At the time of building their monastery in 996, the Benedictine monks also revived the viticulture developed by the Romans. Pannonhalma had its own winery until confiscated by the Communist government after 1945. The monks continued this tradition when on a 2000 square metre plot they built a new cellar and wine-house in which they have been processing wines since the autumn of 2003. Due to the planting work started in 2001, about 50 hectare newly-planted fields are at the winery's disposal. In two-thirds of the vineyards white grapes can be found such as Rheinriesling, Sauvignon Blanc and Gewürztraminer, but the traditional breeds of the region as Welshriesling and promising international grapes as Chardonnay or Pinot Blanc are also part of the selection. Pinot Noir is the most significant of the red grapes, but the winery also has Merlot and Cabernet Franc. The variety-specific wine-making technology enables the winery to produce more than 300.000 bottles of quality wine annually.
