Cooling breezes come through the northwest corridor above and to the west of the Calistoga AVA providing relief during hot summer days. Air movement in afternoons is a result of Mount St. Helena and Palisades “air pump.”
VINEYARD BENEFIT: Breezes cool things down during normally stagnant air-flow periods in other AVAs. Ideal growing conditions with cooling breezes allow for acid retention, better humidity control, mildew control and better structure and age-ability in grapes.
