Montero's portfolio demonstrates his ability to create cultural dialogue through fragrance, crafting compositions that pay homage rather than imitate different traditions. His work for Memo Paris includes Madurai , which captures the essence of Indian culture and architecture through jasmine sambac and sandalwood, as well as Cappadocia, where saffron acts as a central element within a resinous, amber composition.
For 27 87, Montero created Mosaïque , a complex blend that contrasts cool smokiness with a mystical sweetness, featuring notes of tobacco, honey, and roasted cocoa. Rule of 72 highlights his mastery of darker compositions, combining Thai oud with leather and vetiver in a refined, confident blend that expresses itself with subtlety rather than intensity.
His collaborations with Fragrance Du Bois include Cavort , an intimate composition built around saffron and davana, and Tropiques , which evokes a tropical atmosphere through bergamot and exotic fruits. For Attar Collection, he created Fleur de Santal , a delicate sandalwood-based fragrance, as well as Sierra, a modern spicy-woody composition featuring pink pepper and incense.
Montero's philosophy is rooted in the idea of perfumery as both art and science. He believes that fragrance expresses a deeply personal identity meant to be shared. His long-term vision is to recreate the "magical scent" of the sun-warmed flora of his Spanish childhood, bringing his multicultural journey in perfumery full circle.
