Madeira Flashcards
Ch 4 Madeira
Where is Madeira?
It is a Portuguese island in the Atlantic Ocean
It is ~600km from the coast of Morocco
What were the main exports of Madeira when the island was first discovered?
How and when did that change?
Initially sugar, wheat and (grape) vines were the main cash crops and exports
The sugar industry declined in the 16th Century (mainly due to competition) and wine became the main export
How did the style of Madeira come to be?
Exports of wine from Madeira grew in the 17th & 18th Century as British merchants arrived and sent wine to their colonies in N America & W Indies
It was found that long periods of time pitching and rolling in the holds of ships sailing to and from the tropics improved the quality of the wines – periods of time in variable temps and hot conditions
Soon, the wines were used as hold ballast (weight in the hull to balance the ship) on such trips with the sole purpose of improving the quality of the wine
What happened to Madeira in the 19th and 20th Centuries?
Mid to late 19th century = powdery mildew, then phylloxera, destroying vines and reducing yields
During the 20th century, Prohibition in the USA, 2 World Wars and the Russian Revolution negatively impacted the wine trade on many of Madeira’s major markets
Toward the end of the century sales became more stable, but tastes changed and sales fell well below their 18th century peak
What is the Instituto do Vinho da Madeira and when was it founded?
Founded 1979
Regulates production, although superseded in 2006 by the Instituto do Vinho, do Bordado e do Artesanato da Madeira, IP-RAM (IVBAM) [coordinates & supports Madeira and embroidery(!) industries]
What key factor led to an increase in the quality of Madeira wines?
Portugal’s entry to the EU in 1986, when more regulations were introduced
Additionally EU subsidies led to improvements in the quality of the wines
What is the climate of Madeira?
Warm summers (20-22C/ 68-72F)
Mild winters (16-17C/ 61-63F)
The majority of the rain falls in the autumn and winter
Warm and humid, with high disease pressure
How can Madeira’s climate be a problem?
It is so temperate that there can be a lack of winter dormancy in the warmest sites
Warm and humid with high disease pressure
How does the north and center of the Madeira island compare to the south?
The island has mountains reaching up to 1800m (vineyards up to 800m) which cause moist air in the humid winds arriving from the north to cool and condense into rainclouds, meaning that the north and center of the island are considerably cooler and wetter (rainfall can exceed 3000mm/yr in the center) than the south
What is the vineyard acreage of Madeira?
Where are the vineyards generally found?
Madeira has an area of ~74k ha of which only around 450ha are planted w/ vineyards
Vineyards can be found up to altitudes of around 800m and tend to be located relatively near the coast (forests mainly cover the center of the island)
Describe the soils of Madeira
Volcanic in origin and high in nutrients
What is the typical vine vigor in Madeira? Why?
High nutrient soils and plentiful rainfall provide fertile conditions for vigorous vines
How did the varieties planted in Madeira change with the arrival of powdery mildew and phylloxera?
Prior: Verdelho had been the most planted variety, with Malvasia and Terrantez being highly esteemed
After: American and hybrid varieties were planted to produce large, reliable crops (although these could not produce wines of the same quality)
After joining the EU, many of these (although not all) were replanted; note that the the remaining American and hybrids cannot be used for making Madeira
What was the traditional way of classifying grapes for Madeira? How is that now?
Traditional categories: noble, good, authorized
Now: recommended, and authorized, with the latter mainly made up of varieties that were introduced after phylloxera but without the same quality potential
What are the “noble” varieties of Madeira?
- Sercial, Verdelho, Boal, Malvasia
What is the main vinifera variety that has been planted in Madeira since the arrival of phylloxera? Why?
Tinta Negra
Produces high yields and is easy to grow
What are the varieties that are currently considered “recommended” in the production of Madeira?
- Sercial, Verdelho, Boal, Malvasia, Tinta Negra, Terrantez
Describe Tinta Negra (grape)
Black grape
Most planted variety on Maderia
High yielding and easy to grow
Used to make wines where a level of sweetness rather than grape variety appears on the label
Used in wines of all sweetness levels
Describe Sercial (grape)
Known for high acidity
Used in driest styles of Madeira
Late ripening and, especially in cool sites, is latest variety picked (barely above min potential alcohol levels)
Resistant to powdery mildew but susceptible to botrytis bunch rot
Can experience poor fruit set
Plantings are small
Describe Verdelho (grape)
2nd most planted vinifera variety on Maderia
High acidity but slightly lower than Sercial
Susceptible to botrytis bunch rot, coulure, and downy & powdery mildews
Describe Boal (grape)
Umbrella term for a # of grape varieties
The variety that grows in Madeira is Boal Cachudo, aka Malvasia Fina (as found in White Port)
Grows best on warm, low altitude sites in the S of the island
Susceptible to drought and needs adequate irrigation to survive
Typically used to produce semi-sweet wines
Describe Malvasia (grape)
This is an umbrella term for a # of grape varieties
Malvasia Candida was historically the most important Malvasia (in Madeira) and is still prized for its quality
Is susceptible to powdery mildew which can limit yields, therefore plantings are small
Malvasia de Sao Jorge is the most common grown on Madeira
Can produce high yields but is susceptible to botrytis bunch rot
Describe Terrantez (grape)
Plantings are limited
Susceptible to powdery mildew and botrytis bunch rot therefore it is picked soon after reaching 9% potential abv
Describe the vineyards of Madeira
Given the mountainous nature of the island, many vineyards are terraced to make planting on steep slopes viable
Vines are generally trained and trellised into a pergola system (here called latadas)
What are “latadas”?
Name for the pergola vine training system used in Madeira
What type of vine training is used in Madeira? Why?
Generally pergolas are used (here called latadas). Vineyards are also cordon-trained, VSP trellised (here called espaldeira)
Pergola allows air circulation above and beneath the vine which helps reduce incidence of fungal disease in the humid climate
It also permits other crops to be grown on the land underneath, making effective use of a small landholding
What is “espaldeira”?
Name used in Madeira for cordon-trained, VSP trellised vines
What are the key vineyard challenges in Madeira? Why?
Madeira has a warm, humid climate
This leads to challenges with downy mildew, botrytis bunch rot and Phomopsis
Are chemical treatments used in Madeira? Why/why not?
Madeira’s warm, humid climate leads to downy mildew, botrytis bunch rot, Phomopsis
While canopy management techniques can help, fungicide sprays are usually necessary
Is irrigation allowed in Madeira?
Yes, and it is widely practiced
Rainwater is carried from the center of the island to vineyard areas by “levadas” — small irrigation channels
With lower rainfall, irrigation is more required in the S of the island
When is harvest typically in Madeira?
Typically at end of Aug or start of Sept
Decided by IVBAM in consultation w/ producers and growers
How are grapes typically harvested in Madeira?
Given Madeira’s typography, it is not surprising that much is done by hand
What is the min potential alcohol at harvest for wines of Madeira?
9% abv, although generally picked at levels with avg potential alcohol of no more than 11% abv
What is the max yield in Madeira ?
Max yield varies according to vintage conditions
Yields as high as 150 hL/ha are not unusual (fertile soils, plentiful water)
What must happen to the grapes in Madeira upon arrival at the winery?
Grapes are checked for weight, health and potential alcohol (reps from IVBAM must be present)
Grapes are then destemmed and crushed
