Q

How and why are vintage ports declared?

A

How - producers register their intention to release a VP in the 2nd year after harvest. IVDP approve the young wine.

Why - grapes and young wines are of exceptional quality. Market conditions - if too close to a previous VP it may take sales away

Q

Describe businesses involved in Port production

A
  1. Land owners/growers - 20,000, average 2.2ha each. Most sell grapes to a medium or large producer or co-op
  2. Co-ops - produce around 20% of wine. Can sell under their own label but due to the prominence of the shippers brands they often sell wines to producers
  3. Shippers/Producers - 80% of sales by volume. 5 main groups
  4. Brokers - employed to facilitate trade of grapes and wine between growers/co-ops/producers
  5. IVDP - interprofessional body that governs and represents the interests of the producers of the region. Controls and supervises both fortified port and unfortified wine. Controls beneficio as well as amount of port sold each year. Approves wines for classification of age. Promotion of wine.

Q

Describe the soil type of the Duoro?

A

Stony shallow soils composed of schist.
This schist that defines the border of the Duoro.
Poor nutrients esp. nitrogen
Plate movements in the earth have caused the schist in the area to form vertical layers (usually horizontal) which enables roots to grow deep into soil to access water (this is unusual, as schist would usually develop horizontal layers).

Q

Similarities and differences of socalcos and patamares

A

Similarities: terraces, small tractors can be used (for the solcacos planted at lower densities), erosion (both on slopes, more of a problem for patamares)

differences: planting densities, labour, terrace wall, cost

Q

Advantages and disadvantages of the 3 vineyard layouts of the Duoro

A
  1. Solcalcos adv: terraces make an efficient use of space, make labour more accessible than sleep slopes, can be planted to high density (walls dont take up space)
    Solcalcos dis: high labour costs, expensive to maintain, can’t be changed (UNESCO)
  2. Patamares adv: lower construction and maintenance costs, some mechanisation, best for very steep parts
    Patamares dis: older versions have erosion, uneven ripeness on wide terraces
  3. Vinha ao alto adv: cheapest
    Dis: erosion, mechanisation impossible on very steep

Q

Describe the Beneficio system

A

Managed by IVDP.

Regulates the amount of Port must that can be produced in any one year.

Each vineyard is classified A to I (capacity to produce quality) based on location, aspect, altitude, soil, varieties.

A grade is the highest and can produce the most. Below F cannot make Port but unfortified wine or distilled into spirits.

Beneficio changes each year and is agreed upon between the growers, producers and IVDP and takes into consideration market demand and current stocks available in the market.

Aim: to keep grape and wine prices stable through its influence on the balance of supply and demand.

Vineyard owners granted beneficio card - which can be traded

19
Q

Who is the fifth largest Port Producer and its brands?

A

Sogevinus.

20
Q

How are vineyards classified in the Beneficio system?

A

Given a numerical score for each quality category: location, altitude, aspect, soil and grape varieties.

Final total of score is used to give a letter classification, ranging from A to I.

A denotes the highest quality and is therefore allowed to produce the most Port.

Vineyards below F cannot make Port, but unfortified wine or wine to be distilled into spirits.

21
Q

What is the aim of the Beneficio system?

A

To keep grape and wine prices stable through the influence on the balance of supply and demand.

22
Q

Trend of Port sales since 1970s

A

In growth from the 1970s until its peak in 2000. Declining ever since. Decline is mainly of inexpensive ports in France and Netherlands.

2020 - production 70 million litres vs sales 68m litres.

Average price however has increased due to increase in quality of production and the focus of marketing more premium ports such as age indicated Tawny.

23
Q

What are the IVDPs “special categories” and their proportion of volume and value of sales?

A

Reserve Ruby
Reserve Tawny
Reserve White
Age-indicated White
Age-indicated Tawny
Colheita
Vintage
Single Quinta
Crusted
LBV

23% of sales
45% of sales by value

24
Q

Climate of the Duoro Valley?

A

Warm, continental. Cooler and wetter in the west (Baixo Corgo), dryer (drought common) and warmer in the east (Duoro Superior)

25
Q

Soils of the Duoro Valley?

A

Stony, shallow which are free-draining.

Nutrient poor which limits vigour.

Composed of Schist which forms vertical layers, allowing roots to grow deep

26
Q

5 allowed varieties

A

Touriga Nacional
Touriga Franca
Tinta Roriz
Tinta Barroca
Tinta Cao

27
Q

List and describe the winemaking processes that take place for Port from arrival at the winery to start of maturation.

A
  1. Destemming optional.
  2. Fermentation and extraction of the black grapes with an option of methods; Shallow granite tanks (lagares) with foot stomping or modern lagares or autovinifiers, or also open stainless steel vessels with pistons. These extraction techniques work as effectively as possible.

Temp 28-32 (white port lower) for sufficient extraction. Modern lagares - SS so they can be temperature controlled, extend maceration.

Ambient yeasts.

3.. Drained from skins as quickly as possible

4.. Fortification - Fermentation is stopped to create a sweet wine after 2 days when wine is 5-7% abv with 80-120g/L sugar. Fortifying liquid is called aguardente, a 77% neutral grape spirit. Fortifies to 18-22% abv.

5.. Grape skins are pressed and this press wine will be blended into free run for colour and tannin required for wines set to undergo ageing

  1. Acidification is common as grapes are picked at flavour and tannin ripeness when acid has usually fallen. Malo is prevented by fortification.
  2. Clarification over winter in Duoro before being racked off lees, rotary vacuum filter used to extract remaining wine from lees.
  3. Blending can be done at any stage and is a key part of production - style and consistency.
  4. Spring - wines are moved to lodges in Vila Nova de Gaia for maturation.
28
Q

Where are Port wines matured and why?

A

Vila Nova de Gaia.

The climate is better suited to maturation - where the strong Atlantic influence keeps temperatures cooler and more constant.

29
Q

What is a Single Quinta Port?

A

In years when a producer does not make a Vintage Port, they may make a Single Quinta Port - wine from one year of grapes from one estate (Quinta) that is stated on the label.

30
Q

What is a Crusted Port?

A

NV Port aged in wood for maximum 2 yrs before bottling without fining or filtration - leaving a deposit (or crust) in bottle. ‘Bottled matured’ indicates 3 yrs ageing.

Similar in style to Vintage Port and ability to age. Good to very good.

31
Q

How long are Vintage Ports aged in wood and when are they bottled?

A

Maximum 3 yrs. Bottled in the second spring after harvest, i.e. 18-20 months in wood.

32
Q

Profitability of Vintage Ports.

A

Highly profitable as they are not aged for long periods in wood and are released early from the winery, destined for extensive bottle ageing. They garner high prices due to quality and agability.

33
Q

Describe the characteristics of a young Vintage Port and how it ages over time.

A

Young: pronounced intensity of ripe black fruits, sometimes floral notes, deep in colour, full-bodied, high tannins.

Ageing: flavours develop tertiary dried fruit and forest floor. Tannins and alcohol become better integrated. Very good to outstanding.

34
Q

What is a LBV Port?

A

From a single year and must be bottled 4-6 yrs after harvest.

Maturation in large old wood or SS vats that avoid oxidation.

Many are filtered, do not require decanting. Some are not and are more full bodied.

Not intended for bottle ageing but rather ready to drink on release.

Good to very good. More intensity, body and tannin and Ruby and Reserve Ruby.

‘Bottle matured’ - 3 yrs matured in bottle at winery unfiltered.

35
Q

What is ‘bottle matured’ appearing on a Port label.

A

In some Crusted and LBV Ports that have been aged in bottle before release for 3 yrs unfiltered.
