Five years unopened, and it improves for three of them. Store dark and level.
On the palate
Buttery, faintly sweet, clean iodine finish. The oil is as good as the fish.
Where this dish comes from
Packing fish in oil is Mediterranean and very old: Roman garum workshops in Baetica and Lusitania were salting and jarring small fish on an industrial scale by the first century, and amphorae stamped with their makers' names have been dredged from wrecks all along the trade routes.
The modern tin arrives with Nicolas Appert's 1795 preserving experiments and Peter Durand's tin canister patent in 1810. Brittany and later Galicia and Cantabria turned that invention into an art: the conserva, a tinned fish deliberately aged so the oil and the flesh exchange character. In Spain and Portugal a great tin is vintage-dated and cellared like wine.
Houses such as Conservas Ortiz (founded 1891) and La Brújula built the reputation of Cantabrian conservas, and the Portuguese tinned-fish revival of the 2010s put them on tasting menus from Lisbon's Belcanto to New York's Cervo's. Ferran Adrià famously served a plain, perfect tin at elBulli staff meals as a lesson in restraint.
How we make it
Sardines must be brined within hours of landing or their oils go metallic. Ours are brined on the quay, grilled just enough to firm the flesh, and filleted warm — the only moment the bones come away cleanly without tearing.
Then the slow part. Packed head-to-tail so each fillet touches oil on every face, they sit six months in a cool room and are physically turned four times. The flesh softens, the arbequina takes on a faint marine sweetness, and what was a fish becomes a conserva.
Brine, grill, then oil-mature
6 months maturation
01Caught at dawn and brined within four hours of landing.
02Grilled briefly over charcoal to set the flesh, then filleted by hand.
03Packed head-to-tail in single-estate arbequina with a single bay leaf.
04Turned every quarter for six months until the flesh takes on the oil.
Straight from the tin with bread, or warmed thirty seconds and pressed onto toast.
