How to read your bottle's trace page

Scan the QR seal on any bottle of our oil and you land on a page like this one: the complete, timestamped journey of your exact lot, from the morning it was picked to the vessel it sailed on. This article explains what you are looking at.

The green banner is the heart of the system. Every production event — harvest, milling, laboratory analysis, bottling, shipment — is written into a tamper-evident digital ledger. Each record is cryptographically chained to the one before it: change a single digit of a past record, even a timestamp, and every subsequent link breaks visibly. "Ledger verified" means the entire history recomputes cleanly.

The laboratory block is where quality lives. Acidity (free fatty acids) must stay under 0.8% for extra virgin — our Tesoro lots typically sit around 0.2%. The peroxide value measures early oxidation: lower is fresher. Polyphenols are the antioxidants responsible for bitterness, pepper and shelf life; anything above 250 mg/kg is serious oil, and early-harvest Chetoui can double that.

The shipment block matters if you bought our oil abroad. It names the destination market, the port of loading and the Incoterm of that consignment. If a bottle sold in Tokyo shows a lot that was shipped to Brazil, something is wrong — and we want to hear about it.

Counterfeiting is the olive oil industry's oldest disease, and paper certificates have never cured it. Our answer is radical transparency: the same records our export clients audit are the ones any shopper can open from the shelf. If a bottle claims to be ours and its lot number returns not found, do not buy it — photograph it and write to contact@fas.com.tn.
