In Germany, a common name for winegrowers derived from Weinhacke (wine hoe), see there.
The German term vintner is derived from the Latin "Vinitor" (from Vinum = wine) and means "grape picker" (Weintraubenleser). This suggests that in earlier times it meant only the activity of growing grapes, i.e. without the process of wine production. Today, in German-speaking countries, this is not an unambiguous occupational designation, but rather a general, colloquial collective term for the group of winegrowers, regardless of the scope of the activity, from the pure grape supplier to the wine producer (cellar master). As a rule, however, today only a wine production enterprise is referred to or understood as a vineyard.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.Sigi Hiss
