Q

Make the causal links between Argentina’s dry continental climate and high-quality viticulture at higher elevations.

A

a
Dry continental climate → little organic matter → poor soils, especially at higher elevations → poor soils are optimal for naturally low-yielding vines and high quality viticulture.

Q

Many vineyards in Argentina are irrigated using flood irrigation.

What is flood irrigation?

A

Both have calcareous soils.Water stored in reservoirs that’s released into vineyards through a network of dams and irrigation channels to flood the vineyard with the equivalent amount of water to a heavy rainstorm.

21
Q

Is Torrontés Riojano an early, mid-, or late ripening grape?
Is it vigorous/high-yielding, or is it non-vigorous/low-yielding?

A

a
Early ripening;
Vigorous/high-yielding.

22
Q

Because Torrontés Riojano is an early-ripening grape, what does this put it at risk of?

A

Becoming overripe in the heat → high alcohol, lacking acidity and structure, bitter finish.

23
Q

What is Argentina’s three-tier system of geographical indicators?

A

IP (Indicación de Provedencia): covers large geographical areas but not the country as a whole;
IG (or GI, Indicación Geográfica): wines of a certain quality made from a specific geographical area (most correspond to political divisions);
DOC: wines from a specific geographical area with legislated winemaking criteria – thus far only two: Luján de Cuyo and San Rafael, both in Mendoza.

24
Q

Argentina follows the 75% or 85% rule for stated vintage/variety?

A

85%

25
Q

In Argentina, a white or rosé Reserva wine must have aged a minimum of ___ months and a red Reserva for a minimum of ___ months.

Gran Reserva wines must be aged for a minimum of ___ months.

A

Reserva white/rosé – 6 months
Reserva red – 12 months
Gran Reserva – 24 months

26
Q

q
Mendoza accounts for ~___% of the total vineyard area in Argentina and ___ of total production.

A

70% of total vineyard area;
⅔ of total production.

27
Q

What are the five divisions of Mendoza’s growing area?

A

Northern
Eastern;
Central;
Uco Valley GI;
Southern.

28
Q

Northern and Eastern Mendoza produce what style of wine? Why?

Which rivers irrigate each area?

A

Style: large volumes of inexpensive wine due to lower elevation;
Northern irrigated by Mendoza River;
Eastern irrigated by Tunuyán River.

29
Q

q
Central Mendoza

What is the elevation range?
What are the two prestigious wine departments?

A

600 – 1100m asl;
Luján de Cuyo + Maipú.

30
Q

What is the elevation range for Maipú?
What is the elevation range for Luján de Cuyo?

A

Maipú: 600 – 900m asl;
Luján de Cuyo: 900 – 1100m asl.

31
Q

What is the aging regulation in DOC Luján de Cuyo?

A

Wines must be aged for a minimum of 24 months with at least 12 months in oak.

32
Q

Why are Luján de Cuyo wines considered to have more aging potential than Maipú wines?

A

High tannins (due to elevation, poorer soil, higher solar interception, higher diurnal range).

33
Q

What is the elevation range for Uco Valley?

A

a
850 – 1500m asl (highest vineyards in Mendoza).

34
Q

Why has there been such enormous investment in Uco Valley?

A

The potential to make great wines:

High altitude (cooler temps, greater diurnal range);
Grapes will accumulate sugar less quickly, retain acidity and fresh fruit flavors;
Intense sun will give grapes deep color + ripe tannins.

35
Q

What is the most recognized district of Tupungato?

Describe it and its soils.

A

a
Gualtallary

It’s a long narrow strip of vineyards between 1,100 – 1,600m asl producing wines of freshness/acidity due to diurnal shift;
Limestone soils.

36
Q

Which white grape variety is San Rafael known for?

A

Chenin Blanc.

37
Q

With San Rafael at a lower elevation, one would think its Malbecs would be full throttle and heavily extracted – but they’re not.

What factors make their Malbecs medium bodied and red-fruited?

A

San Rafael is more south, or further away from the Equator, which means its summers are cooler and longer than in regions more north;
It also does not have the same solar intensity as regions further north.

38
Q

Why has San Juan province been known for inexpensive, high-yielding pink varieties?
How is that changing?

A

Its sites are lower than Mendoza’s → less diurnal range;
Replanting with Syrah at higher elevations to make fresher, higher acid wines.

39
Q

What is the GI in San Juan province that’s making a mark with its Syrah?

What is its elevation?

A

Pedernal Valley (1250 – 1500m asl)

40
Q

q
What style of wine is La Rioja Argentina province known for?

What is the name of the Valley where most of these grapes are grown?

A

Inexpensive, high-volume red and white wines from Famatina Valley.

41
Q

What is the river that provides irrigation for Salta province?

A

Calchaquí River.

42
Q

What is the elevation range for Salta’s vineyards?

A

1500 – 3000m asl (this extreme elevation offsets the proximity to the Equator).

43
Q

How do the zonda, high elevation and low latitude lead to higher tannins and deeper color in red wines from Salta?

A

The zonda dries out the environment while the low latitude and high elevation mean intense sunlight leading to grapes with higher levels of tannins and anthocyanins. The grapes also protect themselves from the strong zonda resulting in thicker skins and lower yields – plus, the large diurnal shift is large, so grapes produce very concentrated, intense, and full-bodied wines.

44
Q

Which GI in Salta is known for its Torrontés?

A

Cafayate.

45
Q

q
Patagonia Region

What is its altitude?
What is its latitude?

A

~400m asl;
38° - 39°S.

46
Q

q
Patagonia Region:

What are its temperature and sunlight like?
What is its rainfall like, and do they have to irrigate?

A

Lower temps, sunlight less intense;
Low rainfall (<200mm/year), so irrigation is essential.

47
Q

Winds in Patagonia keep fungal disease at bay but can be damaging and disrupt flowering.

How do grape growers protect their vineyards from these winds?

A

They grow poplar trees as barriers.

48
Q

What are the two provinces in Patagonia?

A

Río Negro;
Neuquén.

49
Q

FeCoViTa and Grupo Peñaflor are amongst the world’s _____ producers.

a. lowest-volume
b. highest-volume
