The Norlan Whisky Glass is a transparent double walled vessel, formed with glass blowing technique into two separate two-part moulds: one for the inner wall, and one for the outer wall.
Through specially developed protrusion forms inside the glass, when swirled around the glass the fluid forms a standing wave shape, which increases the surface to air ratio and rate of oxidization. The effect here is that considerably more ethanol evaporates. This resulting increase in volatility allows the whisky to become significantly more expressive. This feature is an invention of the Norlan glass — no other whisky glass will do this for you.
The second main performance feature is the shape of the inner walls, which close as they rise and then flare out again so as not to hit the nose. The height and diameter of the smallest aperture focuses the aromatics to the nose while simultaneously diffusing the ethanol away from the face, fantastically improving the taste of your whisky.
