The handy machine-made Syrah and Shiraz glass of the space-saving glass collection O Wine Tumbler attracts attention through its stemless design. This makes it less susceptible to glass breakage and easy to put into the dishwasher. It is shaped to deliver the classic Syrah aromas of toast and black olives. On the palate, it brings out the wine's silky, velvety structure and balanced flavors. The tannins melt into the fruit, appearing sweet rather than acerbic on the back palate. "O" is the ideal glass for everyday use and for every occasion. It is fun, feels good to hold, looks trendy and it works! All RIEDEL glasses are dishwasher safe.
