If you were to taste it right before bottling, you would think it less drinkable than pine-sol. After the appropriate amount of time, however, it becomes a delicious, amaretto-like dessert drink. It really is fascinating how much it changes over time.
Yeah but we expect some trends among professionals, don't we? Just like we'd expect all food critics to rate McDonalds below French Laundry. Wine ratings are all over the map for professionals, amateurs and everyone in between.
Taking this further, wine experts usually specialise in a particular region. Learning the wines of a region like Burgundy is a lifetimes study. If you ask a Burgundy expert for a wine around £50 to go with shellfish, don't be surprised when they recommend a Meursault. As an expert in New world wines you might get very different answers.
A relative of mine did some work for a winery. As part of the payment or as a gift for a job well done they got a bottle of wine from 1965. The bottle was covered and dust and grime, looked pretty gross. By that time we drank it it had aged for about 25-30 years. The taste though was amazing. Didn't even taste like wine, had a very smooth velvet-y taste. Almost no acidity, not tannic at all.
My wife likes strawberries. I don't care for them. Professional wine tasters are just people with their own preferences.
> aging a particular bottle actually makes it taste better in a measurable way.
So Bordeaux 2017 is on sale now En Primuer, which means it is still in big casks in the vineyard. Buy it now and your wine merchant will ship it to you in 18 months when it is bottled. The wine experts have all been to Bordeaux and tasted those wines, and I can tell you you need to be an expert....because this young they are very tannic (like sucking a tea bag!). The skill they display in knowing how good a wine will be in a few years when it is ready is pretty impressive. These wines will all taste very tannic in 5 years time, but in 10 years may soften. So no they don't get better with age, it just takes years for them to be ready to drink. I guarantee you could tell the difference between a 2017 claret and a 2009 claret.... because one is ready, one is disgusting. So sorry I think you have missed the point of ageing.
