REVO-BOIL utilizes superheated water and steam to deeply penetrate cork planks, effectively reducing TCA levels. Operating at temperatures of up to 120°C, REVO-BOIL consistently achieves maximum purification while minimizing water usage and preventing cross contamination between
batches. The proprietary Ganau Revolution purification process represents the latest stage in the development of traditional boiling methods and is unrivaled in taint reduction.
Cork planks are hand-cut into strips within 24 hours of completing the Ganau Revolution cleaning process, preventing an unnecessary waiting period at high moisture levels which can lead to mold growth and possible contamination. After passing visual inspection, the strips are hand-cut by skilled employees, first into squares and then into cylindrical natural corks. The excess material created during the production of natural corks and discs is subsequently broken down into granules to be later molded into agglomerated corks.
Following the cutting stage, the raw corks and discs are submitted to Ganau’s second cleaning process. Centered on a custom-manufactured system, TECH-FLOW is a disinfection process that effectively removes TCA and other unwanted off flavor molecules from cork using controlled steam and heat flow.
QUANTUM is a chemical-free technology that operates on the principle of thermal desorption. By employing high temperatures of up to 180°C alongside a steam counterflow mechanism, QUANTUM effectively eradicates TCA and other sensory deviation molecules from cork granules – all while preserving cork’s natural properties.
Each cleaning cycle is tested for TCA (through our GCMS’s) before proceeding to the next stage of molding.
Finished cork products are rinsed of any production residue, using water for a natural finish or hydrogen peroxide for a white finish, before being rapidly dried by specialized machines to immediately remove any excess moisture. Corks are sorted first electronically and then by employees, simultaneously dividing the finished corks into different visual classes and eliminating any corks with flaws or critical defects.
Whether order quantities are in the millions or few thousands, Ganau offers cork branding to all of its clients. Ganau can assist in designing artwork, as well as work with clients to execute laser, fire and ink branding that meets their requirements. Fire branding is the preferred method of prestigious winemakers, since the final brand consists of a neutral imprint, whereas ink branding may benefit clients that require complex artwork or a more economical alternative to fire branding. Laser branding is the newer and more precise technology available for both side and cork ends.
In the final step of the production process, all cork products are lubricated using Ganau’s exclusive system, which achieves perfectly even and consistent lubrication for excellent bottling performance, optimal seal and easy extraction. Once lubricated, corks are moisturized, packaged and sealed to ensure maximum quality upon delivery.
Ganau has sustained its long-standing reputation for unparalleled quality by developing industry-leading cleaning and quality control procedures in the reduction of taint from cork closures. Beyond the ultimate goal of eliminating taint, Ganau’s implementation of rigorous quality control standards throughout the production process guarantees consistent performance from its full line of cork closures.
Ganau employs sensory and GCMS screening tests to diligently monitor the presence of TCA in raw and processed cork materials. Ganau soaks thousands of corks on a daily basis, drastically exceeding industry standards in order to study background aromas and TCA concentrations. GCMS tests are performed through production and finished product, ensuring that only the purest corks enter the final production stages.
Beyond TCA screening, Ganau utilizes precision electronic analyzers to measure dimensions, weight and moisture levels of cork products throughout the production process, making certain that the final corks meet both physical and mechanical specifications. Ganau is also well known for its uniform method of grading corks, performed by both specially-trained employees and carefully calibrated electronic eyes.
In applying a wide spectrum of quality control measures, Ganau relies upon modern technology and skilled employees to provide winemakers with some of the purest and highest-quality corks in the world.
Corra Wines
Our vineyard and winery teams strive for perfection at every point from bud-break to bottling. When it comes to trusting a natural cork to keep flavors safe during the rest of the wine’s journey, I need to know that my cork supplier takes as much pride in their product as I do in mine. Ganau seeks the same perfection that I do.

I have been using UNIQ since 2014. I began using them on my SB and have been very happy with the performance. I am now using them on my entire line of wines including our age worthy Cabernet and Bordeaux blend. I would definitely recommend UNIQ to anyone interested in a taint-free, consistent closure for their wines. Scot Covington, Winemaker
Champagne Billecart Salmon
In the continual pursue of perfection, Billecart Salmon accepts only the finest closures for our wines.
For the past several years, we have been working with GANAU both with their traditional corks as well as “UNIQ”, their technical closure, which is keeping us extremely satisfied.
Arnot-Roberts
Our experience using Ganau natural corks for our single vineyard cabernet sauvignons has been outstanding. The look, feel and sensory consistency of the product is unparalleled. We farm, harvest and craft our cabernets with the intention that they will continue to improve for decades in the cellar. Using the best cork in the business is the only choice for us and Ganau makes that choice easy.

Champagne M.Hostomme
GANAU has been our exclusive supplier for more than 15 years. We choose UNIQ for our Cuvée Champagne Blanc de Blancs Grand Cru ABYSSE. The bottles are submerged for 12 months in the Ocean at 60 meters depth. UNIQ perfectly preserved the wine’s integrity even under these extreme conditions.
We have been using UNIQ for several years for its technological qualities, its neutrality, its homogeneity, its innate attitude for a better wine ageing, its extraction consistency and its respect for our Champagne.
Laurent Hostomme
Champagne Vollereaux
Thank you Ganau for the quality you provide us with UNIQ. I have been using UNIQ exclusively for a few years in the entire portfolio of champagne that we produce. My clients are reassured when I tell them that they will not have any corked wine anymore. Uniq provides them with a better sealing, thus a better guard of their favorite champagne.
Franck VOLLEREAUX
Domi corks go hybrid! After several months of testing, we have chosen a new cork: Phénix, produced by Ganau. Although technological corks are increasingly used in Champagne, we have rather preferred Phénix combining the superior performance of a technological cork with the tradition of a nice natural cork disc, rigorously selected in Sardinia. – Stéphane LUTZ
Greg La Follette
My partner, Patrick Dillon, and I conducted an extensive two years cork trial with Alquimista’s most high end wine, Cellar Dreams ($94/bottle). We compared UNIQ with a solid natural cork and synthetic closure.
We love the consistency UNIQ brings in the bottle and the absence of any form of taint. We are now using UNIQ with all of our wines.
Greg La Follette, Winemaker
Meyer Cellars
For aromatic whites and rose UNIQ is the obvious choice. We have not had a single bottle with cork taint.
