Thank you very much for your thought-provoking response. I did spend time looking through the Vinovation website, and I also picked up the recent The Science of Wine by Jamie Goode to get some medium-level descriptions of the processes.
I'm just beginning the research for this article, so I'm not yet on deadline. I'd be happy to set up a time to chat when you get back from South Africa. I live in Oakland, so I can easily arrange to come up to Vinovation to talk to you.
