AI learns to distinguish between aromas of US and Scottish whiskies

One algorithm identified the five strongest notes in each drink more accurately than any one of a panel of experts

Notch up another win for artificial intelligence. Researchers have used the technology to predict the notes that waft off whisky and determine whether a dram was made in the US or Scotland.

The work is a step towards automated systems that can predict the complex aroma of whisky from its molecular makeup. Expert panels usually assess woody, smoky, buttery or caramel aromas, which can help to ensure they don’t vary substantially between batches of the same product.
