D5.C4. Madeira Flashcards
The Island of Madeira began to be colonised by Portuguese shortly after which year
1420
How did the grape become the main export during 16th century?
Although initially sugar, wheat and vines were the main crops and exports, the sugar industry declined during the 16th Century mainly due to competition from other countries, and wine became the main export
How is “Madeirasation” invented?
It was found that long periods of time in variable temperatures and hot conditions in the holds of ships sailing to and from the tropics improved the quality of the wines and soon the wines were used as hold ballast on such trips, with the sole purpose of improving the quality of the wine
Which events adversely affected Madeira wine trade in 19th and 20th centuries?
- 19th century: Powdery mildew and then phylloxera
- 20th century:
+Prohibition in the USA
+World Wars
+Russian revolution
In which century, the sales for Madeira peaked?
18th century
What are the institutes founded to supervise Madeira production?
- The Instituto do Vinho da Madeira in 1979
- It is uperceded in 2006 by the Instituto do Vinho, do Bordado e do Artesanato da Madeira (IVBAM)
How is the climate in Madeira?
- Warm summers (around 20–22°C)
- Mild winters (around 16–17°C)
What can be the adverse result of mild winters in Madeira?
Lack of winter dormancy can be a problem in the warmest sites
What is the effect of high mountains reaching up to 1800 m, on the climate of Madeira?
They cause moist air in the humid winds arriving from the north-west to cool and condense into rainclouds, meaning that the north and centre of the island are considerably cooler and wetter
What is amount of rainfall in Madeira?
- It can exceed 3,000 mm
- The majority of rain falls in the autumn and winter
What is the total area under vine in Madeira?
450 ha
Vineyards are located in which areas of Madeira?
The vineyards can be found up to altitudes of around 800 m and tend to be located relatively near the coast with forests covering the mountainous centre of the island
How is the soil in Madeira?
Volcanic and high in nutrients
How is the vigor of the vines in Madeira?
The fertile soil together with the plentiful rain result in vigorous vines
How did the powdery mildew and phylloxera dramatically changed the make-up of grape varieties on Madeira?
- Producers began to plant American and hybrid vines that were more resistant to pests and disease, and could therefore produce large, reliable crops
- However, these vines could not produce wines of the same quality as vinifera varieties
- With help from EU schemes, a significant proportion of these vineyards has been replanted
What is the traditional and contemporary classifications for the grapes used for Madeira?
- Traditional: Noble, good and authorized
- Contemporary: Recommended and authorized
What are the noble grapes for Madeira?
Sercial, Verdelho, Boal and Malvasia
What is the main vinifera variety that has been planted after phylloxera?
Tinta Negra (once categorised as ‘good’ but now is ‘recommended’)
What are the properties of Tinta Negra?
- Most planted variety on the island
- High yielding and easy to grow
- Only since 2015, that producers have been able to state the grape variety, Tinta Negra, on the label
- Much Tinta Negra is used to make wines where a level of sweetness rather than a grape variety appears on the label
- Used to produce wines at all sweetness levels
What are the properties of Sercial?
- High acidity
- Used in the driest styles of Madeira
- Late ripening and especially in cool sites can be the latest variety to be picked
- Resistant to powdery mildew
- Susceptible to botrytis bunch rot
- Can experience poor fruit set
- Plantings are small
What are the properties of Verdelho?
- It is the second most planted vinifera variety
- High acidity, slightly lower than sercial
- Susceptible to botrytis bunch rot, coulure, and downy and powdery mildews
What are the properties of Boal?
- It is an umbrella term for a number of grape varieties
- The variety that grows on Madeira is Boal Cachudo, and is also named Malvasia Fina
- It grows best on the warm, low altitude sites in the south of the island
- It is susceptible to drought and therefore needs adequate irrigation to thrive
- Typically used to produce semi-sweet wines
What are the properties of Malvasia?
- It is an umbrella term for a number of grape varieties
- Malvasia Cândida was historically the most important Malvasia, and is still highly prized for its quality but it is very susceptible to powdery mildew, so plantings are limited
- Malvasia de São Jorge is the most common Malvasia grown on Madeira. It can produce relatively high yields but is susceptible to botrytis bunch rot
What are the properties of Terrantez?
- Plantings are very limited
- It is susceptible to powdery mildew and botrytis bunch rot and is therefore picked soon after it reaches 9% abv potential alcohol
What is the layout of the vineyards in Madeira?
Since Madeira is a mountainous island many vineyards are terraced to make planting on steep slopes viable
What is the common training systems in Madeira?
- Vines are generally trained and trellised into a pergola system, here called latadas
- Vines are also planted with cordon-trained, VSP-trellised vines, here called espaldeira
What are the advantages of pergola system (latadas) in Madeira?
- It allows air circulation above and beneath the vine which helps reduce incidence of fungal disease
- It also permits other crops to be grown on the land underneath, making effective use of a small landholding
Why is the disease pressure high in Madeira?
Because of Madeira’s warm, humid climate
Which diseases are common in Madeira?
- Downy mildew
- Botrytis bunch rot
- Phomopsis
How do the growers fight against diseases in Madeira?
- Canopy management: Shoot positioning and leaf removal
- Fungicides
Is irrigation required in Madeira?
With lower rainfall, irrigation is more required in the south of the island
Where does the water for irrigation come from in Madeira?
Rainwater is carried from the centre of the island to vineyard areas by small irrigation channels called “levadas”
How is the harvest date decided in Madeira?
The official harvest date is decided by IVBAM in consultation with producers and growers
When is the usual harvest date?
Usually at the end of August or the start of September
What is the common method for harvesting?
Hand harvesting due to the topography
What should be the minimum potential alcohol at harvest in Madeira?
9% abv
In general, when are the grapes harvested in Madeira in terms of potential alcohol?
They are picked with average potential
alcohols of no more than 11% abv
Which factors affect the price of the grapes in Madeira?
- Grape health
- Grape variety: Traditional varieties of Sercial, Verdelho, Boal, Malvasia and Terrantez fetch much more than Tinta Negra
What is the maximum permitted yield in Madeira?
The maximum permitted yield varies according to the vintage conditions, but high yields of 150 hL/ha are not unusual
What is the first action when the grapes arrive in the winery in Madeira?
The grapes are checked for weight, health and potential alcohol, destemmed and crushed. Representatives of IVBAM must be present for the arrival of all grapes!
Is skin contact used in the production of Madeira?
- It varies according to the producer
- Wines from Tinta Negra are often fermented on their skins, particularly for medium sweet and sweet styles of wine
What is the preferred vessel for the fermentation of Madeira?
