Production is expected to increase 10% in this region. The dry winter contributed to the destruction of many areas due to downy mildew, nor did the cold spring favour this. The sudden differences in temperature caused some problems to occur (especially in the Loureiro variety). Greater production is expected for the Arinto, Alvarinho and Fernão Pires grape varieties.
DOURO & PORTO
An increase of production is expected in the Douro and Porto region (30%). The downy mildew manifested itself with little intensity and did not generally affect the production. The climatic conditions, especially in June with high relative humidity and overcast days, contributed to the spread of the powdery mildew, but without significant impact on the production. The slight advance in the vegetative development will imply a harvest on normal dates, with a good quality expected.
TERRAS DO DÃO
In the region of Terras do Dão production is expected to increasen by 35%. The vines, in general, are in good health with well-developed berries. Some outbreaks of powdery mildew have occurred due to mild temperatures, light showers and dews in June. The plant cycle is within the normal range for the region.
