\"Ancient<\/figure>\n

Walk into our grove above San Procopio in May and the first thing you notice is the sound. Bees working the clover between the rows. Wind in the wild oats. A grove farmed conventionally at the same hour is quiet, because the ground between its trees has been sprayed bare and there is nothing living in it to make a noise. That difference, between a hillside that hums and one that is silent, is what organic means to the Posterino family. The certificate came later. The practice is six generations old.<\/p>\n

What organic actually guarantees in olive oil<\/h2>\n

Our groves are certified organic under the European Union’s organic regulation, which is among the strictest frameworks in the world and is enforced by annual inspection of the land, the records and the oil. In practice it means no synthetic fertilisers, no synthetic pesticides and no herbicides, ever; a documented conversion period before certification is granted; and full traceability from the tree to the lot number on your bottle. It is worth being precise about what it does not guarantee. Organic certification says nothing about whether an oil is fresh, whether it was harvested green, or whether it is any good. Plenty of organic olive oil is late-picked, over-stored and dull. We wrote honestly about that gap in is organic olive oil worth it<\/a>. The certificate is the floor. Everything on this page is what we build above it.<\/p>\n

A grove that defends itself<\/h2>\n

The ground between our trees is never bare. Clover, vetch, wild oats and poppies are allowed to grow knee-high through spring, then cut and left where they fall. None of it is decoration. The living cover feeds pollinators and shelters the lacewings, ladybirds and parasitic wasps that keep the olive fruit fly in check; it holds the thin hillside soil against the violent autumn rains; and as it breaks down it returns organic matter and nitrogen that the trees will spend the summer drawing up. Where conventional groves reach for a broad-spectrum insecticide, we hang pheromone traps, monitor the fly count tree by tree, and pick early enough that the fruit is off the branch before the worst of the pressure arrives. It takes more walking and more attention. It also means that when the fruit reaches the mill it is clean, whole and undamaged, which is where great oil begins. We describe the picking itself on the harvest page<\/a>.<\/p>\n

Long arithmetic, not ideology<\/h3>\n

Synthetic nitrogen can force a bigger crop this year. Herbicide can save a week of labour. A blanket spray can wipe out every insect in the grove, pest and predator alike, in an afternoon. Each of these borrows against the next decade: soil that loses structure and life, a water table that carries what was sprayed, trees that come to depend on inputs they never needed. Some of the trees in our care were planted by ancestors the family knows only from photographs. The intention is that people not yet born will harvest them. You do not mortgage a two-hundred-year asset for one fat season, and that is the whole of our philosophy on chemicals.<\/p>\n

Why it shows in the glass<\/h2>\n

Here is the part that matters at your table. A tree working with a living soil, rather than one force-fed soluble nitrogen, grows fruit with more concentrated character and, in our experience and in the wider literature on olive cultivation, a higher load of the polyphenols<\/a> that give a great oil its bitterness, its pepper and its resistance to going rancid. Clean, undamaged fruit, milled within hours of picking, produces an oil with nothing muddying the signal: no fermented or fusty defect from bruised olives, no residue, no flatness. What you taste is the grove exactly as it stood in October. We think of organic farming as a flavour decision first and an ethical one second, and the two happen to point the same way. The chemistry behind it is on our page on acidity, peroxides and freshness<\/a>.<\/p>\n

Sustainability as stewardship<\/h2>\n

To the family, sustainability is simply keeping faith with the land, and most of it is older than the word. Old groves on deep roots need remarkably little water, and what irrigation the younger plantings receive is dripped, not sprayed. Prunings are chipped and returned to the rows or burned for winter heat. The pomace left after milling goes back onto the land as compost rather than to a solvent plant. The mill runs on the same hillside as the trees, so the fruit travels minutes, not days, and the oil is stored in stainless steel under nitrogen until it is bottled to order. None of this is clever. It is the oldest agricultural logic there is, carried without interruption for six generations and through every step from grove to bottle<\/a>.<\/p>\n

How to check us<\/h2>\n

Every bottle of our organic oil carries the EU organic leaf, the certifying body’s code, the harvest date and the lot number. Ask us for the certificate and the laboratory analysis for any lot and we will send them. We would rather you verify than trust, because that is the standard we would want applied to anyone selling us food. The full story of who we are and how the farm came to be is on Our Story<\/a>.<\/p>\n
