Argentina Flashcards
(93 cards)
What helped Argentina’s wine industry through crisis times and how did it become one of the top producing and exporting countries?
- High domestic consumption
- Arrival of famous wine consultants
- Weak pesos
Climate
What is special about the location of vineyards in Argentina and what are the main climatic influences?
- Latitude: 24 to 38°S
- Altitude: 500 to 3,300m
- Combination of altitude and latitude is essential -> altitude moderates high temps at low latitude
- Most vineyards (except Patagonia) are located in the foothills of the Andes in the west of the country
- Still mostly flat or gently sloping sites
Climate
What are the effects of altitude on grape growing?
- Wide diurnal range
- Cooler night-time temps extend the growing season and help to retain acidity and aromas
- Intense sunlight and high proportion of ultraviolet radiation due to low latitude and high altitude
- -> grapes with higher tannins and anthocyanins
Climate
What is the general climate and rainfall? What does it mean for irrigation and diseases?
- Mostly continental climate
- Rain shadow of the Andes (sometimes < 200mm)
- Irrigation is essential
- Dry air and strong winds reduce risk of diseases
Climate
What are four viticultural hazards?
- Zonda wind: hot, dry powerful wind in late spring and early summer
- Effect: lowers humidity, can induce water stress, and can affect flowering and fruit set or damage grapes
- Mitigation: Trees to serve as windbreaks
- Hail:
- Effect: reduces yield significantly
- Mitigation: netting (expensive), different vineyard sites
- Frost
- El Niño: despite protection from the Andes
- Effect: much higher rainfall – and more hailstorms – which can damage crops, significantly increase the risk of disease
Soils
Describe the general soil type and the different textures with respect to their altitude
- Mostly alluvial soils
- Higher areas: larger stones with calcareous deposits (poor soils, optimal for naturally low yielding vines)
- Middle areas: gravel, sands and silts
- Lower areas: loamy-clay soils (more nutrients)
Soils
What type of soil is seen as a source of high quality wines and what are areas where it is found?
- Deposits of calcareous soils (poor)
- Gualtallary and Paraje Altamira in the Uco Valley
- Pedernal Valley in San Juan
Vineyard Management
What is the current area under vine and how was it 50 years ago? Why?
- 200,000 ha
- Considerably higher in 1970/80s
- Rapidly falling domestic demand
- Vine-pull scheme
Vineyard Management
What is the rainfall, where does the irrigation water come from?
- Rainfall is low
- Irrigation from rivers that deliver meltwater from winter snow and glaciers in the Andes
- Water is distributed regularly and can be stored in reservoirs until the wine producer chooses to use it
Vineyard Management
What irrigation methods are applied and how?
- Flood irrigation common (70% of vineyards)
- Recently more and more drip irrigation as it is cheaper and more sustainable
- Timing of water application: larger amounts in winter and low amounts in the growing season
- -> ensure roots grow deep
- -> vine focuses on fruit development rather than vigorous growth
Vineyard Management
What is the most common training system and why? What is increasingly used?
- High pergola system
- Raise grapes away from heat of the ground and provide shade for the fruit
- Esp. used for varieties in warmer areas that need shade (Torrontés) and/or have high vigor (Criolla Grande and Chica, Cereza and Pedro Giménez)
- VSP is increasingly used: allows for modern canopy management and drip irrigation
Vineyard Management
Comment on phylloxera and grafting
- Phylloxera not a major problem
- Grafting is increasingly used to get, e.g., tolerance to drought
Vineyard Management
How high is the risk of fungal diseases and what does it mean for organic and biodynamic viticulture? How is the adoption?
- Low risk of fungal disease -> little spraying needed
- Ideal for organic and biodynamic viticulture (adoption still low)
Vineyard Management
How is harvest typically conducted?
- Traditionally: harvested by hand by casual labourers
- Recently: more mechanical harvesting due to higher costs of living
Grape Varieties
What is the precentage of black varieties?
53%
Grape Varieties
What are the most planted grape varieties (in descending order)?
- Malbec
- Pink criolla varieties
- Bonarda
- Cabernet Sauvignon
- Syrah
- Pedro Giménez (white)
- Torrontés (white)
- Chardonnay (white)
Grape Varieties
What grapes did traditionally dominate plantings?
- High-yielding pink criolla varieties for inexpensive wines for domestic market
- Cereza
- Criolla Grande
- Criolla Chica (known as País in Chile)
Grape Varieties - Malbec
How much of vineyard area is planted to Malbec (%) and how is the trend?
- 20%
- Almost 5-fold increase in 20 years
Grape Varieties - Malbec
Describe the grape’s vigor and ripening time
- High vigor
- Mid-ripening
Grape Varieties - Malbec
What style of Malbec is hugely successful on the export market? (color, aromas, body, tannins, alcohol)
- Deep color
- Ripe blackberry and black plum
- Full body
- High but soft tannins
- High alcohol
Grape Varieties - Malbec
In what wines is the variety mostly used?
- Single varietal
- Blends (e.g., with Bordeaux varieties)
- Rosé
Grape Varieties - Malbec
Describe the style of Malbec from cooler sites (aromas, acidity, tannins, alcohol) and compare to one from a warmer site
- Cooler sites (e.g. high altitude or relatively high latitudes)
- Fresh red and black fruit and floral or herbal aromas
- Medium(+) acidity
- Firm, medium(+) tannins
- Lower alcohol
- Warmer sites (e.g. relatively low altitudes and latitudes)
- Riper fruit
- Lower acidity
- Fuller-bodied
- Softer tannins
Grape Varieties - Malbec
Describe the difference between Malbec clones used in Argentina vs. France
Argentina: smaller berries and bunches and softer tannins compared to France
Grape Varieties - Bonarda
What is the ripening time and where is it, hence, mostly planted?
- Late-ripening
- San Juan and warmer areas in Mendoza
