Terroir & Character
Climate
Continental desert climate with extreme temperature swings. Summer days reach 35°C+ but nights plunge to near 10°C, preserving natural acidity. The Cascade rain shadow keeps rainfall minimal. Winters can bring Arctic air, occasionally causing vine damage.
Terroir
Basalt bedrock from ancient lava flows underlies the entire region, covered by deep layers of loess (windblown silt) and Missoula Flood sediments. The diverse soil layers, from sand to silt to cobblestones, create remarkable site variation within a single AVA.
