Q

Explain the soil structure of the Douro

A

Stony, shallow soils

Free-draining and poor in nutrients which limits vigor

Underlaying bedrock is made of schist, rocks that crumble into layers quite easily. Due to these layers roots are able to penetrate deep into the soil to find water

Q

Name the two types of Patamares

A

Large Patamares, are wide Patamares that support two rows of wines on each terrace. Uneven ripeness can be an issue, with the exterior row vines gaining more sun exposure.

Narrow Patamares only support one row of vines. Uneven ripening is less of a problem. More modern these days

The least expensive and allows relatively high density plantings (5000 ha)

Above 40% incline mechanization cannot be used, in that case Patamares are more likely

Water runs of and erosion can be a problem

Use of this vineyard layout is currently relatively limited

Q

Hazards in the Douro

A

Spring frost in high altitude vineyards

Cool wet weather from the east during early summer disrupts flowering and fruitset

Downy mildew and botrytis bunch rot can be an issue (especially in Baixo Corgo, wettest region). Which can be combatted by canopy management and spraying with fungicides

Q

Harvesting

A

Mainly carried out by hand because most of the vineyards are not suitable for machine harvesting

Usually starts in the Douro Superior (warm) and ends in the Baixo Corgo (cooler).

The various micro climates, different grape varieties and the time consuming job of hand harvesting, means that harvest is spread out over several weeks

Q

Touringa Franca

A

Late ripening, suitable for growing in warmer sites (low altitude, south facing)

Tight bunches and thick skinned grapes, relatively resistant to fungal diseases

Contributes colour, tannin and acidity as well as juicy black and red fruits and floral aromas

By far the most grown variety

32
Q

Tinta Roriz

A

Tempranillo in Spain and Aragonez elsewhere in Portugal

Early ripening, best grown in relatively cool sites and can suffer from water stress

Can give body and deep colour to the blend

Capable of producing high yield, but needs to be limited otherwise wines will lack concentration

33
Q

Tinta Barroca

A

Early ripening variety, best planted in cool sites (Baixo Corgo and Cima Corgo) on high altitude north facing slopes

Flavors tend to be more earthy than floral

It can lack acidity and colour tends to fade more quickly

Capable of producing high yieldsq

34
Q

Touriga Nacional

A

Mid ripening, thick skinned

Producing wines with deep colour and high tannins

Retains acidity well and displays concentrated flavors of black fruit and flowers

Long ageing potential and therefor often used in premium, long matured wines

Can suffer from excessive vegetive growth, which can be managed by summer pruning

Susceptible to coulure, which can lower yield and quality

35
Q

Tinta Amarala

A

Trincadeira in other parts of Portugal

Prone to fungal diseases due to its tight bunches of grapes

Gives full body wines, concentrated black fruits with spicy notes

Approachable in yought but capable of ageing

36
Q

Tinta Cao

A

Low yielding variety

Small thick skinned, resistant to fungal disease

Ripens late and very tolerant to heat

Concentrated wines, high acidity and capacity to age well

37
Q

Sousao

A

Thick skinned variety

Becoming increasingly popular for its deep intensity of colour and ability to retain high levels of acidity

38
Q

Key white varieties in Port production

A

Malvasia Fina and Moscatel Galego Branco

39
Q

Malvasia Fina

A

Boal in Madeira

Produces neutral wines with medium acidity, full body and slightly honeyed character

40
Q

Moscatel Galego Branco

A

Muscat Blanc a Petit Grains

An aromatic grape variety used for un aged styles

41
Q

Key methods of extraction during fermentation

A 
Foot trading in lagares
Modern lagares
Pumping over
Stainless steel pistons
Autovinifiers

Fermentation is stopped by the addition of grape spirit to create a sweet wine (80-120 g/l) residual sugar. Maceration of the skins last for a max of 2 days and therefor extraction techniques need to be very effective

42
Q

Foot trading

A

Takes place in shallow (80cm) square tanks, traditionally made of granite

The extractions comes from foot treading, effective but also gentle enough not to crush the seeds (bitter tannins)

Still used by a number of small, premium and super-premium producers

43
Q

Modern lagares

A

Also called robotic lagares, silicon feet press the grapes against the lager floor and punch down the cap

Advantage is that it reduce the need for a large hired workforce

However the initial investment is for the equipment is higher, modern lagers can produce wines of equal quality to those produced by foot treading

44
Q

Pumping over

A

Same technique used for non-fortified wines

Although it can produce ports with deep colour and high levels of concentration through frequent pumping over, it is not as effective as foot treading or the use of modern lagares

45
Q

Stainless steel pistons

A

Open stainless steel vats with pistons punching down the cap to a programmed schedule.

Can be used in conjunction with pumping over, which is usually needed to promote more even extraction

Believed to be almost as effective at extracting as lagares and seems to produce wines that are similar in quality

46
Q

Autovinifiers

A

Sealed concrete stainless steel tanks proved a solution to cap management that does not require electricity

The rising pressure of the co2 produced from fermentation pushes the juice up through the pipes into a holding tank

When the pressure of the co2 reaches a certain level, a valve (klep) is automatically released and the wine in the holding tank sprays over the cap

Cheaper option, because it does nog require electricity

Very little extraction occurs before fermentation starts, because the process is reliant on co2 released from fermentation. Therefor more suitable to produce basic tawny, ruby and white Ports

47
Q

Fermentation temperatures for Port wines

A

Red wines 28-32 degrees is warm enough to allow sufficient extraction but not so warm that the fermentation progresses too quickly and reduces the available extraction time before pressing and fortification

Fermentation temperatures for whites are around 20 degrees or below

Many producers use ambient yeasts for fermentation as these are sufficient to start the ferment (completing fermentation to dryness is not a concern for Port production)

48
Q

To what level of alcohol is Port foritified

A

19-22%

49
Q

Explain aguardente

A

Spirit derived from grapes with a min of 77% abv

The alcoholic strength of aguradente is relatively low compared to 95-96% aft spirits used in otters fortified wines. Whereas 95-96% spirit is neutral 77% abv spirits have more character, and is the reason Port displays more spirity aromas

Approx 1l of spirit for every 4l of fermenting must is used to produce a fortified wine of 20% abv. No surprise that the quality of the spirit has a significant influence on the style and quality of the wine

50
Q

Explain the influence on style of aguardente

A

Approx 1l of spirit for every 4l of fermenting must is used to produce a fortified wine of 20% abv. No surprise that the quality of the spirit has a significant influence on the style and quality of the wine

Some producers will use a relatively neutral spirit to best show the character of the wine, others may use spirits that are more aromatic to add a certain character to the wine

The spirit chose will also effect the price of the final wine, therefor high quality spirits will be added to premium wines, whereas less expensive spirits will be added to inexpensive wines

51
Q

Port fortification

A

Fermentation is stopped when the wine reaches around 5-7% abv, depending on the desired sugar level to remain. Generally 80-12 g/l, which can be a matter of house style

The wine is drained from the skins before the aguardente is added. Meaning this must be as efficient as possible, as the must will continue fermenting (until the aguardente is added) using up sugar that may be desired in the final wine

Modern fermentation vessels are generally designed to drain as quickly as possible, compared to traditional granite lagares which can take hours to drain

The mass of grapes skins left after drainage will be pressed and blended into the fortified free run wine. To provide colour and tannins (necessary for wines that undergo long term ageing)

52
Q

Acidification

A

Grapes are picked when flavors and tannins are ripe, too much potential alcohol is not an issue, but acidity can be lowered. Therefor acidification is common

53
Q

Malolactic fermentation

A

Ports do not go though malolactic fermentation, as lactic acid bacteria are unable to tolerate the high concentration of alcohol

54
Q

Explain blending in Port wines

A

Port are generally blends of different vineyards, grapes, and depending on the style vintages

Many Ports are non-vintage products with consumers expecting consistency (house style) and hence blending is used to ensure this

Blending is also important for producing a wine of the right profile and quality for the style it is to become. Vintage Port will have deeper colour and greater concentration of flavor and higher tannins compared to a Reserve Ruby or LBV. All of these factors mean that the more stock a shipper holds, the easier it is to create a range of different styles

55
Q

Maturation

A

The climate of Vila Nova de Gaia is better suited for Port ageing than the wineries in the vineyards, with strong Atlantic influences the temperatures are generally cooler and more constant. However, its becoming very touristy and more producers have built humidity controlled lodges in the vineyard area

Most styles are aged in oak. Vessels vary considerably in size depending of the amount of oxidation desired. The largest, called balseiros, are vats that can hold 100.000 liters, if gentle oxidation is desired wines are usually aged in 600 liters barrels called pipes.

The aromas of new oak are not wanted

56
Q

Basic Ruby

A

Medium bodied, with medium tannins with red and black fruit flavours and suitable for drinking early, not for ageing.

Usually produced using protective winemaking techniques to retain primary fruit flavours. Including fermenting in stainless steel or concrete and ageing te wines in bulk for a max of 3 years

Generally a blend of more than one year and is expected to have the same consistent taste year on year.

Generally acceptable to good quality and inexpensive to mid-priced. Due to limited ageing and cheap spirit the wines often have simple fruity flavours and can have slightly harsh alcohol

57
Q

Basic Tawny

A

May show some lightness and browning of colour in common with other Tawny Ports, but this does not tend to come from long periods of oxidative ageing.

Often aged no longer than Ruby Ports. Rather made by light extraction during fermentation to give them a paler colour

58
Q

Reserve Tawny

A

Higher in quality than basic Tawny’s and must be aged in wood for a min of 7 years

59
Q

Reserve Ruby

A

They tend to be higher in quality and more concentrated than basic Ruby’s

There is no min of ageing period. However, they must be tasted and approved by the IVDP’s tasting panel.

60
Q

Tawny with an indication of age

A

Aged for a long time in barrels, typically pipes holding 620-640 liters. Permitting a controlled exposure to oxygen and over time tannins soften, alcohol becomes more integrated and primary flavours develop into tertiary flavours (dried fruit) and caramel and nuts from oxidation

Due to the long ageing, clarification and stabilization occurs naturally and wines tend not to need filtration before bottling

10,20,30 or 40 years can be stated on the lable, blends of more than one vintage made up of wines that are younger and older than the age specified. The wines will be tasted by a panel within the IVDP and must have the character of a wine of that age

Within their long ageing, barrels need racking and topping up (due to evaporation) making the production relatively expensive

61
Q

Old aged Tawny

A

Started with the launch of Taylor’s Scion, a Tawny Port of more than 150 years old. Some other shippers have launched there own versions

Given their rarity and long maturation this wines sell at super premium prices

62
Q

Colheita

A

Tawny Ports made from grapes from one vintage are called Colheita Ports

Must be aged in small barrels for a min of 7 years. The label must state the vintage and the year the wine was bottled

63
Q

Vintage Port

A

Wines from a declared vintage. Producers must register their intention to release a Vintage Port in the second year after harvest and the wine is approved by an IVDP tasting panel

As well as a very good vintage, the grapes will come from high quality plots, usually own vineyards and old vines (Quinta do Noval Nacional). Touriga Franca and Touriga Nacional are usually key components in the blend giving colour, tannin and flavour concentration suitable for long term ageing. These wines will be tasted over the period of the next two years to determine if a vintage can be declared and which lots may be suitable for Vintage Port. Wines that do not become Vintage Port after this period may become Single Quinta Ports, LBV or Crusted Port

Vintage Ports undergo a max of 3 years in large old wooden vessels before extensive bottle ageing. The majority is bottled during the second spring after harvest (18-20 months). The small amount of oxygen exposure during this times ensures stability of colour over its long ageing.

Wines are bottled without fining or filtration, results in heavy deposit of segment on opening and pouring

Young Vintage Ports are deep in colour and full bodied with high levels of tannins and pronounced intensity of black fruit. As they age the develop flavours of dried fruit and tannins and alcohol integrate. Very good to outstanding in quality, and sell for premium to super premium prices

64
Q

Single Quinta

A

In years when producers do not make Vintage Port, they may produce a Single Quinta Port. A wine from one year made from grapes only from one estate that is stated on the label (Taylors, Grahams)

65
Q

Crusted

A

A non vintage Port that is aged in wood for up to two years before being bottled. Without fining or filtration, hence a deposit or ‘crust’ from in the bottle

Botteling date must appear on the label, similar in style to Vintage Port and have considerable ageing potential.

Usually good to very good in quality and mid to premium priced

66
Q

Late Bottled Vintage (LBV)

A

LBV Ports are wines from a single year and must be bottled between 4 and 6 years after harvest. The fruit used for LBVs does not tend to be of the same quality as that for Vintage Ports. They are bottled ready to drink

Before botteling the wine is usually stored in large, old wooden vessels or stainless steel vats to avoid oxidation. Many LBV are filtered before bottling

Good to very good in quality, and usually mid priced. Tend to have a little more intensity, body and tannin than Ruby and Ruby reserve

Some LBVs are not filtered before bottling and tend to say unfiltered on the bottle

67
Q

Rose Port

A

Also called Pink Port, invented by Croft in the late 2000s

Made from black varieties, with grapes that tend to come from cooler areas, high altitude or form Baixo Corgo.

The must is left to macerate for only a few hours before draining and clarification. Fermentation takes palace at around 15-16 degrees to retain red berry fruit aromas

The aguardente used must be as neutral as possible

Wines are bottle soon after the fortification and release from the winery within a year. They tend to be inexpensive to mid-priced wines. Colour can range from pale salmon to almost ruby depending on the producer

68
Q

White Port unoxidized style

A

Muscatel tends to be one of the key varieties in the blend, lending aromatic fruity and floral notes

At the winery grapes are crushed, so2 is added and maceration last for a couple of hours at chilled temperatures to limit oxidation. Fermentation temperature is similar to those of used for unfortified whites at 18 degrees to enhance and retain fruity aromas

Stored in stainless steel or very large old wooden barrels for a short period. These Ports are often lemon in colour, medium bodied with flavours of stone fruits and floral notes

69
Q

White Port oxidized style

A

Typically Malvasia, with its subtle flavours in yought becoming honeyed and nutty with age

Wines spoed slightly longer on their skins to extract more phenolics that will support the wine during the ageing process. Aged for several years in small casks

Amber to even brown in colour and tend to show floors of caramel, citrus peel, dried fruits and nuts

70
Q

White Reserve

Q

The Beneficio

A

The amount of Port that can be produced in a year is highly regulated in a system called the Beneficio. The aim of the Beneficio system is to keep grape and wine prices sable through its influence of the balance of supply and demand

Each vineyard parcel is classified in terms of its capacity to produce quality grapes for Port, considering location, altitude, aspect, soil and grape varieties planted. The vineyard parcel receives a numerical value for each of one of these factors, and the final total is used to give the parcel al letter. This means that two vineyards located next to each other but planted with different grapes would likely gain different scores and possibly different letters. The parcels are given the letters A to I and the letter awarded determines the amount of Port wine. that can be made from on parcel; with A denoting the vineyards of the highest quality and therefore can produce the most Port wine. Vineyards with a rating below F cannot make port wine, but can be used for unfortified wines or distilled into spirits
