Making corks

Spent yesterday morning at Amorim's labs with Dr Paulo Lopes, who's a scientist working on issues such as oxygen transmission by closures. It sounds nerdy and dull, but it's really important. Paulo did a presentation on efforts by Amorim to deal with the taint issue, then he presented his work on how much oxygen ingress there is with each type of closure.

Then it was time to see a couple of cork manufacturing and processing plants. High-end corks are still punched by hand (top picture), a skilled task where rapidly taken decisions about where to punch the next cork from have important quality implications. The corks are then sorted either automatically, or manually (above). The best quality corks can cost more than a Euro each (below) - and they look beautiful. The modern cork production process is a fusion of the modern (e.g. gas chromatography screening for minute TCA levels) with the traditional (cutting cork bark, hand punching corks).

Sounds fascinating.

I would love to visit Portugal, but sadly my commitments (especially the mortgage) do not permit me. Missed out on the MW study trip there last year. I have a lot of friends in the Port industry - and have (possibly unfairly) been connected with the screwcap lobby (have nothing to do with them.)

Actually I was looking at your closure book a few days ago for a piece I was writing on closures generally and wondered whether we could get some more detailed, independent material on cork grading and different types of technical corks. I have been trying to accumulate this material myself, but it is difficult to do from the other side of the world.

Surely if cork is screened for TCA, then cork taint stops being an issue?
