Nebbiolo
is a late-ripening grape that is responsible for great wines of
Piedmont, Barolo, and Barbaresco. Notoriously difficult to cultivate,
Nebbiolo tends to be planted in the warmest hillside sites, where
drainage is excellent. The biggest challenge to makers of Nebbiolo is in
managing the tannic structure of the grape while bringing out the
wonderful aromatic complexities inherent to the variety. While the style
of Barolo and Barbaresco has moved away from the hard, tannic, closed
wines of the past, the best of these wines still benefit from 7-10 years
of aging.
