Do you know the difference and should you care?
The differences in Old World and New World wines come from winemaking practices (tradition) and from the affect of the land and climate on the grapes (the “terroir”). Despite these common descriptors between New and Old World wines, there are plenty of exceptions to the rule.
Old World wines are from Europe, and New World wines are from everywhere else—the Americas, Australia, New Zealand and South Africa. That should be pretty obvious on the label.
