What's wrong with Californian, South African, Australian or Chilean wines?
There's a lot of subpar SA wines. But there are great wines from all over the world... Chile has some fantastic stuff, California, New Zealand, etc.
People get hung up on expectations and let it cloud their experiences a bit too much I think. Because it doesn't take 20 generations to make good wine, and just read
The Judgement of Paris about this phenomenon. There's nothing so special about Bourgogne vines, grapes, skill and terroir that isn't impossible to reasonably compete with by making other wines in their own terroir in skilled hands. Maybe you cannot recreate a top-notch Grand Cru pinot in the Casablanca Valley of Chile, but dammit if you can't make something that reflects its own terroir and merits of its climate, soil, and grapes that nothing in the world couldn't touch. Nobody has a monopoly on good wine -- just look at Shiraz, Iraq.
Screw tops are another perfect example of the myths behind the aesthetic masking actual taste judgment.
If you're the curious type, bianconero, I strongly suggest you do some blind tastings in capable hands to prove it to yourself to get over your preconceived biases.
