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
Mexican wine by clergy. The Santo Tomás Mission, founded in Baja California by Jesuit priests in 1791, reactivated larger scale production of wine in Mexico. In 1843, Dominican priests began growing grapes at the nearby Nuestra Señora de Guadalupe del Norte mission, located in what is now called Valle de Guadalupe. This valley is one of the few in the world, along with others such as the Napa Valley and the Rhone Valley, in which premium wine grapes can be grown. In the 1850s, as part of Mexico’s Reform War, many of the Church’s land holdings were taken by the state. Most
