"We produce the RISERVA only from that old vines and use submerged cap maceration for 80 – 90 days.
We then age the wine in large oak barrels for many years, sometimes twice as long as the same wine from the same appellation that is not classified Riserva. This allows the maximum expression of the vineyard in the finished wine.
The RISERVA is released into the marketplace 10 – 15 years after the vintage in a very small quantity, often only a few hundred bottles." - Roagna
