@Wusubi that makes sense, I can picture what you're saying - the rind definitely produces natural oils too, so I guess I get that as well at times with various citruses!
@Gourmandgrl when bergamot is super tangy and realistic, it reminds me of an essential oil, thus almost oily in texture. I would use the same word for guerlinade or Bergamask.
Makes perfect sense when the scent manages to capture the rind too, not just the juice.
