How to Evaluate a Fragrance Oil Like a Perfumer

Evaluating fragrance oil on blotter strips

When a sample kit arrives, the natural instinct is to open each vial and sniff. It is also the least reliable way to judge a fragrance. The bottle neck concentrates the most volatile notes, alcohol-free oils can smell harsh up close, and after four or five sniffs your nose is tired. Perfumers use a more patient method, and you can too.

What you need

  • Paper blotter strips (smelling strips), or plain unscented card cut into thin strips.
  • A pencil to label every strip.
  • A quiet, well-ventilated room without cooking or incense smells.
  • A notebook, or your phone.

The method

  1. Label first. Write the oil name on the strip before dipping. Unlabelled strips are useless within minutes.
  2. Dip lightly. Just the tip, about one centimetre. Too much oil overwhelms the strip.
  3. Wait a few seconds, then smell with the strip a few centimetres from your nose. Note the opening: what do you notice first?
  4. Smell again at 15 minutes, 1 hour and 4 hours. This is where the heart and base appear, and where quality really shows.
  5. Leave it overnight. The next morning tells you about longevity and the base notes.

Compare, do not judge in isolation

Evaluate no more than three or four oils at a time, and always side by side. If you are comparing an inspired oil with a reference perfume, dip or spray both on separate strips and smell them alternately at each stage. Most differences show in the opening; a well-matched oil often converges with the reference in the dry-down.

Rest your nose

Smell the inside of your elbow or step outside for fresh air between rounds. Coffee beans are a popular trick, but plain fresh air works just as well.

Finish on skin

Blotters show the structure; skin shows real life. Once you have a shortlist, test a diluted blend on skin over a full day before ordering in bulk.
