Georg Riedel created the Vinum series as an accessible range of varietal specific wine glasses. The Riedel site says, "This glass allows the wide range of aromatics to unfold. Unlike a flute, the egg-shaped design allows the complex layers to grow and intensify, and the larger rim diameter enables them to be released in a way which is not achieved with a narrow glass. The glass also includes a 'sparkling point' to aid the formation of the Champagne bubbles."
