The soils on which the vineyards stand has varied and complex terrain features with a strong presence of limestone, feature areas rich in marl and pebbles as well as being partly clayey; they sit at an altitude of between 100 and 300 metres above sea level, with a south/south-west exposure.
The harvest, all carried out by hand, began with the Merlot grapes at the end of August and continued in September with the Cabernet Sauvignon, to be completed at the end of September. The harvest was carried out more swiftly in 2020 due to the rapid maturity achieved by the grapes, and the not wanting to exceed the alcohol content, but also due to the lower production. In this Guidalberto vintage, there is a higher percentage of Merlot, compared to the norm, due to the excellent maturity of the grapes, which gave excellent results.
Grapes are sorted in the field during manual harvesting and then selected on arrival in the winery using a sorting table. Gentle pressing and destemming of the bunches to avoid pressure on the grapes and excessive release of tannin. Alcoholic fermentation conducted in stainless steel vats at a controlled temperature maintained at around 27-29°C, without the addition of external yeasts. Maceration in this vintage was reduced a little: about 12-14 days for the Merlot grapes and 13-16 days for the Cabernet Sauvignon grapes, with frequent pumping-over in the air and offloading to obtain more balanced musts, favouring aromatic extraction and softening the tannins. Malolactic fermentation, which began at the end of October and was completed in mid-November, was also conducted in steel without any inoculation. From the beginning of December, the musts were put into barriques for ageing for 15 months.
Once malolactic fermentation was complete, the wine was placed in French oak barriques, and a small part in American oak, where it was aged for a period between the 20 and 25 months. The duration of the ageing is technically decided on the basis of the seasonal trend of the vintage.
