Natural Cork


in Natural Corks & TCA Taint-Free Technical Corks 

Exclusively available at Cork Supply, the Pure Cork & Innocork Circuits helps reduce the risk of sensory defects in natural corks caused by TCA or other off aromas. The Pure Cork & Innocork Circuit is a patented process by which potential TCA and other off-aromas are extracted from natural cork using a water vapour & ethanol mixture under controlled temperatures. Every natural cork and disc produced by Cork Supply is processed with the Pure Cork & Innocork Circuit. 100% of the granules used in the production of micro-agglomerated corks and technical corks are processed by VAPEX®. The disinfection process effectively extracts TCA and other off aromas from cork granules by using pressured steam. The disinfection process is done by batch, the batch system also allows for full traceability.


As part of the commitment at Cork Supply to our clients, we are the first company in the industry to institute a "Bottle Buy Back" guarantee.  If you receive a cork taint claim on any bottle sealed with our DS100 or VINC corks, we will buy the bottle back at the retail release price of the wine.

For centuries, natural cork has been the closure material of choice for quality wines. Lightweight, inert, impermeable to liquids and gasses, compressible and elastic, natural cork is time-tested and proven to effectively seal glass bottles — protecting wine from oxidation while enabling optimum oxygen transfer needed for wine to mature. The remarkable physical and mechanical properties of natural cork make it an ideal closure for all winemaking styles, grape varietals and desired ageing. 


Natural cork is also 100% renewable, recyclable and biodegradable. Cork production is eco-friendly and sustainable. Punched from renewable, responsibly harvested bark of the cork oak (Quercus suber), no trees are cut down. Corks have the smallest carbon footprint of any standard wine closure, and the forests they use help preserve our planets critical ecological services, reducing CO2 greenhouse gasses from our atmosphere while sustaining an abundance of fragile habitat and wildlife. 


Cork Supply improves on Mother Nature's perfection, using applied innovation and exacting standards to deliver the highest benchmark of consistency and quality assurance at every step from forest to bottle. In addition to ensuring the corkwood we use to produce our corks passes industry-best TCA-testing requirements, every natural cork we deliver has the critical added advantage of Innocork®, our patented extraction procedure that uses steam and ethyl alcohol to effectively volatilize potential TCA (and other off-aromas) molecules from the cell structure of natural cork. This unmatched combination of quality, performance and sustainability makes natural cork from Cork Supply the natural choice for wines of the 21st century.

Nobispark Bidule
Nobispark Bidule

The search for the finest balance between the natural compounds of oak and sparkling wines during alcoholic fermentation has led us to develop NOBISPARK. This oenological bidule is the result of a project to develop the use of oak during the second fermentation. Used in the same way as a classic bidule, NOBISPARK does not require any specific equipment when it is inserted after filling the bottle.

  • Nobispark Fresh Bidule will enhance and “clean” the fruitiness of the base wine without adding any toast character, it is neutral. Aromatic complexity.

  • Nobispark Sensation Bidule keeps the fruit while adding sweetness, light vanilla & toasted notes; brings a slight oak character to the wine.

Time of ageing is a minimum of 4 months -12 months, but can also go beyond 12 months. Dosage for 1 Nobispark is 0,7g/L.

Toast options are Nobile Fresh (untoasted) or Sensation. Packages of 500
