Wines are also classified as Table, Sparkling, or Fortified. Table wines, the natural or still wines, may be Red, Rose, or White, with alcoholic content from about 7 to 15 percent. Sparkling wines, effervescent or bubbling, are most frequently White, and have alcoholic content similar to that of Table wines. Fortified wines contain added brandy and may be Red or White, with alcoholic content from about 16 to 23 percent. Wines may be named for place of origin or grape variety used, or may bear generic names.
Most wines take place-names.
Wine labels may show the vintage, meaning the year in which the grapes used were harvested. The vintage is an important indicator of the wine's value because seasonal variations in weather affect harvest quality from year to year. Wines blended from several vintages bear undated labels. The leading wine-producing countries include France, Italy, and Spain. Greece is also an important exporter of wine, especially the last years.
