The glass is perfect for balancing the high acidity and residual sugar of fruit-forward white and red wines. This shape is the most versatile white wine glass in the Riedel range, however, it also works perfectly well for a few red wines, like Zinfandel. It helps to balance the fresh characters and high mineral components, emphasizing the wonderful fruit aromas. 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 Sommeliers range, machine production means Vinum can be offered at a more accessible price. Machine-made dishwashers are safe.
