Vermentino is a Mediterranean white grape variety grown mostly in France Italy, Corsica and Sardinia, though the variety is gaining momentum here in Australia too.
Vermentino grapes are typically used to produce light, attractively aromatic wines with refreshing acidity and leafy, lemon-tinged flavors. Any Sauvignon Blanc enthusiasts out there would be well advised to try a vermentino next time for something new!
The exception to the rule would be the Vermentino wines of Bolgheri in northern Tuscany. They are more highly regarded for their depth and complexity, and can be likened to Viognier for their floral, slightly soapy characteristics.
