The e-nose used the set of metal oxide, gas sensors, to assess t-shirts, worn by participants, one group of human smellers. Were given pairs of these shirts and asked to rate, how similar?
Some animals that are known to be great smellers, like dogs who can sniff out explosives and pigs who can find truffles underground, put their noses right at the place they want to smell.
Yeah, basically, we have words that we can use to talk about wine, you know, bouquet, mouthfeel, flavor profile, all of that, that kind of makes up for our lack of smeller genes when it comes compared to rats.
