Notable FactsUnlike its Chilean neighbor, Argentina's vineyards are spread out around the country. The best known region is Mendoza, almost parallel to Santiago to the west. Mendoza contains the sub-regions of Maipu (pronounced MY-pu) and San Rafael. Grape-wise, the most important white is Chardonnay, making wine similar to California's style on the variety. Another fun white grape to try is Torrontes. Almost only grown in Argentina, Torrontes makes wines that are crisp, aromatic and easy-drinking. Some of the best versions of this wine come from the northern region of Salta, with very high altitude vineyards. As for the reds, Cabernet Sauvignon is the main grape for many wines leaving the country, but Malbec, the grape Argentinians like to call their own, makes very distinctive wines that are structured, dense and velvety. Many more varieties happily grow in the country, but for export, and consistent quality, these are the primary grapes.
The most famous of the California wine regions is Napa Valley, and these wines are certainly outstanding – but it's not as broad and diverse as its larger neighbor, Sonoma County. Down south, Santa Barbara's Santa Maria Valley is well-known for its Rhône blends, as well as cool-climate varieties like Pinot and Chardonnay. The Central Coast, the largest California AVA, has many different microclimates that lead to a wide range of wines with many sub-AVAs.
