This Is Whiskey-Scented Fabric

Harris Tweed is a renowned fabric made in the Outer Hebrides of Scotland. Johnnie Walker Scotch whiskey is, similarly, a famous product of Scotland. The companies that produce both are coming together to produce a combined product: tweed that smells like Johnnie Walker.
Researchers at Heriot Watt University developed a process to infuse the fabric with the whiskey smell in such a way that it will continue to smell even after it's cleaned. BBC News reports:

The scent called Aqua Alba has been designed to replicate aromas released from a glass of whiskey, known as the nose of the liquid.
According to Johnnie Walker, the cloth smells of "rich malt, golden vanilla, red fruit and dark chocolate tones". […]
Donald Mackay, who heads the finishing department at the mill, said: "I have worked with aromas in the past but they were only meant to withstand one dry clean.
"The process we have devised for Johnnie Walker means that this scent is layered into the fabric throughout the finishing process and is permanently imbued in the tweed."
