The Riedel O Cabernet/Merlot Tumbler is a stemless wine glass designed for bold, complex red wines with high tannin content. The bouquet can beautifully express itself through the wide surface of the bowl, while bitter tannins are softened, creating a pleasing balance.

With the Riedel O wine tumblers, broken stems are a thing of the past. The collection was designed in 2004 and includes the first stemless, varietal-specific wine glasses in glass history. They are handy, fit into any shelf, and can even be taken to outdoor BBQs.

The set consists of 2 glasses.
