The vines are planted in the Valpolicella Classica zone which is a hilly band north of Verona. The soil is composed of clay and silt which tend to be rich in nitrogen, the vines use this to build essential compounds, including proteins, enzymes, amino acids, nucleoid acids and pigments. Clay soils also provide the potassium that vines need to form sugars and starches to encourage bud initiation. The best bunches are hand selected and put in small crates and left to raisin to achieve high concentration of sugar, colour and aroma. This process goes on for 5 months followed by 25-30 days maceration in oak. The wine is then matured in oak for 5 years.
