Jancis Robinson was on Charlie Rose this week. (TiVo makes it hard to figure out when shows are actually on!) She mentioned two wines that she had tasted when she was in Canada recently. The first was a wine made in 1892, and the second was one in the 1790s (something about the bottle having been Napoleon's at the Battle of the Bulge. Amazing.
Since Charlie's crew didn't seem to think that her portion of the show was as important as his interview with Madeline Albright, and thus is not available on the web.
BTW, Jancis Robinson's Oxford Wine Encyclopedia is on my wish list.
