The AOC Alsace, established in 1962, concerns wines from parcels that have been rigorously and precisely delimited on the basis of historical production areas. It includes either one of the Alsatian grape varieties, which will usually be mentioned on the label, or a white wine blend, generally with the mention of Edelzwicker or Gentil.
The appellation has been completed by geographical denominations, the "Communales" and the "Lieux-dits", which you can find on the label of the famous long-necked bottle, called "flûte d'Alsace", protected and mandatory for still wines.
The "communal" or "sub-regional" areas have more restrictive regulations than the AOC Alsace: grape varieties, planting density, pruning rules, vine pruning, grape maturity and yields. 13 communes or inter-communal entities have been strictly delimited and can be indicated in addition to the AOC Alsace: Bergheim, Blienschwiller, Côtes de Barr, Côte de Rouffach, Coteaux du Haut-Koenigsbourg, Klevener de Heiligenstein, Ottrott, Rodern, Saint-Hippolyte, Scherwiller, Vallée Noble, Val Saint-Grégoire, Wolxheim.
The "lieux-dits", with even stricter regulations, are delimited according to a particular terroir which offers, in addition to the fruity character of the grape variety, a minerality specific to its soil and terroir.
