White Truffle vs Black Truffle: The Tuscany Species Compared

Name, Season and Price Level

The legal windows come from the species-by-species calendar attributed to Legge Regionale 2 agosto 2023, n. 36, the current Tuscan truffle law. The price levels are broad retail brackets, and the detailed euro figures per kilo, season by season, live on the dedicated white truffle price page rather than here. Seasons overlap heavily in autumn, which is why an October hunt can realistically meet more than one species in the same wood.

Collection itself is permitted only during daylight hours set month by month on solar time, roughly 7:00 to 18:00 in January widening to about 4:00 to 21:00 in June.

Two Minor Species on the Calendar

Operator calendars in Tuscany also list two narrower-market species. Tuber macrosporum appears with its own window, and a musk-scented variant of the winter black truffle, Tuber brumale var. moschatum, has its own too. You are unlikely to meet either on a bookable hunt, but they matter if you shop a fair stall, where a vendor may legally sell whatever is in season that week.

How to Recognise It

Tuber magnatum, sold in the trade as tartufo bianco pregiato, is the most valuable of the Tuscan truffles. Its skin, the peridium, is smooth and ochre to pale yellow, with none of the warts you see on black species. Cut it open and the flesh is marbled pinkish brown to pale brown with fine white veins.

The smell is the real identifier: a strong mix of garlic, fermented cheese and gas, a scent that has no black-truffle equivalent. The record for the species is Tuscan. On the night of 26 October 1954, hunter Arturo Gallerini and his dog Parigi found a white truffle near San Miniato weighing 2,520 grams, long cited as the largest ever, and it was sent to US President Dwight D. Eisenhower.

Where and When It Grows

The white truffle grows across a broad belt of Tuscan hill country, from the Lower Valdarno through the Sanminiatesi hills, Valdera, the Volterrano, the Chianti hills, Valdelsa, Val d'Arbia and the Crete Senesi, into parts of the Val di Chiana and Val di Paglia. The older regional law recognised five denominated white-truffle zones: Casentino, Colline Sanminiatesi, Mugello, Val Tiberina and Crete Senesi. The legal season runs 1 October to 15 January across the whole region, the shortest window of the main species and the reason an autumn booking matters.

Full month-by-month detail is on the season calendar page.

How It Is Eaten

White truffle is never cooked. Heat destroys the aroma that makes it expensive, so the whole tuber is shaved raw over the plate at the table, over tagliolini, risotto or a fried egg. This is also why a white truffle must be fresh and why it commands the top price: the value sits entirely in a volatile scent that fades within days.

On a hunt like the San Miniato experience with lunch, whatever the group finds goes straight onto the lunch table shaved raw, which is the most honest way to taste it.

Tuber melanosporum, the Nero Pregiato

Known in Tuscany as the black winter truffle or tartufo nero di Norcia and Périgord type, this is the king of the black side. The skin is black and finely warted. The ripe flesh is blackish with a reddish or purple-black tint and fine white veins that darken as it matures.

The aroma is earthy with a slightly chocolatey note, far gentler than magnatum. Its legal Tuscan season runs 15 November to 15 March, so it peaks when the white truffle is finishing. Retail prices have run roughly 350 to €600 per kilo, a fraction of the white.

Tuber aestivum, the Scorzone or Summer Truffle

The scorzone gets its Italian name from its coarse, dark, pyramid-warted skin. The ripe flesh is pale brown to hazelnut with fine white veins that stay white even at maturity, unlike melanosporum's darkening veins. The aroma is mild, described as leavened bread or flour with a peppery, hazelnut note.

This is the truffle a summer visitor will find, with a legal window of 1 June to 31 August and a second window of 1 October to 30 November. It is the least expensive of the regularly sold Tuscan truffles, at roughly 100 to €350 per kilo, which makes it the entry point for anyone buying their first tuber at a market stall.

Tuber uncinatum, the Autumn Form

Tuscan and Italian regulation treats Tuber uncinato, the uncinato, as the autumn-ripening form of the summer truffle. It shares the look of Tuber aestivum but is harvested later, with a legal season of 1 October to 15 January, exactly the same window as the prized white truffle. Aroma-wise it is stronger than a summer scorzone because it ripens in cooler, wetter ground.

It often appears in the same basket as a magnatum find in late autumn.

Tuber brumale, the Winter Black

The tartufo nero d'inverno is a lower-value look-alike of the nero pregiato, with the same dark warty skin, and markets do occasionally confuse the two. The cut flesh gives it away: grey-brown to grey-blackish, with few, wide whitish or beige veins rather than the fine veining of melanosporum. Its season is 15 January to 15 April, so it overlaps the tail of the white truffle window and the whole of the nero pregiato season.

Price sits at the low end of the black range.

Why It Is Not a Tartufo Bianco Pregiato

The bianchetto, also called marzuolo because it ripens toward March, is a lighter, less prized white truffle. Its legal season is 15 January to 15 April, shared with Tuber brumale, so it fills the late-winter gap when magnatum and melanosporum are finished or finishing. Commercially it is less sought after than either the white truffle or the nero pregiato, and its price reflects that.

One biological quirk matters: it fruits earlier than other species in young plantations, appearing in stands as young as four years old under pine. If a restaurant in March offers white truffle, ask which one, because the honest answer is usually bianchetto at a very different price.

White Truffle, Raw Only

Tuber magnatum and bianchetto are both eaten raw, shaved thinly at the table over a finished dish. The white truffle's aroma compounds are fragile and largely disappear with heat, so Tuscan kitchens treat it as a seasoning, not an ingredient. Classic carriers are egg-based and neutral: tagliolini, risotto, a soft scrambled egg or a plain fonduta.

A few grams per plate is enough, which matters when the raw material runs into the thousands of euros per kilo.

Black Truffle, Gentle Heat Welcomed

Can you eat black truffles raw? Yes, and thin shavings over a finished dish work for Tuber melanosporum too. But unlike the white, the black winter truffle keeps and even develops its aroma under gentle cooking, so it goes into sauces, butter, omelettes and slow-cooked meats.

The scorzone, with its milder flour-and-hazelnut scent, is usually sliced thin raw or lightly warmed, since strong heat would erase what little aroma it has. This is why menus in winter cook the black and never cook the white.

A Word on Truffle Oil

Chefs tend to dislike truffle oil, and the reason is simple. Most commercial truffle oil is not made from real truffle but from synthetic aroma compounds, so it carries none of the complexity of a magnatum or a melanosporum and flattens everything it touches into a single chemical note. None of the species pages in the regional or market sources describe truffle oil as a product of the Tuscan harvest.

If you want the real taste, buy fresh tuber in season or eat it shaved on a hunt, and skip the bottle.

Broad Brackets by Species

The market splits cleanly into three tiers. The white truffle sits alone at the top: San Miniato quoted around €2,000 per kilo at the start of a recent season in October, rising to a base of about €3,000 per kilo by November, and in the lean previous season prices went above €4,000 per kilo after dry weather roughly halved the harvestable quantity compared with five or six years earlier. The nero pregiato occupies the middle tier at roughly 350 to €600 per kilo retail.

The scorzone, uncinato, brumale and bianchetto fill the low tier, with the scorzone at roughly 100 to €350 per kilo. For the full picture, including the Alba auction comparison, see white truffle prices explained.

What That Means on a Hunt

A hunt is a demonstration in the woods with a licensed hunter and trained dogs, and nobody can promise a find, especially of the white truffle. Anything dug up belongs to the hunter and the landholder, not the guest, so the price you pay covers the walk and the meal, not the truffle. Experiences differ in what follows the walk: the San Gimignano hunt with lunch and wine tasting is priced at $218 for 3 hours, while a Siena hunt with tasting runs $163.72 for 2 hours without lunch.

Both are honest ways to meet the dogs, and both find whatever species is legally in season on the day.
