The Riedel Superleggero is a masterpiece of state-of-the-art-technology. The perfection of a premium machine-made glass compared to handmade lies in the precision of the bowl and rim diameter and ist consistent quality. The collection includes the largest, thinnest, and lightest glasses with the widest base diameter of up to 106 mm ever produced on machine to date. Premium machine-made and dishwasher safe. “PREMIUM” defines the advantage of a machine blown RIEDEL glass vs. A hand-made glass. The difference lies within the precision. Since RIEDEL glasses are fine-tuned instruments that support your wine enjoyment, we must make sure that there are no variances in the execution of the bowl and rim diameter, which is the key to our philosophy! This pack contains a single piece.
