The original stemless wineglass, the "O" collection is the ideal glass for everyday use, for any drink, and for every occasion. In designing the "O" series Maximilian Riedel has created something completely new, without losing sight of his roots in the process. He said, "although the enjoyment of wine is of course at the forefront when making a Riedel glass, the special thing about this series is that the glasses are also perfectly suited to all other drinks."
