Adhering to the Riedel principle of content commands shape, these Vinum wine glasses highlight the rich fruit while tempering the high acidity of full-bodied reds. High-quality crystal makes the set as beautiful as it is functional, perfect for any table and occasion. The launch of the machine-made Vinum glass collection by Riedel Glass fundamentally changed the drinking glass culture. It later became the first varietal-specific machine-made glass in history!
