The Riedel Sommelier Sauternes glass was originally developed in 1989 in collaboration with Hardy Rodenstock, described by the Wine Spectator as "the world's most extravagant wine collector".
It was first issued as a glass for dry white wine as part of Riedel's mouth-blown HR1 collection.
Ironically enough, tastings around the world have subsequently shown it to be the ideal glass for Sauternes and sweet wines.
The unusual curved design accentuates the apricot aromas typical of wines made from grapes affected by botrytis ('noble rot').
The mouth blown, lead crystal glass is designed to emphasise acidity, thus balancing the wine's liquorous sweetness and luscious finish.
