The Riedel O Wine Tumbler Stemless Champagne Glasses feature a redesigned, more elegant shape that maintains the functional benefits of its predecessor. This innovative stemless design continues the benchmark shapes of the Vinum series—without the traditional stem or base.

Made from clear crystal glass, this specialised tumbler offers significant advantages over conventional flutes. Its egg-shaped design allows complex aromatic layers to develop and intensify properly, while the larger rim diameter enables these aromas to be released in a way narrow glasses cannot achieve. The glass includes an integrated "sparkling point" to aid in bubble formation and persistence.

For optimal enjoyment, Riedel recommends filling the glass only one-third full to ensure champagne and sparkling wine aromas are properly evident. The thoughtfully engineered shape is particularly effective with light, fresh, dry champagnes, Proseccos, and other sparkling wines.

Introduced in 2004 as part of the first varietal-specific wine tumbler collection, these machine-made glasses combine sophisticated design with practical functionality. They're comfortable to hold, dishwasher safe, and eliminate concerns about broken stems—making them ideal for both special occasions and everyday enjoyment of fine sparkling wines.
