Argentina Flashcards
How long is Argentina’s growing region for grapes?
Over 1,500km/870 miles
What are the two most important factors for growing grapes in Argentina?
The combined factors of Altitude and Latitude
How large is the diurnal shift in some regions of Argentina?
20°C/36°F
What is the climate of Argentina?
Continental
What mountain range causes the rain shadow that covers most of Argentina?
The Andes
What is one of the benefits of the rain shadow?
Disease pressure drops
What is one of the necessities for viticulture in Argentina due to the rain shadow?
Irrigation
Describe what the Zonda is
The Zonda is a fierce wind that comes down the Andes. It usually occurs during the late spring and early summer
Is the Zonda always a good thing?
No, it can cause water stress in the vine, and if it is strong enough, the Zonda can even affect flowering and fruit set.
What is a major concern for growers in Argentina during the summer months?
Hail, which has significantly affected yields in some years
What are some of the ways growers and producers can mitigate the threat of Hail?
- By using netting on their vineyards, with some only using the nets on their most prized sites
- Owning different parcels of land through out the region
What is another concern for growers/producers in Mendoza?
Frost, usually at the flatter areas or the bottom of the slopes
How can the El Niño phenomenon affect Argentina?
It can bring higher than average rainfall to the region, and with it more hail.
In 2016 there was a 25% drop across the country, and 40% in Mendoza due to El Niño
How often can the El Niño phenomenon occur?
Every two to ten years
What are the main soil type in Argentina
- Alluvial soils; however the textures of the soils will vary
What are some of the different textures/compositions of the alluvial soils found in Argentina
- Larger stones with calcareous deposits dominate the higher altitudes
- The middle areas are usually dominated by sand, gravel and silt
- The lower areas generally are loamy clay soils that are rich in nutrients
What regions have been identified with having deposits of calcareous soils, that some believe will become sources of high quality wines?
- Gualtallary and Paraje Altamira in the Uco Valley
- Pedernal Valley in San Juan
What triggered the vine pull scheme that was carried out in Argentina, and what was an unintended consequence of that vine pull scheme?
- It was triggered by the rapid fall in demand for domestic wines
- The unintended consequence was that thousands of acres of Malbec vines were ripped out before its potential was recognized
