This sounds a lot like something I saw on Stuart Wilde's site:

When you say "tastes" do you mean that in a literal sensory sense?

A lady I know in her mid-thirties has recently developed an acute telescopic sense of smell. She was telling me that she discovered to her surprise that she could smell a leather briefcase at a distance of two city blocks. An American friend––a family man in his fifties, told me he could smell people and identify them from across the street. Some, he said, have a very beautiful, very distinct smell, while others are quite vile, even from twenty or thirty yards away.
