Citrus

Rhubarb smells tart and slightly green, like biting into the stalk of a freshly picked plant. Imagine the sharp, almost sour zing of ripe granny smith apple meets the leafy, vegetal quality of freshly cut grass or rhubarb leaves themselves. There's a candied sweetness underneath—reminiscent of stewed rhubarb with sugar—but the dominant character is brisk, slightly tangy, and surprisingly juicy. It's herbaceous without being medicinal, and carries a whisper of that pleasant astringency you'd feel on your tongue.

Gourmand

Vanilla smells like warmth wrapped in sweetness—imagine the comforting aroma of freshly baked vanilla sponge cake, or a warm bowl of vanilla custard on a winter's evening. It's creamy and soft, almost edible, with subtle woody undertones and a hint of spice that recalls cloves or nutmeg. Pure vanilla is surprisingly complex: it's not aggressively sweet, but rather enveloping, like condensed caramel with a touch of earthy depth. It smells like indulgence and safety simultaneously.
