Citrus

Apple's scent is crisp, slightly tart, and refreshingly green—like biting into a just-picked Granny Smith on a cool autumn morning. It carries a natural sweetness balanced by a subtle astringency that tingles in your nostrils, reminiscent of apple skin rather than the flesh. There's an almost waxy, fruity brightness to it, with a whisper of green leaf underneath. It's clean and invigorating, the olfactory equivalent of fresh air after rain.

Gourmand

Sour milk is precisely what it suggests: the sharp, tangy pungency of yoghurt or slightly curdled cream, with an underlying sweetness that prevents it from becoming truly unpleasant. Imagine the piercing sourness of Greek yoghurt combined with warm, creamy butter—there's a lactonic richness beneath the acidic bite. It's unsettling at first sniff, deliberately challenging, yet oddly compelling. Think of the smell when you open a tub of sour cream on a warm day: that distinctive fermented tang mixed with dairy fat.
