SOMMELIERS (1973): with the introduction of the Sommeliers line, Riedel gained worldwide recognition. A glass wine was born,it was a friend of wine: designed to support and enhance all the goodness of a specific variety of grapes with which that wine was made. They are made of lead crystal, with manual processing and mouth blowing in Austria.

O (2004) is the first specific varietal line of wine tumblers. “O” is based on the forms of the Vinum line, so as to enhance the qualities of the most important varietal wine groups in the world. The tumbler, used for centuries as an undifferentiated glass, has now become a sophisticated 'technical' tool for tasting. It is machine made in Bavaria, Germany, in lead-free top quality glass.
