Calcareous Estate wines are produced from grapes grown at one of our three vineyards.


Terroir & Vineyards


Calcareous sits just 12 miles from the Pacific Ocean and enjoys the full benefits of Paso Robles' unique westside climate. The western edge of the Paso Robles AVA is probably the fastest growing and most sought out land for growing wine grapes in California.  Richly calcareous soils, the regulating maritime influence of both the Templeton Gap and Salinas Valley fogs and steep hillside topography create a spectacular climate for growing wine grapes.

Long, warm days during the growing season, followed by the cool nights, result in a massive diurnal temperature swing that is of utmost importance to producing perfectly balanced wines.  The benefit of this unique AVA, and Calcareous’ special place within it, are a long growing season resulting in perfect maturity. The result is wines of uncommon character and unparalleled beauty.
