I have been a prime member for many years, but this is the first time I have written a review. Being a scotch drinker I bought these.
Cons: No weight to the glass, very fragile, shape is odd/non traditional and I prefer the look of glancairn glasses (personal preference)
Pros: Does what it says in eliminating some of the harsh alcohol vapor, biggest difference (understandably) noticed in cask strength whiskey
Testing: I had my 58 year old mother who does not drink whiskey smell a ardbeg and a glendronach in the norlan glass and a glencairn glass. Without knowing the purpose of the test of the test she immediately told me the norlan glasses smelled smoother, less caustic and less like rubbing alcohol.
Overall I think if you drink scotch a few times a week and can afford to spend 40$ or more on a bottle, you should pick these glasses up. I have a small reservation that these might subdue some of the scent/flavor while subduing the ethos vapors that glencairn glasses would otherwise let you pick up. I continue to drink scotch side by side in the two glasses ( Norlan and glencairn) and I seem to be able to find all the components of the nose in both glasses. I gave four stars for the lack of weight to the glass and the fragility. I hope they make a second generation glass with a little more weight.
Inspired by nature, digitally crafted, and refined with master distiller Jim McEwan, the Norlan Whisky Glass has been designed to capture whisky's complex flavors and aromatics and deliver them to the senses like never before. The featherweight double-walled structure offers a seamless integration of a scientifically performing inside with an aesthetically beautiful outside, for the perfect whisky drinking experience. Aeration Through specially developed protrusion forms inside the glass - adapted through studying 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 allowing 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. Aroma Focus 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. Form and Construction The Norlan 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. The Norlan Glass was designed with the intention of enjoying whisky neat. Should you decide to use ice, please be mindful that cubes must be gently placed into the inner bowl. Use of whisky stones is prohibited.
