Cork best for wines and best for the environment

natural wine cork supplier

Here is a film about why natural cork from Portugal is the best solution for bottling wine both in terms of its quality as a sealant and the environmental benefits. The cork oak forests of Portugal are among the most biologically rich on earth and harvesting the cork only requires the bark being stripped – the trees live on! Plastic … Read More

Aluminium and plastic closures vs cork: the environmental battle

wine cork supplier

A study was carried out a few years ago by PriceWaterhouseCoopers to look at the environmental impact of different wine closures, considering cork, aluminium and plastic options. What they looked at was the lifecycle of each type of closure to work out the cost to the environment of 1,000 closures, in terms of energy, water consumption, air pollution and solid waste. … Read More

Skilled production of natural wine corks disappearing

punching natural cork stoppers

Not so long ago, all corks were what are now termed natural, that is punched out of the cork bark by a skilled worker with a punching machine and a lot of patience (see photo below). Sadly these natural wine corks are gradually being replaced by agglomerated corks, which are far easier to make and do not require anything like … Read More

Storage of cork stoppers

capsulated corks

We receive a lot of questions about how cork stoppers should be stored once they have been received by clients. The most important thing is that once you have received your cork stoppers from your supplier, you should use them to bottle your wine or whatever within around 6 months. After this time the surface treatment (generally silicone or paraffin) … Read More

Sourcing cork from Portugal

There are not many industries that Portugal can claim to be the world leader in, but cork is one of them. In fact around 70% of the world’s cork is exported out of Portugal and for quality natural cork stoppers, the figure is over 95%. So if you are buying cork from within your own country, the chances are that … Read More

Agglomerated or natural corks?

So should you choose agglomerated or natural corks for your stoppers? Assuming that you are not going to use a synthetic option (screw tops or worse still a plastic cork imitation), what are the different characteristics of agglomerated and natural corks? Within the agglomerated cork bracket, you can opt for micro-agglomerated (with 0.5 to 2.0mm granule size) which have the … Read More

Different qualities of natural wine corks

The system of classifying natural wine corks into different quality categories is to say the least a complex one. The key thing to understand is that there is no cross industry standard applied to corks coming out of Portugal (where the vast majority of natural wine corks are produced) and more complicated still, broad quality standards vary considerably from country … Read More

Cork from Portugal – nothing gets thrown away!

Because cork is a natural product that can only be harvested from one kind of oak tree, there is a limited supply. It is also quite expensive to harvest from the trees, as the bark has to be removed by hand. This means that cork is not a cheap raw material! It has unique properties and has a certain beauty … Read More

Natural wine corks classification

Natural wine corks are still used to seal the vast majority of the world’s best wines, because all the other solutions (either synthetic or other cork options, such as micro-agglomerated, normal agglomerated or 1+1 technical corks) do not offer the unique properties that natural cork offers as well as the cosmetic appeal. We are not going to look at which … Read More

Cork as an environmentally friendly choice

It is great to see people from outside the cork industry talk about the benefits to the planet of using cork rather than synthetic alternatives – this is true for cork closures for wine bottles and of course for its other uses such as insulation or flooring.

Screw cap threat drives cork innovation

Five to ten years ago there were various people declaring that the cork industry would be largely consigned to history as screw caps take over from cork stoppers for wine bottles, but in fact over recent years corks have been increasing their share of the market rather than losing it. The truth is that the major players in the cork … Read More

Expanded cork – how it is made

Expanded cork (or black cork) is made from the bark of the cork tree that is of too poor a quality to be used for making natural wine corks. Principally this is from branches that are pruned from cork trees (see photo below), fire damaged cork from forrest fires and ‘virgin’ cork (the cork that come from the first harvest … Read More

In recent years there has been a lot of development in using cork agglomerate in innovative ways, by mixing different kinds of corks granules, adding colours, varying the densities and so on. The main way that this is done is to add cork granules and adhesive into a block mould, then to apply pressure. What emerges is a block typically … Read More

Technical / 1+1 corks supplier

1+1 corks are made from an agglomerated cork body with natural cork discs glued on to each end. So natural cork will be displayed to the consumer when about to open the bottle and will also be in contact with the wine in the bottle. Agglomerated cork is a good deal less costly than natural cork, so by just using … Read More

Expanded cork / black cork supplier

Expanded cork was developed in the mid 1990s to provide a 100% natural insulation material, using parts of the cork bark that were not previously used.

Over 70% of the world’s wine corks are made in Portugal and the percentage is quite a lot higher than this for natural corks and other high end corks.

This allows us to make all sorts of things out of … Read More

Cork is actually just another name for the bark of particular oak tree (Quercus suber, more commonly known as Cork Oak), which is native to southwest Europe and northwest Africa. They can grow as tall as 20m and live for over 150 years and form stunningly beautiful forests, particular in central and southern Portugal where they are very extensive (accounting … Read More

Classification of natural wine corks

Sourcing wine corks can be a complicated business – even if you have decided to use natural corks (rather than colmated, agglomerated, 1+1, or micro-agglomerated), then you have to decide what classification of natural cork you want (extra, super, first, second etc) and then what kind of finish treatment you require for the corks. Here we would like to consider … Read More

Cork stoppers continue to take market share from synthetic alternatives

10 years ago, things didn’t look that great for the cork stoppers industry, with strong growth in sales of plastic and aluminium alternatives as a more reliable and cheaper alternative.
