No. 41 centres on a single listed note: Iso E Super. The Scent Reserve describes its aroma as subtle, woody and velvety, with a minimalist, contemporary character that can mingle with your natural scent. No middle or base notes are listed, so there is no larger note pyramid to work through; the fragrance stays deliberately pared back. It may appeal if you enjoy clean woods and prefer a simpler scent profile over a layered mix of florals, fruit or spice. Wear it on its own for an understated impression, or try it beneath a favourite fragrance if you enjoy experimenting with layering.

This is a 100 ml unisex Parfum, made and bottled in the UK by The Scent Reserve. The brand describes it as vegan-friendly and cruelty-free. No. 41 is The Scent Reserve's own fragrance, inspired by Iso E Super; it is not the original Molecule 01 fragrance, and the brands are not affiliated. Wye Knot is an official stockist of The Scent Reserve. If you are choosing a gift or comparing woody scents, our independent shop in Builth Wells is happy to help you consider whether this single-note style feels right.
