How Much Cork Does Portugal Produce? (2026 Data)

How much cork does Portugal produce? Almost exactly half the world's: 49.6% of global cork output, about 99,000 tonnes a year, harvested from 736,000 hectares of cork oak - a third of all the cork forest on Earth¹. The bark made Portugal's modern export economy, and the page's two other resources bracket it in time: gold, which came the other way across the Atlantic - officially 800 tonnes of it from colonial Brazil in the 18th century, more than twice the 382.66 tonnes the Banco de Portugal still holds today²³- and crude oil, 15,267 thousand tonnes of which arrived in 2024, led by Brazil at 30.5%⁴⁵. Three resources, three data cultures: cork is measured by an industry yearbook corroborated by peer-reviewed economics; the colonial gold is history, where the official figure is a floor (the crown's 20% quinto tax bred smuggling); oil is hard Eurostat trade data, partner by partner. The page keeps the three apart, labels each, and answers the searches in order - cork first, gold second, oil last. A word on why these three resources share a page: the search box treats "cork, gold, exports" as one Portuguese identity, and the pairing is older than SEO. Cork is the pre-industrial resource the country still owns outright; gold is the colonial windfall the country received and spent; oil is the modern dependency the country manages. Read together they measure three different economic relationships with the world - monopoly, extraction and dependence - and each number on this page is a snapshot of one of them. The 2026 snapshot says the monopoly endures, the stock is preserved, and the dependency has diversified its suppliers but not its nature.

The cork empire, measured

Portugal share of global cork production stands at 49.6% - and the share grows as the bark moves up the value chain: 34% of the world's cork oak forest, 49.6% of raw production, 62.1% of end-user products, worth EUR 1,016.1 million a year¹⁶. How much cork comes from Portugal, in tonnes: about 99,000 of the world's roughly 200,000-tonne annual harvest, stripped on a nine-year cycle from trees that work for two centuries and give stopper-grade cork only from their third stripping, at about age 25⁵¹.

How much of the world's cork comes from Portugal is therefore a question with one answer in three densities: half the raw material, two-thirds of the products, a third of the forest - the conversion ratio that makes cork Portugal's quietest industrial monopoly⁶¹.

The biology explains the industry's shape. A cork oak cannot be stripped until its bark is thick enough, and the first two strips - virgem and secundaria - are too irregular for stoppers; only from the third harvest, when the tree is about 25 years old, does amadia-grade cork reach the punch line of a wine bottle. Each tree then yields nine or ten strips on a nine-year rhythm for two centuries, which makes cork forestry less like agriculture and more like a slow annuity planted by great-grandparents¹it⁶(official)⁴²³. The gold-era chart puts the two numbers side by side: the colony's century versus the republic's vault.

Where did the colonial gold go, if not into the vault? The historical ledger reads like a drain: the British trade treaty of 1703 (the Methuen Treaty) swapped Portuguese wine for English cloth and, indirectly, recycled Brazilian gold into English industrial capital; the royal treasuries financed the rebuilt Lisbon of Pombal after 1755; Napoleon's invasions carried off what remained of the court's liquidity; and the 1891 sterling collapse gutted the paper gold standard. The 382.66 tonnes that remain are the fortuitous residue of accumulation in the twentieth century's calm decades - bought and stored, not inherited²(official)⁴relay)³. The colonial echo in the trade table is real but modernised - Angola, the colonial-era supplier, has slid down the list as Brazil and the Atlantic basin took over⁴intake[[435|eu]]⁵relay)²³relays)¹edge⁸⁶.

The two commodities tell opposite stories about the same economy. Cork is a renewable, sustainable industry with a secure future: the montado oak forests are managed on 25-year harvest cycles, the material faces no serious synthetic substitute in wine stoppers, and demand for insulation and design applications keeps growing. Gold is the exact reverse: the deposits are exhausted, the mines are closed, and the 800 tonnes that left the country in the colonial era live on only in museum collections, church altars and the national imagination.
