Vision Glassware. Mouth-blown fine glasses that combine visual appeal with innovative flavor functionality. Zieher from Himmelkron in Upper Franconia draws on the expertise of numerous glass designers, sommeliers, and top chefs. The simultaneously recessed and raised base of this glassware gives each drink its own dynamic when pouring and swirling, ensuring optimal aeration and flavor 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 varietally defined drops like Riesling or Sauvignon Blanc. Even light, aromatic red wines become a pure pleasure to drink in this slender form.
