Terroir
Natural factors
- A single right-bank slope along the Loir, roughly 5 km long, with gradients of approximately 15% and elevations between 70 and 120 m, covering parcels of around 50 ha in total
- Shallow, stony soils over Turonian tuffeau and Senonian clay-with-flints, with occasional Eocene deposits or Loir alluvium
- Degraded oceanic climate; the Loir acts as a thermal buffer; average annual rainfall approximately 680 mm (via Wikipedia · CC BY-SA 4.0)
- The appellation is restricted to 2 communes (Lhomme and Ruillé-sur-Loir, now merged into Loir-en-Vallée), lying entirely within the Sarthe département
- The slope is broken by 3 small valleys; erosion exposes the bedrock, allowing the soils to warm rapidly
