Researchers use a synthetic 'tongue' to sort out whiskies

Whiskies may differ in taste and smell, but they are so similar in chemical composition that most analyses can't tell two closely related brews apart. In a new article, researchers introduce an artificial sensor array or 'tongue' that can detect whether two nearly identical whisky samples are a match. The sensor arrays can also identify some of the whiskies' key qualities, such as malt status, age, and country of origin.
