During the growing season, the vineyard can be subjected to daily highs of 95-110 degrees and lows into the 30's. The dramatic daily temperature swings are the result of the nightly coastal cold air mass from the Templeton Gap. The cool night air at night and in the mornings followed by warm sun that heats the air and vines in the afternoon combine to grow an ultra premium grape.
Our vineyard is perfectly situated in the heart of Paso Robles’ ultra-premium red wine grape growing region. This recently appellated Paso Robles Willow Creek District AVA is home to a plethora of elevation variances. Heath Vineyards consists of predominately hillside limestone/shale slopes that rise from 1000 to 1200 ft over short distances requiring steep slope viticulture practices.
The steep hillsides and river valley base vary in soil type and depth. Heath Vineyards contains 6 acres of valley containing rich river bottom soil with massive limestone boulders 4-6 feet beneath. The remaining 16 acres of mountain side vineyard cater to the Merlot, Cabernet Sauvignon, Syrah and Petite Verdot vines planted in limestone, with minimal topsoil and a massive limestone mountain underneath.
