The Douro Valley — A Day
Among the Terraced Vines

The first thing the valley teaches is the scale of the work. The terraces — socalcos, the Portuguese call them — climb the impossibly steep schist slopes in their thousands, narrow shelves held up by dry-stone walls, each one cut and built and planted by hand because no machine could ever work ground this vertical. Some are the old, tight, single-row terraces of the eighteenth and nineteenth centuries; others the broader post-phylloxera rebuilds; all of them the product of a staggering, centuries-long human effort to make a near-vertical gorge produce wine. The result was protected in 1756, when the Marquês de Pombal drew a boundary around it and made the Douro the first formally demarcated and regulated wine region in the world — the great-grandfather of every appellation since.

A guided day brings the traveller onto one of the quintas, the wine estates that work the slopes, and the visit makes the abstraction concrete: the vines clinging to the terraces, the schist crumbling underfoot, and — at the older quintas — the lagares, the broad shallow granite tanks where, at harvest, the grapes are still trodden by human feet, a line of workers treading arm-in-arm late into the night to a rhythm and a song. It sounds like folklore and it is simply how the best port is still made, because nothing presses the grape as gently as a foot. Standing on a terrace with the river a long way below and the walls marching up the slope above, the wine the traveller has been drinking all week stops being a product and becomes a place.

Then the reward for the climb: the tasting. At the quinta, the day's wines are poured with the valley spread out below — and the Douro pours two stories now. There is the port the region was built on: the white and the ruby, the nutty aged tawnies, the great vintage ports that sleep for decades, all of it fortified and sweet and built to last, the wine that the rabelo boats once carried down to the Gaia lodges to age by the cool river. And there is the newer story the valley is proud of — the Douro table wines, the dry reds and whites now made from the same old terraced vineyards, which have quietly become some of the most exciting wines in Portugal. To taste them side by side, where they're grown, is to understand the region as a living place rather than a museum of port.

Lunch, on a good tour, is taken at a quinta table on a terrace above the river — grilled meat or bacalhau, the estate's own wine, the gorge dropping away below, the heat held in the schist and the silence enormous. It is one of the great meals of the trip, not for any single dish but for the setting: eating the food of the valley, drinking the wine of the slope you're sitting on, with the whole hand-built landscape laid out in front of you. This is the lunch the entire region was, in some sense, built to make possible.

The Douro is a river before it is a wine, and no day in the valley is complete without getting onto the water. From Pinhão — the small town at the valley's heart, its train station famously tiled with blue azulejos showing the harvest — a boat takes the traveller out onto the river for an hour or so, often in a rabelo, the flat-bottomed wooden boat that for centuries carried the port barrels down the rapids to Gaia before the dams tamed the river. From the water the terraces rise on both banks in their full improbable sweep, the quintas' names painted white on the hillsides, the reflections doubling the whole thing in the green water. The dams have made the Douro placid now, a string of calm reaches behind locks, but the shape of the working river is still everywhere — this was a highway of wine long before it was a view.

And then the long road back down to Porto in the late light, the gorges unfolding in reverse, the city's lights coming up along its own stretch of the same river. The day closes where the week's Porto evenings closed — at the table — this time at DOP, chef Rui Paula's restaurant in the old town, with a bottle of the Douro red just tasted at its source. The loop is shut: the glass on the Gaia terrace, the hillside that filled it, and back to the city with the whole story finally in order.
