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.
Stemless Design: The absence of a stem makes the glass practical for everyday use, easy to store and less susceptible to broken stems. The O tumbler is also stackable and fits into standard dishwashers.
Value Pack: The 5415/85 format contains eight glasses in a value-pack configuration, supplied as a Pay 6, Get 8 set.
