29. Argentina Flashcards
Why does Argentina have a high rate of domestic consumption?
Generations of European immigration
What three general factors make Argentina suitable for grape growing
1) High altitude
2) Low latitude
3) Irrigation availability
What are the three pink criolla varieties important for domestic sales and consumption?
1) Cereza
2) Criolla Grande
3) Criolla Chica (Pais)
What is Argentina’s general climate?
Continental - hot and dry in Andean rain shadow
What are the two extreme north and south regions?
North - Salta
South - Rio Negro
What is the Zonda?
A strong, hot and dry wind in late spring/early summer
What is a positive impact of the Zonda?
Lowers humidity/disease pressure
What are two negative risks associated with the Zonda?
1) Can induce water stress by increasing evapotranspiration
2) Strength can affect fruit set and flowering
What are the three key weather threats, particularly in Mendoza
1) Hail
2) Spring frost
3) Summer rain
How is hail mitigated (2)
1) Netting
2) Owning plots across the region
What soils can be found in the higher altitude sites towards the Andean foothills?
Alluvial with larger stones and calcarious deposits
What combination of three soil types can be found in the central areas of Argentina?
Gravel/sand/silt
What soil can be found in the lower areas of Argentina?
Deep loam-clay higher in nutrients
What is the most common form of irrigation? Why?
1) Flood
2) It is relatively cheap to deploy for existing vineyards
Why is drip irrigation becoming more common for new vineyards?
It is cheaper and easier to install than levelling a sloped vineyard to enable flood irrigation
Why are Argentina’s soils particularly poor in terms of nutrients?
There is little organic matter due to the dry, continental climate particularly at higher altitudes
When is irrigation?
More in winter and less in summer
Why is the timing of irrigation important?
To replicate weather patterns and to ensure the roots grow at depth while preventing excessive vigour in favour of fruit development
What is the traditional training system and why?
1) Pergola (locally known as Parral)
2) Fruit is trained high away from ground heat and the canopy provides shade
What are the main four black varieties?
1) Malbec
2) Bonarda
3) Cabernet Sauvignon
4) Syrah
Describe Malbec in the vineyard (2)
1) Mid-ripening
2) Vigorous
Describe high altitude Malbec vs Malbec from warmer sites?
Higher acidity, lighter body, less ripe and firmer tannins
How might Malbec clones in Argentina differ from those in France? (2)
1) Smaller berries/bunches
2) Softer tannins
Describe Bonarda in the vineyard (2)
1) Late ripening
2) High yielding
What oak type (if any) is used for Bonarda and why?
1) Large and/or old
2) Oak can overwhelm the variety
In what two areas is Bonarda mainly planted? (2)
San Juan and warmer Mendoza
