Where Does Cork Come From What Is A Cork Oak Tree

Cork is a natural impermeable buoyant material used in a variety of products for over 5000 years.The cork is mainly composed of a substance that repels water called suberin. This substance enables cork to have unique properties such as being lightweight, soft, buoyant, fire retardant, impermeable to gas and liquid, termite resistant, rot-resistant, and elasticity.Cork has many known applications for thousands of years. The most common one is as a bottle stopper, mainly for wine glass bottles. Over 60% of all cork-based production represents cork stoppers. It also offers many other uses such as badminton shuttlecocks, bulletin boards, corkboard for insulation of electronic devices, biodegradable cell phone cases, the core of cricket balls and baseballs, temporary skin covering for burn victims, carburetor float bowl gaskets, wallets, sunglasses cases, purses, thermal insulation for floors, house walls, ceilings, and facades.In ancient Greece, cork was used in footwear as a sole. In about 3000 BCE, cork was used for fishing equipment, domestic applications, and sealing containers in Egypt, China, and Persia. Due to the development of several cork-based agglomerates, a massive expansion in the cork industry showed up during the early 20th century.The modern-day marvel is the cork fabric made from the cork bark of a cork oak tree. This fabric is environmentally friendly and an amazing alternative to vinyl or leather. It has many magical properties like it is washable, stain-resistant, durable, hypoallergenic, and antimicrobial. Cork fabric looks unique with a soft and smooth touch like quality leather.If you like to explore more such articles, then take a look at where does cotton come from?

It is native to southwest Europe and northwest Africa, including countries like Portugal, Morocco, Italy, Algeria, Spain, Tunisia, and France. Of these countries, Portugal is the largest cork producer, with over 49.6% of the world’s cork production.The cork oaks are medium-sized, unique, and valuable tree species that grow to a height of 65 ft (20 m). They are evergreen than other oak trees as they do not drop their leaves and have the unique ability to revive their outer bark when stripped off. This is instead a sustainable product that preserves the ecosystem and environment. Cork does not come from the ocean but from the cork oak trees (Quercus suber) that predominantly grow along the Mediterranean sea coast with the perfect conditions of high humidity, plenty of sunshine, and low rainfall. Of about 2,200,000 hectares of the world’s cork forest, Portugal holds 34%, and Spain is 27% of the cork trees.Cork forests are vibrant with biodiversity. Many endangered species and rare species of plants, birds, fungi, and animals live here. They also experience frequent droughts, wildfires, and temperature fluctuations. Since cork is an excellent insulating material, it acts as a protective force from the harsh conditions of the forest that would occasionally happen in the hot Mediterranean summers.In general, cork comprises about 40% of suberin and 22% of lignin. This composition varies depending on growth conditions like geographic origin, soil, genetic origin, climate, tree dimensions, and age. Where does cork for wine bottles come from?Cork has been known as a bottle stopper for more than 400 years. Its unique properties, such as being impermeable to liquids and gas, make it the best-suited material to use as a stopper for wine bottles because it prevents the cork from rotting.Cork oak is the leading source for most cork products in the world, including wine bottle stoppers. Portugal produces a majority of the natural cork, particularly utilized in the wine industry. At the beginning of the seventeenth century, cork stoppers were introduced by Dom Perignon, a Benedictine monk, who used them to seal the bottles of his famous champagne.The majority of people know corks as stoppers in wine bottles. Every year about 13 billion wine corks are produced. Each cork oak tree can produce cork that is enough to process about 4,000 wine corks. After the second harvest, the tree needs to grow for another nine years to get the bark used to produce wine corks because the first virgin harvest does not have a suitable structure required for wine stoppers. Usually, this first harvest is ground up, molded into large blocks for use as other cork products.Producing a wine cork is a lengthy process. The cork is stripped off during the months of June, July, and August using a long-handled hatchet by workers to cut sections out of the bark without damaging the inner layer of the bark; otherwise, it won’t grow back. Good cork companies store these sections carefully on concrete rather than bare earth to lower the risk of contamination. The cork slabs are then boiled to soften them, and the rough outer layer of the bark is stripped away. Later, holes are punched on the boiled cork planks to make out bottle stoppers and shipped to various destinations. These holed planks are ground up and molded to make other cork products, such as cork tile flooring, etc.Where does cork bark come from?Cork bark is a thick dark grey outer layer that covers the portion of the cork oak tree. Cork oaks live up to 300 years old and yield 13 to 18 harvests in their life. During the harvest, the tree bark can be peeled without killing or cutting down the tree.Cork plant tissue is made up of a network of cells filled with 90% air. These cells provide resiliency and sound insulating properties that can protect cork oak against fire. Therefore, cork can be compressed up to 40% and quickly retain its original shape.Cork comes from the bark of the living cork oak tree, a conglomeration of millions of dead cells composed of a waxy substance called suberin and are impervious to water.Where does cork come from, and how is it harvested?Cork oaks grow very slowly, and even the bark grows equally slowly. The trees must grow for over 25 years to produce the first harvest, which is usually known as virgin cork. After reaching maturity, its bark can be stripped once every nine years as long as the tree lives. The harvest year is marked on the tree trunk so as not to be harvested at the wrong time.Cork production does not harm the trees in order to harvest the bark and is thus regarded as the most sustainable process globally by the Forest Stewardship Council.After the tree bark is removed, it quickly forms new protective layers, and stripping the cork bark is also beneficial to the tree’s health and the environment. Cork oak has unique inherent powers that absorb higher carbon dioxide levels even after harvested plant bark.Cork is one of the biggest export of Portugal. The cork trees are grown in about 2.15 million hectares of the Montado landscape of Portugal, which provide the highest yield of cork annually, accounting for 50% of the total cork production.Cork is popular in Portugal as it is economically viable to the local farmers. They store water and nutrients in their roots which preserve the Mediterranean environment. Therefore, Portugal has taken drastic action to protect cork oak trees, and it is considered a severe offense to cut down a cork forest.Here at Kidadl, we have carefully created lots of interesting family-friendly facts for everyone to enjoy!
