Cailletier Olives (True Niçoise)
The Cailletier is the single olive variety behind the genuine “Niçoise” olive — a small, dual-purpose fruit grown mainly around Nice in the Alpes-Maritimes of south-east France, and across the border in Italian Liguria, where the very same cultivar is known as Taggiasca. When you see a tiny, brown-to-purple-black olive sold as “Niçoise,” that word describes the region and the curing style; the tree itself is almost always Cailletier. It earns its keep twice over: pressed for a mild, sweet oil, and cured whole as a table olive prized far beyond its size.
Where it comes from and what “Niçoise” really means
This is where a lot of shoppers get tripped up, so it is worth being precise. A variety’s name is not the same as a country of origin — and “Niçoise” is not a variety at all. It is a place-and-method label. The fruit is the Cailletier cultivar; “Niçoise” tells you it was grown and cured in the Nice area, where the traditional treatment produces those wrinkled, wine-dark olives you find scattered through a proper salade niçoise.
The Cailletier’s heartland straddles a border. On the French side it dominates the terraced groves of the Alpes-Maritimes, from the hills behind Nice up towards the Roya and Var valleys. Cross into Liguria and you meet what is generally regarded as the same or a very closely related cultivar under the local name Taggiasca, around Taggia and Imperia. Same small fruit, same gentle oil, different flag on the label. So while Nice gives the olive its most famous name, it is fairer to call this a Riviera olive of both France and Italy than to pin it on one country alone.
France recognises the pedigree formally. The Nice growing area carries protected appellations covering the oil, the whole table olive and even the olive paste — the sort of origin protection that ties the name to a defined place and set of practices rather than to any grower who fancies the label. In Italy the Taggiasca side enjoys its own protected-origin status.
Oil and table olive: one tree, two jobs
What makes the Cailletier quietly special is that it does not force a choice between oil and eating. Many groves harvest for both. The stone is on the large side relative to the flesh, which you might think would hurt oil yield — yet it still presses out a respectable roughly 20–25% of oil by weight. That oil is the calling card: soft, sweet, low in bitterness and pepper, with almond and light-fruit notes. It is the kind of oil often recommended to people just finding their feet with single-variety oils, because there is nothing aggressive to get past. Finishing fish, dressing tender leaves, folding into aïoli — that gentleness is the point.
As a table olive the Cailletier is small and, frankly, more stone than most people expect — but the flavour-to-flesh ratio wins people over. Cured the Nice way, it turns nutty, faintly bitter and savoury, holding up beautifully in tapenade, in pissaladière, alongside anchovies, or straight from the bowl with a glass of rosé. If you want to see how it sits against Spain’s tiny table classic, our note on the Coquillo olive is a useful companion read — another small olive where patience at the curing stage does the heavy lifting.

A word on colour and ripeness, since it causes confusion at the deli counter. The same Cailletier tree gives green olives if picked early and brown-to-black ones if left to ripen; the dark, wrinkled “Niçoise” you know best is simply the fully ripe fruit, cured. There is no separate black variety — just a later harvest and time in brine. If you would like the wider family tree, our olive varieties encyclopedia sets the Cailletier alongside its Mediterranean cousins.
One honest caveat: because the flesh is thin, the Cailletier bruises and marks easily, and a good cure takes patience. That is part of why authentic Nice-cured olives cost more than a bulk supermarket black olive — you are paying for small fruit, careful handling and time, not a bargain.
Cailletier olives — common questions
Is Cailletier the same as the Niçoise olive?
Effectively yes. “Niçoise” refers to Cailletier olives grown and cured in the Nice area. The variety is Cailletier; “Niçoise” describes where it is from and how it is prepared.
Is Cailletier the same as Taggiasca?
They are generally considered the same cultivar, or extremely close relatives. “Cailletier” is the French name used around Nice; “Taggiasca” is the Italian name used in Liguria. Same small fruit, same mild oil.
Is Cailletier used for oil or for eating?
Both. It is a classic dual-purpose olive — pressed for a soft, sweet oil (roughly 20–25% yield) and cured whole as a small, prized table olive.
Why are real Niçoise olives so small and pricey?
The Cailletier fruit is naturally small with a fairly large stone, the thin flesh bruises easily, and a proper cure takes time. You are paying for careful handling and flavour rather than sheer size.
