Do California wine makers make their wines differently than say,France,Italy and other foreign countries?

Wine making for the most part is a standard practice world wide. Still wine makers generally all follow the same procedures, with minor (although to them and the taste of the wine the differences are huge) difference such as the storing of the wine in new or old French oak. Some wine makers do place additives or enhancers in the wine to add flavor (think oak). This is more prevalent in bulk wine (think gallon or box containers) or inexpensive wines (say less than $10.00). Your leg cramps maybe tied to an additive or prese4rvative the wine maker has added.
