This canny new map of Loire Valley wine regions has been put together for the Belle France website, who provide walking and cycling holidays. They've certainly done their homework – using the seventh edition of The World Atlas of Wine, they tell us – and the result is pleasingly clickable. You can explore the map by area, appellation, grape type and wine style, and useful information on individual estates can be toggled on and off via the top-centre button.
The map is embedded below, and you can see the original, full-size version here.
