Port

The Diploma is finally nearing its close! I have just one unit left to complete which is on fortified wine, one of my favourite subjects. The main focus of the unit is port and sherry, but I will also be studying madeira, the vins doux naturels of southern France, and the unique and often extraordinary stickies of Rutherglen in Australia. This week I have been focusing on port, its history, and its different styles, indulging in a tasting of five different wines to help understand the varied styles.

a bit of history

Like sherry and madeira, port emerged through trade and war. When England and France were at loggerheads in the seventeenth century, French goods, including wine, were subject to sanctions and high taxes. To sate England's thirst for wine, the English turned to one of its European allies, Portugal. After finding the coastal red wines of Vinho Verde too astringent, English merchants went further inland to the Douro Valley and its rich, ripe, full-bodied red wines. The wines were shipped to England in barrels (the practice of bottling wine on site and shipping it in bottles had not yet been developed); to ensure that the wines arrived in good condition, brandy was added to the wine.

This strong, high alcohol wine proved extremely popular and the practice of fortifying the wines became standard. Although at the height of port's popularity practices were wayward - the wines were fortified to an extra strength for the English market and often had elderberries added - various styles of port emerged which exist today.

the area

Port is made in the Douro Valley, whose boundaries still mostly follow local politician Marquis de Pombal's 1756 designation. The soils are schist, a form of slate, on steep terraced slopes on the banks of the river. The valley is divided into three areas: the Baixo Corgo, which is cool and wet and produces the lightest, most inexpensive ports; the Cima Corgo, which is warmer and drier and produces the most complex wines; and the Douro Superior, which is hot and dry and the focus of recent plantings as it is flatter and easier to maintain.

how it's made

Port is a sweet wine because it is fortified with a grape-based spirit (called aguardamente in Portuguese) during the fermentation. The high alcohol (77% ABV) kills the yeast in the wine with sugar still remaining. There are over 80 permitted grape varieties allowed for port, which were traditionally grown together in vineyards without anyone really knowing what was what. Since the 1970s, five varieties in particular have been identified as being ideal: Touriga Nacional (low yields, high tannins, very perfumed), Touriga Franca (the most planted), Tinta Roriz (Spain's Tempranillo, adding colour and body), Tinta Barroca (high alcohol, low acidity), and Tinta Cão (literally "red dog"). Port is always a blend of different grapes, each of which brings different qualities to the wine.

the styles

ruby

Simple, inexpensive, fiery, fruity, and young, ruby was until the 1960s drunk by the British with lemonade. It's now most popular in France where it's served as an aperitif. There's also ruby reserve, a higher quality version introduced in the late 1960s by Cockburn's after the British taste for ruby and lemonade faded.

late bottled vintage

LBV for short, it's a port which has been aged for four to six years in old oak barrels before release. It comes in three different styles. The most common is filtered before bottling and has a stopper; the second isn't filtered, has a cork, and generally needs decanting; the third is aged in bottle for three years before release and can be similar to a vintage port in style. Like vintage port all the grapes come from one year and the wines have a similar fruity, tannic intensity, but even the best LBVs lack the heady concentration of a vintage port as they are made every year, not just those that are outstanding.

vintage

Made only in years a producer considers outstanding, when a warm summer produces grapes of optimum ripeness. Vintages are declared around three times a decade, although some producers will declare a year a vintage while others may not. The wine is aged in old oak barrels for three years before bottling (unfiltered, which is why vintage port needs decanting). After that, it's up to the customer to age the wine: vintage port can be at its best at fifty years' old even though it's released so young.

tawny

This is my favourite style of port, perhaps because it's deliberately oxidised like sherry. Its name comes from its colour, the deep ruby port fading in the barrel due to the exposure to oxygen. Inexpensive tawnies are put out in the sun to quicken the ageing, but the best wines are aged gradually over time to develop a nutty complexity. These usually have an age indication of 10, 20, 30, or 40 years (which is an indication of the wine's average age, as tawnies are non-vintage). A vintage tawny is called a colheita (Portuguese for harvest), which has to be aged for at least seven years. It displays the character of the vintage as well as the nutty maturity of an aged tawny.

the tasting

 

Passagem Ruby Reserve NV ($18)

Simple, but at this price very appealing. Fruity, jammy red and black fruits with spicy alcohol on the palate. ✪✪✪

Quinta do Infantado Late Bottled Vintage 2009 ($24) 

For a few dollars more and from an extremely good year, this wine offers a lot more complexity with aromas of liquorice and cloves, irises, blueberries and blackberries, and dried fruit aromas of figs and prunes, with a gripping tannic structure. Intense, but very approachable. ✪✪✪✪✪

Quinta do Infantado 10-year-old Tawny ($41)

My wine of the tasting. Incredibly pronounced, concentrated aromas of every dried fruit imaginable: cranberries, strawberries, raspberries, figs, prunes, currants, and raisins, with spice aromas of cinnamon, cloves, anise, and liquorice. The tannins are faded, but the acidity is high enough to balance the sweetness. ✪✪✪✪✪✪

Niepoort 1999 Colheita ($52)

After the tawny, this was somewhat disappointing - perhaps a reminder that just because a wine has a vintage on the label doesn't make it superior (the same is true in Champagne). The aromas were similar to the tawny - floral and with dried fruits - but lacked the same intensity. ✪✪✪✪

Quinta do Infantado 2007 Vintage Port ($50) 

When I bought this wine I knew it would be far too young, but old vintage port is not easy to come by at an affordable price. This wine was really closed and tight and difficult to assess, but nevertheless lots of complex aromas emerged: brambles and blackberries, mint and lavender, cloves and nutmeg, black pepper and liquorice, sultanas and raisins, and strawberries, redcurrants, and raspberries. I'd love to taste this in another ten or even twenty years. ✪✪✪✪✪

It's remarkable how different these styles of port are: the fruity, hot ruby, compared to the closed, difficult, and still young vintage, in contrast to the tannic, concentrated LBV; and then there's the faded colours of the tawny and colheita, offering a reserved, intense maturity. The range of these styles are perhaps confusing to many consumers, but understand the label and there's a wealth of choice in these wines.
