This land-locked grape grows in a long north-south strip over by the border with Spain. It has various alternative regional names. Síria is the name used in the Beiras, but it is best known by its southern Alentejo name, Roupeiro - this is the most-planted white grape in the Alentejo. Because it has a tendency to oxidise, Síria/Roupeiro is a wine to drink young, In its youth it is exuberantly aromatic, citrus and floral, with hints of peach, melon and bay. It does better in the cool uplands of the Beiras than in the heat of the Ribatejo and Alentejo, and is particularly successful in the Pinhel region in the northern sector of the Beira Interior. The Síria gives high yields, and both bunches and grapes are small.
