As mentioned on the previous page, the Toro wine region has been quite resilient in the face of blights such as phylloxera. Experts say the reason Toro has been able to avoid this pest is because of its dry, sandy soils. In the southern part of the region, it is typical to find clay below the sandy soils. In the northeast, there are some limestone soils. All these soil types are perfect for growing the Tinta de Toro, since its roots can reach into the soils for moisture [source: Vinophoria].
Aside from the soils, the Toro wine region has other aspects that factor into the area's great viticulture. The Rio Duero creates a floodplain in the Toro region, which can provide the area with essential water. The Rio Duero plays an important role in the vineyards since the region cannot count on rainfall too often. Per year, Toro receives an average of 13 inches (35 cm) of rain [source: Wine Country Getaways].
The vineyards are usually at high altitudes, around 2,034 to 2,450 feet (620 to 750 meters). It's the height that gives the vineyards cool evenings during the summer, despite having long, hot and dry summers. Winters are cold, with temperatures reaching as low as 12 degrees Fahrenheit (-11 degrees Celsius). Toro can also claim 2,600 to 3,000 hours of sunshine annually, which gives the grapes a chance to ripen properly.
