Syrah through their partnership with Woodinville, Washington-based Columbia Winery and Master of Wine David Lake. Expanding at a significant rate, it is used to produce single-varietial wines as well as being blended with grapes such as Grenache, Cinsault, and Viognier. Syrah plantations in Argentina increased from less than in 1990 to in 2002. Syrah has occasionally been used as a blending component with Argentina's signature dark-skinned grape Malbec to provide an "Argentinian take" on the Australian Cabernet-Shiraz blend. Around 2005, there were of Syrah in Chile. Durif, or Petite Sirah, is a descendant of Syrah and Peloursin. It was propagated by
Phenolic content in wine concentration in the skins of wine grapes. The accumulation in ripe berries of different concentrations of both bound and free resveratrols depends on the maturity level and is highly variable according to the genotype. Both red and white wine grape varieties contain resveratrol, but more frequent skin contact and maceration leads to red wines normally having ten times more resveratrol than white wines. Resveratrol produced by grape vines provides defense against microbes, and production can be further artificially stimulated by ultraviolet radiation. Grapevines in cool, damp regions with higher risk of grape diseases, such as Bordeaux and Burgundy, tend to
