Temecula Valley Terrain (Back to overview)

It is safe to say that Temecula wine is produced in an entirely man-made viticultural area. The terrain of the region is very dry, and there is little natural vegetation. Irrigation is absolutely necessary for grape growing and subsequent wine production.

The Effect of Soil & Terrain on Temecula Grape Growing

Most vineyards are planted at elevations between 1,400 and 1,600 feet above sea level. The soil is comprised of coarse sand and decomposed granite. It contains little organic material and drains very well. Erosion of the top soil is a constant issue, and low-lying vegetation is commonly planted to preserve this precious commodity in and around vineyards.

Although Pierce’s Disease has historically been a problem in the region, progress has been made in alleviating this scourge. Temecula wineries make a number of distinguished wines and have inviting tasting rooms.
