Soil and Climate
"The rocky schist soils together with the hot, dry summers produce rich and powerful wines"
Quinta de La Rosa is situated in the Cima Region of the Douro Valley which lies inland to the east of the Serra do Marao mountain range. The region is protected from the rains blowing off the Atlantic and the climate is considered to be a continental climate with hot, dry summers and cold winters.
The majority of the rain falls between November and April with the occasional thunderstorm in the summer months. Annual rainfall is generally low with an average of approximately 700mm in Pinhao. The winters are generally cold and wet with temperatures averaging 4ºC while the summers are hot and dry with temperatures reaching an oppressive 40ºC or more. We commonly have afternoon winds which funnel through the wind cooling and drying the vineyards so helping to minimise any potential fungal diseases on the grapes such as bunch rot.
As the vineyards of La Rosa only reach a maximum altitude of 400m we have few frosts but at higher altitudes frosts are frequent which can cause damage to the vine's young shoots in the early spring. Hailstorms can sometimes occur and are most destructive especially late in the season when the grapes are soft and susceptible to damage. In July and August very localised hail and thunderstorms can be disastrous especially at higher altitudes.
The soil of La Rosa's vineyards, as elsewhere in the Douro Valley, is made up of schist, a slate like metamorphic rock. Very flaky and ochre in colour, the schist soil is rich in nutrients and free draining requiring the vines to grow their roots deep into the soil, down through fissures in the bedrock, in order to find water. The combination of the hot, dry climate and rocky soils results in low yields of concentrated berries - ideal for producing La Rosa’s complex and rich wines.
