Ch. 28 – Chile Flashcards
Geography and climate in Chile
Atacama Desert to the north
Fairly consistent climate from north to south.
- warm Mediterranean
- long dry summers (cooler and wetter further south)
- Low latitude = strong sunshine
El Nino phenomenon (high rainfall)
La Nina (drought)
- significant vintage variation
Pacific and Andes are cooling influences
- lengthen growing season
- acidity retention
Humboldt current (from Antarctica)
- brings cold water and cool air
- cool air sucked inland, creating fog
- increased humidity
- coastal ranges (low mountains) protect inland valley
- gaps in coastal ranges allow cooling influence to extend inland
Planting on hills can also provide cooling influence from altitude
Cool air descending from Andes
- high diurnal range
Soils in Chile
Fertile river valleys (alluvial soils with clay, sand, silt and gravel)
Slopes are less fertile
- Coastal ranges have more gravel with sand and silt
- Andes has volcanic soil, mainly granite
Very limited limestone in Chile (some in Limari)
Vineyard management in Chile
Reliable ripening
- intense sunshine = high tannins/anthocyanins
Risk of fungal diseases usually minimal
- can be an issue in foggy coastal regions
- sustainable and organic is widely practiced
85% of vineyards are irrigated
- except Itata, Bio Bio
- rivers bring water from melting snow
Forest fires + smoke taint
Phylloxera free
- old ungrafted vines
- new vines often grated to prevent nematodes
VSP is now common
- Mechanization is easy on flat land
- Machine-harvesting still uncommon, due to cheap labour
Grape varieties in Chile
and winemaking
Until 1990 most common was Pais
- 75% was pulled up since 1980
Recent shift towards international varieties, i.e. Bordeaux
A leading supplier of fruity inexpensive wines
Increasing diversity of wine styles
- experimenting with new varieties like Viognier, Riesling, Gewurtz
Experimentation with less oak, concrete, whole bunches, gentler extraction, skin and lees contact
Key black grape varieties in Chile
Cabernet Sauvignon
- single varietal or blend with Merlot, Carmenere, Syrah
- Full body, high but ripe tannins, pronounced dark fruit
- Often herbaceous (mint, eucalyptus) character
- best sites in poorer soils of Andes
Merlot
- Usually inexpensive, exported
- soft tannins, med body, dark fruit
Carmenere
- officially identified in 1994 (confused with Merlot)
- full body, high tannin, med acidity, black fruit, herbaceous, spice
- Site selection is important
- Ripens 3 weeks later than Merlot (needs warmth and sun)
- Can get overly alcoholic
Syrah
- cooler-climate peppery style to warmer-climate style in Colchagua Valley
Pinot Noir
- improving rapidly
Key white grape varieties in Chile
Sauvignon Blanc
- cooler areas
- very good quality, high acidity, citrus to tropical
- often herbaceous
- sometimes lees contact and oak
Chardonnay
- med+ (high) acidity
- citrus, stone fruit
- oaked or unoaked
Official wine law (DOs) in Chile
1995 Decominaciones de Origen (DOs)
6 main regional DOs (mainly along political boundaries)
- e.g. Central Valley
Sub-regions (following river valleys)
- e.g. Rapel Valley
Zones within sub-regions
- e.g. Colchagua
Areas (can belong to zone or sub-region, if zone does not exist)
- e.g. Apalta
Addition to DO system in Chile
‘East to west classification’
2011 addition to DO system
Costa (coastal influence)
Entre Cordilleras (between)
Andes
(slow to adopt this system)
DO requirements in Chile
75% of grapes must come from the region
(or 85% if exported to Europe)
Varietal labelling
- 75% from that variety
- or 85% if exported to Europe
Minimum alcohol 11.5%
Legally recognised labelling terms in Chile
Reserva (min 12%)
Reserva Especial (min 12%)
Reserva Privada (min 12.5%, min 6 mths in oak)
Gran Reserva (min 12.5%, min 6 mths in oak)
Some producers use these to distinguish between wines in their portfolio
