Syrah In the early 2000s, it broke into the top 10 of varieties planted worldwide for the first time. The name "Shiraz", from Shiraz in Iran, was historically applied to a wine unrelated to contemporary Shiraz wines and was made from a grape or grapes entirely different from the Syrah that has been proven to originate in southeastern France. Smaller amounts of Syrah are also used in the production of other wine styles, such as rosé wine, fortified wine in Port wine style, and sparkling red wine. While Australian sparkling Shiraz traditionally have had some sweetness, a number of Australian winemakers
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
