Santal Ember is the reed diffuser we reach for when a room needs to feel warmer than it is. Vanilla, cocoa, and amber open with a soft, creamy sweetness, while cedar and sandalwood settle in underneath, bringing a gentle smokiness that never tips into heavy or overpowering. It's warm without being cloying, and smoky without losing its softness.It's a natural fit for the darker months, though plenty of our customers keep it going year-round in a study, living room, or anywhere they want a scent that feels grounded and a little indulgent without announcing itself.Which size is right for this room? Santal Ember works well in any room in the home, and we'd also recommend it for larger spaces — its woody, smoky base comes into its own in a living room or open-plan space, where the 250ml Large is worth considering, with all 7 reeds in from the start. For a bedroom or smaller room, the 95ml Standard suits just as well — start with 5 of the 7 reeds and add the rest after a week for more throw. Our 120ml refill brings a finished bottle back to full strength.Every Santal Ember reed diffuser is hand-poured in small batches in Kent — the same considered approach we bring to every piece in the Little London collection. Refillable, and designed to be topped up rather than replaced.It sits comfortably alongside our other woody scent, Rose & Oud, if you'd like a pair that share a common thread through the home.
