2023 Argentina harvest
Smallest Argentinian harvest since 1960, down 23% from the year before
* devastating late spring frost
* hottest summer in a century
* irrigation water shortage
Most planted Argentinian grapes
1 Malbec
#2 Cereza
#3 Bonarda
#4 Cab Sauv
#5 Criolla Grande
Cereza is a crossing of?
Criolla Chica (Listan Prieto) x Moscatel de Alejandria
Listan Prieto - Argentina name
Criolla Chica
Bonarda - origins/synonyms
Douce Noire/Corbeau, once widely planted in Savoie
Torrontés - types, most planted, crossings
- Torrontés Riojano (moscatel x criolla chica)
- Torrontés Sanjuanino (moscatel x criolla chica)
- Torrontés Mendocino (moscatel x unknown)
*Riojano is the best and the most planted (with about 7650ha. Torrontés Sanjuanino is 2nd with 1620ha)
Argentina vine training + irrigation
- Modern: VSP with drip irrigation
- Old: parral (pergola) with flood irrigation
52% trained on pergola systems, especially Criolla grapes;
47% is VSP-trained (espaldera); 1%
is a mishmash of other training methods.
Main viticultural threats in Argentina (4)
- Esca
- frost, hail, Zonda
- nematodes
- mostly… lack of irrigation water
3 Argentina GI’s created on basis of geography, climate, etc
- Paraje Altamira GI (alluvial cone of Rio Tunuyan)
- Pampa El Cepillo GI (basically the plains below Paraje Altamira)
- Cordon El Cepillo GI (22; the ridge of the foothills)
-
San Pablo GI (climate - cool, humid & 20in/rain; proximity to Portillo Ridge)
Pampa El Cepillo GI
[Tapiz, Salentein, Zuccardi] - Los Chacayes GI: ‘17, geographical, not political (need to verify this)
[Lurton Bros]
Quebrada de Humahuaca GI
Jujuy (northernmost GI)
* Argentina’s highest vineyards.. up to 3329
* 42ha.. isn’t that important
Salta subregions
Cafayete
Molinos
Cachi
San Carlos
Salta’s subregions - most planted to least
- Cafayete - 2683ha
- San Carlos - 657m

Salta’s important river
Rio Salado
Molinos
Subregion of Salta; 130ha

Finca Altura Maxima
Colomé’s star vineyard in Molinos in the Salta. It sits at 3111M
Labels under the Valles Calchaquies GI
Diurnal Shift
- main factors
- Clouds: blanket effect. Block sunlight to moderate daytime temps, traps heat to moderate nighttime temps
- Humidity: water vapor in air absorbs heat. Humid places trapped warmth moderates day/nighttime temps
- Elevation: thinner air is less efficient at holding heat. Cools quickly at night
- Proximity to water: water heats/cools more slowly than land. smaller shifts
- Vegetation: plants/trees release moisture and impede rapid heat loss from ground at night
Frost factors
Cool climates: highest risk in spring with tender buds, young shoots
High diurnal shift areas: clear calm nights let heat radiate quickly from ground
Areas near water: water moderates day temps but doesn’t release enough heat at night to counterbalance rapid radiation cooling that leads to frost
Valley floors: cold air is denser; settles
Clear skies, lack of wind
UV ray + elevation relationship
- Methods to protect grapes
UV rays increase 4% per 100M. Grapes need more “sunscreen”
* N-S orientation to minimize sun
* train shoots vertically
* create a more diffused canopy with trellising system
* shade cloth
* Kaolin clay
Kaolin clay
natural mineral sunscreen for grape bunches
Cafayete - latitude, elevation, climate, grapes
26ºS; 1700 - 2000M
* Arid continental / 7.3in rain
* largest/southernmost Salta subregion
* poor rocky soils with high sand
* lots of old vines.. 1/3rd of vineyard is 100+
