About Us / Calera Wine Company History: A philosophy of sustainable agriculture defines Calera's farming practices. In 2008 Mt. Harlan Vineyards were certified organic by CCOF. The dry climate of Mt. Harlan reduces the need for extensive use of pesticides and when the need arises, organic products are used. Calera's one-of-a-kind, multi-level (7 tier), gravity-flow winery built into the side of a mountain allows wines to be moved in the gentlest possible way, by the natural force of gravity.
