Below is my best shot at an electronic representation of Bill Blatch's diagram of the day by day progression of picking in the 2007 harvest in Bordeaux. My apologies for the wiggly lines (Julia, on holiday, would be horrified) and the occasional wobble. I hope you can make sense of it nevertheless. Note that the numbers in the Sauternes 'column' refer to which trie, passage through the vines to pick, was taking place at that point. See the key to symbols and footnotes at the bottom of the table – JR.
