Wine-sniffing rodents distinguish between Riesling and Sauvignon Blanc varieties
In a groundbreaking study, researchers from London, Lincoln, Trento, and Vienna set out to determine if rats could distinguish between the aromatic profiles of two popular wine varieties: Sauvignon Blanc and Riesling. The study involved nine rats, four of which were trained to distinguish between the two types of wine.
The rats were trained to associate a particular aromatic profile with a reward and to respond by poking a lever. During the training phase, the rats nose-poked the correct lever 94% of the time on wines they had been trained on. This impressive accuracy demonstrated the rats' ability to learn and remember the distinct aromas of the wines.
When it was time for the testing phase, the rats were presented with both familiar and new wines. The rats were able to correctly identify wines 80% of the time for three consecutive sessions. Moreover, they were able to correctly identify some of the new wines, demonstrating their ability to generalize their learning.
The study results indicate that nonhuman mammals can discriminate between complex odour categories, challenging the negative perception of rats and suggesting their potential for a career change in the wine industry. However, it's important to note that there is no confirmed scientific study demonstrating that rats have wine tasting abilities in the sense of consciously tasting and distinguishing wines as humans do.
Despite this, the study suggests that rats could potentially work in the restaurant industry as elite sommeliers or even in the wine industry for quality control. With their high level of olfactory ability, matching or exceeding that of humans, rats could prove to be valuable assets in the world of wine.
As the study continues, we look forward to seeing how rats' olfactory abilities can be harnessed to benefit the wine industry. While they may not be able to read wine tasting notes or appreciate the nuances of a fine Bordeaux, their sense of smell could play a crucial role in ensuring the quality and consistency of wines.

- In the future, the advanced olfactory capabilities of rats could be utilized in the health-and-wellness sector, such as for detecting certain compounds in wine that contribute to its health benefits, like antioxidants and aromatic contents.
- Meanwhile, in the realm of technology, researchers could explore the potential of training rats to enhance wine investment strategies by teaching them to differentiate between high-quality, aged wines and those with lower market value, based on the distinct aromatic profiles of various wine varieties.
