Argentina Flashcards
Domestic consumption declined in Argentina in 1970s onwards. So what?
Along with return to democracy in 80s and 90s, producers (Eg Nicolas Catena) looked to export, and shift quantity to quality
Three significant wine consultants that impacted Argentina (modernisation)
Michel Rolland
Alberto Antonini
Paul Hobbs
Argentina has low latitude and high altitude. So what?
Vital, otherwise it would be too hot for viticulture
Altitude in Argentina
500m-3,300m
Topography of Argentina vineyards?
High altitude BUT
generally falt or gently sloping sites
Argentina has a high diurnal range (over 20C in some places). So what?
Cool nights extend growing season, allow grapes to retain acid and aromas
Combination of low latitude and high altitude means what for sunlight in Argentina?
Intense sunlight, relatively high ultraviolet radiation
=> high levels of tannins and anthocyanins
Climate in Argentina?
Mostly CONTINENTAL
Is rainfall high or low in Argentina?
Low!
Less than 200m in parts
Irrigation essential
What is zonda?
Hot, dry powerful wind in Argentina
Late spring, early summer
Lowers humidity, induce water stress, can affect flowering etc
How can growers mitigate against zonda in Argentina?
Use trees as a windbreak
What does hail do in Argentina?
a constant threat, can significantly reduce yields
How do growers mitigate against hail in Argentina?
Netting (but it’s expensive)
Spread vineyards around place (insurance)
What does El Nino bring to Argentina?
Every 2-10 years
Much higher rain than average, more hailstorms
2016: reduced production by 25% overall, 40% in Mendoza
Soils in Argentina are generally alluvial soils from what?
Deposited by rivers flowing down from the Andes
Poor soils at altitude in Argentina. Why? So what?
Dry continental climate so little organic matter from decomposed flora/fauna
Poor soils
Naturally low yielding, high quality viticulture
What’s notable about Gualtallary and Paraje Altamira (Uco Valley) and Pedernal Valley (San Juan)?
Deposits of calcareous soils found here
Increasingly known for high quality wines
Land under vine in Argentina
200,000ha (was much higher in 1970s/80s)
Vine pull scheme in Argentina in 80s/90s. So what?
area under vine went from 300,000ha to 200,000
response to rapid fall in demand
but 1000s of hectares of Malbec pulled out just before its potential was recognised!
Argentina: irrigation rainwater from where?
Rivers (eg the Mendoza and its tributaties) deliver pure meltwater from winter snow/glaciers in the Andes
Flood irrigation common in Argentina. Why?
Suitable for Argentina’s free draining soils
=> water goes deep in the soil
also: cheap!
used in 70% of vineyards
Drip irrigation is increasing in Argentina (vs flood irrigation which is most common). What are the benefits?
Increased efficiency
Little wastage
Sutstainable (water shortages an issue in Mendoza, La Rioja and San Jaun)
What is parral?
Argentinian pergola system, traditionally
Still widely used in warmer areas for eg Torrontés
Why is pergola/parral suitable for Torrontés?
it needs shade to retain acidity and aromas
