This style of glass plays several roles. It works as a water glass and also holds beer for those meals when you want a little something nicer to sip your favorite ale. The Diva Tritan by Schott Zwiesel is a breakthrough in crystal glass! After years of extensive research, Schott Zwiesel has revolutionized the wine glass with an incredibly pure, hard and clear crystal glass that's highly resistant to chipping and breaking even at its most sensitive areas - the rim and at the points where the stem joins the bowl and the foot. The glasses stand up to daily use and thousands of cycles in your dishwasher, without any blemishes or loss of brilliance.
