In Austria, viticulture has been practiced since the time of settlement by the Celts almost 3,000 years ago. The Burgenland municipality of Zagersdorf and the Lower Austrian municipality of Stillfried in the Weinviertel are considered to be the oldest wine-growing communities in Austria. Grape seeds dating back to 700 and 900 BC respectively have been found in both places and can be clearly assigned to the species Vitis vinifera. The lifting of the ban on planting vines outside Italy by Emperor Domitian (51-96) by Emperor Probus (232-282) had a positive effect on viticulture. This was the beginning of an orderly viticulture in the Roman provinces of Noricum (Upper and Lower Austria) and Pannonia (Burgenland). In the almost 200-year-long turmoil of the migration of peoples from the end of the 4th century, viticulture almost came to a standstill due to many devastations.
