I take the stance that there is no such thing as a wine expert.
A person can gain knowledge about viticulture, winemaking, labels, soils, climate, wine laws and all that stuff but wine is always more than a sum of its parts.
I have spent the last 3 years doing WSET courses, I got a distinction at WSET level 3 in all the papers and have passed with merit the first papers of the Diploma, I make no pretence that I know anything more than anybody else on this forum. I simply followed the ghastly WSET prescriptive formula about tasting and theory and knowing how to answer exam questions.
I simply make two points.
You drink the wine and your palate will not lie to you. It will tell you straightaway if you like the taste or something about it is horrible.
Wine, like music, is always more than a sum of its parts. You can analyse in language aromas and flavours by words that are no more than labels but those labels are no more than expressions of common convenience. We can babble on about red fruit, black fruits, medium tannins and all the rest of it but wine is simply more than that. If we could reduce it to words there would be no point in drinking it.
What is an expert? Someone who has a lot of knowledge about component parts. That knowledge means nothing if you do not like what you taste.
Knowledge should be used to help us explore further and find our own way. Never be impressed or overawed by what somebody may know. Just keep exploring and trying different wines.
Wine is a shared pleasure.
People may say “I know what I like” when in fact they are saying “I like what I know”.
Thousands of books have been written about wine, and I have no doubt many more will continue to be spewed out but your own adventure is the only thing that will help you. Just try something different and then read about it afterwards. The stories about growers and vineyards are fascinating in themselves but they are secondary.
Forget scores, forget critics. just pick out bottles and try them. Wine, like great music is a never ending journey of joy, disappointment, but above all a sensuous pleasure.
