Where are most truffles found?
Europe remains the epicentre of truffle production, particularly for the high-value black and white truffles. However, regions like Australia and North America are increasingly important in meeting global demand. France, Italy, and Spain dominate truffle production in Europe, with Italy particularly excelling in white truffles and France and Spain leading in black truffle cultivation.
In Europe, the top truffle-producing regions are concentrated in areas with the ideal combination of climate, soil, and host trees. These regions are renowned for their quality truffles, including black, white, and summer varieties. Here are the leading areas:

How are truffles found?
Truffles are found using traditional methods, trained animals, and careful observation of natural indicators. The most common and effective approach involves using truffle-hunting dogs. These dogs are specially trained to detect the unique and intense aroma of truffles, which grow underground near the roots of specific trees, such as oaks and hazelnuts. Once the dog identifies the scent, it signals the location by lightly digging or pointing its nose, and the truffle hunter carefully extracts the fungi with a small spade or knife to avoid damage.
Pigs were often used for truffle hunting because they are naturally attracted to the smell of truffles. However, dogs have primarily replaced them due to their tendency to eat the truffles they find and the challenges associated with handling them in the field. Truffle hunters also rely on their knowledge of the environment, searching for areas with the right types of trees and soil conditions. Signs such as disturbed soil or insects attracted to truffle aroma can also indicate where truffles may grow.
In cultivated truffle orchards, where trees are inoculated with truffle spores, the process is more targeted, as the locations of the potential truffle-producing areas are predefined. In some experimental settings, technologies like ground-penetrating radar have been used to detect truffles underground, but this is not a common practice due to its complexity and cost.
Finding truffles requires patience, skill, and a deep understanding of the natural habitat where these prized fungi thrive. Sustainable and ethical harvesting practices are also crucial to preserve truffle ecosystems for future generations.
Which are the most expensive truffles?
The White truffle (Tuber magnatum) is the most expensive, particularly those from the Alba region in Italy. They command the highest prices due to their rarity, intense aroma, and unmatched culinary value. Found primarily in the forests of northern Italy, especially in Piedmont, these truffles grow naturally and are harvested during a short season in the autumn months. Their scarcity and difficulty locating them, combined with their highly prized flavour, make them extraordinarily valuable.
Another highly expensive truffle is the black winter truffle (Tuber melanosporum), also known as the Périgord truffle. Found in regions like France, Spain, and Italy, this truffle is revered for its earthy and aromatic qualities, making it a staple in gourmet cuisine. While not as costly as white truffles, black winter truffles still fetch significant prices in the market, particularly during peak seasons.
Occasionally, exceptionally large or rare truffles of either type can sell for exorbitant prices at auctions or speciality markets, with some specimens fetching tens or hundreds of thousands of Euros. These record-breaking truffles are often purchased by luxury restaurants or private collectors, further cementing their status as one of the most coveted culinary treasures in the world.
Where can you buy fresh truffles?
Fresh truffles can be purchased from various sources depending on the region and season. In truffle-producing areas, local markets and seasonal festivals are excellent places to find fresh truffles sold directly by hunters or vendors. For example, events like the Alba White Truffle Fair in Italy or the Richerenches Truffle Market in France are renowned for their selection of high-quality truffles.
Gourmet shops and delicatessens in major cities also stock fresh truffles during harvest, often alongside truffle-infused products. Online retailers, such as Urbani Truffles, Sabatino Tartufi, and Gourmet Food Store, provide the convenience of having fresh truffles delivered directly to your door, with detailed storage and usage instructions.
Visiting truffle farms can be an ideal way to buy fresh truffles in regions with established truffle farming. These farms often sell their harvest on-site and may even offer customers truffle hunting experiences. Some restaurants and chefs also sell fresh truffles to their patrons during the season, ensuring top quality through trusted suppliers.
For rare or particularly large truffles, speciality auctions, such as those held during the Alba White Truffle Fair, provide a platform to acquire unique specimens. Additionally, farmers’ markets in regions like Piedmont, Tuscany, Périgord, or Istria frequently feature fresh truffles during their seasons, often sold by local producers.
When purchasing fresh truffles, it is essential to consider seasonality, as they are only available at certain times of the year. A fresh truffle should be firm and aromatic, free from soft spots or signs of rot. Since they are highly perishable, they should be used promptly or stored carefully to preserve their unique flavour and aroma.
