Following a kind of tradition that we started in 2007, the first maturity control of our grapes was carried out on August 10th. With a temperature of 43º, my sister in the beach, the sun on my back and the river down in the valley but not at an approachable distance, I wondered why I decided to live in the Douro. Not even the grapes were of any help to hydrate me, as they are still unripe and acid. Some berries are still green, specially Tinto Cão and Sousão. And that was the big conclusion: maturity is late. As sugar levels are still low, with an average potential alcohol of 10.05%, grapes need at least four more weeks in the vines. We should not start harvesting in Quinta Vale d’Agodinho before September 20th.
Alcohol on August 10th Harvest starting
2007 10.49% September 19th
2009 11.86% September 14th
2010 10.05% ?
The biggest contribution for this delay in the maturation comes from the very cold Winter we had. Budbreak and flowering both came later than usual, and so will the harvest. Another interesting thing I noticed that shows pretty well how the Winter and Spring were in terms of rainfall, was the vigor of the shooting. The high levels of humidity in the soil helped the vines to grow more branches and leaves than they normally do. All these shooting has been controlled and cut to focus the vine in the maturation of what is really important: the grapes.
Is there any question you'd like to be answered about winemaking in the Douro valley?
