For many reasons, wine tasting is very difficult
First, on a cultural point of view, olfaction is not a sens we really educate. The very first things we would teach toddlers are colours not the smell of banana or liquorice. This lack of olfactive education makes it very difficult for human beings to put words on olfactive stimuli.
Another reason which makes tasting difficult is the social aspect of it. We are always a bit scared of getting it wrong, being ridulous, saying it smells like ham where in fact it was hibiscus flower. And as a result, the group would expulse us from the cave and we would be eaten by dinosaurs...
Maybe the biggest issue is that we are really bad at smelling. Physiologically we haven't got that much olfactive captors. Dogs for example are much better than us.
We are really good at seeing things, we see colours, and 3D, we see things that are close and things that are far away. But even with this really powerful sense, we stuggle sometimes to put the correct words on what we see ! For example, which colour is this square ?

For some us it 'd be green, for others it would be blue. So even with ths highly developed sense, we can't gove a definite answer ! So imagine the difficulties we face with smell...
Science and technology allow to precisely answer the question of the colour of the square, in any Pantone colour-chart, this is 320C, no matter where we are, the temperature or the time of day, this is 320C, this is an absolute.
But sofar science and technology fail to achieve this unquestionnable absolute for smells.
So our main problem remains, how to express the sensation we feel when tasting wine ?
Maybe a solution would be not to try to put WORDS on what we feel but to express it in another way.
I gave the question some thought 2 weeks ago, as I was in Milan for a tasting event. Chiara Giovoni who wrote the tasting sheets in Italian for the event associated each Champagne of the night with a painting.
I find this idea both brillant and effective. A few days before the tasting when she asked me who my favourite painter was, I imagined that was what she had in mind and started to think about what association I would make for each Champagne. And for the Absolument Brut we both chose :

To be honnest, the choice was limited to Matisse, Van Gogh et Klee. But us choosing the same painting is actulally not the point. the point is there are different ways of describing a wine than words.
We can refer to season or occasions : a Christmas wine, spicy and exuberant, a autumn wine with hints of nuts and fruit compote. We can refer to musical pieces or to landscapes.
"Take Five on a deserted beach" could say much more about what you feel than ready made sentences.
The main thing, the only thing that we really matters is that it should be YOUR description, not your neighbour's, not the latest ultimate wine-book.
