The majority of Austrian grapes are grown on small estates with the average winery covering less than 7 acres. This results in high quality wines, many with single vineyard status. The production on these family run estates constitutes for less than 1% of the worlds wine, with the majority (75%) consumed locally. The majority of the wine grapes regulated for growing are white, due to the climate. The most famous of the indigenous grapes is the hardy Gruner Veltlinger which is known for its citrus fruit, herbaceous character and explosive acidity. Gruner is very important to the Austrian wine market as it makes up approximately 1/3 of all plantings.
