The best wine in the world is the one that you like the most. Meaning that each person perceives the quality of wines in different ways, some people perceive the quality of wines in voluptuous, fleshy, fruity, young characters and on the other hand there are others who perceive the quality in lighter, velvety, delicate, complex, mature characteristics and all of these nuances explain above can also be combined in many ways. Which is better? That depends on the palate of each person, it should not be dogmatic.
I think it’s the same situation as when we eat at a restaurant and we order a tenderloin or filet mignon. The chef will ask if we want the meat undercooked, medium, or well done. He is offering us the best quality and raw material they have but prepared in different ways. For one person one way might be the best but for another may be the worst.
Obviously there are certain minimum parameters to consider a wine of acceptable quality or not. For me a quality wine should be round, meaning it shouldn’t have edges, neither too much wood, acidity, alcohol, bitterness, sweetness, fruitiness, meaning that these sensations need to be blended correctly, harmoniously conjugated and balanced all together. Also it should be original, having a special touch that makes the wine stand out from the rest. I like wines that express the terroir or the place where they come from making it impossible to clone or manufactured it in any other part of the world.
It is also true that young people start drinking young, fruity and easier to recognize wines, as your palate evolves you end looking for things that are not so predictable and when you reach an advanced level of tasting wines like Crianza, Reserves and Grand Reserves are the delight of your senses.
The wines that are truly breaking the ground and drawing the attention of customers, restaurants, critics and sommeliers are completely natural, single state, hand crafted wines, produced by small producers.
