Temecula derives its name from the Luiseno Indian term "where the sun shines through the mist." True to its name, the region is known for the mist that lingers until mid-morning on its 1,400 foot plateau. Temecula is a very warm region that receives little rainfall, which creates a short growing season that lasts from March to September. Fortunately, the vineyard altitudes and Pacific breezes moderate the temperatures, creating cool nights that prevent the grapes from baking in the summer heat and allow them to maintain some of their natural acidity.
The vines are planted in granite and sandy loam soil with good drainage, and the vineyards are irrigated from underground aquifers. Wineries have grown grapes here since 1966, and today over 20 wineries are producing Chardonnay, Merlot, Sauvignon Blanc, Viognier, Syrah and Pinot Gris.
