The Riedel O Wine Tumbler Cabernet / Merlot Glasses are specifically designed for full-bodied, complex red wines high in tannin. This innovative stemless design combines functional benefits with practical durability.

Made from clear crystal glass, this generously sized tumbler provides ample space for the wine's bouquet to develop fully. The carefully engineered shape works to emphasise fruit notes while simultaneously smoothing out the rough edges and playing down the bitter qualities of tannin, helping wines achieve proper balance on the palate.

Introduced in 2004, this glass made history as the first varietal-specific wine tumbler, based on the benchmark shapes of Riedel's acclaimed Vinum series. The stemless design offers a contemporary alternative to traditional stemware while maintaining the same attention to how shape influences taste.

For wine enthusiasts who appreciate both function and practicality, these machine-made tumblers fit easily into dishwashers, eliminating concerns about broken stems. The O Wine Tumbler delivers the sophisticated tasting experience Riedel is known for in a casual, versatile format suitable for everyday enjoyment of premium red wines.
