Cork Production by Country: Portugal’s 50% and Why Origin Matters

Portugal supplies about half of the world’s cork, with Spain a clear second producer, and nearly all of it comes from the western Mediterranean basin where Quercus suber) forests grow. Morocco, Algeria, Tunisia, Italy and France each add smaller shares. Outside this belt, commercial cork harvesting is negligible.

TL;DR:

  • Harvesters strip cork by hand about every nine years without felling trees, but stopper grade usually arrives at the third harvest, when trees reach 43.
  • Ask sellers to identify the cork’s country of origin, then check for FSC or PEFC certification; commercial harvesting outside the Mediterranean belt remains negligible.
  • Production estimates differ because reports count either stripped bark or processed goods, and forest inventories may lag changes from fire or land use.

Global cork production: the headline figures

Industry estimates for annual global cork output vary, depending on whether a source is counting raw bark stripped from trees or processed cork ready for manufacturing. That gap matters because raw cork loses weight and volume once it is boiled, graded and cut into stoppers or sheet material, so a tonnage quoted at the forest gate will never match a tonnage quoted at the factory door.

The land base behind this output is substantial. Cork oak forests cover roughly 2.2 million hectares worldwide, and almost 1.5 million hectares of that sit in Europe, concentrated on the Iberian Peninsula’s Atlantic coast. The remainder is spread across North Africa.

A few reasons explain why published figures on cork rarely agree exactly:

  • Some reports measure raw stripped bark, others measure finished products such as stoppers or granulate.
  • Forest inventories are not updated every year, so hectare figures can lag real-world planting or clearance.
  • National statistics agencies and trade bodies sometimes use different reporting years or currencies.

Top cork-producing countries: a country-by-country breakdown

Portugal dominates global output, accounting for approximately 50% of global cork production. It holds the largest area of cork oak forest of any country and manufactures the bulk of the world’s cork stoppers, granulate and composite cork products, exporting most of what it produces. Our guide to where cork comes from looks at how that dominance developed and what it means for provenance claims on cork goods.

Spain follows as the second-largest producer, supplying roughly 30.5% of global output. Much of Spain’s cork comes from dehesa, an open woodland and grazing system similar to Portugal’s montado, where cork oaks share the land with livestock and seasonal crops.

Morocco is the leading North African producer, contributing about 5.8% of world supply, with Algeria and Tunisia each adding smaller shares:

  • Morocco: roughly 5.8% of global production, concentrated in the Maamora forest and the Rif region.
  • Algeria: about 4.9%, drawn from forests in the country’s north.
  • Tunisia: around 3.5%, mainly in the Kroumirie mountains.

Italy and France round out the recognised producer group, each contributing modest but specialised volumes. Italy supplies about 3.1% of global cork, largely from Sardinia, while France contributes roughly 2.6%, concentrated in Corsica and parts of the southwest. Both countries maintain smaller, more artisanal cork industries compared with the scale of operations in Iberia.

Cork oaks have also been planted outside this traditional belt, including trial plantations in California, Chile and parts of Australia. None of these produce cork at commercial volumes, and research reviews confirm that Europe produces more than 80% of the world’s cork, with output concentrated in a small number of Mediterranean countries. For buyers, this means a product genuinely made from cork almost always traces back to one of the seven countries above, not to a novelty plantation elsewhere.

Where cork oak forests grow and why

Quercus suber thrives in a specific ecological niche: it needs the warm, dry summers and mild, wetter winters typical of the Mediterranean climate, along with well-drained, often sandy or granitic soils. This narrow tolerance is why commercial cork forestry stays confined to one region of the globe rather than spreading freely.

The montado in Portugal and the dehesa in Spain are the agroforestry systems that make large-scale cork harvesting possible. These are not dense plantations but open, savanna-like landscapes where cork oaks are spaced widely enough to let livestock graze and cereal crops grow beneath them. Commonly cited figures put Portugal’s cork oak area at around 736,775 hectares and Spain’s at around 574,248 hectares, though older inventories can understate recent losses from fire or land-use change. Morocco and Algeria account for most of the remaining area, concentrated in North Africa’s cooler upland forests. Our piece on how cork production supports forests goes further into why this land management matters for biodiversity.

How cork is harvested and why it doesn’t harm the trees

Cork bark is stripped by hand on a rotation of roughly nine years per tree, and the process is non-destructive: skilled harvesters cut and lever away the outer bark without damaging the living layer beneath, so the tree regenerates a new cork layer for the next cycle. A tree’s first two harvests typically produce lower-grade cork, unsuitable for wine stoppers, and it usually takes until the third stripping, when the tree is 43 years old, before the bark reaches stopper quality.

Cork oaks can live for decades, with some reaching roughly 300 years old, which means a single tree can be harvested repeatedly over its lifetime. That longevity, combined with the fact that harvesting never fells the tree, makes cork forestry one of the more unusual extractive industries: the forest stays standing, continues sequestering carbon, and keeps functioning as habitat for species such as the Iberian lynx and Bonelli’s eagle. Our explainer on sustainable cork harvesting walks through the stripping process in more detail.

Cork exports: who ships stoppers and raw material

Trade data for 2024 confirms Portugal’s lead in finished cork products: it exported corks and stoppers worth US$400,676.16 thousand, totalling 7,630,920 kilograms, far ahead of other exporters that year. Spain also features prominently, exporting US$44,702.23 thousand worth, or 7,763,590 kilograms, of corks and stoppers, with France and Italy also appearing among leading exporters.

Portugal and Spain cork stopper export comparison

Trade statistics separate finished stoppers (recorded under codes such as HS 450310 and 450410) from raw, unprocessed cork (HS 450110). On the raw material side, Spain exported 37,639,000 kilograms of raw or simply prepared natural cork in 2024, a volume that reflects its role supplying bark for processing elsewhere, with Portugal and Italy also among the top exporters by weight. Major destination markets for both categories include leading EU wine-producing countries, the United States, China and Japan, tracking closely with global wine consumption patterns. Our post on how wine corks are made covers what happens to raw bark once it reaches a manufacturer.

Industry pressures: substitutes, wine demand and traceability

Synthetic and screwcap closures have displaced a meaningful share of cork’s traditional wine stopper market over recent decades, creating ongoing economic pressure on producers even though the physical supply of cork oak forest remains stable. APCOR notes that Portugal exports over 90% of its manufactured cork output, and that demand ties closely to the premium wine sector, which consumes the majority of the highest-grade natural stoppers. When premium wine sales soften, producer revenue feels it quickly.

In response, the industry has leaned into traceability schemes and environmental marketing, pointing to cork’s renewability and carbon storage as a market-promotion strategy against cheaper substitutes, an approach FAO reporting has also recommended to help sustain rural livelihoods tied to cork forestry.

Why production origin matters when you’re buying cork

Knowing that Portugal and Spain supply the overwhelming majority of the world’s cork gives you a useful filter when checking provenance claims on any cork product. If a seller cannot say which country their cork comes from, that is worth noticing, since legitimate cork almost always traces to one of a handful of named countries rather than an unspecified origin.

Certifications such as FSC or PEFC add another layer of verification worth checking before you buy.

FAQ

What country produces the most corks?

Portugal produces the most cork stoppers in the world and leads global exports of corks and stoppers, shipping US$400,676.16 thousand worth in 2024. No other country comes close to matching its manufacturing scale.

Who is the biggest cork producer in the world?

Portugal is the biggest cork producer overall, supplying around 50% of global cork production. Spain is the second-largest producer, supplying roughly 30.5% of world output.

Is there a shortage of cork in the world?

There is no physical shortage of cork trees or forest area. The main pressure on the industry comes from economic displacement by cheaper artificial stopper substitutes rather than a decline in the cork oak forests themselves.

Why does Portugal produce so much cork?

Portugal has the largest area of cork oak forest of any country, managed through the montado agroforestry system that has supported cork harvesting for generations. That combination of forest area, climate and established harvesting infrastructure keeps Portugal’s output and exports well ahead of every other producer.
