By the editors · 2 min readThe opening is all citrus brightness—lemon and grapefruit delivered with a crystalline clarity that feels more archival than cheerful. There's an austere quality to the way these notes sit, as if observed through glass rather than inhaled in a sunlit grove.
As it settles, violet leaf introduces a green, slightly metallic edge that tempers any sweetness the rose might bring. The floral heart feels restrained, almost intellectual, more concerned with structure than bloom. This isn't romance; it's contemplation.
The base anchors everything in a haze of labdanum and incense, their resinous weight pulling the composition into something meditative and enveloping. Musk adds a soft persistence without warmth. Opus IV reads like a study in contrasts—luminous beginnings, somber depths—suited to those who prefer their fragrances cerebral rather than sensual, composed rather than expressive.
