The absolute benchmark for premium wine is the ability to show the vineyard and the grape variety. That's what you've got that no one else can replicate. A place in the world, and a grape variety to act as the medium to portray that, and give an understanding of place that nothing else can. That's it. That's most of wine.
But... look I've gone down a bit of a rabbit hole over the past five years or so. Exploration of different winemaking styles, and regions and cultures. Basically a lot of drinking.
