There's a moment, not long after Porto falls away behind you, when the road opens and the valley appears all at once. Whole hillsides cut into terraces, rows of vines stepping down to the bronze river, the work of centuries that no photograph manages to flatten. This is the oldest demarcated wine region on earth, a UNESCO World Heritage site, and it's still very much alive, with people pruning, harvesting and tasting the way they always have.
We head up the valley slowly, stop at a family quinta where they're expecting us, walk among the vines and sit down to a tasting with the Douro below. We talk with the people who make the wine, from the full-bodied Douro reds to the port that ages quietly in the barrels. And lunch, looking out over the vineyards, tends to be the part people remember most.
