Perfect for young, full-bodied (more than 12 percent alcohol), complex red wines that are high in tannin. This glass smoothes out the rough edges, emphasizing the fruit, allowing wines to achieve a balance that would normally take years of ageing to acquire. The generous size of this glass allows the bouquet to develop fully. The shape directs the flow of wine onto the zone of the tongue which perceives sweetness, thus accentuating the fruit and de-emphasizing the bitter qualities of the tannin. Recommended for: Bordeaux (red), Cabernet Franc, Cabernet Sauvignon, Merlot, Rioja, Tempranillo. All Riedel glasses are dishwasher safe.
