Since this time, the brands Riedel, Nachtmann und Spiegelau have been sold under the corporate name „Riedel Glass Works“, one of the major manufacturers of high quality glasses in Europe. The philosophy of this traditional company is that the volume should dictate the form of the glass, to subordinate the design to the wine / drink with its characteristics. Wine and the wine pressing criteria will define the design of the glass. An important criterion of quality is the very thin glasses and, however, its high stability. Depending on the thickness, the temperature of the glass will influence the temperature of the wine – the thinner the glass the less influence.
