In Lazio, the whites are the predominant variety — out of 25 DOC wines produced in the region, 20 are white. Mostly Malvasia and Trebbiano grapes and, in lesser quantity, Sauvignon Blanc Chardonnay and Voigner among the white and Cabernet Sauvignon and Franc, Merlot, Cesanese, Syrah, Petit Verdot, Sangiovese and Montepulciano, ripen along the volcanic slopes of the Colli Albani and other areas with soil rich in phosphorous and potassium salts.
