The Bordeaux Grand Cru glass is perfect for full-bodied, complex red wines that are high in tannin. This shape was one of the original 'wine friendly' glasses designed by 9th generation Claus J. RIEDEL. 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.
