Miller Harris is a good example of "barnyard" scent via "dirty musks" and animalic notes. Bread note : Due to 2-Acetyl-1-pyrroline (this is present in pandanus ) and to lesser degree 6-Acetyl-2,3,4,5-tetrahydropyridine. Cabbage note : Due to Methanethiol (also known as methyl mercaptan ). Naturally occuring in nuts and cheese. Cardboard/Old
