Whisky Glass by Norlan

The Norlan Whisky glass is a transparent double walled vessel, formed with glass blowing technique into two separate two-part molds: one for the inner wall, and one for the outer wall. When the inner and outer glass walls are prepared, the rims are reheated and the inner glass is inserted, at which time the rims are sealed. This creates a hollow body glass with dramatically different inside shape to outside shape.

A unique effect of the double-walled construction is the intensity of color added to spirits in the bowl, which is further carried up into the rim of the glass.

Through specially developed protrusion forms inside the glass, based on bio-mimicry, 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 reduction in volatility allows the whisky to become significantly more expressive.

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.
