How to Test Perfume Samples: A Comparison You Can Repeat

Keep the identity attached to the sample

Write the brand, exact fragrance name and concentration before testing. Include the size if you have different formats. A similarly named extrait or flanker should get its own entry, even when the packaging looks familiar.

Use a separate labeled blotter for each scent and keep them apart. The blotter is an introduction, not a substitute for deciding whether you enjoy wearing the fragrance. Diptyque’s own product advice recommends trying a fragrance on skin when choosing one.

Use a small set of repeatable observations

Our notebook uses an opening impression, a check around one hour, and a later observation. Those times are prompts, not a claim that every fragrance changes on the same schedule. You can add your own check when something noticeable happens.

Write simple descriptions in your own words. “Sharper than I wanted” or “I still enjoy this after lunch” tells you more than trying to identify every advertised note. Leave a blank when you cannot distinguish a note.

Compare one new fragrance at a time

Follow the product directions when testing a sample that is suitable for you. For the first comparison, avoid layering several new scents on yourself. Different application amounts, locations and settings can make it harder to know what caused a difference.

Use a second ordinary day for the strongest candidate. Record the setting and approximate application so you can compare fairly. If a scent becomes uncomfortable, stop that test; finishing a notebook row is not a reason to keep wearing it.

Give each sample a next action

Use three decisions: keep, try again or pass. “Try again” is useful when you enjoyed the opening but were distracted for the rest of the day. “Pass” can still produce a valuable note about what to avoid next time.

A complete first round does not have to produce a bottle purchase. It may narrow a family, identify a disliked effect or show that a small travel size would be enough. Let the notebook reduce the next order, rather than create an obligation to collect more.

Use a record that can change your mind

Use this comparison to make one decision at a time. The rows are our editorial prompts; they are not a product rating or a prediction of your result.

Worked example: turn the comparison into a next step

An invented notebook entry might read: “Sample A, EDT, dabber; quiet afternoon at home; opening pleasant; later sweeter than wanted; retry on another ordinary day.” Sample B was a spray worn outdoors, so “B lasted longer” is not yet a fair conclusion.

If A is still too sweet on the repeat, pass on it and carry “less sweet later” into the next brief. If the vial runs out before the comparison is useful, decide whether another sample is worth buying. A partly completed test is a valid outcome; you do not need to manufacture a rating.

When your own nose stops noticing

CHANEL describes becoming accustomed to a fragrance as olfactory habituation. A change in your own perception is not a measurement of how much fragrance remains or how someone else perceives it. Leave an uncertain observation uncertain rather than turning it into a longevity score.
