02 — Food safety

Quality, in practice

Strict control intervenes at every stage of conservation and packaging — every batch can be qualified by geographic origin, variety, soil and operations.
Olive-oil extraction is entirely mechanical, without solvents, at temperatures that do not degrade the oil.
Extra-virgin oil rests in stainless-steel tanks terroir by terroir; owning our groves enables full traceability “from the young plant”.
