Syrah (also known as Shiraz) is a dark-skinned grape variety grown throughout the world and used primarily to produce red wine. DNA profiling in 1999 found Syrah to be the offspring of two obscure grapes from southeastern France, Dureza and Mondeuse blanche. Syrah should not be confused with Petite Sirah, a synonym for Durif, a cross of Syrah with Peloursin dating from 1880.
The style and flavor profile of wines made from Syrah is influenced by the climate where the grapes are grown with moderate climates (such as the northern Rhone Valley and parts of the Walla Walla AVA in Washington State) tending to produce medium to full-bodied wines with medium-plus to high levels of tannins and flavors of blackberry, mint and black pepper notes. In hot climates (such as the Barossa Valley of Australia), Syrah is more consistently full-bodied with softer tannin, jammier fruit and spice notes of liquorice, anise and earthy leather. In many regions the acidity and tannin levels of Syrah allows the wines produced from the grape to have favorable aging potential.
