Vienna (Wien) the capital city of Austria surprisingly is the world's most developed wine region-capital. It is located in the east northern part of the country on the Danube river banks. The vineyards are found all around the city in the suburban area, which is very hilly in most of its part. Viticulture has been practised since the late Middle Ages, vines have been grown within the city walls in what is now the First District of Vienna. Traditionally the wines of Vienna have been destined to be drunk at a very young stage soon after the harvest in the so-called Heuriger taverns around the city. The most popular planted grape varieties are Grüner Veltliner, Riesling, Pinot Blanc, Chardonnay, Zweigelt and Pinot Noir with a local special wine called Gemischter Satz (field blend), in which different vines are planted together in the vineyard, then also harvested together and fermented together into wine. Vienna wine region has a continental climate with strong influence from the Danube river with rich limestone soils on the northern side of the river which are particularly suitable for growing Gruner Veltliner, Chardonnay and Riesling. Zweigelt and Pinot Noir are mostly grown on the southern side of the river which proves to be more successful. Since 2013 Vienna has received DAC status, and since then has solidified its position as the symbol of Viennese wine and ambassador of Austrian wine around the globe.
