Until recently, sherry was the major Spanish wine sold. Today, Rioja, a leading table wine, is Spain's most widely exported wine, and Ribera del Duero, Priorato, Navarre, and other regions also produce fine wines. Portugal, best known for port and Madeira, also produces some excellent table wines. Greek wines, mainly whites and rosés, are sometimes treated with pine resin (retsina). Australian wines have sold well since the mid-1980s, when first-class examples of chardonnay and cabernet sauvignon became available abroad; New Zealand is especially noted for its sauvignon blanc. The best wines from South America come from Chile, which produces both fortified and table wines; Argentina is another significant producer. French planting has made Algeria one of the largest wine-producing countries, but the wines are not notable. Other wine-producing countries include Austria, Hungary, Romania, Bulgaria, and South Africa.
