ice glasses are designed to seamlessly answer two of hospitalitys greatest frustrations liquid displacement and the distorted consumer perception of being underserved. Each unique glass in the RIEDEL BAR DRINK SPECIFIC GLASSWARE collection is crafted in Riedels family owned factories. All RIEDEL glasses are dishwasher safe.
