Choose Molecule 01 + Black Tea if you prefer a lighter, more minimal composition that stays close to the skin. Both share Iso E Super, but Guaiac Wood adds depth and darkness while Black Tea keeps things subtle and portable.

The core difference: smoky depth vs. minimal lightness

Molecule 01 + Guaiac Wood combines Iso E Super with guaiac wood essential oil, which brings a warm, smoky, woody aroma profile. Guaiac wood has one of the best dry-downs in olfactory alchemy and contains depth within itself, darkness. That means the fragrance evolves noticeably over hours, settling into a rich, resinous base. Molecule 01 + Black Tea, by contrast, is part of the Molecule + line that celebrates pure aroma-chemicals on a microscopic scale. It stays closer to the minimal, abstract character of Molecule 01, adding a black tea facet without the smoky weight. If you want a scent that announces itself with warmth and evolves, Guaiac Wood is the pick. If you want something quiet, clean, and nearly transparent, Black Tea is the better fit.

Wear time and sillage: what to expect

Guaiac wood's natural tenacity means Molecule 01 + Guaiac Wood typically lasts longer on skin and projects more than Black Tea. The smoky, woody dry-down clings to fabric and hair, so a little goes a long way. Black Tea, being more minimal, sits closer to the skin and may need a refresh after several hours. Neither is overpowering, but Guaiac Wood has more presence. If you work in a shared office or prefer a scent that stays personal, Black Tea's lower sillage is an advantage. If you want a fragrance that carries through an evening, Guaiac Wood delivers more staying power.

Portability and travel: the ATOM.iser. option

For those who want to carry either scent on the go, the M+ Iris ATOM.iser. Set and Molecule 05 ATOM.iser. Set offer a twist-and-spray, travel-sized fragrance case. The ATOM.iser. is crafted from metal blasted with stainless steel 'sand' for a soft lustre and anodised for durability. It is designed to elevate your on-the-go lifestyle and keep your favourite EM scent at hand. Note that these sets are specific to M+ Iris and Molecule 05, not Guaiac Wood or Black Tea, so if you want a portable format for those two scents, you would need to decant them into a separate travel atomiser. The ATOM.iser. sets are a good choice if you already own or plan to own M+ Iris or Molecule 05.

Product facts

  • Molecule 01 + Guaiac Wood: Molecule 01 + Guaiac Wood consists of Iso E Super + Guaiac Wood. Guaiac wood is an essential oil found in the heartwood of the Bulnesia sarmientoi tree with a warm, smoky and woody aroma profile. Guaiac Wood has one of the best dry-downs in olfactory alchemy. It contains depth within itself, darkness. This explains why Guaiac Wood feels richer and more evolving than a minimal molecule scent, making it suited to evening wear or cool weather.
  • Molecule 01 + Black Tea: The most minimal fragrance is a single aroma-molecule: Molecule 01. The next most minimal adds 1 to 01: 01 + 1. This is Molecule +. Similar to their Molecule counterparts, fragrances from our Molecule + line delve into the intricate world of aroma-chemicals, celebrating their pure and distinct qualities on a microscopic scale. This positions Molecule 01 + Black Tea as a subtle, close-to-skin option for those who want a barely-there scent that still has character.
