Everywhere else, the planning question is what time. In the Douro it is what week. The vindima — the harvest — runs from roughly early September to mid-October, later in the Douro Superior than in the Baixo Corgo, and it is the only time the terraces have people working on them and the quintas smell of fruit rather than of stone. Outside it the valley is beautiful and empty; during it, it is a working agricultural region and every estate is busy, which means access is arranged rather than assumed and September weekends are booked a year out.
The landscape itself is terraces cut into schist, which is a UNESCO World Heritage cultural landscape and has been since 2001 — worth knowing not for the badge but because it is the correct description: this is a place people made, not a place that happened. The frames are the long views from above at São Leonardo de Galafura, and the river itself at Pinhão.
