PORT Flashcards
Describe the early history of Port (1600-1800s) (6 points)
1600s:
- Trade war btwn England and France caused England to trade w/Portugal, starting with big reds, which were eventually fortified with brandy to stabilize for travel
- 2 British Merchants tried a sweet style at the Abbot of Lamego and preferred it, leading to fortification happening mid-ferment and large qtys sent to England
1703: Methuen Treaty led to lower duty in England vs other countries. Production increased, quality fell via poor spirits/elderberry juice colour, and demand declined
1756: The PM Marquês de Pombal demarcated the vineyards and created the “Real Companhia Velha,” which sold all exports, fixed prices, and supplied spirit. Sales and prices rose again.
1800s: Challenging due to Peninsular war, civil war, phylloxera and mildew.
Consolidation began as shippers acquired many estates at low prices.
Describe the later history of Port (1900-Present) (10 points)
1933: Instituto do Vinho do Porto (IVP) formed to admin and supervise the industry
1932: Casa do Douro founded to supervise growers in Douro
- Both the above authorities controlled the aguardente purchase
- Just after: parcels rated A–I based on Port suitability
1980s: World bank scheme offered low interest loans to plant or replant up to 10ha of A or B graded land, if 5 specific varieties used, leading to 2500ha more planted on patamares
Shippers and University formed a research program
1986: Portugal joined EU
1991: Producers were sourcing own aguardente, improving quality
1990: Casa do Douro bought 40% of Royal Oporto, the largest shipper, in attempt to allow growers to trade, but it failed and CdD went bankrupt
2003: Instituto dos Vinhos do Douro e o Porto (IVDP) formed for Port and Douro producers
What are some recent changes/trends in the landscape of Port? (2000-Present) 4 points.
1) Improved patamares
2) Other local varieties being promoted
3) Foot treading/manual labour declining due to depopulation in rural areas
4) New technology and improvements replacing the need for manual labour
Describe the size, location, topography, climate and weather for Port. (5 points)
The Douro region which is 250,000ha, of which 32,000ha is planted for Port (of 43,000ha planted).
Climate is warm, continental.
Hot temps up to 40C in summer, mild/rarely freezing in winter.
The Serra do Marão mountain shields the region from the coast and rains
The region follows the path of the River Douro and its tributaries, providing a range of terrain and microclimates.
What are the sub regions in the Douro, what is the difference and weather and what styles are generally grown there?
1) Baixo Corgo - coolest, wettest at 900mm/year. Mostly Inexpensive Ruby & Tawny
2) Cima Corgo - warmer/drier at 700mm/year. Most well known producers have sites here - and most age-indicated Tawny’s and Vintage ports are grown here.
3) Douro Superior - hottest/driest at 450mm/yr (drought an issue). Sparsely planted but increasing, flatter for mechanization.
Describe the soils and irrigation for Port.
Stony, shallow, free-draining, poor nutrients, which limit vigour
Underlying schist bedrock with vertical splits that allow vines to penetrate deep for water. The schist boundary forms the basis for the demarcation.
Irrigation is only permitted in extreme circumstances
Describe the 3 vineyard layouts used in the Douro, their density and pros/cons.
Slope (often >30%) limits layouts to:
1) Socalcos - narrow terraces with walls of dry rock
- Best density @ 6,000v/ha
- suited to steep slopes
- UNESCO protected, can’t be altered
- Walls must be maintained
- Not suited to mechanization
2) Patamares - terraces supported by steep earth ramp/slope
- Low 3,000-3,500v/ha, the slopes take up a lot of space
- Cheaper to implement and maintain vs Socalcos
- Small tractors can run up a diagonal track
- suited to steep slopes
- Erosion and weeds can be problematic
3) VInha ao Alto - vertical planted rows down slopes
- Decent density at 5,000v/ha
- Least expensive to establish and maintain
- Mechanization can only be used if <40% incline
- Water run-off and eroson are problems
Overall, Patamares are preferred.
What is the training/trellising system, canopy mgmt, rootstocks and replanting focus in the Douro?
Cordon & Spur pruned or Head & Cane-pruned, with VSP for mechanization and even exposure/ripening
Summer pruning and leaf removal for exposure is important.
Drought tolerant rootstocks are used, Rupestris/Berlandieri hybrids.
Currently there is focus on vine density, vineyard layouts that allow for mechanization and selection of suitable varieties and rootstock.
What are the max. and avg. yields for Port?
Max. 55 hL/ha; Avg is lower at 30hL/ha due to water availability, hazards
What are the hazards in the Douro and what are treatments? 5 points.
- Late Spring Frost (@ high altitude)
- Cool, wet weather early summer disupting flowering/fruit set
- Downy and Botrytis (esp in Baixo); Fungicides, VSP
- Soil erosion - Fertilisers, cover crops
- Weeds on Patamares - Herbicides
Overall: organic/sustainable farming
What is the timing and method of harvest for Port?
Mostly by hand due to terrain, though Symington estates is developing a new machine harvester in light of the depopulation in the area.
It is spread over several weeks, starting in Superior and ending in Baixo

- Most widely grown variety
What are the characteristics of Tinta Roriz? (4 points)
Aka. Tempranillo
- Early ripening, better in cooler sites
