Three climate anchors
- Atlantic west: Bordeaux and the western Loire illustrate maritime influence: moderated temperatures, rainfall and important harvest-weather differences.
- Inland and eastern vineyards: Burgundy, Champagne, Alsace, Jura and Savoie have varying continental and mountain influences; frost, exposure and altitude matter.
- Mediterranean south: Southern Rhône, Provence, Languedoc, Roussillon and Corsica illustrate warm, often dry summers; wind, hills and water reserves create local contrasts.
