Single Source & Traceability — One Grove, One Harvest, One Ledger

Lot-tagged harvest crates of just-picked olives in a terraced Calabrian grove at first light

Ask most olive oil brands where their oil comes from and you will get a country, sometimes a region, often a shrug dressed up as a story. Ask us and we will name the grove, the parcel, the week, and the pressing — and then show you the page it is written on. Single source and traceability are not claims we decorate the bottle with. They are the architecture of the oil itself: one place, one harvest, one unbroken chain of custody from branch to bottle, recorded as it happens rather than reconstructed afterwards.

One named grove, known tree by tree

Our oil comes from a single family estate in San Procopio, Calabria — terraced hillsides at the toe of Italy where the Tyrrhenian wind comes up the slope every afternoon and the same family has worked the same trees for six generations. The groves are not an abstraction here. The family knows which parcels break ripeness first because they face southeast and catch the early sun. They know which ancient trees, the gnarled ones with hollow trunks, carry the most bitter and phenol-dense fruit. They know which terrace stays dry in a wet October because the sea breeze keeps the canopy moving.

That knowledge is not sentiment — it is production control. Because every olive comes from one place rather than a dozen anonymous lots pooled in a broker’s tank, the oil carries a consistent fingerprint season after season: the same soil chemistry, the same cultivars, the same microclimate, the same hands deciding the exact green moment to pick. Terroir is not a wine word borrowed for marketing; it is the measurable reason two oils made the same way in two valleys taste nothing alike. A blend, by definition, averages all of it away. We wrote a full guide to what single origin really means, and it is the foundation of everything we call real quality.

The chain of custody, hour by hour

Traceability is won or lost in the hours immediately after picking. Ours runs like this:

  • Picked by parcel. Each block of trees is harvested separately, and the fruit goes into shallow ventilated crates — never sacks or deep bins, where the weight of the load bruises and warms the olives underneath.
  • Tagged at the tree. Every crate leaves the grove with its parcel and date on it. The record starts in the field, not at the mill door.
  • Milled within hours. The mill sits beside the grove, so the fruit is crushed the same day it is picked — usually within a few hours. Every hour between picking and pressing costs freshness and raises free acidity, which is why distance is the enemy of quality. The full sequence is laid out in from grove to bottle.
  • Pressed cold, kept separate. Malaxation stays below 27°C, and each day’s run is stored in its own stainless tank under inert gas rather than being poured into a communal vessel. Keeping lots separate is more work and less efficient. It is also the only way the ledger stays true.
  • Analysed and logged. Each lot is tested for free acidity and peroxides before it is bottled, and the results go into the same record as the parcel and the date — see the chemistry of quality.

The source stamp: four facts we are willing to print

Every batch we produce carries a source stamp — four verifiable facts, printed because we can prove each one:

  • Origin. The named grove and region the olives were grown in — not packed in. The difference is larger than most shoppers realise; we take it apart in what “imported from Italy” really means.
  • Harvest. The year and window the fruit was picked, deliberately early while the olives are still green and the polyphenols are at their peak. Why this is the most honest date on any label: the harvest date guide.
  • Acidity. The free-acidity figure from laboratory analysis — the clearest chemical record of how gently and how quickly the fruit was handled. What the number actually measures: acidity, explained.
  • Lot. The specific production run, so the bottle in your hand traces back to real entries in a real harvest ledger: which parcels, which days, which pressing.

None of this is difficult for us, because the mill sits beside the grove and the chain never leaves the family’s hands. It is difficult — usually impossible — for anyone selling blended oil. That asymmetry is the entire point, and it is why we tell you to read the back of the label on every bottle you buy, including ours.

Why blenders cannot follow us here

Most olive oil on a supermarket shelf is a blend: oils from several countries, bought on price through brokers, combined in industrial facilities to hit a flavour target and a margin. It is a commodity trade wearing a farmhouse costume. When origin is a moving average, there is no grove to name, no single harvest to date, no meaningful acidity for the batch as a whole, and no ledger anyone could audit — because the thing being sold was assembled from parts that were never tracked individually in the first place.

This is why the industry changes the subject to imagery. The cypress trees on the label, the script font, the invented family name — they are doing the work the supply chain cannot. Investigations have repeatedly found oils sold as extra virgin that failed sensory panel testing; researchers at the UC Davis Olive Center, for instance, found that a majority of imported samples they tested failed to meet extra virgin standards. We lay out the whole trade in why not supermarket olive oil.

Traceability you can actually act on

Traceability is not paperwork for its own sake. It is your protection and our accountability, and it only means something if there is a person at the end of the trail. It means the oil is genuinely extra virgin, genuinely from where we say, genuinely fresh — and that if you ever want to check, you get an answer from the ledger rather than a customer-service script.

We hold the same standard whether you buy a single bottle or supply a restaurant group through our wholesale programme. If you have a question about the grove, a harvest, or the lot number on the bottle in your kitchen, ask us. Naming our source has never been a risk to us. It is the proof. See the oils.
