 Alright, colour me interested, how does scientists' study smell? Like, is there a robot nose? Actually, yes! Chemists will often use really advanced instruments that can scan a substance and then identify all the volatile compounds within it. I stumbled across this one bit of research that I doubt anyone has heard of. A recent study analysed heather honey. So that means that the bees should only have been sourcing their nectars from heather.
