Colloquial term (also discount wine, supermarket wine, industrial wine) for wines produced mostly in very large quantities and often at low prices. They are produced by large producers specifically and exclusively for supermarkets and large retail chains or discounters, often with their own brand names for specific consumer groups, and are marketed under special labels of the houses. The term does not have a wine-law meaning and is also not clear. It does not necessarily mean that the quality of the wine is poor or inferior. In the worse case it is a matter of wines for quick enjoyment, whose causes for the inferior quality lie in unfavourable soil and climatic conditions, qualitatively inferior grape varieties, massive yields from so-called mass carriers, and above all the deliberately simple method of winemaking. Such wines are possibly not bottled at all, but marketed in larger containers as cask wine. Simple bulk wines are often bottled in Tetra Pak (Europe) or Bag-in-Boxes (New World). The term "Schankwein" has a similar meaning in terms of quality.
