António Almeida – Cortiças


Cork is an invaluable richness of Nature. The regular stripping of cork from the cork oak is a fundamental contribution to the ecological, economic and social sustainability of vast areas of rural land from the Mediterranean Region, where cork oak forests occur and are exploited. António Almeida Cortiças has the privilege of benefiting from this gift.

We believe that the Cork Stopper is the ideal solution for sealing all kinds of wines. Despite the technological advances made in the search for new sealing solutions, in particular in the search for synthetic materials, the molecular characteristics of cork confer unique sealing properties to cork stoppers, adaptable to the different kinds of bottles, thus enabling the balanced wine ageing.

Cork stoppers are a particularity of the wine sector and their use has a major impact on the sustainable conservation of the forest. As a result of this important role, the counteraction of cork stoppers against carbon emissions should be taken into account. Scientific studies on the extraordinary properties of natural cork and several decades of use of cork stoppers to preserve great wines are indisputable evidence that allow us, strictly speaking, to consider it the closure par excellence for all kinds of wines.

Over the years, certain of the excellence of natural cork, António Almeida Cortiças has been steering all human and technical resources to the product manufacture and control, thus contributing to the preservation of great wines and to perpetuating the rituals of elegance and tradition.


Sustainability and environmental impact reduction are the order of the day. So, we cannot minimise the importance of such recognition by a world organisation governing the wine trade. The cork stopper is the only closure option for wine producers, distributors and retailers seeking to minimise their carbon footprint and adopt best practices in terms of environmental performance..

Mindful of the current economic situation and the growing awareness of social sustainability, the company António Almeida Cortiças, supported by a model of social and environmentally responsible management, has engaged in a deep restructuring of industrial infrastructures, in order to reduce industrial waste, rationalise the consumption of water and electrical and fossil energies, favouring the use of alternative energy sources with the aim of reducing CO2 emissions.

The production of a natural cork stopper is capable of absorbing about 7.9 g of CO2, when the entire cork sector, from the forest to the final stopper, is taken into account. Extrapolating the ecological footprint, we can conclude that the production of 500 million corks/year allows the retention of 4,000 tonnes of CO2/year. Forest sustainability assumes a prominent role in the environmental policy of António Almeida Cortiças. The company’s shareholders own several cork oak forests, totalling 1,180 ha, and manage the land on the basis of biological agricultural practices, forest regeneration and revitalisation, as well as planting young cork oak trees in new areas.

With a global view of the product and process, António Almeida Cortiças creates added value, admittedly important for a World that is more aware and sensitive to major environmental issues.


António Almeida Cortiças, follows a policy of continuous improvement, fully guaranteeing the high standards of quality of its products. We believe that Quality starts in the forest, in the permanent monitoring of the development of cork oak forests. António Almeida Cortiças has a team that specialises in ensuring raw material of high quality for the manufacture and supply of high performance corks.

The Quality Policy of António Almeida Cortiças has been implemented for many years and covers the whole production area. The company has an internal laboratory fully equipped with the latest analysis and control technology and managed by highly qualified technical staff. Sampling methodologies and demanding testing protocols are continually put into practice, in line with the procedures followed by the main laboratories from Portugal, Spain, France, Italy and the United States. The standardisation of criteria and methodologies and the critical analysis of the results validate the quality control work from the company’s Quality Department.

The Quality Control of António Almeida Cortiças does not only analyse the finished product. During the process, strict control tests are carried out daily to the cork planks before and after boiling, granulate and discs both before and after disinfection of stoppers in process. The internal laboratory of António Almeida Cortiças is an essential foundation for the continuous improvement program and the search for innovative solutions that meet the needs of an increasingly demanding market. The internal R&D program relies on the participation of external laboratories, universities and colleges, providing the on-going projects with dynamism and technical support. As recognition, António Almeida Cortiças has been awarded with the following certifications:

  • ISO 9001:2008 and ISO 22000:2005 – Integrated Quality Management and Food Safety System by APCER
  • SYSTECODE PREMIUM by Bureau Vèritas
  • Certificate of Conformity PT-BIO-02 by ECOCERT



For António Almeida Cortiças, the quality of the products is not limited to visual grade or the analysis of their chemical properties. In order to guarantee a safe sealing solution, it is essential to analyse organoleptic characteristics of the cork stoppers through a permanent batch control in accordance with a comprehensive framework of sensory tests. The achieved results complement the permanent tracking of the chemical compound 2,4,6-Trichloroanisole (TCA). Cork stoppers are a natural product. Therefore, the unique characteristics of each batch must be taken into consideration. In António Almeida Cortiças, the need to qualitatively enrich the cork batch evaluation is fully consolidated. For that reason, daily investments in human resources and materials are aimed at improving our analysis and control process.

The Company has an analyst team, endowed with high technical skills, capable of developing and applying methods for organoleptic characterisation of different cork batches. In this way, António Almeida Cortiças has a strong historical data structure that allows an efficient action concerning the prevention and rectification of cork batches, a fundamental aspect required to supply excellent products.

A complete understanding and respect of corks’ biological properties are primordial conditions to create a rigorous action plan towards a sustainable quality improvement of our stoppers. Following long years of demanding work, António Almeida Cortiças has today, a quality assurance system that combines a stringent quantitative analysis with a specific qualitative examination, allowing us to provide our Clients closures that ensure safety and reliability.


For António Almeida Cortiças, everything begins in the forest. Extensive knowledge of the reality of the forests as a result of decades of direct and permanent contact with the cork oak forests enables the company to control the entire production process, from the forest to the final finishing of cork stoppers. Hence, António Almeida Cortiças integrates the entire value chain in the business unit.

Its production facilities are supplied with technologically advanced equipment allowing the production of high mechanical and organoleptic performance corks.

In the different production areas, the Company is supported by a strong team of technicians and employees with a sense of responsibility and mission.


In recent years, as a result of substantial investment in R&D and more efficient research processes, we implemented new productive solutions such as:

  • Innovative boiling and sterilisation system of cork planks,
  • System for the disinfection of granulates – AdvanTECH
  • DDisc Disinfection – DEO
