The Eddy decanter is top quality. A good example craftsmanship, made of the high quality Borosilicate glass. It glass is characterized by the dense structure, unwise clarity and robustness. In addition to that the design fascinating and is advanced, the carafe takes care of unparalleled speed development of the wine. Only one few "swirls" in the Eddy goes through the wine, because of the a thousandfold swirls at the conical notches, a process whose behavior matches with an oxidation reaction of several hours, indoors a few seconds. Functionality is rare on such an enchanting way united with aesthetic design!
