Vernaccia di Serrapetrona DOCG

One of Italy’s most eccentric wines — a sparkling red made from the Vernaccia Nera grape (entirely distinct from the white Vernaccia di San Gimignano) in the remote Apennine foothills of Serrapetrona (Macerata province, Marche). It holds the distinction of being the only DOCG in Italy that requires three separate fermentations.

The Triple Fermentation The process is unique: a portion of the grapes (at least 40%) is harvested and air-dried on racks for several months, concentrating sugars. These dried grapes are then fermented together with fresh grapes from the same vintage. The wine is fermented a second time to create the base, then re-fermented a third time in the bottle or tank to develop the bubbles. The result is a red sparkling wine of deep ruby color, dense foam, and complex aromatics.

The Wine Available in both secco (dry) and dolce (sweet) styles. The character is unlike any other wine: dark wild berries, black cherry, dried violet, black pepper, cinnamon, and a characteristic earthy, almost smoky finish from the drying process. The sweetness in the dolce version is balanced by the grape’s natural acidity and tannin.

The Critical Take Impossible to categorize, difficult to find, and completely worth the effort. A historic oddity that defies every assumption about Italian wine categories.

Why Three Fermentations The sequence sounds like a curiosity and is actually a solution. A dried-grape must is very high in sugar and stalls easily; a fresh must ferments cleanly but gives nothing to work with. Serrapetrona’s method uses one to feed the other — the fresh wine carries the fermentation, the dried portion supplies sugar, colour and aromatics, and the final refermentation puts the bubble in. Nothing else in the Italian rulebook is built this way, and it exists because somebody solved a local problem locally rather than importing a method.

A Grape That Exists Here The black variety behind this wine is grown essentially nowhere else and is unrelated to the white grape of San Gimignano despite the shared name — the word simply meant a local wine in medieval usage and was attached to a great many unrelated varieties across Italy. It is thick-skinned, tannic and late, which is why the drying suits it and why nobody has been tempted to plant it anywhere easier.

Serrapetrona The commune is small, upland and remote, on the shoulder of the Apennines above Lake Caccamo in the province of Macerata, and the denomination barely extends past it. The DOCG came in 2004. Production runs to a few hundred thousand bottles at most, and a large share of that never leaves the Marche.

At the Table The dry version is a genuine partner for cured meats and hard cheese; the sweet belongs with dried figs, almond pastry, or chocolate. Serve both cool, 12–14°C.
