The Spirits glass is perfect for harmonizing the aroma and the taste of spirits, tempering the alcohol and the stringency of the palate and emphasizing the bouquet. The slim, flute-shaped bowl allows its contents a very small evaporation surface. This shape was one of the original 'wine friendly' glasses designed by 9th generation Claus J. RIEDEL. The generous size of this glass allows the bouquet to develop fully, and smooths out the rough edges. It emphasizes the fruit, playing down the bitter qualities of the tannin, and allows wines to achieve balance. 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 its 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.
