Maison 21G

Maison 21G was founded by French perfumer Johanna Monange, who spent twenty years composing for houses such as Firmenich and IFF. The name comes from 21 grams, said to be the weight of a soul, and the idea that each person deserves a perfume of their own. The brand presents itself as a Paris house, but in November 2021 Premium Beauty News described it as a Singapore brand founded two years earlier, with three shops in the city.

It sells made-to-measure perfume. You pick from 52 essences, made to pair with each other, and the eau de parfum is 21% perfume concentrate. Your formula is kept on file, so you can reorder it at any time. The house says its perfumes are vegan and refillable. There is a ready-made range too, such as Sage & Ocean or Rose & Honey, at S$150 for a 30 ml set.

The house set the opening of its new Maison de Création at 3 Duxton Hill for 10 September 2026, and lists it as open daily from 12 pm to 8 pm. A one-hour private workshop costs S$200, and you leave with a 30 ml eau de parfum you composed, in a bottle you name and have engraved. It also lists counters at The Shilla Duty Free in Changi Airport Terminals 1, 2 and 3. For a souvenir, try the Scents of Singapore set: four 5 ml sprays inspired by places in the city, for S$100.
