Byredo's Oud Immortelis in our database, but we haven't aggregated enough community evidence to score any dupes for it yet. The Scent File Method requires consensus across Reddit, Fragrantica, and blind-test threads — popular dupes for this fragrance get added as that evidence accumulates.
In the meantime, browse the rest of the database or read about how we score dupes.
Every dupe is rated on two independent dimensions: scent accuracy (how closely it matches the original) and longevity (how long it lasts on skin). Scores are aggregated from community consensus on Reddit r/fragrance, r/fragranceclones, and Fragrantica. They are never averaged into a single number — accuracy and longevity are separate decisions.
No. The Scent File takes no brand deals, no sponsorships, and no paid rankings. Rankings reflect community consensus only. We do earn affiliate commission when you purchase through our links at no extra cost to you — but this never influences which dupes appear or how they are scored.
New matches, reformulation alerts, honest scores. No spam.
