21 - Portugal Part 1 Flashcards
Describe the growing conditions throughout Portugal with reference to different regions.
Climate
- Maritime (Vinho Verde) with more continental climates inland (Douro)
- Rainfall varies based on prox to coast e.g:
- Baixo Corgo → 900mm
- Douro Superieur → 450mm
- S regions warmer + drier e.g.
- Tejo →Mediterranean
Topography
- Mountain ranges limit maritime influence inland
- S → flatter
Soils
- Schist + granite→ mountainous regions
- VV, Douro
- Dao
- some Alentejo
- Varied soils in S, clay + limestone + sand
- Alluvial → Tejo
What has happened to the area under vine in Portugal? (3)
Reduced by 30%
→ mainly high y. vineyards in Tejo and VV
Some replanting with HQ vines but limited to avoid surpluses
Alentejo has increased
→ warm, sunny + flat
→ ideal for ripe, soft style for domestic and export markets
+ lots of money for investment esp. in large estates
Outline the main viticultural hazards experience in Portugal (6)
- Drought esp. Inland + S (Douro, Dão, Alentejo)
- Hail + storms
- Wildfires
- Untimely rain → VV
- Trunk disease
- Grapevine moths
While most vineyards are cordon/RCP with VSP, there is a significant number of bush vines found where? How are these used to make wine?
Old bush vines in Douro and Alentejo → often co-planted + picked as field blends
To what extent is irrigation permitted?
enable ripening, not to boost y.
must notify (IVDP) if
To what extent is organic viticulture practised?
Widely practised but only a few certified due to cost
Warm, dry climate esp. Inland
To what extent are native and int’l varieties planted in Portugal? How has this changed?
Of top 12 planted varieties, 11 are native
int’l varities more popular in S → movement back to natives esp. from small, quality focused producers
How has EU-related investment improved winemaking in Portugal?
Are there any traditional winemaking techniques that are still used?
Are there any new wave practices being adopted?
Modern innovation
- Destemming machines →improved tannin mngt
- French oak barrels for mat → improved tannin mngt
Traditional techniques
- Use of large Portugese oak → still popular in Bairrada
- Foot treading using Lagares
New wave
- Amphora
- Pre-ferment and ferm skin contact → prem white
- Natural wine
Briefly outline the PDO/PGI system in Portugal.
DOC/DOP → (PDO) - 31
VR → (PGI) 14, allowing int’l varieties and less strict
Vinho → (NO GI)
How does the climate(s) of Vinho Verde influence viticulture and the style of wine produced?
1500mm rainfall → rot + mildew
- Modern → RCP with VSP or lyre
- → trained high for circulation
- summer pruning to thin canopy
- some → traditional tree training
- Significant VV
- Mainly white
- Mid-rip Loureiro most widely planted → mid-ripening → avoids worst rains
- Early picking resulting in low ABV
- Warmer, drier in Baião → late ripening varieties e.g. Avesso → full body with citrus and stone fruit
-
Poor soils
- → grantic bedrock with thintopsoil
- → well drained + poor in nutrients
- → supports large training system like Lyre
- → prevents overly vegetative growth
Describe how summer pruning is performed (3).
- Remove lateral shoots → non-fruit bearing
- Remove leafs → can be done mechanically
- Green harvesting → removing bunches before veraison to mod y.
Name and briefly describe the 5 main grapes that go into white Vinho Verde.
1. Loureiro
- mid-ripening
- med(+) acid
- citrus, pear, floral, herbal
2. Alvarinho
- high q.
- growing plantings
- highish acid
- citrus, peach, tropical
3. Pederna (Arinto)
- mid-ripening
- neutral
4. Avesso
- late-ripening
- lower in acid/fuller in body
- citrus and stone fruit
5. Trajadura
- low acid
- apple and peach
Describe the winemaking for white Vinho Verde and the style of wine produced.
- Major inexp, high-vol → blend of grapes across region
- Protective with cool ferm in SST, bottled soon after, CO2 may be added for spritz.
- Some RS may be retained for balance
- Apple, citrus, peach, Min of 8% ABV, highish acid
Describe how winemaking and regulations differ for higher quality Vinho Verde (4).
- labelled with sub region
- single variety esp. Alvarinho
- Min 11.5% ABV
- ambient yeast
- old oak ferm
- lees ageing
Describe red Vinho Verde.
14% of production
- made from Vinhão → deep colour with cherries + high acid
