Chef & Sommelier's Reveal 'Up flutes are specifically designed for tasting sparkling wines, but will also enhance any carbonated beverage. Thanks to the addition of Effervescence Plus, your beverages stay bubbly for longer, maintaining a fresher and more premium appearance. But functionality doesn't stop there. These Reveal 'Up flutes feature a very thin rim for a smooth transition from glass to mouth, enhancing your tasting experience. Crafted from Kwarx Advanced Glass, they're exceptionally durable and maintain their brilliant shine - even after 2,000 dishwasher cycles.
