How They Make Provence Olive Oil
In Provence, the olive harvest usually begins in November and lasts until the end of January. The olives selected to make the oil are washed in cold water and then crushed by a millstone and worked into a paste. The paste is then pressed between large discs (known as scourtins) traditionally made of hemp, though today nylon is frequently used. Eleven or 13 pounds of paste are spread on each disc, and the discs are then stacked together (25 to 50 at a time) on the hydraulic presses. As the discs are pressed together, the liquid parties—oil and water—drain into the centre of the press and are then separated.
Olive oil produced by this method is known as first cold pressed olive oil, and is a pure product. In Provence, it takes five kilograms (10 pounds) of olives to produce one litre (34 ounces) of oil.
“The olive trees are silver, with sometimes a hint of blue or greenish bronze whitening against earth that is yellow, violet, orange or a dull red. But always so hard, hard, hard … it suits me well to work with gold and silver.”
– Vincent Van Gogh
Types and Tastes
Olives can be picked at any time, and their degree of ripeness determines their taste. Green olives have very little oil, their flesh is firm and unripe, and they have a sharp tang. Black olives are full of oil, the flesh is soft and ripe, and they have a mellower flavour.
Green olives are inedible unless treated to remove their bitter glucosides, which can be done simply by washing them for about 10 days in fresh water. They are then immersed in brine, which often contains herbs or lemon. Black olives, being fully ripe, only need washing and preserving in brine or salt.
Picholine: The main variety of green olive found in France, the fruit is small and long.
Lucques: A superb table olive, the fruit is long and curved and the flesh is green and fruity.
Tanche: This is the olive of Nyons, a large, delicious olive picked for the table and pressing into olive oil.
Cailletier: Also known as the Niçois, a tiny, smooth black olive with a wonderful aroma.
Aglandau: Famous for its finely flavoured oil, often found in the Alpilles.
