History
Aqaysos appeared in 2017 in Pierre Guillaume’s Black Collection, the house’s line of deep, statement woodies. Its inspiration is twofold: crystal on the one hand, for its incisive, shiny and brilliant character; modernist architecture on the other, that of a smoking room designed by Robert Mallet-Stevens, between the 1930s and the cold elegance of cut glass.
The perfumer’s choice is to imagine a wood of crystal: a smooth wood that would capture and reflect light while keeping the grain of the material. To obtain that chatoyant effect, Pierre Guillaume plays resonances between ingredients, cold spices and light cashmere woods, so as to distort our perception the way a prism diffracts light.
The opening rises in fruity, incisive notes, carried by sansho berries, that bright, lemony Japanese pepper. The heart lets cocoa beans and crystalline woods rise, giving the fragrance its smooth texture and its shine. The base of musk and amber lays down a discreet warmth, a velvety depth beneath the transparency of the crystal.
Aqaysos is thus an elusive woody, a versatile proposal that plays on fluidity and transparency as much as on impact. Within the house it sits alongside Le Musc & La Peau, Liqueur Charnelle and Komorebi, all compositions where Pierre Guillaume cultivates a mineral, aqueous-floral and spicy signature.

Pierre Guillaume does not publish a formal pyramid: the layout below follows the progression described in the catalogue, from rising notes to crystalline wood.
The thread is the crystal effect: the resonances between cold spices and light woods distort perception like a prism.
Olfactory profile
Aqaysos is a crystalline woody rather than a warm one. The perfumer seeks the effect of cut glass, a smooth, shiny wood that reflects light, obtained through the contrast of rising sansho berries and light cashmere woods. It is a transparent, incisive woody, far from the opaque ambers of the Black Collection.
Its signature lies in this tension between transparency and impact: the fruity freshness of sansho, the dryness of cocoa, the shine of crystalline woods, held by a base of musk and amber. The result is a versatile, elusive woody, unisex and statement-making, whose bright, mineral trail wears by day and at the office.
Aqaysos is inspired by the incisive, shiny and brilliant character of crystal.Pierre Guillaume Paris, catalogue 2025–26
