Most people search for "Alba white truffle" without knowing that Alba is a town, not a species. Tuber magnatum is the truffle. Alba is where the biggest fair for it happens to be held, and the name stuck to the product the way "Champagne" stuck to sparkling wine from one region. Once that's clear, most of the confusion around this search clears up with it.
What Alba actually refers to
Alba is a small town in Piedmont, northern Italy, and home to the Fiera Internazionale del Tartufo Bianco d'Alba, the region's white truffle fair, running through October and November since 1928. The fair drew buyers, chefs and dealers from across Europe long before international shipping made fresh truffle a global product, and that history is why the town's name became shorthand for the species itself rather than for one specific harvest location. A truffle from the hills near Asti or from Istria in Croatia can be genuine Tuber magnatum without ever having passed through Alba itself, in the same way most Champagne-style sparkling wine never touches the Champagne region.
So what is Tuber magnatum
Tuber magnatum pico is the scientific name for the species everyone means when they say white truffle or Alba truffle. It grows wild in symbiosis with oak, poplar, willow and lime across Piedmont and neighbouring regions of northern and central Italy, with smaller harvests from Istria and parts of the Balkans. Cultivation has been demonstrated: INRAE reported successful orchard production in France. Buyers should still check the current harvest and lot details rather than assuming availability. Our white truffle season guide covers the harvest window and what drives supply in more detail.
Regions that produce genuine Tuber magnatum
The species isn't confined to one valley, and knowing the range helps make sense of listings that mention a region other than Alba.
Piedmont is the historic core of the trade, centred on the hills around Alba, Asti and Alessandria, and it's the source most buyers picture when they hear the name.
Le Marche and Tuscany, on Italy's central coast, produce truffles with a similar profile, slightly milder in some harvests, and supply a meaningful share of what reaches export markets.
Molise and Umbria contribute smaller but steady harvests, often overlooked because they don't have a fair the size of Alba's.
Istria, in Croatia, has become a serious source in its own right over the past two decades, with terrain close enough to Piedmont's that the truffle is essentially the same species and quality, sold honestly under its own regional name rather than borrowed Italian branding.
None of these regions makes a truffle less authentic. They make it a different harvest of the same species, and a supplier naming the actual region is giving more information, not less.
When "Alba truffle" is misleading
The name becomes a problem when it is used to imply an origin or quality tier that the seller does not disclose. “Alba” is not a substitute for the scientific name, harvest origin or lot information. Fresh Tuber magnatum is associated with autumn and early winter; the Alba Fair gives October 1–January 31 for Piedmont. Calendars vary by region. If a listing appears outside the expected window, ask whether it is fresh magnatum, another species such as bianchetto, or a frozen or preserved product. Season alone does not prove the species.

What to check before buying
Look for the scientific name Tuber magnatum, a stated harvest origin and current lot information. Ask when the truffles were harvested or received and how they have been stored. Region and season help you evaluate a listing, but they do not replace species identification or condition checks. See our fresh truffle buying guide for more detail, then buy fresh white truffles (Tuber magnatum) using the live grade and pack-size selector.
Common questions about Alba truffle vs Tuber magnatum
Is Alba truffle a different species from Tuber magnatum? No. Alba white truffle and Tuber magnatum are the same truffle. Alba is the town most associated with the harvest and its fair, not a separate species or grade.
Does a truffle need to come from Alba itself to be called Alba truffle? No, and most don't. The term is used across the trade for Tuber magnatum from Piedmont and surrounding regions, including Le Marche, Tuscany, Istria and parts of the Balkans.
Why do some Alba truffles cost more than others? Price tracks size, shape and ripeness more than exact town of origin. A large, intact, well-shaped specimen commands a premium regardless of which region it came from.
How do I know I'm buying real Tuber magnatum and not bianchetto? Ask for the scientific name, harvest origin and current lot information. Tuber magnatum and Tuber borchii are different species; appearance or season alone does not authenticate them. Confirm the species and condition with your supplier before ordering.
