Place & climate
- Route: South from Bordeaux along the left bank of the Garonne.
- Northern focus: Pessac-Léognan surrounds the city’s southern edge; Graves continues south.
- Sweet focus: Sauternes and Barsac lie around the Ciron–Garonne area. The cool wooded Ciron valley and warmer Garonne help create humid autumn mornings; sunny, ventilated afternoons can then favour noble rot rather than destructive wet rot.
