I think if I didn't know what I was looking for, I would have missed a few of the flavours last night.
In order of ease of detection for me would be
Soil
Green apples
Cooked corn
Acetic
Marzipan
Baby vomit
Diacetyl (which didn't smell/taste especially buttery to me, but did taste different from the control Heino)
Sewer (which I didn't really detect at all)
It was interesting how much variety there seemed to be between tasters.
