Near Mas Saint Antoine, across the Rhône, lies one of France’s most prestigious gastronomic terroirs: the Tricastin. This region straddling Drôme Provençale and Vaucluse is France’s leading truffle region — it alone produces about 60% of national black truffle.
Every winter, from November to March, the black diamond (Tuber melanosporum) animates the markets, festivals and tables of the territory. It’s a season little known to tourists — most visitors come in summer — and that’s precisely what makes it a treasure to discover.
Tricastin black truffle: what is it?
The Tricastin black truffle is the Tuber melanosporum — exactly the same species as the famous ‘Périgord truffle’. It’s an underground mushroom that develops in symbiosis with the roots of truffle trees, mainly oak, in calcareous soils and Mediterranean climate.
It’s recognized by its powerful, woody and wild aroma, and its black flesh veined with white. In hand, a good black truffle is heavy, dense and firm. The Tricastin also produces the brumale truffle (Tuber brumale), smaller with muskier aromas.
Why the Tricastin?
Black truffle is capricious: it requires calcareous soil, a Mediterranean climate, and above all summer storms (it is born in May and needs water to develop). The Tricastin naturally combines these conditions, making it for centuries the French capital of truffle.

The truffle season: November to March
The harvest of black truffle — the cavage — takes place during winter, from mid-November to late March. But not all periods are equal:
| Period | Truffle quality |
|---|---|
| Mid-November – early December | Start of season, truffles not yet fully mature |
| Mid-December – February | Peak season, ripe and fragrant truffles (the best period) |
| March | End of season, still good quality but declining harvest |
Our tip: the best period is from mid-December to mid-March. Connoisseur’s tip: truffles are often ripest and prices gentler after New Year, when the strong holiday demand has subsided.
Truffle markets: where and when?

The Truffle House of the Tricastin
To understand truffle before buying it, a visit is essential: the Maison de la Truffe et du Tricastin, in Saint-Paul-Trois-Châteaux (rue de la République), about 30 minutes from Mas.
Set in a former bourgeois mansion in the heart of the old town, it unfolds over 7 exhibition rooms all the secrets of Tuber melanosporum: biological cycle, cultivation, cavage, gastronomy. It also houses the Tricastin winemakers’ cellar, where you can taste and buy AOP Grignan-les-Adhémar wines.
- Price: €4.50 adult, €3.50 reduced, free for children, students, jobseekers.
- Visit duration: about 40 minutes (1h in groups).
- Hours: Tuesday to Saturday 10am-12:30pm and 2:30pm-6pm, Sunday 10am-1pm (in summer and mid-December to mid-March). Closed Monday.
- Good tip: during the season, ‘Truffle Discovery Days’ are offered on Saturdays.
Cavage: searching for truffle with dogs
The cavage — the search for truffle — is a fascinating experience. The truffle grower works in a duo with a trained dog that locates, thanks to its sense of smell, the exact location of the truffle underground and scratches the soil to mark it. The grower then carefully extracts the truffle with a hook called a ‘fouji’.
Many Tricastin truffle growers offer visitors the chance to accompany them for a cavage demonstration, followed by a tasting. Ask the Drôme Provençale Tourist Office or the Truffle House for growers offering these outings during your stay.
Buying truffle: our tips
How to choose it well
- Weight: a good truffle is heavy and dense for its size.
- Firmness: it should be firm to the touch, never soft.
- Aroma: it should be powerful, woody, wild.
- Flesh: when cut, the black flesh should be finely veined with white.
- Origin: in controlled markets like Saint-Paul-Trois-Châteaux, truffles are certified.
How to store it
Truffle is a living and fragile product: it breathes and loses its aroma every day. Store it in the refrigerator in an airtight box, wrapped in absorbent paper changed daily. Consume it ideally within 5 to 7 days. Tip: place eggs in the box, their porous shell will become fragrant.
How to enjoy it
Black truffle is enjoyed raw or very lightly heated: too long cooking destroys its aromas. The classics: scrambled eggs, omelette, risotto, fresh pasta, mash. The golden rule: simple, lightly seasoned dishes, to let the truffle express itself. Grate or slice it thinly at the last moment.
Truffle festivals and events
- The Ban des Truffes in Richerenches, the first Saturday of December, marks the official opening of the season.
- The Truffle Omelette Festival in Saint-Paul-Trois-Châteaux, the second weekend of February, is a major popular and gourmet event.
- Truffle masses and truffle dinners punctuate the season across the territory.
