Cultivated since the 1970s, Patata dell’Alto Viterbese refers to potatoes of the Amber, Monalisa, Agria and Agata varieties, grown within the province of Viterbo in the fertile, mineral rich volcanic soils north of Lake Bolsena. Having a particularly high content of calcium, potassium and vitamin C, potatoes from northern Viterbo are prized both locally and across the country. Amber and Monalisa varieties are known to be suitable for all uses, although they are most often used for oven-baking and making gnocchi. Thanks to the elevated presence of dry matter, the Agria variety is most suitable for deep-frying and Agata is ideal for steaming and making croquettes or mashed potatoes.
