Jancis Mary Robinson - Investment into Wine

Jancis Mary Robinson OBE, MW is a British wine critic, journalist and editor of wine literature. She currently writes a weekly column for the Financial Times, and writes for her website jancisrobinson.com. She also provides advice for Queen Elizabeth II's wine cellar.
As a wine writer, she has become one of the world's leading writers of educational and encyclopaedic material on wine. The Oxford Companion to Wine, edited by Robinson, is widely considered to be the most comprehensive wine encyclopaedia in the world. The first edition was published in 1994, and took five years to write after she was signed on as editor in 1988. In addition, The World Atlas of Wine by Hugh Johnson and Robinson is one of the world's leading wine atlases.
In 1995, Jancis Robinsonn appeared in a 10-episode wine course on BBC 2 television. This series has later been reissued on DVD. A book titled Jancis Robinsonn's Wine Course was written to accompany the series and has gone through several editions.
She has an honorary doctorate from the Open University, and was made an OBE in 2003, among numerous other awards for her writing. Her accolades include multiple Glenfiddich Awards and André Simon Memorial Awards, and a selection as the Decanter "1999 Woman of the Year"

Below is a rough guide to her scoring.

20 - Truly exceptional
19 - A humdinger
18 - A cut above superior
17 - Superior
16 - Distinguished
15 - Average, a perfectly nice drink with no faults but not much excitement
14 - Deadly dull
13 - Borderline faulty or unbalanced
12 - Faulty or unbalanced

She will occasionally give a '+' or even '++' to suggest that they think (but are not 100% sure) that the wine will improve, and if a score comes with a minus attached, it means that it has a drawback, usually described in the tasting note.
