Terroir

• In the north-eastern part of the appellation area, the dominant bedrock is the Poudingue de Jurançon, a conglomerate of pebbles in a calcareous cement whose weathered outcrops form a stony clay.
• In the southern part of the area, flysch dominates — a sedimentary rock of alternating hard sandstone or limestone beds and soft sandy or clayey beds, tilted by the formation of the Pyrenees with a northward dip that creates east–west-oriented relief.
• Soils most often have a clayey texture and high stoniness, except on north-facing slopes where silt predominates owing to loess deposits.
• The climate is characterised by high annual rainfall of 1,200 mm distributed evenly throughout the year with no dry season, and an average annual sunshine total of 1,900 hours.
• A warm, dry southerly wind of foehn type blows in autumn and spring on roughly one day in three on average, drying the air, ensuring good ventilation, and raising temperatures and sunshine levels.
• The geographical zone covers 25 communes in the south of the Pyrénées-Atlantiques département, to the south and west of Pau.
• Within the conglomerate, the upper reaches of valleys form tight cirques, while the harder rocks structure a landscape of often steep slopes despite modest differences in elevation.

• The vineyard area contracted sharply as a result of fungal diseases, phylloxera, and the two World Wars, falling from 6,000 ha at the end of the nineteenth century to fewer than 600 ha by the mid-twentieth century.
• The remaining vineyard was recognised as a controlled designation of origin for sweet white wines in 1936, then for dry white wines in 1975, with the mention vendanges tardives added to the name from 1995.
• The cooperative cellar of Gan, established in 1949, enabled the survival of many small farm holdings and accounts for 60% of the appellation's total production.

• The wines are characterised by an acidity that balances the alcohol and residual sugars, resulting in wines that are free from heaviness and show great freshness.
• In their youth, the aromas are mainly fruity and floral, then frequently evolve with ageing towards notes of dried fruit and spice, over a timescale ranging from a few years to several decades.
• Wines bearing the mention vendanges tardives, marked by the extended drying of the grapes on the vine during autumn, show a great richness in residual sugars and more intense aromas.

• The steep-slope and cirque topography creates local climates of high sunshine, warmth, and low humidity that promote ripeness and over-ripeness in the grapes, exploited through successive selective harvesting passes.
