What distinguishes Old World Syrah from New World Syrah?

But the old world Syrah wine, in particular those from Rhône Valley in France, are known to be earthy in aroma, with notes of pepper, and a lighter style. The wines of this type usually reflect the terroir of the area, showing subtleties of soil, climate, and winemaking customs. On the other hand, the New World Syrah wines, especially from areas like Barossa Valley in Australia and Central Coast in California show up with more fruit flavors of blackberry and plum, meanwhile, the oak-derived notes from barrel aging make them more overtly fruity and structured.
