I'm still flat out on the current book project but thought I'd post this link to a report in The Drinks Business on the latest figures on the extent of organic viticulture in France which now accounts for nearly 6% of total wine production.
More interesting is the rate at which the rate of conversion is speeding up. According to Elizabeth Mercier of France Agence Bio at Millésime Bio in Montpellier last week Languedoc-Roussillon’s organic vineyard coverage increased by 51.9% from 2008 to 2009 (the last date for which statistics are available), Rhône-Alpes by 50.8%, Aquitaine by 45.2%, Burgundy by 43.2% and Provence-Alpes-Côtes d’Azur by 34.6%.
The report points out that growth was slower in the Loire and Alsace (7.1% and 13.5% respectively over the same period) but doesn't take account of the fact that those regions already have a significant number of organic and biodynamic producers.
There are also current figures for Italy and Spain.
Whilst on the subject of France I've found a new site, Club du Vin Authentique which has a very interesting - and alarming - feature on the level of pesticides in conventionally produced wine. (In French, I'm afraid)
