Principal grape varieties

Terroir

• The production zone lies in the mid-hillside belt, with gently sloping surfaces formed on alluvial deposits of varying age or on lacustrine Villafranchian sands.
• In some steeper stretches, Miocene marls and sandstones outcrop, where gradients readily reach 30% and sometimes exceed that figure.
• Soils destined for viticulture have a predominantly loam, silt loam, or clay loam texture, with a good calcareous content and a sub-alkaline reaction.
• From a taxonomic standpoint, the soils are classified as Entisols and Inceptisols according to the Soil Survey Staff classification of 2010.
• The vineyards are situated at elevations ranging from the valley floors, which are excluded from the appellation, up to 550 metres above sea level, with varying gradients and aspects.
• Mean annual rainfall ranges between 800 and 950 mm, although in years such as 2010 precipitation in excess of 1,100 mm was recorded.
• In 2011, a particularly rainy year, mean precipitation values of 1,184 mm were recorded across the zone.

• The local Vinsanto, linked above all to the area of Città di Castello, gained renown through Girolamo Serafini, who received awards at exhibitions in Brussels, London, Rome, Florence, and Gubbio between 1908 and 1909.
• The designation of origin was recognised by Decree of the Ministry of Agricultural Resources of 22 January 1980.
• The principal grape varieties suited to production, traditionally cultivated in the area, are Grechetto, Trebbiano Toscano, Sangiovese, Merlot, and Cabernet Sauvignon.

• The red wines display a vivid ruby colour with a purple rim, shading toward garnet red in more aged examples.
• Across all red wine types, floral aromas are found alongside fruity notes of cherry and raspberry, sweet spice, and chocolate, which in more aged wines shade toward spiced or phenolic notes associated with wood.
