As they say themselves over at Norlan Glass:

“The Norlan Whisky Glass has been developed through a process of combining fluid dynamics modeling and bio-mimicry, out of a love for whisky matched with a frustration by the poor glassware available to whisky enthusiasts.

By marrying a scientifically performing inside with an aesthetically beautiful outside, our glass is designed to capture whisky’s complex perfumes and deliver them to the senses better than any existing product.”
