Beautifully designed, the Norlan Whiskey Glass Black Edition will elevate your experience of drinking your favorite whiskey. The hand-blown borosilicate glass with a matte black exterior finish conceals the outer wall, while the inner wall reveals the goodness inside. These glasses not only look amazing, they also enhance your whiskey's taste and aroma through the pure shape. The inner walls of the glass close as they rise and then flare out again and the height and diameter of the smallest aperture bring the aroma to your nose while simultaneously diffusing the ethanol away from your face. No other whiskey glass is as meticulously designed to improve the taste of your whiskey.
