Claiming thinning cork could ultimately lead to a bad bottle of wine. With the character of wine corks in question, sixth generation winemaker   has his sights on screw-caps.

Here’s what the study claims:

  • Research led by University of Lisbon says quality of corks is decreasing
  • They say this is due to thinning bark on the trees that produce wine corks
  • Quercus suber trees have seen a drastic decline in quality in 20 years
  • Thinner bark means the corks are worse at keeping air out of bottles
  • The researchers say this could be because they are protecting themselves against increasing ultraviolet radiation resulting from climate change
  • This has caused the bark to thin to just 10% of what it used to be
