Vision Glassware. Mouth-blown fine glasses that combine visual appeal with innovative flavor functionality. Zieher from Himmelkron in Upper Franconia draws on the knowledge of numerous glass designers as well as sommeliers and top chefs. The simultaneously recessed and raised base of this glassware gives each drink its own dynamic when pouring and swirling, allowing for optimal aeration and aroma development. Deliberately, there is no strict classification for classic red and white wine glasses; instead, Zieher leaves it up to each individual to decide according to their own taste. Vision Straight Wine Glass in a set of 2. Pure and unadulterated, the Straight Wine Glass authentically captures the aroma of red and white wines—important for the fine bouquet of varietal wines such as Riesling or Sauvignon Blanc. Even light, aromatic red wines become a true pleasure to drink in this slender shape.
