The RIEDEL O Wine Tumbler – Pinot Noir/Nebbiolo Glass is a stemless crystal glass designed specifically for light-bodied red wines with high acidity and moderate tannins. Its balloon-shaped bowl captures and concentrates the wine’s aroma, highlighting rich, fruit-forward flavors while balancing acidity for a smooth, nuanced tasting experience. Part of RIEDEL’s O Wine Tumbler series—the first varietal-specific stemless wine glasses introduced in 2004—this machine-made glass combines elegance with everyday practicality. Made from clear crystal, it is dishwasher safe, offering a durable, casual alternative to traditional stemware without sacrificing the wine’s full aromatic expression.
