This burgundy glass is for the true wine lovers. The design is more than just beautiful. It also enhances the fullness of the wine's flavor, allowing the wine aromas to come through even more. The glasses are made from TeQton glass. This type of glass is crystal clear, break-resistant, and of course, dishwasher safe. Another advantage is that the glasses come in a set of 6. This is naturally very convenient if you need multiple glasses for a special occasion.
