Subzone (also Valle Isarco) for white wines and red wines in the Alto Adige DOC area in the Italian wine-growing region of South Tyrol (in the dual region of Trentino-South Ty rol). The zone includes vineyards at up to 800 metres above sea level on both sides of the Eisack (Isarco) river northeast of Bolzano (Bozen) in Barbian (Barbiano), Bressanone (Brixen), Feldthurns (Velturno), Kastelruth (Castelrotto), Klausen (Chiusa), Lajen (Laion), Natz-Schabs (Naz-Sciaves), Ritten (Renon), Vahrn (Varna), Vilander (Villandro), Villnöss (Funes) and Völs am Schlern (Fiè allo Sciliar). If the grapes come from classified vineyards, Vigna plus the name of the vineyard may be indicated.
The wines are produced from up to 85% of the respective variety and max. 15% of other permitted varieties. These are the white wines Kerner, Müller-Thurgau, Pinot Grigio (Pinot Gris), Riesling,Sylvaner (Silvaner), Traminer Aromatico (Gewürztraminer) and Veltliner (Grüner Veltliner). There is also a Passito, a Vendemmia tardiva (late harvest) and a Riserva (except Müller-Thurgau) of all of them. The red wine Klausner Laitacher is blended from Vernatsch varieties (Schiava) and/or Porthoghese (Blauer Portugieser) and/or Pinot Nero (Pinot Noir).
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
