A glass shape like ONEforYou can't think of ALL - it has to be developed! This process took more than two years. In over 80 tasting rounds, the evolution and finally the final glass emerged from a basic pattern. Hundreds of wines were tasted again and again - from the glass that had been further developed in each case. Many sommeliers and winemakers contributed to an objective result. The glass is bulbous in the lower part so that the wine gets as much oxygen as possible over a large surface to release its aromas. The narrow opening concentrates the aromas and automatically brings the drink to the middle of the tongue so that it is optimally distributed in the mouth. Both sizes are ideal for enjoying all white, red, rosé, sparkling and sweet wines, all grape varieties, origins and ages as well as clear and barrel-aged spirits. I recommend the small glass as a professional tasting glass and preferably for champagne, sparkling wine, white, rosé, sparkling and sweet wines, sherry, port and high-quality spirits. The larger one is an excellent glass for enjoyment and particularly supports the development of aromas in red wines, great white wines and special sparkling wines and champagne.
