It was the house's first fragrance, it remains its most discussed, and it comes in more versions than most shoppers realize.

Aqua Universalis is the fragrance most people mean when they say they want something "clean" from Maison Francis Kurkdjian. It launched in 2009, the year the house was born, and it still defines the Aqua family. But the name now covers more than one product, and the differences matter before you order. If you're trying to work out which version suits you, the complete guide to MFK Aqua Universalis explains the whole picture.

The Idea Behind It

Francis Kurkdjian has said he created the Aqua collection to reinterpret and modernise the eau de Cologne while naturally magnifying its signature. Aqua Universalis was the first of the collection, captured in his words as the sensation of a crystal-clear, luminous freshness. The house is the creation of Kurkdjian and Marc Chaya, and Aqua Universalis is the scent that set its tone.

How It Smells

Retailers consistently describe it as a musky citrus: bergamot and lemon on top, white flowers such as lily of the valley and mock orange, and a soft base of musk. One retailer compares it to a perfectly cut white blouse—clean and timeless. It's marketed as unisex, and the brand's own name for the original is eau de toilette, a lighter concentration than eau de parfum. That shows in the style: it's about transparency rather than weight.

Why It's Called a Signature

• It's the house's origin point. It launched with the house in 2009 and anchors the Aqua family.

• It has an award. It won Cosmétique Magazine's best niche unisex perfume award in 2010.

• It sells as a line. One retail review calls the Aqua range the house's best-selling unisex line.

• It's easy to wear. Its clean, citrus-and-musk character suits a wide range of occasions, which is a common reason people choose it as their first niche purchase.

The Versions, Explained

This is where shoppers get confused.

Aqua Universalis (2009) — The original eau de toilette. Retailers list bergamot, lemon, lily of the valley, mock orange and musk. One comparison site estimates short wear, so it's a light, close-to-skin scent.

Aqua Universalis Forte (2011) — An eau de parfum variation launched in 2011. This is a separate, earlier product from the one below, and it is not currently listed at Esscentum.

Aqua Universalis Cologne Forte (2021) — An eau de parfum from the Cologne Forte collection. Kurkdjian describes the range as modern, long-lasting colognes. Retailers list Italian bergamot, Bulgarian rose, a white floral accord of mock orange and sweet pea, and white musk.

Esscentum lists the original and the Cologne Forte. If you're comparing, check the product pages for the concentration and notes, since sites that list "Forte" and "Cologne Forte" often mix them up.

Which Should You Choose?

• The original: if you want the lightest, brightest version and don't mind reapplying.

• Cologne Forte: if you like the idea of Aqua Universalis but want a longer-lasting eau de parfum with a hint of rose.

• Neither feels right? The same Aqua family includes Aqua Vitae, which Esscentum also lists in both versions—a retailer lists the Cologne Forte version with Italian bergamot and mandarin, a solar floral accord and a musky base.

Try Before You Commit

Because the versions are subtle, a small size is a good way to choose. Esscentum has a Decants collection and Discovery sets, so check whether the one you want is offered that way.

The Takeaway

Aqua Universalis earned its signature status by doing something simple exceptionally well: a clean, luminous citrus-musk that feels effortless. The only real decision is which version—and for most people, starting with the original is the right way to understand what the fuss is about.
