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. It has never been farmed successfully, which is a large part of why it costs what it does and why availability swings so much from one week to the next. 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 only when a seller uses it to imply a specific origin or a specific quality tier that isn't backed up by anything. A truffle marketed as "Alba" but sold in July is not white truffle at all, since the season runs from October to December — it's almost always bianchetto, a related but much milder spring species. A truffle marketed as "Alba" with no Latin name, no harvest date and no stated region on the listing is a red flag regardless of the season, because a supplier with nothing to hide usually puts that information in writing without being asked.
Reading a listing: what the claim actually promises
|

What it actually tells you |
What to check |
|
"Alba white truffle" |
brand name for the species, not proof of origin |
ask for the Latin name and region |
|
"Tuber magnatum pico" |
scientific name, the real identifier |
confirm harvest date is within season |
|
"fresh white truffle" (no season stated, sold outside Oct–Dec) |
very likely bianchetto or another species |
treat as a different product |
|
"Piedmont" / "Istria" / "Le Marche" named directly |
supplier is disclosing actual origin |
a good sign, not a downgrade |
|
no Latin name, no date, no region anywhere |

avoid or ask before ordering |
What to check before buying
Ignore the word Alba entirely and look for three things instead: the Latin name Tuber magnatum on the listing, a harvest date within the October to December window, and a supplier willing to state the general region the truffle came from. A supplier confident in their sourcing will say which one, whether that's Piedmont, Le Marche, Tuscany or Istria.

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? Check the season. Genuine Tuber magnatum is only available fresh from October to December. Anything sold as fresh white truffle outside that window is a different species.
