pioneers of Mt. Harlan ava
Mt. Harlan is its own American Viticultural Area (AVA), which is a designated wine grape-growing region distinguishable by geographic features. The Mt. Harlan AVA was approved in 1990. At 7400 acres large and1800 feet minimum elevation above sea level, Calera’s Mt. Harlan vineyards are the only vineyards in the AVA.

Certified Organic
In 2008 the Mt. Harlan vineyards were certified organic by California Certified Organic Farmers (CCOF) for organic farming practices.
Like much of California the summer growing season is very dry which reduces the need for pesticides. Instead, beneficial insects to reduce pest bug populations, compost mixtures to enhance the organic content of the mountain soils, and cover crop methods to improve soil nutrient levels are natural ways to combat any viticultural problems. A dedicated vineyard crew makes multiple trips through the vines on a daily basis to ensure appropriate vineyard management to produce the best fruit possible. The fruit of their labor is precious with crops rarely exceeding two tons per acre, emphasizing quality over quantity.

Calera’s vineyards soar at an average of 2200 feet above sea level and are cooled by the direct flow of cold marine air off the Pacific Ocean through the Monterey Bay coast, towards the upper elevations of the Gabilan Mountain Range and Mt. Harlan. The elevation further moderates the climate in what many expect to be a hot growing region reducing the temperature about three degrees for every 1000 feet of height in elevation.
