The largest wine region in the country is located in the province of Mendoza and it is this region that I have focused on for this website. The other provinces of and San Juan (Cuyo region), and La Rioja. Salta, Catamarca and Río Negro are also fine wine producing regions, but at this time they will have to wait while I complete the website. The Mendoza Province produces more than 70% of Argentine wine and is the source of an even higher percentage of the total exports .
Mendoza, with several hundred wineries in operation, and more opening every week, the region has become by far the most popular region in Argentina for wine tourism. The Mendoza region starts at the base of the Andes Mountains in the northwest and is the gateway to the Chilean border.
There are 1,221 wineries producing Cabernet Sauvignon, Malbec, Merlot, Syrah, Barbera, Riesling, Chardonnay, Sauvignon Blanc, Chenin, Ugni Blanc, Semillón. On the northern region, the most typical wines produced are white and young red wines, while the eastern region is the area of most vitiviniculture production.
The wine harvest festival, Vendimia, which falls on the first Saturday of March, actually begins in January in various locations around the province and then zeroes in on the city of Mendoza. The celebrations include folkloric festivals, religious ceremonies to bless the grapes, crowning of the Reina Nacional de la Vendimia, sports events and a lot of wine and merriment on into April.
