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 and what does it do?
A strong, hot and dry wind in late spring/early summer that lowers humidity/disease pressure, but can induce water stress/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 are Argentina’s three common soil types?
1) Andes - alluvial with calcarious deposits
2) Central - Gravel/sand/silt in centre
3) Lower lying - deep loam-clay higher in nutrients
What is the most common form of irrigation?
Flood
How and why is irrigation timing important?
More in winter and less in summer to replicate weather patterns and to ensure the roots grow and depth while preventing excessive vigour in favour of fruit development
What is the traditional training system and why?
1) Pergola
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 Bonarda in the vineyard (2)
1) Late ripening
2) High yielding
Where is Bonarda mainly planted? (2)
San Juan and warmer Mendoza
Why is careful site selection required for Cabernet Sauvignon in Argentina compared with Malbec?
It is more susceptible to extremes of temperature than Malbec
Where is Syrah mostly planted? (2)
Hotter Mendoza and San Juan
