Hunter Valley wine rot), "Greeneria uvicola" (bitter rot) and other fungi from the genera of "Aspergillus, Penicillium" and "Alternaria". Susceptibility of certain wine grape varieties were found to increase as the grapes reached higher Brix sugar levels. Further research in the 2000s, showed that some of the open canopy techniques used to prevent "Botrytis" grey rot may actually promote the development of some of these other types of rot. Ripe rot, in particular, seemed to thrive at the higher ultraviolet B (280–320 nm) light exposure that open canopies allow. To compound the potential problem for Hunter Valley wine growers is that, as of
Straw wine Czech wine law, is classified as a Predicate wine (Czech: "Jakostní víno s přívlastkem"). Czech regulations require the harvested grapes to come from a single wine sub-region, the grapes must be dried for at least three months either on straw or reed mats or hung in a well-ventilated space, and the must weight is required to reach at least 27° NM on the Normalizovaný moštomer scale. Straw wine in the Czech Republic is typically made from white grapes that are well-ripened and undamaged. Vin de Paille is the French for 'straw wine', made only in the ripest vintages. Perhaps the
