Royal Water is another on of the Creeds that is very "batch" specific for me. I have owned a 1oz. bottle and had three other official Creed, carded samples and all have differed greatly.
Two of the samples were heavy on the cumin, one more so than the other, one of the samples was almost completely citrus that faded very quickly and the bottle,(thankfully) was a nice, integrated mix of supposedly all that Royal Water is but it seemed to really lean toward the feminine side of unisex where all three of my samples seemed more masculine to me.
I appreciate the natural ingredient factor, the "millesime" idea but I find it too frustrating to deal with these inconsistencies on a regular basis.
I hope your wife enjoys the Royal Water!
