Extra Virgin Olive Oil

  • Olive Oil
    Olive oil has been constantly present as an indispensable element of nutrition and social survival in all Mediterranean cultures for four millennia, and probably longer. The archaeological evidence of prehistoric oil lamps shows that long before proper comestible oil had been perfected by about 2000 Before Our Era, the rude greasy muck extracted by pre-agricultural man served to satisfy his need of making light, of illuminating darkness, of keeping at bay the terrors of the night . . . and in fact, oils not of comestible quality were used for home illumination in many Mediterranean rural areas until well after World War Two. Besides their alimentary uses, good oils have always been vitally important as medicinals and cosmetics and as deeply-rooted symbols in religions and mythologies . . . Noah’s olive branch, sacred ritual anointings, Odysseus’ marriage bed built out of the living trunk of an olive tree, a recently-founded Italian progressive political party, to name a few.

    By the time of Moses, around 1800 Before Our Era, olive cultivation - the Old Testament speaks often of it - had spread to all the then-known arable lands around the Mediterranean, an economy carried farr afield many centuries later by Roman expansion. Many different kinds of trees and fruits came out of this, partly by natural selection in different soils and climates, partly by empirical observation and grafting for desirable traits. In the course of the eighteen centuries between Caesar and Napoleon, nearly all of the then-populated Italian peninsula lying below certain temperature limits broke forth in olive trees that bore fruits of widely different characteristics. Today the oils from the lands around Lake Garda in the north are considered the lightest, those from Liguria the most fruity, the Tuscan ones the most balanced in extremely fine olivy flavour, robust consistency and durability, the Apulian ones the pepperiest, and so on through many zones and regions. The long-proven healthfulness of diets based on ample lashings of extra-virgin olive oil need hardly be reit-erated here . . . by now universally known, it attracts new and contented adherents every day.

    HISTORY
    The oldest traces of plants that may be thought of as the ancestors of olive trees have been found in south-central France and dated to about fifty million years ago. Olive-tree fossils have turned up in the Sahara Desert. Prehistoric man doubtless ate the small, harsh, bitter olives he found on wild trees. After roughly 2000 Before Our Era, olive culture and the complicated science of oil extraction spread outward from the eastern Mediterranean basin into Anatolia, Egypt and Greece. Much later, by the first century Before Our Era, oil production had become so vital to Roman Italy that thousands of Greek slaves, trained and specialised in these arts, worked vast estates for domestic use in the endless empire and for export to the barbarian north. After the fall of Rome in the fifth century of Our Era, Italian production fell on hard times and eventually all but perished, but the Arabs in Spain not only carried on old traditions but developed new and better methods.

    Around the year One Thousand, in the times of the Italy of the City-States (Comuni), new impetus was given to this so very vital economy, at first especially in Tuscany around Florence and Siena but soon, by about 1300, all over the peninsula. Not only did good extra-virgin oil become an indispensable staple of diets but also an index of prosperity, even of wealth. Ever since about 1880, all of southern Italian agriculture has been pivoted on oil production in great quantities, with less attention to quality. For long now the extra-virgin oils of the Centre and North, especially of Liguria, Tuscany and Umbria, have led in quality by unbeatable margins, as is recognised by demanding gourmets the world over.

  • PRODUCTION METHODS
    Unlike wine, olive oil doesn’t improve with age - it deteriorates. Within one year most of the good qualities of a pressing can be lost. For maximum conservation and general quality, only olives picked from the tree must be used, never windfalls or other gleaned from the ground because these have already begun to ferment. All the succeeding phases from storage to washing, crushing and pressing must be undertaken very quickly. Conscientious producers will limit storage of the picked crop to forty-eight hours and perform the separation of leaves from the fruit, the washing and the crushing within two days more. Only cold pressing will do for obtaining really good products - hot pressing yields much greater quantity but severely impairs quality. Oil is extracted from the crushed pulps by centrifuge or vertical presses. An oil qualifies for extra-virgin if the acidity is kept to below one per cent and if no chemical additives of any sort have been used in the production. A good oil must be kept in a dark place at temperatures not above 20°C.

    AREAS OF PRODUCTION
    Italy boasts of between 550 and 715 different types of olive trees, among them, in the North and Centre, the Biancheira of the Friuli; Casaliva, Favarol and Grignan of the Veneto, Lombardy e Trenton; Taggiasca of Liguria; Nostrana di Brisighella of Emilia; and Tuscany’s rich, fruity Frantoio, Moraiolo, Leccino and Pendolino. In the Centre and South, to name a few prominent ones, Rosciola, Sabina, Rotondella, Carpellese, Gentile di Larino, Coratino, Ogliarola, Pizzuta, Carolea, Ottobratica, Biancolilla, Nocellara, Bosana and Tonda of Cagliari. Apulia has the densest concentration of trees and yields forty per cent of Italy’s oil output, or ten per cent of the world’s. Calabria and Sicily, too, are major contributors to this economy.
