Making new patamares vineyards at Quinta da Vila Velha

Graham’s Quinta da Vila Velha is in one of the Douro’s prime locations for growing top quality Port grapes. It is almost directly opposite Graham’s Quinta dos Malvedos but with its northerly aspect (being on the south side of the river) it produces wines with a distinctively different character from those of its neighbour.

For the last few months Mário Natário, Graham’s viticulturist managing this estate, has been overseeing the construction of the new earth-banked terraced vineyards, called patamares in Portuguese, which are being constructed in the vineyard parcel known as Merouços, high up near the top of the ridge.

We have decided to plant new Touriga Nacional vines in this parcel in the first few months of this year. This is partly because there is not currently a lot of Touriga Nacional planted at Vila Velha but chiefly because this particular parcel of vineyard has the potential to produce remarkable Touriga Nacional grapes.

The quality of this vineyard is immediately apparent from the colour of the soil. It is much darker, richer in organic matter and higher in clay content than many other vineyards in the region. It is at a relatively high altitude for a Douro vineyard at an average of 300 metres.

At this altitude, with the slightly cooler conditions and northerly aspect of the vineyard, the Touriga Nacional will achieve lighter, more fragrant and more aromatic characteristics compared to the richer and riper qualities that the same variety achieves in low-lying parcels next to the river. The difference really is astonishing when the two are compared in a blind tasting.

This parcel will therefore add a new component to the array of wines from which our winemakers make Graham’s Vintage Ports. The wines produced from this vineyard will bring more ethereal notes, complementing the opulence of the wines from Graham’s other great vineyards and enhancing the harmony and complexity of the wine.

The quality of Vila Velha’s vineyards is such that when the Symington family joined forces with Bruno Prats of Bordeaux to make the premier wine Chryseia and its second cousin Post Scriptum, Mr. Prats specifically chose selected parcels of Vila Velha’s vineyards for the Chryseia each year.

Tracking the Season – 19th July

This year what is readily apparent at this stage in the season is the generally healthy appearance of the vines — not just the homogeneous, lush green foliage but also the perfectly formed clusters of berries showing varying stages of development; some still almost entirely green, others already changing colour, whilst others at a more advanced stage of ripening with almost the whole bunch displaying the blue-purple tones of the varieties that turn colour more precociously such as the Touriga Franca and Tinta Barroca. This is the beginning of the ‘pintor’, (literally ‘painter’ in Portuguese), the stage in the annual cycle of the vine known as ‘véraison’ when ripening of the grapes begins in earnest as the sugar content in the berries begins to rise steadily.

Alexandre Mariz, the Quinta dos Malvedos and Quinta do Tua viticulturist informed us that the pintor began about a week late, in step with the generally later vegetative cycle of the vine this year, which as he explained can be largely attributed to the generally cooler conditions experienced during the first half of 2013. However, this is of minor concern to Alexandre who is upbeat about the prospects for a good year. He pointed out the very encouraging progress of the ‘atempamento’, the process whereby the vine stems and stalks transition from the vivid green ‘herbaceous’ stage to a red-brown woodier colour (becoming less sappy and more rigid). This is always a sure sign of quality, revealing that the plant is filtering water more sparingly to the clusters of berries which will lead to greater concentration and ultimately, higher fruit quality.

Alexandre commented that he has often been reminded this year of how things used to be many years past, when the seasons were more clear-cut and the vines’ annual development cycle followed a more predictable and even pattern. He told us that the ‘maias’, small yellow wildflowers (yellow broom), which normally appear in May (hence the name ‘maia’ from ‘Maio’ – Portuguese for May), did actually bloom in May, whereas over the last few years they have often arrived precociously in February or March, ‘duped’ by earlier than normal spring conditions.

The two replanted vineyard plots at Malvedos are looking splendid; the bench-grafted vines planted in March are prospering in their mountain vineyard environment. Alexandre was visibly satisfied by how well the new plantations have been settling in, helped along by some drip-feed irrigation, which is allowed during this early stage of the vines’ life in order to help them get established. At the northwestern edge of the Quinta, at approximately 350 metres (1,150 feet), where we have planted four hectares of Touriga Nacional and two hectares of Sousão, the newly sculpted terraces, known as patamares, looked impressive and one wonders at the skill of the hardy men and women who shape them out of such steep slopes.

Alexandre is pleased with the drainage ditch, which will collect and channel excess (rain) water, which would otherwise contribute to erosion – one of the toughest challenges we face in our vineyards in the Douro. The terraces are canted slightly inwards towards the hillside to retain some rainwater, whilst also moderately arched along their length so that excess water can run off and gather into the drainage system.

Alexandre took the time to share some of his deep knowledge of the Douro’s vineyard environment. He provided some fascinating insights on the schist soil and how it creates the unique identity of the Douro’s wines. Schist is formed into laminated layers with many fissures and cracks which eventually crumble into loose rocks of varying size and also over time into a fine dust. This allows the vines’ roots to progress deep into the soil in search of water and moisture. The strata at varying angles have many fissures along which rainwater collects and is evenly distributed, and thus the schist acts as a water retainer and distributor. The vine roots not only develop downwards but also across (along the fissures) to tap as much available moisture as possible.

Schist is also a temperature regulator. The mica (a shiny silicate mineral) present in the schist refracts much of the sun’s powerful rays creating a twofold effect; first, heat is radiated off the stony surface upwards into the vines, contributing to the grapes’ ripening and, secondly, this deflected heat means that the temperature of the subsoil is lower than at surface level. Importantly this translates into less evaporation, conserving the moisture in the soil that sustains the vines over the long hot months of the ripening season. Alexandre illustrated this phenomenon by digging just a little into the soil and grabbing a handful of soil, which he formed into a moist pasty cake in his palm. Considering we’re in the second half of July with midday air temperatures well over 30ºC, this really demonstrated the point.

The old west-facing stone terraces at Malvedos (opposite the ‘Port Arthur’ vineyard) suffered damage from a fire started by sparks from a passing preserved steam locomotive 3 years ago. Next year we plan on replanting these terraces with Alicante Bouschet and Touriga Nacional.
