I really admire some of the reviewers on here, the way they can identify the individual notes amongst many in some complex fragrances (2 that spring to mind that I enjoy reading are Off-Scenter and DULLAH). My question is this - Does the ability to do this come naturally or does it require extensive 'training' by smelling samples of individual notes? Or a combination of both? Heck some people can identify differences between very similar synthetics and different e.g sandalwoods. Amazing.

Can these noses also do the same with wines? Does the skill also extend to identifying flavours in wines (or spirits)?
