The Rauk Heavy Tumbler has been developed for whisky drinkers who prefer their spirit chilled. And for those who revel in the crafted cocktail, the tumbler features a core innovation: an array of extruded chevrons radiating from the inner base serve to provide friction points for gripping ingredients used in muddled drinks. Subverting the tradition of cut crystal, the entire surface of the tumbler, inside and out, is born in a single moment of machine-pressing the molten crystal into a complex five-part mold. The precision modeled base touches down on four crystal points, giving this very heavy tumbler the appearance of floating.
