Terre d'Hermès is a very clever, masterfully done citrus & woods combination from perfumer Jean-Claude Ellena, originally envisaged as the male counterpart to Eau des Merveilles, the female-marketed, orange and ambergris fragrance released two years before. With this, Ellena has created something for men which smells different from the usual aquatic citrus combinations out there. Yes this is a citrus and woods combination, but there is something about it so rugged, and yet smooth, earthy yet clean... that it's very hard to put your finger on. What he has done, is introduce a "mineral" note, representing flint, a sharp, cool rock and combined that with vetiver, cedarwood, pelargonium (which is a cold & metallic smelling variety of geranium) and earthy patchouli. It's quite something, and not easy for most people to understand at first.
His trademark signature note is Iso-E-Super, which is a recreation of peppery wood (similar to cedarwood) which combines with the vetiver, the pepper and the cedar to contribute to this "mineral-like" effect. The other thing to mention is the orange and grapefruit. The orange note here evokes not the flesh of the fruit, but the rind, like you have just torn it apart in your fingers and the oily zest has covered them, the strong , pungent smell of fresh orange peel. The grapefruit here is very nice, surrounded by pink pepper and gives the top and mid an almost "sparkling" effect. It's a very cleverly composed fragrance, but one which is not easy to understand at first.
I think if you are a man who is looking for something different to make you stand out, this would be a good choice. I would also say that this strikes me as a "serious" fragrance. It's not one to impress, or to please all the people. It has a "serious" tone to it which is very detached. I wouldn't call it cold, but sort of detached. Confidant and detached. That said, if you want to wear something which you will appreciate (not for others), and you have that type of personality, then go for this. It has a "serious" vibe to it and even I don't think I'm that mature enough to wear it (yet). For some reason I see this fragrance fitting someone like a cowboy, or a man who lives in nature. It definitely gives the impression of being connected with the earth (hence the name "earth of Hermès"). But it's certainly unique, one of a kind for sure. Very unique.
