Is there a job identifying scents, called "The Nose"?

Question

I heard/read that there are few people with very keen sense of smell who are called a Nose who identify scents. Is this true? If so, what type of jobs are for these people? And what it the job title actually called?

Answer 1

I have seen articles saying that coffee roasters and perfume blenders employ them. I don't think it is a large career field though.

Answer 2

There are individuals in the wine industry who can sniff wine blindfolded and identify the variety of wine, what winery bottled it, what year it was produced, etc.
