VOC Znojmo

Wine marking methods

Predicate wines – cabinet min. 19° NM
Predicate wines – late gathered min. 21° NM
Predicate wines – selection from grapes min. 24° NM
Predicate wines – selection from berries min. 27° NM
Predicate wines – ice wine min. 27° NM
Predicate wines – straw wine min. 27° NM
Predicate wines – selection from botrytic berries min. 32° NM

B. Roman wine-marking – Appellation System
