Adhering to the Riedel principle of content commands shape, these Vinum wine glasses are generously sized to balance the sweet fruitiness and bitter tannins of young, complex 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!
