Creed call many Millesime strength, which you will see on some of their bottles such as Green Irish Tweed. The bottle of Original Vetiver I can't see the wording Millesime on it and I can't remember seeing it on my bottle of Aventus before I sold it. Millesime is supposed to be EDP strength as far as I'm aware, although many bottles I've tried vary from lasting between a couple of hours to about 6-7, so it depends on your skin. I've got a decant of Aventus and that only lasts a couple of hours on me, so it's more like EDT. I've not tried Vetiver, so I've no idea what strength that one is.
