Aragon, in northeastern Spain, has experienced remarkable growth in the production of black truffle (Tuber melanosporum), surpassing France and consolidating its position as the world’s largest producer of this prized fungus. This development has transformed both the agricultural landscape of Aragon and the rural economy, providing employment opportunities and contributing to the fixation of the population in areas that previously faced depopulation.
Traditionally, France had been the largest producer of black truffles, but Aragon has taken the lead, producing more than 25% of the world’s production. The region generates more than half of Spain’s production, consolidating its position as the world’s largest producer of Tuber melanosporum. This leadership is not only a source of pride for Aragon, but also strengthens its competitiveness in international markets.

An economic engine for rural development
In 2023, Aragon exported black truffle worth 34.6 million euros, a significant figure that highlights the importance of this sector for the local economy. Despite a reduction in the volume produced, with Teruel reaching 24.9 tons, high prices kept the value of exports stable. Teruel, in particular, has emerged as one of the most important areas, producing almost half of the total value exported.
Key production areas cover more than 10,000 hectares and are located mainly in the Pre-Pyrenees of Huesca, the Sierra de Gúdar Javalambre in Teruel, and the Moncayo in Zaragoza. These areas offer ideal conditions, with a dry climate and limestone soils, for truffle cultivation, contributing to the revitalization of rural communities and creating employment in various areas linked to truffle growing.
A luxury export product
60% of the truffle produced in Teruel is exported to France, which for years was the world’s leading producer. However, the market has diversified. France alone accounts for 28% of total Spanish black truffle imports, with other key markets in Italy, Belgium, Germany, Denmark and the United Kingdom. This increase in European demand underlines the prestige that the Aragonese black truffle has achieved in international markets.
Unfortunately, the success of truffle farming in Aragon has not been without challenges. In the markets, where demand is high, fraud lurks in the form of confusion between different truffle varieties. Along with the authentic Tuber melanosporum -recognized for its exceptional flavor and aroma-, the second qualityTuber brumale, which is in season at the same time, is also marketed.
The price difference between the two is significant: while Tuber melanosporum can reach between 900 and 1,000 euros per kilo, Tuber brumale is priced at around 400 euros, depending on the time of the season.
Identifying the Truffle: A Complex World
Distinguishing between the different truffle varieties is no easy task. To identify black truffles, three aspects must be observed: the rough layer or peridium that covers them, their gleba or internal mass, and the irregular white veins or veins that run through them in a capricious way.
Tuber melanosporum has a large number of fine, radial veins that open towards the surface, while Tuber brumale has a smaller number of veins, but thicker ones. Other varieties that are often confused are Tuber indicum, which gives itself away by its whitish coating, similar to washed jeans, and Tuber himalayensis, whose texture is more rubbery to the touch, with veins that branch inside the gleba without pointing outward. “It is an extremely complex world.
Trufficulture in Aragon has evolved significantly in recent years thanks to collaboration between scientists and truffle growers. The use of advanced technologies, such as precision irrigation systems, has made it possible to improve both the quality and stability of production, ensuring that prices remain competitive and that the added value stays in the region.
This technification has also boosted job creation in specialized nurseries, companies dedicated to the installation of irrigation systems and in the training of truffle dogs, which are essential for harvesting. This technological boom has consolidated Aragon’s position as a leader in black truffle production, ensuring a quality that translates into international prestige.
Socioeconomic impact: a boost to the rural economy
The socioeconomic impact of truffle farming in Aragon is undeniable. Black truffle production has created a value chain that has revitalized rural economies. From nurseries to processing companies and the training of truffle dogs, this sector has generated employment in several areas and has contributed significantly to the welfare of rural populations.
Black truffle production has not only improved the economic conditions of these communities, but has also provided a sustainable means of rural development. This has allowed many localities, which previously faced depopulation and lack of opportunities, to find in truffle farming an engine for their future.
The black truffle has gone from being a luxury product to become a fundamental pillar of rural development in Aragon, positioning the region as a world leader in this exclusive market and ensuring its long-term economic sustainability.
