The origin of a wine is probably the most fundamental quality factor. The term 'terroir' has become a much discussed slogan in recent years, and opinions differ on the question of “what is terroir?”.
Does it mean the soil on which the vines grow? Or is the climate also a key factor? What about the type of viticulture or vinification of the wine? There doesn't seem to be a right answer.
Austria is a cool climate country. The role of the climate is therefore quite significant, which when coupled with the soil structure in the vineyards, and a multitude of other factors, contribute to the regional terroir.
