Features
Signature Shape: The O Wine Tumbler is Riedel's pioneering stemless varietal-specific wine glass, introduced in 2004 and based on the benchmark shapes of the Vinum collection.
Viognier & Chardonnay Focus: The bowl is designed for white wines such as Viognier and Chardonnay, helping express freshness, spice and mineral character while supporting a rich, supple texture.
Aromatic Performance: The shape is particularly suited to Viognier's naturally lower acidity, helping balance its alcohol and rich fruit while emphasising its velvety texture and supporting a long, balanced finish.
