French word for the process by which passerillé grapes are dried, shrivelled, or raisined on the vine, concentrating the sugar in grapes-an alternative to wines whose sugars have been concentrated by botrytis.
According to the 2005 wine legislation, the following types of wine are produced in Tokaj: Dry and semi-dry; These are wines vinified from overripe grapes and matured only briefly. Matured dry wines; botrytis is undesirable. Szamorodni; Comparable to that of Beerenauslese. They are fermented dry or sweet and subjected to subtle maturation under a film-forming yeast. Very like the Jura's Vin Jaune. Sweet Aszù wines; Traditionally, the concentration of wines is measured by the number of puttonyos of Aszù grapes. Essencia; The free-run juice of hand-picked botrytized berries with a sugar content of over 450g / l also 800g and more. Essencia takes years to achieve a modest alcohol level of 4-5%.
Chemicals applied to vineyards to control the growth of weeds. They may be either pre-emergent (or residual) or post-emergent (knockdowm). The latter group comprises two types, contact and syntemic herbicides. Residual herbicides act against germinating seedlings of the weeds, while post-emergent herbicides are applied only to the strip of ground directly under the vine, and weeds growing between the rows are controlled by cultivation or mowing.
Downy mildew attacks all green parts of the vine and young leaves are particularly susceptible. When severly affected, leaves will drop off. The loss of leaves reduces photosynthesis and thus causes delays in fruit ripening and, typically, levels of fruit sugars, vine reserves of carbohydrates, and anthocyanins are depressed.
The result of breeding a new variety by crossing two vine varieties. If the varieties are of the same species, usually the European vinifera species, then the result may also be knowm a an intraspecific cross - Müller-Thurgau would be one example.
