Unlike mushrooms, whose season stretches over weeks, the truffle season is highly precise: some species produce edible fruiting bodies for only eight to twelve weeks per year. If you are offered "fresh" truffles outside these windows, be sceptical — almost invariably it will be frozen stock, a different species under a misleading name, or synthetically flavoured imitations.
What does "current" mean?
Right now it is Summer truffle season (Tuber aestivum). The harvest window normally runs from May – September. Mild, nutty, widespread — the approachable summer truffle.
The seasonal calendar
The overview below shows the peak season (dark) and shoulder season (lighter) of the four culinarily relevant truffle species in Europe. Shoulder seasons are possible but not optimal — aromatic intensity then typically lies 20 to 40 per cent below peak.
Climate, soil, patience
Truffles need calcareous, well-draining soils with a pH between 7.5 and 8.5. They grow within a narrow temperature corridor — too dry and they wither, too wet and they rot. A good truffle plantation produces no earlier than eight years in, and full yields only after fifteen. More on this under Truffle cultivation.

Seasonal windows in detail
Spring — a pause
March to April is Europe's leanest truffle period. The Périgord season is winding down and the summer truffle has not yet begun. Anyone buying fresh truffles in these months is buying either the last, aromatically faded Périgord stones, or paying a premium for very early harvested summer truffles — usually neither is ideal.
Summer — the Aestivum
May marks the start of the summer truffle season. It is the longest and most productive season of all — running through September. Anyone cooking with truffles for the first time should start here: affordable, widely available, mild in aroma, forgiving of mistakes.
Autumn — the queen
October opens the shortest, most expensive and most prestigious season: that of the white Alba truffle. The Burgundy season runs in parallel. For those willing to travel: late October to mid-November is when the Alba truffle market is at its peak.
Winter — the Périgord
December opens the Périgord season — the classic season of French haute cuisine. Sauce Périgueux, Tournedos Rossini, truffled Bresse chicken — all winter dishes. The season runs through March, peaking in January.
Freshness beats species. A two-day-old summer truffle is better than a week-old Périgord.
In practice
Anyone who wants to cook with truffles year-round plans purchases along these seasons. Tagliatelle and carpaccio with Aestivum in summer, white Alba over tagliolini in late autumn, classic French Périgord dishes in winter. More on preparation under Storage, and on buying under Where to buy truffles.
