Young Curly Red Haired Girl In The Vineyard

There are also changes in the kinds of grapes grown. For example, in Chile, large areas of low-quality grapes have been replaced with such grapes as Chardonnay and Cabernet Sauvignon. Grape changes are often in response to changing consumer demand but sometimes result from vine pull schemes designed to promote vineyard change. Alternatively, the development of "T" budding now permits the grafting of a different grape variety onto existing rootstock in the vineyard, making it possible to switch varieties within a two year period.
Local legislation often dictates which varieties are selected, how they are grown, whether vineyards can be irrigated and exactly when grapes can be harvested, all of which in serves to reinforce tradition. Of course, changes in the law can change which grapes are planted. For example, during Prohibition in the U.S. (1920–1933), vineyards in California expanded sevenfold to meet the increasing demand for home-brewing. However, they were largely planted in varieties with tough skins that could be transported across the country to home wine-makers and the resulting wine was of low quality.
