How Corks Help Our Sustainability Initiative


Did you know cork oak forests make a significant contribution to helping our planet? A cork oak tree lives for up to 200 years and within its lifetime, it becomes a massive storehouse of CO2, which helps reduce greenhouse gas emissions.

Our cork supplier recently honored us with a certificate highlighting our contribution to sequestering 24.6 tonnes of CO2 from the atmosphere - equivalent to what 1,025 trees would capture in a year! The findings are the only ones to date that underwent a multi-closure comparative peer review.

At Andis, we make it a priority to be as sustainable as possible in all that we do, even with our corks. It’s not just because of how it protects the quality of our wines - and, as you now know, our planet - it is also one of nature’s most amazing raw materials that is naturally renewable.


Cork is an all natural raw material that comes from the bark of a Cork Oak tree. It is light, impermeable to liquids and gases, elastic, compressible, provides thermal and acoustic insulation, it is also a fire retardant and highly abrasion-resistant. Not to mention, it is completely biodegradable, renewable and recyclable. 

So yes, we’re big believers in cork.


Every year cork oak forests absorb up to 14 million tonnes of CO2. This ability to retain carbon dioxide is passed on to manufactured cork products, including cork stoppers. What's even better, during the natural regeneration process that follows harvesting, the tree's ability to absorb CO2 increases up to five times. 

In other words, the more it is harvested, the more it protects the environment.
