Independent Trials
- AWRI Closure Trial
Wine was aged in Procork, cork and screw cap in the independent AWRI commercial closure trial. The wine bottled with Procork had improved bottle aging compared to screw cap because Procork inhibited the development of negative reduction odours (eg rubber and sulphur). The wine bottled with Procork also had improved bottle aging compared to cork because Procork inhibited the development of oxidized characters

The sensory analysis results show more homogeneity with Procork. The trends are going in the direction of greater homogeneity for Procork compared to traditional cork. These tests appear to confirm the interest in Procork because of a desire for greater uniformity than traditional corks can provide.
- José Armendariz Laboratory Trial
In a tasting of 50 bottles bottled with Procork, no bottle had any organoleptic deviation including being tested for 2,4,6 trichloroanisole. In the fifty bottles the evolution was very homogeneous. The wine showed an open character with ripe fruit aromas primary and tertiary aromas with hints of vanilla. No reduction was detected, and the wine was in optimum condition for consumption.

"I've done a number of comparison tastings of the same wines sealed with ProCork and either natural cork or screwcaps. This is ... simply (an) anecdotal report. In comparison with natural cork-sealed wines the ProCork-sealed wines have been a bit fresher and more appealing. There's been a noticeable difference in each case. But it's the comparison between screwcapped (tin lining) wines and ProCork-sealed wines that is the most telling. This is when low level reduction in the screwcapped wines becomes apparent: in some cases it is a smoky, minerally twist; in other cases it can be more rubbery and stinky. The reduction leaves a bit of bitterness on the back of the palate of both reds and whites. This feature seems to be most evident in wines that have been in the bottle for 18 months or longer. In comparison, ProCork wines tend to have cleaner, more elegant fruit. The difference is there...."Download PDF: Jamie Goode - Wine Bottle Closures
