Italy didn't invent wine by the way.  So who did, you might ask.  Well, it has been widely accepted that wine originated in the country of Georgia, some 6,000 - 8,000 years ago.

Until recently, the oldest traces of winemaking in Italy were assumed to date to 3,000 years ago on the island of Sardinia, but new research has discovered a 6,000 year old copper container with traces of tartaric acid and sodium salt which are present in grapes and winemaking.

When we speak about New World wine (ie. Australia, USA, South America), these are countries that are still in their infancy having been making wine for just 50-200 years on average. This means when we speak about Old World wine vs. New World wine, there is a staggering philosophical gap on what "wine" even means. 

Generally speaking, the Old World was making wine for thousands of years, in a way we might call organic and natural by today's standards, without the existence of corporations, technology, chemicals, and marketing and saw no reason to fix what wasn't broken.

Whereas, I'll reiterate, generally speaking, the New World has been making wine in an era where science trumps tradition, where the wildness of wine should be controlled for optimum results with new found chemicals, treatments, machines, and selected yeasts to build up a flavor profile which will appeal to the masses, essentially fitting into the algorithm that will yield high ratings from the often corrupted wine journalists and be sure it can be easily marketed and sold.

The definition of wine states that it is an alcoholic beverage made from fermented grape juice.  That may have been at one time been the beautiful simplicity of the beverage, but sadly it has become one of the most adulterated beverages and that definition has become one of the most misleading statements for the consumer.
