If you prefer the great smell of Terre a tad bit milder on your skin, with less projection but huge longevity, this is the one for you.
Take the original EDT, "distill" all its bells and whistles in the opening, tone down the benzoin, promote the grapefruit, introduce flint to the orange, make everything in pure parfum concentration.
The result is a more direct, smoothly rich, linear and more "honest" version of an already avant-garde masterpiece.
I don't give ratings in my reviews but for this... i am obliged:
TdH Pure Perfume is a beauty. I wore it for the first time today and I felt so sophisticated. Even though it is a "pure perfume" it's not strong at all. It is just right and gives off the right projection. I find that TdH EDT is stronger that this one. It lasts a long time on me. I put it on this morning at 7:30am and it is now 8:00pm and I can still smell it. Perfect for any occasion.
Terre d'Hermes Parfum was one of the first fragrances I had at the beginning of this hobby, and has seen me through some not so great times. A restrained orange opening with hints of spices, is followed by a mineral earthy mid and woody base. I can detect some vetiver in the heart and the base, perhaps a hint of cedar as well. It has decent performance on my skin. Really stands out in the crowd of other designer fragrances- a solid release!
As others have noted, this is a smoother, richer, deeper version of TdH.
I really get a pink grapefruit note in the opening. The mineral note is much slower to emerge and is less crisp for a long time. The dry-down is very similar, except that the mineral note is a bit more sea-side (salty breeze) than earthy. A good scent, but I like the original better -- brighter, crisper, more refreshing. When I want TdH those are the things I seek.
