ProCork to showcase new cork technology at WineTech

ProCork will be showcasing its new cork technology on Stand 316 during WineTech - The Australian Wine Industry Trade Exhibition to be held at the Adelaide Convention & Exhibition Centre, from July 29 to August 1, 2007.

According to ProCork, a special membrane in its new cork helps to reduce taint and control oxygen permeation into the wine.

On its stand, ProCork will display some of the award winning wines using ProCork, some of which will be available for tasting. Also on display will be wines sealed under different permeability closures for comparison tasting.

ProCork’s membrane technology is said to be the ideal solution for winemakers looking to balance consumers’ preference for cork with their own expectations for consistent, quality wine.

The membrane-based technology involves the application of a thin, transparent five-layer membrane to the ends of natural or technical corks, which acts as a barrier to TCA and glue transmission from the cork to the wine.

This membrane also prevents the cork ‘scalping’ volatile components from the wine and acts as an oxygen membrane.

The important role of the oxygen membrane was reinforced with the recent publication of a study by Australian winemakers and the ProCork technical team. The study concluded ProCork was shown to allow wine to develop without excessive development of reduced or oxidised characters.

“The membrane technology was shown to perform better than the screw cap and other cork-based closures because it retained the highest averaged levels of free SO2 and fruit characteristics without the higher levels of reduced characters seen in the screwcap control or oxidised characters seen in the cork controls,” the study found.

“The results show that the membrane technology use in the trials here will allow winemakers to optimise oxygen permeation post bottling and obtain bottle development uncompromised by oxidation of excessive reduction.”
