This set contains of 4 pieces RIEDEL Performance: Cabernet/Merlot, Sauvignon Blanc, Pinot Noir and Chardonnay. The shape of the Cabernet/Merlot glass showcases the majestically structured red wines in all their complexity and finesse. The shape of the Sauvignon Blanc glass shows the combination of fruit and acidity perfectly balanced on the palate, giving a harmonious taste experience. The shape of the Pinot Noir bowl supports peatiness flavor and the taste of plum of these sensual red wines. The size of the Chardonnay bowl allows space for the rich bouquet to develop its superbly diverse range of aromas, while minimizing the risk of becoming over concentrated. Performance is the first RIEDEL wine glass series ever to feature bowls with a light optic impact, which not only adds a pleasing visual aspect to the bowl, but also increases the inner surface area. All RIEDEL glasses are dishwasher safe.
