The vineyard can be subjected to daily highs of 95-110 degrees during the growing season, yet the nightly coastal cold air mass from the Templeton Gap is responsible for the incredible day/night temperature swings of up to 70 degrees from the hottest to the coolest parts of the vineyard on a daily basis. Thick fog rolls in early in the morning cooling the grapes. Warm sun then heats the air and vines in the afternoon 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 creating mountain vineyard influences.
Mountain side and mountain valley vary in soil type and depth. Heath Vineyards contains 6 acres of mountain 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.
