Zafferano Esperienze Set 6 Tumbler Glasses In Crystal Glass. The Tumbler is a type of glass with a cylindrical shape, slightly flared, with the walls of almost uniform thickness slightly thicker towards the bottom. A collection suitable for a stylish Mise en place with a suggestive aesthetic impact. Particularly suitable for white wines and water, the set was born from an intuition of Federico de Majo: to offer the wine a larger contact surface to promote oxygenation. The undulations at the base of the glass facilitate centrifugation, oxygenation and the evolutionary path of the wine, until it reaches the condition of perfect drinkability. The Experience Tumbler, whose patent is pending, is made of superior sound glass and combines a sophisticated aesthetic taste with technical content. The high quality of this material guarantees maximum transparency, high flexibility, high resistance to breakage and washing.
