The Aero Grand Vini 20 oz. Crystal Red Wine Glass is made in Italy of SON.hyx break resistant glass. Luigi Bormioli’s proprietary SON.hyx glassware formula represents an exciting fusion of elegance and technology. These machine blown glasses have laser cut rims, ideal weight and maintain their clarity for up to 4,000 industrial dishwashing cycles. The beautifully drawn stems have been permanently reinforced with Titanium via nanotechnologies. The Aero collection is designed with a swirling feature called the helical incision that is made to the inside of the bowl. This feature facilitates a flowing stream of bubbles resulting in an enjoyable optical effect that enhances the content.
