Portugal History and Business
The Growing Environment in Portugal
Latitude: 38 - 42N
Influences:
- Atlantic –> cool, rainy weather
- Mountains –> protection –> continental inland
- Latitude –> warmer dryer south, rolling hills and plains
Soil: varied
- schist / granite: mountains (Vinho Verde, Douro, Dao, some hilly areas of Alentejo)
- varied: clay / limestone / sandy: coastal (Bairrada, Lisboa, Tejo, Peninsula de Setubal)
- fertile alluvial: riverbanks (fe Tejo)
Areas in Portugal
Vineyard Management in Portugal
Training:
- mostly cordon or replacment cane with VSP trellising
- some old bush vines (Douro and Alentejo), often field blends
Irrigation: allowed for quality (some regional restrictions)
Low organic certification (2%), often organic practice but not certified
Grape Varieties in Portugal
Winemaking in Portugal
EU –> Modernisation of winemaking practices and equipment
–> protective winemaking (SS, Temp control –> fruity wines, better whites)
–> destemming equipment and French oak use –> better red wines (tannin management)
Some traditional techniques, fe
- lg portuguese oak and Brazilian hardwood (3000-6000l) toneis, fe Bairrada,
- less oak use, some foudres (2000-5000L),
- fermentation and foot treading in lagares (shallow fermenters from schist, marble, SS)
- Clay vessels for fermentation and ageing including fermentation on skins (DOC Vinho de Talha in Alentejo)
White wines:
- Pre fermentation skin contact (premium)
- Fermenting on skins
- Natural wines
Wine Law and Regulations in Portugal
PDO / PGI system:
- DOC / DOP: 31 DOCs (regional regulations, tastings)
- VR: regional wines, PGI, 14 VRs –> less stringent (more varieties)
- Vinho: all other wines
Grape Growing Environment in Vinho Verde DOC
NW Portugal
Climate: Moderate maritime
Influences:
- Atlantic –> cooling
- River Minho and Douro –> valleys funnel winds inland
- Peneda Geres National Park Mountains –> more continental in the east, poorer soils (subzones Baiao and Moncao e Melgaco) –> later ripening grape varieties (Avesso) and more body and alcohol (Alvarinho)
Rain: high at 1500mm throughout –> marked vintage variations
Soil: granite bedrock with shallow topsoil with sandy texture –> good drainage, low fertility –> fertilisers (manure) are needed
Vineyard Management in Vinho Verde DOC
Training: all high (for air circulation)
- trad: trained up trees or trellises over terraces –> air circulation
- now: single or double Guyot (replacement cane) with VSP or Lyre
Summer pruning: removal of lateral shoots, leaf removal, green harvesting –> better fruit ripening, air circulation
Grape Varieties in Vinho Verde
Shift from red to white (now 82 %)
Grape varieties:
- Loureiro: , white, coastal areas, early ripening, med plus acidity, citrus, pear, floral, herbal
- Alvarinho: white, Albarino, citrus, peach, some tropical, med plus body, med plus to high acidity, grown in the north, quality recognition –> increased planting
- Pederna: Arinto, white, mid ripening, more neutral, subtle citurs and apple, high acidity
- Avesso: white, late ripening, risk of unripe –> grown inland or south (fe Baiao) where warmer, lower acidity, full body, citrus, stone
- Trajadura (Treixadura): white, low acidity, apple, peach, often blended (for higher acidity)
- Vinhao: Sousao, Souson: black variety, deep colour, cherry, high acidity

Winemaking in Vinho Verde
Inexpensive:
- grapes from anywhere in the region and blended
- protective winemaking (cool ferm temp, SS)
- early bottling
- carbon dioxide added for light spritz
–> low alcohol, med plus to high acidity, apple, citrus and / or peach, sometimes RS
–> good, made my coops and merchants
Quality:
- small winemakers
- usually still, some single varietal, single sites
- some ambient yeast
- some old oak fermentation and / or maturation
- some lees ageing (few months) –> complexity, texture
- mid to premium
- VG

Grape Growing Environment in Duoro
Latitude: 41N
Climate: warm continental
Influences:
- Duoro River –> valleys, variety of aspects and altitudes –> huge range of microclimates
- Serra do Marao –> altitude, shields from Atlantic
Subregions:
- Douro Superior (Upper): hot and arid 450 mm
- **Cima Corgo **(Centre): warmer and dryer than Baixo 700mm rain
- Baixo Corgo (West): most Atlantic influences –> coolest and wettest 900 mm rain
Soil: schist bedrock, shallow soil –> stony, low water holding, but vertical layers –> deep roots to get water
–> irrigation allowed for quality
History and Business in Duoro
Grape Growing in Douro
Risks: spring frost at altitude, rain at flowering and fruit set in the west
Poor nutrients: fertiliser use, herbicides for weed control
Often hand harvest (steep slopes)
