ROSE LIQUEUR
Rose liqueur describes a floral idea with a sweet, drink-like accent: think rose petals given the rounded suggestion of a liqueur. The effect can feel more gourmand, or dessert-like, when the composition surrounds it with vanilla or almond-like notes. The term is a scent description, not a standardized ingredient with one fixed recipe.
Amouage lists rose liquor in Blossom Love alongside cherry blossom nectar, with amaretto accord, ylang-ylang and vanilla elsewhere in the composition. Those companions help explain one interpretation; they are not inherent parts of every rose liqueur note. The name does not establish that an actual beverage was added to the perfume. When browsing, consider whether the floral character or the sweeter liqueur impression is emphasized in the full description.
