I have opened Heitz Cellar Wine which was Carbernet sauvignon at Napa Valley in 2005. Today I purchased new Wine glass as well. This Large type of wine glass is named Schott Zwiesel
which is developed in collaboration with the University of Erlangen in Germany. It's not only a beautiful but also has a strength. Schott Zwiesel said you could use this glass every day. It's also acceptable a washing machine!
