The Rising Art of Canned Seafood

In Lisbon, there are shops that sell nothing but tinned fish. They are not convenience stores. They have design-forward interiors, knowledgeable staff, and cans priced at €8–€40 each. The tins are displayed like wine bottles, labeled by producer and year. Some of the sardines have been aging for a decade. The shops are full. The category is the fastest-growing segment of specialty food retail in southern Europe, and it is arriving — with some force — in the United States, the United Kingdom, and beyond.

The serious food world's rediscovery of canned seafood is not a trend. It is a correction. The Iberian Peninsula — Portugal and the Spanish Basque Coast in particular — has maintained a culture of premium tinned fish for a century and a half, producing conservas that were never considered a compromise by the people who made them or ate them. What has changed is that the rest of the world has noticed, aided by a generation of food writers, chefs, and importers who understand that a can of Ortiz white tuna belly in olive oil is not remotely the same object as a supermarket tin of tuna in water.

The Portuguese Conserva

Portugal's canning industry began in the 1880s when French entrepreneurs established factories along the Atlantic coast to process the sardine catches that were overwhelming local markets. By the early 20th century, Portuguese conservas were being exported across Europe and South America, and the distinctive decorated tins — each cannery developing its own graphic identity — had become as recognizable as the fish inside. The industry declined through the mid-20th century as frozen and fresh fish became more accessible, but a core of quality producers maintained the traditional methods: hand-selected fish, cleaned by hand, packed in high-quality olive oil or sauces, sealed, and sterilized.

The revival began in earnest in the 2000s, led by producers who understood that what they were making was not shelf-stable convenience food — it was a product that improved with age, demanded quality raw materials, and deserved the same consideration as any other artisanal food. José Gourmet, founded in 2009, is the producer most associated with bringing Portuguese conservas to an international fine food audience: their tins feature illustrated labels by Portuguese artists, their fish is sourced from sustainable Portuguese fisheries, and their spiced octopus in olive oil has won awards at food competitions that do not usually consider tinned food a category.

The Comur brand operates seven conserva shops in Lisbon under the name "The Fantastic World of Portuguese Sardines" and sells vintage sardines by year — the understanding being that older sardines, like wine, develop complexity with age. A 2010 sardine from a good year is softer, richer, and more complex than a 2023 sardine from the same producer. The shops sell tasting kits. They have waitlists for certain vintages. This is not ironic. It is entirely serious.

The Spanish Benchmark: Cantabrian Anchovies

The finest anchovies in the world come from the Cantabrian Sea on Spain's northern coast, caught between April and June when the fish are fattest, salt-cured for six to twelve months in wooden barrels, then cleaned by hand, filleted by hand, and packed in sunflower or olive oil. The production is labor-intensive in a way that explains the price — a single 50-gram tin of Cantabrian anchovies from Ortiz, the benchmark producer, costs €8–€12 — and the flavor is unlike anything labeled "anchovy" that most consumers have encountered.

Where a supermarket anchovy is aggressively salty and fishy to the point of being used as a background flavor, a Cantabrian anchovy is a complete, nuanced thing: umami-rich, deeply savory, with a clean finish and a texture that holds its shape rather than dissolving. Eaten on good bread with unsalted butter — the Basque preparation — it needs nothing else. La Brújula, Don Bocarte, and Nardin are the other producers worth knowing, each with slightly different flavor profiles based on their curing time and oil choice.

The ventresca — the belly of the bonito del Norte, the white tuna of the Cantabrian Sea — is the other Basque conserva essential. The belly is the fattiest, most tender cut of the fish, packed in olive oil within hours of landing. Ortiz Bonito del Norte Ventresca is the product most cited by chefs when discussing canned seafood: the flesh is white, in large pieces, genuinely buttery in texture, and entirely unlike canned tuna as most of the world understands it. It costs €14–€18 for a small tin. It is worth every euro.

Why the Can Works

The science of why good conservas are good is straightforward: the canning process, when applied to high-quality raw materials in good oil, seals in the flavor of the fish at its peak and allows the oil, the fish proteins, and the salt to interact slowly over months and years. The result is not preserved fish — it is transformed fish, in the same way that dry-aged beef is transformed beef, or aged cheese is transformed milk. The starting quality determines the ceiling. With inferior fish, inferior oil, and industrial processing, the ceiling is low. With exceptional raw materials and traditional methods, the result is genuinely extraordinary.

The rise of the conserva in serious food culture is partly a reaction to the excesses of fine dining's molecular era — a turn toward simplicity, craft, and the recognition that the best ingredients, treated with respect, need very little done to them. A tin of Ramón Peña clams in brine, opened at the table and eaten with lemon juice and cold white wine, is a complete dining experience. The tin is not the compromise version. The tin is the point.

The Producers Worth Knowing

Ortiz is the entry point and remains the benchmark for Cantabrian anchovies and white tuna. Their glass jars of anchovies in olive oil are the version most commonly available outside Spain and are the correct introduction to the category. La Brújula produces anchovies with a slightly longer cure and a more complex, less salty profile — the choice for those who want to explore beyond Ortiz. Don Bocarte is the premium tier: family-operated, small production, the anchovies packed individually in a single layer and priced accordingly.

In Portugal, José Gourmet and Conservas Portugal Norte represent the contemporary fine food approach: sustainable sourcing, artist-designed labels, and a range that extends beyond sardines to include mackerel, squid, and various preparations with pimentón, lemon, and spiced olive oils. The Lisbon brand Comur is the most design-forward of the Portuguese producers and the most accessible to international buyers through their online shop.

In the United States, the importer Donostia Foods has been the primary advocate for Basque conservas since 2012, curating a selection of Spanish producers and making them available through specialty retailers and their own online store. Despaña Brand Foods in New York carries the most comprehensive selection of Iberian tinned fish available in America. For Portuguese conservas, the importer Luso Foods has done the equivalent work, and Zingerman's Mail Order in Ann Arbor carries an excellent curated selection of both Spanish and Portuguese producers.
