The diamond-shaped machine-made Shiraz glass of the eye-catching glass collection Extreme is focused on New World Wines. The shape of the glass optimal delivers the classic aromas of toast and black olives, which are typical for wines made of Shiraz grapes. On the palate, it brings out the wine's silky, velvety structure and balanced flavours. The tannins melt into the fruit, appearing sweet rather than acerbic on the back palate. The Extreme glasses derive their name from their extreme contours. All RIEDEL glasses are dishwasher safe.
