But it's all a matter of taste, you say. It's true that among the perfumes reckoned good or great, there are some that will move you more than others, and some that will leave you entirely cold or even sickened, because either they won't say what you're longing to hear or they say what you never want to hear again. All the same, when considering perfume as an art, it's possible to appreciate when something is done exceptionally well.
If you've tried several perfumes, you know things can go wrong. Many compositions smell great in the first few minutes, then fade rapidly to a murmur or an unpleasant twang you can never quite wash off. Some seem to attack with what feels like an icepick in the eye. Others smell nice for an hour in the middle but boring at start and finish. Some veer uncomfortably sweet, and some fall to pieces, with various parts hanging there in the air but not really cooperating in any useful way. Some never get around to being much of anything at all. The way you can love a person for one quality despite myriad faults, you can sometimes love a perfume for one particular moment or effect, even if the rest is trash. Yet in the thousands of perfumes that exist, some express their ideas seamlessly and eloquently from top to bottom and give a beautiful view from any angle. A rare subset of them always seem to have something new and interesting to say, even if you encounter them daily. Those are the greats. By these criteria, one can certainly admire a perfume without necessarily loving it. Love, of course, is personal (but best when deserved).
