Climb the old oak tree in the middle of the Haynes Vineyard and you have a direct line of sight across San Pablo Bay to Mt. Tamalpais on the other side. On cool mornings the marine level sinks down into the Coombsville Bowl and doesn’t break up until the afternoon, creating the mildest growing season in the Napa Valley. The vines are planted in deep, alluvial,cobblestone soil ideal for root penetration. Below the topsoil a layer of powdery, white volcanic ash stores tiny amounts of moisture allowing the fruit to maintain tremendous acidity and develop an elegant and refined tannin structure. Haynes produces classic, age-worthy wines of fruit and minerality.
