There are thousands of perfumes on the market. They're as manifold and distinct as wines but far more important to get right. Which, after all, is more likely to spoil your meal: a bad cabernet in your own glass, or a bad perfume or cologne on anyone in the room? Besides, the mystery of wine is mitigated by an enormous wing of writing: histories, guidebooks, magazines, Web sites. Not so with scent; there's almost nothing to steer the novice. At least, there hasn't been until now.
