The bulk of truffle oil on the market is made with a synthetic ingredient, as are many other truffle products. However, alcohol is now being used to carry the truffle flavour without the need for synthetic flavourings. The first truffle vodka, Black Moth Vodka, is a natural vodka infused with black Périgord truffles (Tuber melanosporum). Although primarily used as a spirit in its own right and mixed in a range of cocktails, truffle vodka is also used by various chefs to flavour dishes by evaporating the alcohol through cooking whilst retaining the truffle aroma.[38]

Truffle vodka

Truffle oil is used as a lower-cost and convenient substitute for truffles, to provide flavoring, or to enhance the flavor and aroma of truffles in cooking. Most "truffle oil", however, does not contain any truffles.[37] The vast majority is olive oil which has been artificially flavoured using a synthetic agent such as 2,4-dithiapentane.[37]

Truffle oil

While in the past chefs used to peel truffles, in modern times, most restaurants brush the truffle carefully and shave it or dice it with the skin on so as to make the most of this valuable ingredient. A few restaurants in Switzerland still stamp out circular discs of truffle flesh and use the skins for sauces.

The flavor of black truffles is far less pungent and more refined than that of white truffles. Their strong flavor is often described as syrupy sweet. Black truffles also are used for producing truffle salt and truffle honey.

White truffles are generally served raw, and shaved over steaming buttered pasta, salads, or fried eggs. White or black paper-thin truffle slices may be inserted into meats, under the skins of roasted fowl, in foie gras preparations, in pâtés, or in stuffings. Some speciality cheeses contain truffles, as well.

Because of their high price[36] and their pungent aroma, truffles are used sparingly. Supplies can be found commercially as unadulterated fresh produce or preserved, typically in a light brine.

Culinary use

In Italy, the use of the pig to hunt truffles has been prohibited since 1985 because of damage caused by animals to truffle's mycelia during the digging that dropped the production rate of the area for some years.

The female pig's natural truffle-seeking, as well as her usual intent to eat the truffle, is due to a compound within the truffle similar to androstenol, the sex pheromone of boar saliva, to which the sow is keenly attracted.

New Zealand's first burgundy truffle was found in July 2012 at a Waipara truffle farm. It weighed 330 g, and was found by Rosie, the farm owner's beagle.[34]

In June 2010, Tasmanian growers Michael and Gwynneth Williams harvested Australia's largest truffle from their property at Myrtle Bank, near Launceston. It weighed in at 1.084 kilograms (2 lb 6.2 oz).[32] Mrs. Williams told ABC Radio in Australia[33] that it is valued at about A$1,500 per kg.

In 1999, the first Australian truffles were harvested in Tasmania,[31] the result of eight years of work. Trees were inoculated with the truffle fungus in the hope of creating a local truffle industry. Their success and the value of the resulting truffles has encouraged a small industry to develop. A Western Australian venture, The Wine and Truffle Company, had its first harvest in 2004, and in 2005 they unearthed a 1-kg (2.2-lb) truffle. In 2008, an estimated 600 kilograms (1,300 lb) of truffles were removed from the rich ground of Manjimup. Each year, The Wine and Truffle Company has expanded its production, moving into the colder regions of Victoria and New South Wales.

The first black truffles (Tuber melanosporum) to be produced in the Southern Hemisphere were harvested in Gisborne, New Zealand in 1993.[30]

In New Zealand and Australia

In the last 30 years, new attempts for mass production of truffles have been started. Eighty percent of the truffles now produced in France come from specially planted truffle groves. Nonetheless, production has yet to recover its 1900s peaks. Local farmers are opposed to a return of mass production, which would decrease the price of truffles. There are now truffle-growing areas in the United Kingdom, United States, Spain, Sweden, New Zealand, Australia, and Chile.

In the 20th century, however, with the growing industrialization of France and the subsequent rural exodus, many of these truffle fields (champs truffiers or truffières) returned to wilderness. The First World War also dealt a serious blow to the French countryside, killing 20% or more of the male working force. As a consequence, newly acquired techniques of trufficulture were lost. Also, between the two world wars, the truffle groves planted in the 19th century stopped being productive. (The average life cycle of a truffle-producing tree is 30 years.) Consequently, after 1945, the production of truffles plummeted, and the prices have risen dramatically. In 1900, truffles were used by most people, and on many occasions. Today, they are a rare delicacy reserved for the rich, or used on very special occasions.

These successful attempts were met with enthusiasm in southern France, which possessed the sweet limestone soils and dry, hot weather that truffles need to grow. In the late 19th century, an epidemic of phylloxera destroyed many of the vineyards in southern France. Another epidemic destroyed most of the silkworms there, too, making the fields of mulberry trees useless. Thus, large tracts of land were set free for the cultivation of truffles. Thousands of truffle-producing trees were planted, and production reached peaks of hundreds of tonnes at the end of the 19th century. In 1890, there were 75,000 hectares (190,000 acres) of truffle-producing trees.

The experiment was successful: Years later, truffles were found in the soil around the newly grown oak trees. In 1847, Auguste Rousseau of Carpentras (in Vaucluse) planted 7 hectares (17 acres) of oak trees (again from acorns found on the soil around truffle-producing oak trees), and he subsequently obtained large harvests of truffles. He received a prize at the 1855 World's Fair in Paris.[29]

However, truffles can be cultivated.[28] As early as 1808, there were successful attempts to cultivate truffles, known in French as trufficulture. People had long observed that truffles were growing among the roots of certain trees, and in 1808, Joseph Talon, from Apt (département of Vaucluse) in southern France, had the idea of transplanting some seedlings that he'd collected at the foot of oak trees known to host truffles in their root system.

The most learned men have sought to ascertain the secret, and fancied they discovered the seed. Their promises, however, were vain, and no planting was ever followed by a harvest. This perhaps is all right, for as one of the great values of truffles is their dearness, perhaps they would be less highly esteemed if they were cheaper.[1]

Truffles long eluded techniques of domestication, as Jean-Anthelme Brillat-Savarin (1825) noted:


During the Renaissance, truffles regained popularity in Europe and were honoured at the court of King Francis I of France. However, it was not until the 17th century that Western (and in particular French) cuisine abandoned "heavy" oriental spices, and rediscovered the natural flavour of foodstuffs. Truffles were very popular in Parisian markets in the 1780s. They were imported seasonally from truffle grounds, where peasants had long enjoyed their secret. Brillat-Savarin (1825) noted characteristically that they were so expensive they appeared only at the dinner tables of great nobles and kept women. A great delicacy was a truffled turkey.

Renaissance and modern times

According to a hadith narrated by Saeed bin Zaid, Muhammad said that truffles are like manna and that water from truffles "heals eye diseases".[27]

Truffles were rarely used during the Middle Ages. Truffle hunting is mentioned by Bartolomeo Platina, the papal historian, in 1481, when he recorded that the sows of Notza were without equal in hunting truffles, but they should be muzzled to prevent them from eating the prize.[26]

Middle Ages

Italy in the Classical period produced three kinds of truffles: the Tuber melanosporum, the Tuber magnificanus and the Tuber magnatum. The Romans, however, only used the terfez (Terfezia bouderi), a fungus of similar appearance, which the Romans called truffles, and which is sometimes called "desert truffle". Terfez used in Rome came from Lesbos, Carthage, and especially Libya, where the coastal climate was less dry in ancient times.[24] Their substance is pale, tinged with rose. Unlike truffles, terfez have no taste of their own. The Romans used the terfez as a carrier of flavour, because the terfez have the property to absorb surrounding flavours. Indeed, Ancient Roman cuisine used many spices and flavours, and terfez were perfect in that context.

The first mention of truffles appears in the inscriptions of the neo-Sumerians regarding their Amorite enemy's eating habits (Third Dynasty of Ur, 20th century BCE)[25] and later in writings of Theophrastus in the fourth century BCE. In classical times, their origins were a mystery that challenged many; Plutarch and others thought them to be the result of lightning, warmth and water in the soil, while Juvenal thought thunder and rain to be instrumental in their origin. Cicero deemed them children of the earth, while Dioscorides thought they were tuberous roots.[24]



The term "truffle" has been applied to several other genera of similar underground fungi. The genera Terfezia and Tirmania of the family Terfeziaceae are known as the "desert truffles" of Africa and the Middle East. "Hart's truffle" is a name for Elaphomycetaceae. Pisolithus tinctorius, which was historically eaten in parts of Germany, is sometimes called "Bohemian truffle".[24]

Truffle-like species

The "pecan truffle" (Tuber lyonii)[21] syn. texense[22] is found in the Southern United States, usually associated with pecan trees. Chefs who have experimented with them agree "they are very good and have potential as a food commodity".[23] Although pecan farmers used to find them along with pecans and discard them, considering them a nuisance, they sell for about $100 a pound and have been used in some gourmet restaurants.

A less common truffle is "garlic truffle" (Tuber macrosporum). In the U.S. Pacific Northwest, several species of truffle are harvested both recreationally and commercially, most notably, the "Oregon white truffles", Tuber oregonense and Tuber gibbosum.

Other species

The black summer truffle (Tuber aestivum) is found across Europe and is prized for its culinary value. Burgundy truffles (Tuber uncinatum) are harvested in autumn until December and have aromatic flesh of a darker colour.

Summer or burgundy truffle

The black truffle or black Périgord truffle (Tuber melanosporum), the second-most commercially valuable species, is named after the Périgord region in France and grows with oak and hazelnut trees. Black truffles are harvested in late autumn and winter.[13] The genome sequence of the black truffle was published in March 2010.[20]

The "whitish truffle" (Tuber borchii) is a similar species found in Tuscany, Abruzzo, Romagna, Umbria, the Marche and Molise. It is not as aromatic as those from Piedmont, although those from Città di Castello come quite close.[13]

Whitish truffle

A variety of white truffle (Tuber magnatum pico) is found in other parts of northern and central Italy, but is as aromatic as those from Piedmont.[13]

In December 2014, a White Alba’s Truffle weighing in at 4.16 pounds or 1.89 kilos was unearthed in the Umbrian region of Italy by the Balestra Family of Sabatino. It was auctioned at Sotheby’s in New York.[17] While some had expected it to sell for $1 million,[18] it was sold for $61,000 to a Taiwanese buyer.[19]

The record price paid for a single white truffle was set in December 2007, when Macau casino owner Stanley Ho paid $330,000 (£165,000) for a specimen weighing 1.5 kilograms (3.3 lb), discovered by Luciano Savini and his dog Rocco. One of the largest truffles found in decades, it was unearthed near Pisa, Italy, and sold at an auction held simultaneously in Macau, Hong Kong, and Florence.[16] This record was then matched on November 27, 2010 when Ho again paid $330,000 for a pair of white truffles, including one weighing nearly a kilogram.

In 1999, Giancarlo Zigante and his dog Diana found one of the largest truffles in the world near Buje, Croatia. The truffle weighed 1.31 kilograms (2 lb 14 oz) and has entered the Guinness Book of Records.[15]

The "white truffle" or "trifola d'Alba Madonna" (Tuber magnatum) is found mainly in the Langhe and Montferrat areas[9] of the Piedmont region in northern Italy and, most famously, in the countryside around the cities of Alba and Asti;[10] in Italy it can also be found in Molise, Abruzzo, and in the hills around San Miniato, in Tuscany. It is also found on the Istria peninsula, in Croatia in the Motovun forest along the Mirna river,[11] and in Slovenia along the Dragonja and Rizana river,[12] as well as in the Drome area in France. Growing symbiotically with oak, hazel, poplar and beech and fruiting in autumn, they can reach 12 cm (5 in) diameter and 500 g, though are usually much smaller. The flesh is pale cream or brown with white marbling.[13] Italian white truffles are very highly esteemed (illustration, left) and are the most valuable on the market: The white truffle market in Alba is busiest in the months of October and November when the Fiera del Tartufo (truffle fair) takes place. In 2001, the Tuber magnatum truffles sold for between $1000–$2200 per pound ($2000–$4500 per kg);[14] as of December 2009 they were being sold at $14,203.50 per kilogram.

The phylogeny and biogeography of truffles was investigated in 2008[7] using internal transcribed spacers (ITS) of nuclear DNA with five major clades (Aestivum, Excavatum, Rufum, Melanosporum and Puberulum); this was later improved and expanded in 2010 using large subunits (LSU) of mitochondrial DNA to nine major clades. The Magnatum and Macrosporum clades were distinguished as distinct from the Aestivum clade. The Gibbosum clade was resolved as distinct from all other clades, and the Spinoreticulatum clade was separated from the Rufum clade.[8]


The mycelia of truffles form symbiotic, mycorrhizal relationships with the roots of several tree species including beech, poplar, oak, birch, hornbeam, hazel, and pine.[3][4] They prefer argillaceous or calcareous soils that are well drained and neutral or alkaline.[5][6] Truffles fruit throughout the year, depending on the species and can be found buried between the leaf litter and the soil.


The origin of the word truffle appears to be the Latin term tūber, meaning "swelling" or "lump", which became tufer- and gave rise to the various European terms: Italian tartufo, French truffe, Spanish trufa, Danish trøffel, German Trüffel, Swedish tryffel, Dutch truffel, Polish trufla, Croatian tartuf / тартуф. In Portuguese, the words trufa and túbera are synonyms, the latter closer to the Latin term. The German word Kartoffel ("potato") is derived from the Italian term for truffle because of superficial similarities.[2]
