To produce the Bolgheri Superiore DOC “Sondraia” Poggio al Tesoro, after destemming and soft pressing to partially rupture the berries, fermentation took place in temperature-controlled stainless steel tanks at 28-30°C for 12 days. The wine was transferred to French oak barriques (50% new, 50% second-use) for ageing, during which time malolactic fermentation occurred naturally. After 18 months in barrique and a further nine months in bottle, the wine was released.

Most of the Cabernet Sauvignon fruit for this blend was sourced from the three hectare Via Bolgherese vineyard situated at 56 metres above sea level. Composed of coarse red sand, the soils are rich in gravel, well drained and have a clay layer at a depth of 120 centimetres. The planting density is 9,000 vines per hectare. Merlot, Cabernet Franc and the remaining Cabernet Sauvignon was sourced from the 12 hectare Le Sondraie vineyard situated 35 metres above sea level. These soils are free draining, a mixture of clay and sandy silt, with high levels of magnesium and iron. With a density of 7,936 vines per hectare, the vines are cordon trained and spur pruned. The vines have an average age of 19 years.

Poggio al Tesoro is a 70 hectare property in Bolgheri acquired in 2002 by the Allegrini family. It is 50 hectares in size and is planted with Merlot, Cabernet Franc, Cabernet Sauvignon and a small amount of Vermentino. All of the Poggio al Tesoro vineyards are located “soprastrada”, the area to the east of the Bolgherese road that is considered the best spot in Bolgheri. Soils here are complex and varied thanks to minerals brought through centuries by the Seggio stream from the nearby hillsides. A careful mapping of the soil has allowed Allegrini to plant the best variety for each plot. This attention to details continues today with a sustainable and organic approach in the vineyard and mini – vinifications in the winery, where different vessels and techniques are used in order to get the best out of each variety and each plot. This approach is evident when tasting the wines: every year the quality is improving and the wines express the uniqueness of the Bolgheri territory.
