Truffle

Tuber melanosporum Vittad

It is commonly known as the black truffle, Perigord or tartufo nero pregiato and is the most valued truffle in Spain and France where it is called “the black diamond of the kitchen”. Its color is blackish or gray with shades of violet. It is irregular in shape and looks like a lump of coal. The weight varies from about 20 g to 300 g. Its skin is very thin and covered with warts. The body is fleshy and compact, more whitish near the skin and grayish toward the center where it eventually becomes purple brown. It has an intense and pungent odor and a pleasant but slightly bitter taste. The harvest period depends on the climate and takes place from late fall throughout the winter months.

Tuber aestivum Vittad or Summer truffle

As its name suggests, the period of growth spans from summer to the beginning of autumn. This fungus has a round shape with irregularities. It is entirely covered by angular warts that differentiate it from the others. Its color is blackish brown and the flesh is firm. The smell is intense and aromatic and it has a distinctive flavor resembling nuts. The summer truffle is considered to be of a good quality and is also suitable for the same uses as the black one, but with the difference that it is available not only during the season, but throughout the year, whether preserved in some liquor or in its own juice. As you can imagine, the price is much lower.

These two truffle varieties are abundant in the area of El Toro, town located in the region of Alto Palancia of the Castellon province. The municipality, which is the second largest in the region, incorporates two distinct areas. One of them is located in the highlands of Barracas that with an altitude of 1000m approximately represent an extension of the southern plains of Teruel. The other area is located in El Toro mountains, formed as an extension of Javalambre mountains. This mountain range is characterized by high altitudes, with some of its peaks over 1600 meters, making it one of the coldest parts of the Valencian Community.

Some years ago, the land in El Toro was not productive. Truffle growers say that the situation has changed to a great extent together with the landscape. Where once the land hardly produced cereal, there are clusters of oak trees providing about 50 kilograms of black truffle per hectare. It is a good opportunity to revert the depopulation of the Spanish countryside, as many families nowadays live off of this production. In addition, nurserymen have been for years successfully producing seedlings of oak (Quercus ilex), the Portuguese Oak (Quercus faginea), hazel (Corylus avellana) and the kermes oak (Quercus coccifera); all of which form micorrhizas with the black truffle (combined structures formed by fungus and tree roots are called mycorrhizas). It has been opted for plantation because the collection of wild truffles has recently significantly diminished; naturally grown truffles barely produce any fruit. The rains of late August and early September are crucial for a good year to come in terms of harvest in the truffle areas of the eastern half of Spain.
