Norcia Truffle: The Prized Black Truffle and Where to Buy It

The Norcia truffle, or prized black truffle (tartufo nero pregiato), is Tuber melanosporum Vittadini. It is a fungus that grows underground, in symbiosis with the roots of oaks, hornbeams, hazels and holm oaks. In the Sibillini Mountains it is harvested in midwinter, according to the regional calendars: in Umbria from December 1 to March 15. The main market is Norcia, so much so that the most common name is tartufo nero di Norcia, Norcia black truffle; on the Ascoli side of the park the best-known place for truffles is Montemonaco. The skin is black and wrinkled, the flesh is dark and laced with fine white veins, and the aroma is delicate and pleasant.

For over seventy years Norcia has held a truffle fair and market that fills the historic center at the end of winter. Its bond with the town, however, is much older: it goes back to the norcini, who for centuries took the “black diamond” to the markets of Rome along with cured meats and processed pork. Today the prized black truffle is bought fresh during the harvest months, while the tradition of processing and preserving it, born in the Valnerina, makes it available in preserved forms as well.

Norcia Truffle: Origin and Characteristics of the Umbria Truffle

The prized black truffle is a hypogeous (underground) fungus of the Ascomycetes class: it develops and ripens underground, linked to the roots of certain plants. The mycologist Carlo Vittadini gave it its scientific name in 1831. Melanosporum comes from Greek and means “black spore”, for the color of its spores. It is also known by the synonym Tuber nigrum Bull.

In Umbria the prized black truffle is a Prodotto Agroalimentare Tradizionale (PAT), an officially listed traditional food product. In the province of Perugia, the production area includes Norcia, Cascia, Preci, Monteleone di Spoleto, Poggiodomo, Scheggino, Sant'Anatolia di Narco, Vallo di Nera, Cerreto di Spoleto, Sellano, Spoleto, Campello sul Clitunno, Castel Ritaldi and Giano dell'Umbria, and in the province of Terni, Stroncone. On the Marche side, the Le Marche truffle is found in Camerino and Visso, in the Monti Sibillini, in Amandola and Montefortino, and in the Ascoli area in Acquasanta Terme, Roccafluvione and Comunanza.

It grows well in limestone soils with a good share of clay. Around Norcia it is found in woods between 400 and 800 meters of altitude. Sizes range from that of a hazelnut to that of an orange. The shape is mostly round, but around Norcia it is often knobbly because of the stony soil.

Three things help recognize it:

  • Skin (peridium): black and wrinkled, with small polygonal warts. Scratching it gently reveals a reddish, rust-like color: truffle hunters use this to tell it apart from similar black truffles.
  • Flesh (gleba): purplish black when the truffle is ripe, with fine white veins that turn reddish in the air and darken when cooked. In unripe specimens the flesh is pale.
  • Aroma and flavor: delicate, pleasant aroma; a flavor that leans toward sweet, so much so that it is also called “tartufo nero dolce”, sweet black truffle.

The same woods of the Sibillini National Park are also home to the white truffle, which is rare and harvested between October and December, and the summer truffle (scorzone estivo), which ripens between June and August. In the traditional Umbrian supply chain, prized black truffles are sorted by hand, washed and then divided into commercial grades: super extra, first choice, second choice, pieces and trimmings.

The History of the Norcia Black Truffle

The Romans already ate truffles and considered them an aphrodisiac. In the 15th century Platina wrote admiringly of the skill of the “sow of Norcia” in finding truffles. In the Norcia area, in fact, truffles were long hunted with sows. In the Renaissance the Umbrian physician Alfonso Ceccarelli wrote the Opusculus de tuberis, which gathered everything then known about this fungus.

The fame of the prized black truffle outside Umbria is due above all to the norcini. They traveled around central Italy to process pork and, in season, also brought truffles with them, especially to Rome. The truffle market and truffle processing in the Valnerina developed at the end of the 19th century. Between the 19th and 20th centuries the Norcia black truffle was already very well known, and one of the first packaging and preserving industries operated in the Valnerina.

In 1951 the first fair devoted to the Norcia black truffle was born, organized by Antonio Bianconi, Gaetano Allegrini and Giuseppe Millefiorini. It was held in the rooms of the Circolo Cittadino, in Palazzo Santoni, along Corso Sertorio. Only local truffles were sold, in wicker baskets marked with their origin: Norcia, Cascia or Preci. The aim was to help farmers by putting truffle diggers in direct contact with consumers, narrowing the gap between the prices set by traders and the very low pay of the gatherers. The first edition took place before Christmas. Over time the fair opened up to other typical products and to traders from everywhere.

Today the event is called Nero Norcia, the truffle festival, and it runs between the last weekend of February and the first weekend of March. On the Marche side, Amandola devotes to the prized black truffle the late-winter edition of “Diamanti a tavola”, a festival of truffles and Sibillini local food products: in 2026 the black truffle edition reached its seventh year, while in November the festival returns with the white truffle. The Associazione Tartufai dei Monti Sibillini, the Sibillini truffle hunters' association, collaborates with the festival.

How to Enjoy the Norcia Truffle

Unlike the white truffle, the prized black truffle holds up well to cooking, and heat releases its aromas better. Cooking must stay brief, though: it is best not to fry or brown it, because too much heat ruins it. It is also good raw, shaved over hot dishes.

The recipe most associated with Norcia is spaghetti alla norcina in its truffle version. There is also a pasta alla norcina with sausage and cream, but the truffle version uses few ingredients, chosen to keep the truffle in the foreground: extra virgin olive oil, garlic and anchovies. For four people, 100 to 120 grams of black truffle are usually needed. The method:

  1. Brush the truffle under a trickle of running water and grate it finely.
  2. Heat the oil over low heat with crushed garlic and the anchovies, stirring until the anchovies dissolve.
  3. Add the truffle over very low heat or with the heat off, so it perfumes the oil without burning.
  4. Toss the al dente spaghetti in the sauce, adding a little cooking water if needed.

The prized black truffle also works on risotto, eggs and meat. Other classic uses are fried eggs, crostini and strangozzi alla spoletina.

For storage, the truffle should not be washed ahead of time: the soil protects it and holds in its aroma. It is wrapped in paper towel, closed in an airtight glass jar and kept in the refrigerator, changing the paper every day because the truffle releases moisture. A fresh truffle is not meant to age: it should be bought at the right ripeness and eaten as soon as possible, generally within about a week.

Where to Buy the Norcia Truffle in the Sibillini Mountains

Fresh prized black truffles are bought during the harvest season, from December to mid-March. Norcia is the main market; on the Ascoli side of the Sibillini the best-known place for truffles is Montemonaco.

The easiest time to find many producers together is Nero Norcia, at the turn of February and March. In the 2026 edition the stalls ran from Porta Romana to Porta Ascolana and, besides truffles, offered cured meats, cheeses, wines and other typical products. In Amandola the “Diamanti a tavola” festival offers a similar opportunity on the Marche side, in late winter. The exact dates are worth checking every year, because they change from one edition to the next.

When buying, a few signs matter. The truffle should be intact, because damaged ones spoil sooner. To the touch it should feel firm and slightly springy: if it is too soft it may be hiding rot, if it is too hard it is drying out. The aroma should be pleasant and aromatic. Lightly scratching the skin should reveal the rust tone typical of the species, and the flesh of a ripe specimen is dark. The commercial grade (super extra, first choice, second choice, pieces, trimmings) helps to understand what is being bought.

Visitors to Norcia can pair the truffle with the local cured meat tradition, described on the page on Prosciutto di Norcia IGP, and with local cheeses such as Sibillini pecorino cheese. The full list is on the page on Sibillini local food products.

Frequently asked questions

How much does the Norcia black truffle cost?

The Norcia black truffle is among the most expensive products on the market, although it costs less than the prized white truffle. The price changes with quality: truffles are divided into super extra, first choice, second choice, pieces and trimmings. It is always worth asking for the grade and checking that the truffle is intact and firm.

Which is better, black or white truffle?

It depends on the use. The prized white truffle (Tuber magnatum) is considered the finest, and the Norcia black comes right after it. Unlike the white, however, the black holds up well to brief cooking, which releases its aromas: that is why it suits hot sauces such as spaghetti alla norcina. Both grow in the Sibillini.

Why does a truffle sometimes taste of nothing?

The prized black truffle only shows its qualities if it is harvested fully ripe: when unripe, its flesh is pale instead of purplish black. It also loses aroma if it ages and dries out, if it is washed before storing or if it stays too long in the refrigerator. Cooking it over too much heat, for example frying it, ruins it.

Where does the Norcia black truffle come from?

The Norcia black truffle grows in the Valnerina and the Spoleto area. In Umbria its recognition as a traditional product covers Norcia, Cascia, Preci, Spoleto and Sellano, among others. It is also found in the Marche: in Visso, Amandola, Montefortino, Montemonaco and other municipalities of the Ascoli area. It is harvested in woods on limestone soils, near oaks, hornbeams, hazels and holm oaks.

What does the Norcia black truffle look like?

The Norcia black truffle is round, often knobbly, and ranges from the size of a hazelnut to that of an orange. The skin is black and wrinkled, with small polygonal warts, and scratching it reveals a rust color. The ripe flesh is purplish black, with fine white veins that turn reddish in the air. The aroma is delicate.

How is the Norcia black truffle used in cooking?

The Norcia black truffle can be used raw, shaved, or cooked briefly, without frying it. The typical recipe is spaghetti alla norcina: grated truffle warmed over very low heat in extra virgin olive oil with garlic and dissolved anchovies. It also suits risotto, fried eggs, crostini, meat and strangozzi alla spoletina.

What is the Norcia black truffle?

It is the common name of the prized black truffle, Tuber melanosporum Vittadini: a fungus that grows underground in symbiosis with the roots of certain trees. It is called “of Norcia” because it is very common in that area and because the town is its main market. In Umbria the harvest runs from December 1 to March 15.

What can you eat and buy made with Norcia black truffle?

The dish to try is spaghetti alla norcina with truffle, oil, garlic and anchovies. In Norcia, during the Nero Norcia fair at the end of winter, fresh truffles and typical products such as cured meats, cheeses and wines are available. When buying fresh truffle, choose one that is intact, firm and fragrant.

Where is the truffle found in Le Marche and the Sibillini National Park?

On the Marche side of the Sibillini Mountains the prized black truffle is found in Camerino and Visso, in Amandola and Montefortino, and in the Ascoli area in Acquasanta Terme, Roccafluvione and Comunanza. On the Ascoli side of the Sibillini National Park the best-known place for truffles is Montemonaco, and Amandola hosts the Diamanti a tavola festival.
