This Riedel Sommeliers Bordeaux Grand Cru glass, first created in 1959, is not a design gimmick but a precision instrument, developed to highlight the unique characteristics of the great wines of Bordeaux.

Mouth blown from lead-free crystal, the large bowl (capacity 860cc) brings out the full depth of contemporary wines made from Cabernet Sauvignon, Cabernet Franc and Merlot.

Modern vinification techniques enable wine-makers to concentrate the fruit to such an extent that young wines may seem one-dimensional, tannic and over-oaked if served in smaller glasses.

The Riedel Sommeliers Bordeaux Grand Cru glass gives breathing space to both young and more mature wines, unpacking the various layers of bouquet and delivering a full spectrum of aromas.

On the palate, the texture of the wine - soft, silky, velvety - is intensified and the finish prolonged, gently blending acidity with supple, sweet tannins.

This is a glass that showcases these majestically structured red wines in all their complexity and finesse.
