The Riedel Vinum Cabernet / Merlot / Bordeaux wine glass is ideal for full-bodied complex red wines that are high in alcohol and tannins. The generous size allows the wine to aerate in the glass and the bouquet to develop fully. The shape of the rim directs the flow of the wine to the front palate to enhance sweetness thus accentuating the fruit while softening bitter tannins. Recommended for Bordeaux (red) Brunello di Montalcino Sangiovese Cabernet Franc.
