rootstock, with the notable exception of the Nacional area of Quinta do Noval, which, since being planted in 1925, has produced some of the most expensive vintage ports. Grapes grown for port are generally characterized by their small, dense fruit which produce concentrated and long-lasting flavours, suitable for long aging. While the grapes used to produce port made in Portugal are strictly regulated by the Instituto do Vinho do Porto, wines from outside this region which describe themselves as port may be made from other varieties.


Sales

In 2013, there were 8.7 million cases of port sold, 3.6% less than the previous year, at a value of $499 million. Port sales have been declining since 2005 and are down 16% from that year. Declining sales are attributed by some to increasing prices, due to the increased cost of alcohol used in the production process. Declining sales have also been attributed to the global rise in alcohol levels of table wines. As of 2014, the leading brand in Portugal is Cálem, which sells 2.6 million bottles annually.


Transport

Port is produced from grapes grown in the Douro valley. Until 1986 it could only be exported from Portugal from

Properties

Port wine is typically richer, sweeter, heavier, and higher in alcohol content than unfortified wines. This is caused by the addition of distilled grape spirits that fortify the wine, but also halt fermentation before all the sugar is converted to alcohol, and results in a wine that is usually 19% to 20% alcohol.

in English-speaking countries, often with cheese, nuts, and/or chocolate; white and tawny ports are often served as an apéritif. In Europe all types of port are frequently consumed as apéritifs.


Styles

Port from Portugal comes in several styles, which can be divided into two broad categories: wines matured in sealed glass bottles, and wines that have matured in wooden barrels. The former, without exposure to air, experience what is known as "reductive" ageing. This process leads to the wine losing its color very slowly and produces a wine which is smoother on the palate and less tannic. The latter, being matured in wooden barrels, whose permeability allows a small amount of exposure to oxygen, experience what is known as "oxidative" aging. They too lose color, but at a faster pace. They also lose volume to evaporation (

), leaving behind a wine that is slightly more viscous. The IVDP ('' Instituto dos Vinhos do Douro e Porto'') further divides port into two categories: normal ports (standard rubies, three-year-old tawnies, and white ports) and ''Categorias Especiais'', special categories, which include everything else.


Ruby

The most common type, ruby port is stored in tanks of concrete or

after fermentation, to prevent oxidative aging and preserve its bright red color and full-bodied fruitiness. The wine is usually blended to match the style of the brand to which it is to be sold. The wine is fined and cold filtered before bottling and does not generally improve with age, although premium rubies are aged in wood from four to six years.


Reserve

Reserve ruby is a premium ruby port approved by the IVDP's tasting panel, the ''Câmara de Provadores''. In 2002 the IVDP prohibited the use of the term "vintage character", as reserve ruby port had neither a single vintage (usually being a blend of several vintages of ruby) nor the typical character of vintage port.


Rose

Rose port is a very recent variation on the market, first released in 2008 by Poças and by Croft, part of the Taylor Fladgate Partnership. It is technically a ruby port, but fermented in a similar manner to a rosé wine, with a limited exposure to the grape skins, thus creating the rose color.


Tawny

Tawny ports are wines usually made from red grapes that are aged in wooden barrels exposing them to gradual oxidation and evaporation. As a result of this oxidation, they mellow to a golden-brown color. The exposure to oxygen imparts "nutty" flavours to the wine, which is blended to match the house style. They are sweet or medium dry and typically consumed as a dessert wine, but can also pair with a main course. When a port is described as tawny, without an indication of age, it is a basic blend of wood-aged port that has spent time in wooden barrels, typically at least three years. Reserve tawny port (produced by Borges, Calem, Croft, Cruz,

, Kopke and other houses) has been aged about seven years. Above this are tawnies with an indication of age, which represent a blend of several vintages. The target age profile, in years in wood, is stated on the label, usually 10, 20, 30 or 40 years. These ports are produced by most houses. It is also possible to produce an aged white port in this manner, with some shippers now marketing aged white ports. In some places, such as Canada and Australia, tawny may also be used to describe any port-style wine that is not produced in Portugal as per agreement with EU.


Colheita

Colheita port is a single-vintage tawny port aged for at least seven years, with the vintage year on the bottle instead of a category of age (10, 20, etc.). Colheita port should not be confused with vintage port: a vintage port will spend only about 18 months in barrels after harvest and will continue to mature in bottle, but a Colheita may have spent 20 or more years in wooden barrels before being bottled and sold. White Colheitas have also been produced.


Garrafeira

Unusual and rare, vintage dated Garrafeira combines the oxidative maturation of years in wood with further reductive maturation in large glass demijohns. It is required by the IVDP that wines spend some time in wood, usually between three and six years, followed by at least a further eight years in glass, before bottling. In practice the times spent in glass are much longer. The style is associated with the company Niepoort, although others do exist. Their dark green demijohns, known as bon-bons, hold approximately each. Some connoisseurs describe Garrafeira as having a slight taste of bacon, the reason being that, during the second phase of maturation, certain oils may precipitate, causing a film to form across the surface of the glass. Confusingly, the word Garrafeira may also be found on some very old tawny labels, where the contents of the bottle are of exceptional age.


White port

White port is made from white grapes, such as ''Malvasia Fina'', ''Donzelinho'', ''Gouveio'', ''Codega'' and ''Rabigato'', and can be made in a wide variety of styles, although until recently few shippers have produced anything other than a standard product. Ordinary white ports make an excellent basis for a cocktail while those of greater age are best served chilled on their own. Sweet white port and tonic water is a commonly consumed drink in the Porto region. There is a range of styles of white port, from dry to very sweet. Taylor's introduced Chip Dry, a new style of white apéritif Port, in 1934. Made from traditional white grape varieties, it is fermented for longer than usual to give it a crisp dry finish. Lágrima, which means "tears", is the name for the sweetest style of white Port. In addition to this type of wine, there is the White Port Colheita, which is obtained from a single harvest and ages in huge tanks acquiring a straw color, has mature and elegant aromas and flavours, featuring fruity and wooden notes, and the White Port with an indication of age, which is an elegant, full-bodied and rich Port, obtained from the blend of different wines with the same average age. When white ports are matured in wood for long periods, the color darkens, eventually reaching a point where it can be hard to discern (from appearance alone) whether the original wine was red or white.


Late bottled vintage

Late bottled vintage (often referred to simply as LBV) was originally wine that had been destined for bottling as vintage port, but because of lack of demand was left in the barrel for longer than had been planned. Over time it has become two distinct styles of wine, both of them bottled between four and six years after the vintage, but one style is fined and filtered before bottling, while the other is not. The accidental origin of late bottled vintage has led to more than one company claiming its invention. The earliest known reference to a style of port with this name in a merchant's list is to be found in The Wine Society's catalogue from 1964, which includes Fonseca's Quinta Milieu 1958, bottled in the UK, also in 1964. By the 1962 vintage, LBV was being produced in Portugal and bottled as LBV. LBV is intended to provide some of the experience of drinking a vintage port but without the need for lengthy bottle ageing. To a limited extent it succeeds, as the extra years of oxidative ageing in barrel does mature the wine more quickly.


Unfiltered

Unfiltered LBVs are mostly bottled with conventional driven corks and need to be decanted. After decanting they should be consumed within a few days. Recent bottlings are identified by the label "unfiltered", or "bottle matured", or both. Since the 2002 regulations, bottles that carry the words "bottle matured" must have enjoyed at least three years of bottle maturation before release. Before 2002 this style was often marketed as '"traditional", a description that is no longer permitted. Unfiltered LBV will usually be improved by extra years in the bottle. It can age as long as Vintage Ports and are very difficult to identify as LBVs when inserted into blind tastings of Vintage Ports.


Filtered

The filtered wine has the advantage of being ready to drink without

and is usually bottled in a stoppered bottle that can be easily resealed. However, many wine experts feel that this convenience comes at a price and believe that the filtration process strips out much of the character of the wine. Typically ready to drink when released, filtered LBV ports tend to be lighter bodied than a vintage port. Filtered LBVs can improve with age, but only to a limited degree.


Crusted

Crusted port is usually a blend of several vintages. Unlike vintage port, which has to be sourced from grapes from a single vintage, crusted port affords the port blender the opportunity to make best use of the varying characteristics of different vintages. Crusted port is bottled unfiltered, and sealed with a driven cork. Like vintage port it needs to be decanted before drinking.


Vintage port

Vintage ports may be aged in barrels or stainless steel for a maximum of two and a half years before bottling, and generally require another 10 to 40 years of aging in the bottle before reaching what is considered a proper drinking age. Since they are potentially aged in cask for only a short time, they retain their dark ruby color and fresh fruit flavours. Particularly fine vintage ports can continue to gain complexity for many decades after they were bottled. It is not uncommon for 19th-century bottles to still be in perfect condition for consumption. The oldest known vintage port still available from a shipper is the 1815 Ferreira. A tasting in 1990 described it as having an "intensely spicy aroma – cinnamon, pepper and ginger – hints of exotic woods, iodine and wax." Vintage port is made entirely from the grapes of a declared vintage year. While it is by far the most renowned type of port, from a volume and revenue standpoint, vintage port accounts for only about two percent of overall port production. Not every year is declared a vintage in the Douro. The decision on whether to declare a vintage is made early in the second year following the harvest. The decision to declare a vintage is made by each individual port house, often referred to as a "shipper." Much of the complex character of aged vintage port comes from the continued slow decomposition of grape solids in each bottle. These solids are undesirable when port is consumed, and thus vintage port typically requires a period of settling before decanting and pouring.


Single quinta vintage port

Single quinta vintage ports are wines that originate from a single estate, unlike the standard bottlings of the port wine houses which can be sourced from a number of quintas. Single quinta bottlings are used in two ways by producers. Most of the large port wine houses have a single quinta bottling which is only produced in some years when the regular vintage port of the house is not declared. In those years, wine from their best quinta is still bottled under a vintage designation, rather than being used for simpler port qualities.

s, where (primarily) Bordeaux producers release a year-labelled top wine almost every year, but also lesser quality wines in some years. If a port house decides that its wine is of quality sufficient for a vintage, samples are sent to the IVDP for approval and the house declares the vintage. In very good years, almost all the port houses will declare their wines. In intermediate years, the producers of blended vintage ports will not declare their flagship port, but may declare the vintage of a single quinta, e.g., the 1996 Dow's Quinta do Bomfim and Taylor's Quinta de Vargellas. Some houses declare their wines in all but the worst years: Quinta do Vesuvio has declared a vintage every year with the exceptions of 1993, 2002 and 2014. Improved wine-making technologies and better weather forecasts during the harvest have increased the number of years in which a vintage can be declared. Although there have been years when only one or two wines have been declared, it has been over thirty years since there was a year with no declarations at all. 2016 was declared a vintage year by most producers, as was 2011. The quality of the grape harvest was attributed to ideal rainfall and temperature. Other recent widely declared vintage years were 2007, 2003, 2000, 1997 and 1994.

In 1756, during the rule of the Marquis of Pombal, the Companhia Geral da Agricultura das Vinhas do Alto Douro (C.G.A.V.A.D., also known as the General Company of Viticulture of the Upper Douro or Douro Wine Company), was founded to guarantee the quality of the product and fair pricing to the end consumer. The C.G.A.V.A.D. was also in charge of regulating which port wine would be for export or internal consumption and managing the protected geographic indication.J. Robinson (ed) ''"The Oxford Companion to Wine"'' Third Edition pp. 536–540 Oxford University Press 2006 In 1678, a Liverpool wine merchant sent two new representatives to Viana do Castelo, north of Oporto, to learn the wine trade. While on a vacation in the Douro, the two gentlemen visited the Abbot of Lamego, who treated them to a "very agreeable, sweetish and extremely smooth" wine," which had been fortified with a distilled spirit. The two Englishmen were so pleased with the product that they purchased the Abbot's entire lot and shipped it home.Tom Stevenson ''"The Sotheby's Wine Encyclopedia"'' The Fourth Edition p. 334 DK Publishing 2007 Port became very popular in England after the Methuen Treaty of 1703, when merchants were permitted to import it at a low duty, while war with France deprived English wine drinkers of

. British importers could be credited for recognising that a smooth, already fortified wine that would appeal to English palates would survive the trip to London. The continued British involvement in the port trade can be seen in the names of many port shippers and brands: Broadbent, Cockburn, Croft, Dow, Gould Campbell, Graham, Osborne, Offley, Sandeman, Taylor, and Warre being amongst the best known. Shippers of Dutch and German origin are also prominent, such as Niepoort and Burmester. The British involvement grew so strong that they formed a trade association that became a gentlemen's club. A few port shippers and producers were also established by native Portuguese families: Ferreira and Quinta do Crasto are among the best. Both Ferreira and Quinta do Crasto can be credited for pioneering the Douro as a table-wine-producing region, Ferreira making Barca Velha since 1952 and Quinta do Crasto becoming the second producer of note, starting in the early 1990s.


Storing and serving

Port, like other wine, should be stored in a cool but not cold, dark location (as light can damage the port), at a steady temperature (such as a cellar), with the bottle laid on its side if it has a cork, or standing up if it is stoppered.Portwine.com – Storing

A traditional method of opening vintage port is with port tongs. The tongs are heated over a flame and applied to the bottle's neck. The bottleneck is cooled with cold water, causing a clean break. This avoids the use of a corkscrew on an older cork, which would otherwise break apart and crumble into the wine. Once opened, port generally lasts longer than unfortified wine, but it is still best consumed within a short period of time. Tawny, ruby, and LBV ports may keep for several months once opened; because they are aged longer in barrels, these ports have already been exposed to some degree of

Port houses

Producers of port wine are often called "shippers". In the early history of the port wine trade, many of the most powerful shipping families were British (English and Scottish) and Irish; this history can still be seen in the names of many of the most famous port wines. Over the years Portuguese, as well as Dutch and German owned shippers have also become prevalent in the port industry.
