Schott Zwiesel Congresso Champagne Flute 6-pack

The Congresso Champagne Flute has a bowl shape that makes this glass highly flexible for serving NV or Vintage Sparkling wines or Champagne.
 
What makes Schott Zwiesel glasses truly unique is their perfect form and radiant gleam. Every glass is made from the patented Tritan (R) crystal glassware, which is brilliant, shatter-resistant and dishwasher safe (>2000 dishwasher cycles with no visible signs of wear).
 
It also has an outstanding ecological profile and carbon footprint (Certified ISO 14001:2004 environmental performance and ISO 14040:2009 ecological profile) and is lead and barium free.
