Sterparo vineyard takes its name from a plot of land about 4 kilometres from Prossedi, under Roccasecca dei Volsci, at 80 metres of altitude. It was planted to Sangiovese, Barbera and Merlot in 1950. It faces south-east and is situated beside the Amaseno river. All recent plantings have been made from massal selections from within the original vineyard. The first vintage was 1998.
Type of wine: Red wine produced from vineyards cultivated using sustainable farming methods and now being converted to organic.
Denomination: Lazio Indicazione Geografica Tipica
Grape Varieties: 40% Sangiovese, 40% Barbera, 20% Merlot
Production area: 4 kilometres from Prossedi, beside the river Amaseno, in the Sterparo vineyard
Soil: From an original flood plain, the soils are clay with lime, rich in organic material, with some iron, alluvial graves and with a large percentage of sandy scheletro. The river Amaseno’s passage here through the centuries has contributed to the soil’s fertility.
Plants per hectare: 4,000
Training system: Guyot
Vineyard age: Planted in 1950 with some additions in the early 2000s
Harvest: Manual, by the end of September
Vinification: After the selected grapes have been crushed and de-stemmed, fermentation begins between 28-30°C. The maceration takes place in small oak barrels (of 33 quintals) for 16-20 days with daily punching down and over. In March-April the new wine is transferred to French barriques (new and second-passage); after 18 to 20 months of aging the wine is assembled and bottled. It is then bottle-fined for at least 6 to 8 months before being sold.
