Zieher's Vision Fresh is the glass for those who keep healthy white wines, sparkling wines and light rosé close to the heart. The opening of the cup is designed to allow the carbon dioxide from sparkling wines to evaporate gently in the best way, and thus not ruin the aroma experience. All glasses from the Vision series are hand-blown in crystal glass by Zieher's incredibly skilled craftsmen. The glass is dishwasher safe.
