A glass shape like ONE for ALL can't simply be invented – it has to be developed! This process took more than two years. Over 80 tasting sessions evolved from a basic design to the final glass. Hundreds of wines were repeatedly tasted from the latest iterations of the glass. Numerous sommeliers and winemakers contributed to an objective result. The glass is bulbous at the bottom to maximize the surface area of ​​the wine, allowing it to receive as much oxygen as possible to release its aromas. The narrow opening concentrates the aromas and automatically directs the drink to the center of the tongue, ensuring optimal distribution in the mouth. Both sizes are excellent for enjoying all white, red, rosé, sparkling, and sweet wines, regardless of grape variety, origin, or age, as well as clear and barrel-aged spirits. I recommend the smaller glass as a professional tasting glass and especially for Champagne, sparkling wine, white, rosé, and sweet wines, Sherry, Port, and premium spirits. The larger one is an excellent glass for enjoying wine and particularly supports the development of aromas in red wines, great white wines and special sparkling wines and champagnes.
