The Perfect Serve 26.5 oz. Highball Glass belongs to the perfect serve glass series by Spiegelau and has the perfect height and exactly the right capacity for typical cocktails and highballs. Thanks to the slightly rounded inside of the glass, carbonated drinks stay fresh for a longer time and the carbonic acid doesn't break. In addition, the height of the glass is ideal to precool it in a standard freezer before preparing the drink.
