Scientific trials have shown that screwcaps outperform all other closures, including cork. Doesn’t that confirm they are the best closure?
Scientific trials such as the AWRI’s comparative closure trial have concluded that there is no such thing as a perfect closure.
“No one closure tested in this study could be considered entirely suitable by all criteria assessed, for the long term storage of wine.”
AWRI media release, ‘First results of the AWRI wine bottle closure trial published 12 July 2001’
Corks, especially Twin Top, performed at or near the top on all key parameters, without the presence of sulphide-like odours or premature oxidation. Even after 63 months, Twin Top continues to perform well.
According to the former director of the AWRI, Professor Peter Hoj, all closures can be improved:
“All could perform better: cork producers needing to go further in reducing taint; screwcap producers having ‘a long way to go’ to improve liners and gas exchange, and also in preventing damage to caps when knocked; and synthetics are still considered to ‘scalp’ flavour from wine”
Prof. Peter Hoj, quoted in ‘Australia pulls out the stoppers’, Chris Snow, Herald Sun, 11 September 2004, p94
Are screwcaps as close to a perfect seal as it is possible to get?
No closure is perfect, as the AWRI comparative closure trial concluded, and it would be irresponsible of any supplier to claim perfection for their product.
Cork has been doing a remarkably good job for centuries. In fact, as we learn more about post-bottling wine chemistry, we can only marvel at the unique contribution cork makes to wine preservation and development.
As we understand it better we are able to further improve its performance.
