Smelling and tasting wine

Most of what you taste is smell — and describing it is a skill, not a gift.

The short answer

Most of what you call taste is smell. The tongue reports five things — sweet, sour, salt, bitter, savoury — and everything else reaches you through the back of the nose while you swallow.

Overview

Your tongue detects five tastes. Everything else you think you are tasting, you are actually smelling, through the back of your nose. Blocking your nose and drinking wine makes this obvious immediately.

That is why swirling helps: it releases volatile aromatic compounds. It is not a performance.

Describing wine is a matter of practice and vocabulary, not a natural gift. People who are good at it have mostly learned a list of reference smells and attached names to them.

A useful starting framework: is it fruity, and which kind of fruit — citrus, orchard, stone, tropical, red berry, black berry? Then is there anything that is not fruit — herbs, spice, flowers, earth, vanilla, toast?

There is no correct answer. If you smell blackcurrant and someone else smells plum, you are both reporting your own perception honestly, and individual sensitivity to specific compounds genuinely varies.

Where you can see it

Testing it
Hold your nose, take a sip, then let go. The rush of flavour when you release is the part your nose was doing all along.
Descriptors are analogies
A wine described as smelling of blackcurrant contains no blackcurrant. The compounds simply overlap with ones your memory has filed under that name.

Go shallower or deeper

The beginner page and the chemistry page are both correct, and neither substitutes for the other.
