Open Up Open Up Premium Wine GlassesChef & Sommelier have been pioneers in the glassware department by using a new type of glass for their products. The Chef and Sommelier Open Up wine glass has an iconic bevelled top that magnificently demonstrates the benefits and ingenious of technical glassware design. This range is made from Kwarx glass. Kwarx glasses seem to vanish, which enables the guest to fully enjoy their drink, with almost nothing between them and the wine. Also, they have a never-ending sparkle. Extraordinary brilliance that has been tested time and time again in the lab shows that Kwarx glass can withstand even the most rigorous of hospitality conditions, and still maintain its impressive shine.Kwarx glass is incredibly impact resistant and maintains its extreme shine, even after 2000 industrial wash cycles. The products are also incredibly solid, thanks to the invisible but very strong bond between the bases, stems and bowls of the glasses. This means there is not a single weak point in the glass, reducing the risk of breakage. The glasses are also dishwasher safe, a bonus for busy venues that would see frequent use of the products.
