This 9 1/2 oz Atelier Champagne Flute (08748/07) is presented by Libbey. This glass is part of the Atelier Collection and made with Luigi Bormioli crystal glass. Bormioli glass is made from the purest of raw materials, which produces glass with a high level of transparency. The bowl is designed to retain champagne's carbonation, by reducing the surface area at the opening of the bowl. This is an excellent all-purpose champagne flute and would make a great addition to any stemware collection. The recommended champagne serving temperature range is 50°-55°F.
