The Norlan Steel Tumbler has been developed for the whisky and fine spirit enthusiast who accepts no compromise where travel and tasting are concerned. And for those staying close to home, we have created an extraordinary, luxurious vessel for your intimate whisky ritual (ice, for those who choose, now allowed).Under consideration for development for many years, the design of the tumbler mirrors that of our original double-walled glass with some key differences. Instead of mouth-blown borosilicate glass, the tumbler is produced from blow-molded stainless steel. The join at the mouth rim, where the inner and outer walls are held together, is made by electro welding, creating a fine point of contact for the lips. Inside, the tumbler is finished with a food-grade safe electroplated coating that acts as a mirror for the contents within. On the outside, the tumblers are exhaustively hand-burnished before receiving their final finish in polished stainless steel or mirror black PVD coating.Being a fraternal twin, the new tumbler of course shares much of the design genetics of the original Norlan Whisky Glass. You will find the same inner and outer shapes, merging a highly functional nosing glass interior with a modern exterior. Which means the tumbler will serve to elevate your favorite whisk(e)y—whether Scotch, Bourbon, Rye, Canadian, Japanese, you name it—and look mighty stellar while doing so. Additionally, being made out of steel, the new tumbler has the added benefit of mobility. Wrap the tumbler in a cloth of your choosing, throw it in your bag, and you have the ideal nosing and drinking vessel for wherever your journeys may take you.
