Exaltatum

Exaltatum's workshop is run by Eglija Vaitkevice, a Grasse-trained perfumer who also has her own niche line - and the second part matters as much as the first. Anyone can hire a room and lay out bottles; being taught by someone whose fragrances are independently listed and rated on Parfumo and reviewed by perfume critics means the person across the table has skin in the game.

The session runs about three and a half hours in Pimlico, central London, for £150 - long enough to get past the novelty and into the actual craft. You work with over thirty-five different ingredients, and crucially you write your formula down. That is the detail that separates a workshop from an activity: you leave with a 15ml bottle, a workbook, and a recipe on file, so a scent you liked can be recreated at 50ml later rather than being a one-off you can never have again.

The register is small-group and technical rather than party-and-prosecco. If you want a laugh with friends and a photo, there are cheaper and breezier options on this list. If you want to understand why a formula works and to be corrected by someone who composes professionally, this is the London session to book.

One practical note: booking runs through phone and email rather than a slick checkout, which is what you would expect from a working perfumer rather than an experience company. Treat the slight friction as a signal about where the money goes.
