Few words inspire as much admiration in the world of gastronomy as "truffle." But although its aroma is unmistakable and its presence on a plate is associated with luxury, exclusivity, and haute cuisine, many still wonder: what exactly is a truffle?
In this article, we'll take you on a journey to discover the origin, value, and complexity of this subterranean fungus that has conquered palates worldwide. From its biology to its cultural history, including its harvesting, varieties, and culinary uses, we'll answer this question in depth, with a special focus on the black truffle (Tuber melanosporum) , the crown jewel of Sentidos Truferos .
The truffle: more than a fungus, a symbol of haute cuisine
A truffle is a hypogeous fungus, meaning it develops underground. It belongs to the genus Tuber , and its growth is closely linked to the roots of certain trees such as the holm oak, oak, or hazelnut, with which it establishes a symbiotic relationship called mycorrhiza .
For months, this fungus develops in the darkness of the subsoil, absorbing minerals from the surrounding environment and capturing moisture from the soil, until it reaches its point of maturity. What makes it extraordinary is not only its origin, but also its aroma: complex, earthy, enveloping , with nuances reminiscent of the forest, moss, hazelnut, and dampness.
Not all truffles are the same, and not all are edible. Among those that are, only a few achieve high gastronomic and economic value.
The black truffle, the most prized of all
Among all edible varieties, the most prestigious is the black winter truffle , whose scientific name is Tuber melanosporum Vitt. Its dark color, veined interior, and powerful aroma make it a favorite among top chefs and the most discerning gourmets.
This variety is harvested primarily in winter, from mid-November to the end of March, when it reaches its peak ripeness. During this season, you can buy fresh black truffles at specialty shops like Sentidos Truferos, which selects each piece at its perfect point, ready to bring the essence of the earth directly to your plate.

Difference between truffles and other edible mushrooms
Unlike other fungi such as porcini or wild mushrooms that grow above ground, truffles develop underground and do not have a cap or gill shape. This not only makes them more difficult to find, but also requires specific harvesting methods, such as the use of trained truffle dogs that can detect their buried aroma.
Furthermore, truffles don't have a strong flavor on their own. What defines and elevates them is their volatile aroma , which is released when heated or when in contact with fatty ingredients like eggs, cream, or butter. For this reason, truffles aren't cooked like other ingredients: they are sliced, grated, or infused , but rarely subjected to high temperatures.
Where do truffles grow?
The black truffle is native to Europe and is found primarily in areas with temperate climates and calcareous soils. Spain, France, and Italy are the world's leading producers. Specifically, Spain is currently the world's largest producer of black truffles , with regions like Teruel, Soria, Huesca, and Castellón serving as international benchmarks.
At Sentidos Truferos we work with truffle growers who know the land in depth and respect the mushroom's timing, harvesting only those pieces that have reached their maximum expression.
How to harvest a truffle
The truffle is located thanks to the keen sense of smell of a truffle dog, which has been trained to detect its aroma underground. Once the dog marks the exact spot, the truffle hunter carefully digs using a tool called a truffle hoe , taking care not to damage the fungus.
This method requires experience, patience, and a deep connection with the land. Every truffle found is a small victory. If you're interested in learning more about this ancient practice, we invite you to read our article, "Shhh… Black Truffles Wanted ."
Are all truffles the same? Most well-known varieties
No. There are more than 70 species of truffle, but only a few have culinary value. Among them, the following stand out:
- Tuber melanosporum : the authentic black winter truffle.
- Tuber aestivum : summer truffle, more affordable and with a milder aroma.
- Tuber brumale : it resembles melanosporum, but has less value.
- Tuber magnatum : the white truffle of Alba, the most expensive in the world.

What makes a truffle so expensive
The price of a truffle depends on several factors: its natural scarcity, the time it takes to mature (up to 10 years from when a mycorrhizal tree is planted), the difficulty of harvesting it, its fragility, and its short shelf life.
Added to all this is the high demand from the best restaurants and discerning enthusiasts, who value the truffle for what it is: an ingredient that cannot be replicated, with an aroma impossible to match.
