Italy produces approximately 70-80% of the world's white truffles and is the world's largest producer of black truffles. The truffle calendar in Italy runs essentially year-round, different varieties peak at different times in different zones, but two moments dominate: October-December in the Langhe hills of Piedmont for the white truffle (Tuber magnatum Pico, the most expensive food by weight in the world), and November-February in Umbria and the Marche for the black Périgord-type truffle (Tuber melanosporum). Understanding this calendar allows visitors to plan specifically to encounter truffles in their natural season rather than in the preserved, processed, or artificially scented form that fills souvenir shops year-round.

The Italian Truffle Calendar
White Truffle Season (Tartufo Bianco): October. December
The white truffle of the Langhe (Tuber magnatum Pico) grows underground in symbiosis with oak, hazel, and linden roots in the specific microclimate of the Piedmont hills around Alba, Asti, and parts of the Marche, Tuscany, and Umbria. The season begins in early October when the first truffles are found. Peaks in October-November when the best specimens are at full aromatic maturity. And tails off in December. The Fiera del Tartufo di Alba (the Alba Truffle Fair, running every weekend in October and November) is the world's most important truffle market, a combination of competitive truffle auction, cookery demonstrations, and general celebration of the truffle economy. White truffle prices fluctuate dramatically by year depending on rainfall. Typical years see prices of €3,000-5,000 per kg for good specimens, with exceptional years reaching €10,000+.
Summer Truffle Season (Tartufo Estivo): May. August
The summer black truffle (Tuber aestivum, or Tuber uncinatum in autumn) grows in the same zones as the winter varieties but at a different depth and with a much more modest aroma. It is the truffle available in summer, when restaurants need to serve truffle dishes to tourists who expect them, but at a fraction of the flavour intensity and cost of the winter varieties. Summer truffle isn't a lesser version of winter truffle. It is a different product that should be priced and presented accordingly. At €200-500 per kg (versus the white truffle's thousands), summer truffle provides genuine truffle flavor at accessible cost.
Black Périgord Truffle Season: November. March
The Tuber melanosporum, the black truffle of the Périgord that is grown commercially in France but in Italy occurs naturally in the Norcia zone of Umbria and in the Marche hills, peaks in December-January when the cold produces the most intensely aromatic specimens. The Mostra Mercato del Tartufo Nero (Norcia, February) and the Rassegna del Tartufo Nero Pregiato (Viterbo, January-February) are the principal fairs. The Norcia black truffle, at €800-1,500 per kg, is significantly more accessible than the white while providing genuine winter truffle character.
Q&A: Truffle Season Italy
Is October the best month for truffles in Italy?
For the white truffle: October and November are the peak months in the Langhe. The first major truffle finds of the season typically occur in late September or early October. The Alba Truffle Fair's weekend markets from the first Saturday in October through the third Sunday in November provide the most complete commercial access to fresh white truffle. For the combined truffle and wine harvest experience (Barolo harvest overlaps with truffle season in October): yes, October is definitively the best month.
What should I actually buy at a truffle fair?
Fresh truffle (tartufo fresco): the most direct product, expensive per gram, needs to be used within 5-7 days. Keep refrigerated wrapped in dry paper towel in a glass jar. The truffle continues to lose aroma rapidly after harvest. Truffle-infused olive oil: quality varies enormously, genuine truffle oil uses real truffle pieces in olive oil. Most commercial truffle oil uses 2,4-dithiapentane, an artificial flavoring compound with a "truffle-like" aroma that isn't related to actual truffle. The tell: ingredient list should include "tartufo" as an actual ingredient, not just "aroma di tartufo." Truffle salt, truffle honey, truffle butter: all genuine if made with real truffle. Useful shelf-stable forms for bringing the flavor home.
