Back in August, during my vacation, Anya left a question to Laurent at Laurent’s video interview. You can find her question here. I’m finally posting Laurent’s answer to the question. The reason for this time lag is due to my lack of communication with the perfumers. My apology. Nobi
We perfumers definitely feel roundness and scratchiness. When we say that a fragrance is round it means nothing is sticking out, all ingredients or notes are well balanced, not even one note will take over the others. And usually a fragrance that is round smells almost the same from the start to finish.
A fragrance which is scratchy tells something is sticking out, and it is usually not pleasant, it’s almost like having something in your throat.
Going back to your question, I do not use shape as an inspiration.
