The Cabernet glass is perfect for full-bodied, complex red wines that are high in tannin. The generous size of this glass allows the bouquet to develop fully and smooths out the rough edges. It emphasizes the fruit, playing down the bitter qualities of the tannin, and allows wines to achieve balance. Vinum is RIEDEL's basic varietal-specific stemmed series. Designed in 1986 by 10th-generation glassmaker Georg J. Riedel, Vinum was created to ensure every wine lover could afford varietal-specific glassware. Based on the handmade Sommelier's range, machine production means Vinum can be offered at a more accessible price. Machine-made dishwashers are safe.
