The Bordeaux Grand Cru XL glass is perfect for full-bodied, complex red wines that are high in tannin. The shape of the Bordeaux glas was one of the original „wine friendly“ glasses designed by 9th generation Cluas J. RIEDEL. The generous size of this glass allows the bouquet to develop fully, and smooths out the rough edges. It emphasises the fruit, playing down the bitter qualities of the tannin, and allows wines to achieve balance.
