I know this is a cliche topic, but I have noticed the amount of honey in different New York Ouds varies. The honey is what gives New York Oud, a very animalic sweaty drydown. Some bottles have a very thick heavy drydown, while in some bottles the animalic drydown is quite light. Have any others noticed this?
Honey is a very interesting substance. The honey that bees make after pollinating different flowers has different properties. While I don't know about Oud batch variations, this could be part of it.
The fabled musk deer searches the world over for the source of the scent which comes from itself.
