Unfortunately they never do any tests with the wines I like to age. Pulling some bottle from S. Africa from the 80s doesn't give me much confidence -- what's their aging track record? Give me a '78 Chave in screwcap and cork -- serve it to me blind and let me judge. I'm certainly not against screwcaps I just don't want them messing with the way my wine tastes. Maybe some say it's better and "fresher" but that might not be the style I prefer.

They will need to do similar experiments in Burgundy, Rhone and Bordeaux before they will be able to convince high end wine buyers.
