Port is one of the few drinks where the style name on the label tells you almost everything that matters. It tells you how the wine was aged, roughly how old it is, whether it will keep once opened, and what it should be served alongside. The trouble is that nobody explains the vocabulary, so the shelf reads like a wall of near identical bottles.
This guide takes the six styles you will actually encounter in Australia and explains what separates them. Every style is illustrated with a bottle from our Port range, which is drawn entirely from Kopke, the oldest Port house still operating.
First, what Port actually is
Port is a fortified wine from the Douro Valley in northern Portugal. The Douro was formally demarcated in 1756, making it one of the oldest regulated wine regions anywhere in the world. The vineyards are terraced into steep schist hillsides above the river, and the grapes are mostly indigenous Portuguese varieties: Touriga Nacional, Touriga Franca, Tinta Roriz, Tinta Barroca and Tinto Cao.
What makes it Port is the fortification. Partway through fermentation, while a good deal of grape sugar is still unconverted, the winemaker adds neutral grape spirit. The alcohol stops the yeast in its tracks. Fermentation ends early, the unfermented sugar stays in the wine, and the result is a wine that is both sweet and strong. Everything that happens after that point is a question of how, where and for how long the wine is aged.
That single question splits Port into two families. Wines aged in a way that limits contact with air stay red, fruity and youthful. Wines aged in a way that encourages contact with air turn brown, lose their fruit and gain nuttiness. Almost every style name is a position on that spectrum.
Ruby: the fresh, fruit driven end
Ruby Port is aged in large vats or tanks for a short period, usually two to three years. The volume is large relative to the surface area, so very little oxygen reaches the wine. It goes into the bottle still deep red and still tasting of the fruit it was made from: blackberry, plum, dark cherry.
This is the entry point to the category and it is the style that works best in cocktails and in cooking. Kopke Ruby Port is the straightforward expression, while Kopke Reserve Ruby steps up a grade. Reserve is a defined term rather than marketing language: a Reserve Ruby is a premium blend that has been submitted to and approved by the Instituto dos Vinhos do Douro e do Porto tasting panel, and it typically carries more concentration and a longer finish than a standard Ruby.
LBV: a single harvest, held back in wood
Late Bottled Vintage sits between Ruby and Vintage Port. The wine comes from a single year's harvest, and instead of being bottled after two or three years it is held in wood for four to six before release. The extra time softens the tannin and rounds out the structure, which is the whole point: LBV was conceived as a wine that gives you something of the character of a Vintage Port without needing a decade in your cellar first.
Kopke LBV Porto is the house's expression of this. It is the style to reach for if you want a red Port with real depth to drink now, and it is the most natural partner for a strong blue cheese.
Tawny: the oxidative side
Tawny Port is aged in seasoned oak casks called pipes, which hold roughly 550 litres. The smaller volume means far more of the wine touches wood and air. Over years the colour fades from red through amber to a pale russet brown, the fresh fruit recedes, and in its place come walnut, dried fig, caramel, orange peel and toffee.
The simplest expression is a straightforward blend such as Kopke Fine Tawny Port, with Kopke Reserve Tawny as the step up.
Above those sit the age indicated Tawnies, and this is where a common misunderstanding needs clearing up. When a bottle says 10, 20, 30 or 40 Years Old, that number is not the age of the youngest component and it is not a minimum. It is a statement of the blend's average age profile, assessed and approved by the regulating body. A 40 Year Old Tawny is a blend assembled to taste like a forty year old Port, and it may contain both older and younger material.
The differences between the tiers are real and easy to taste side by side. Kopke Tawny 10 Year Old still has visible fruit under the nuttiness. Kopke Tawny 30 Year Old has traded almost all of it for concentration and dried fruit intensity. Kopke Tawny 40 Year Old is thick, almost syrupy, with the volatile orange peel lift that very old Port develops.
Colheita: the style most people have never heard of
A Colheita is a Tawny Port from a single harvest year. Where an age indicated Tawny is a blend built to a house style, a Colheita is one year, aged oxidatively in cask for a minimum of seven years and often for very much longer, then bottled with both the harvest year and the bottling date on the label.
This is the most interesting corner of the category and it is also the one most closely associated with Kopke, who have built their reputation on it. Because the wine is aged in cask rather than bottle, a Colheita does not need decanting and does not require further cellaring: it was ready the day it was bottled. Kopke Colheita Port is the entry into the style.
If you are buying a bottle to mark a particular year, a Colheita is worth knowing about, because it carries a genuine harvest date rather than an approximation. It sits alongside the other single year options we cover in our guide to buying a bottle from the year you were born.
White Port: the one to put in a glass with tonic
White Port is made the same way as red Port but from white Douro grapes, chiefly Malvasia Fina, Viosinho, Gouveio and Rabigato. Depending on how it is handled it can be dry, off dry or sweet.
Its moment came when Portuguese bars started serving it long, over ice with tonic water and a slice of lemon, as a Porto Tonico. It is an excellent hot weather aperitif and it makes far more sense in an Australian summer than a room temperature glass of Ruby. Kopke White Port is the bottle for this.
Serving, and how long an open bottle lasts
Temperature does more for Port than almost any other adjustment. Tawny and Colheita are best served lightly chilled, somewhere around 12 to 16 degrees, which lifts the aromatics and stops the sweetness turning cloying. Ruby, Reserve and LBV are better a touch cooler than a typical Australian room, so half an hour in the fridge before pouring. White Port should be properly cold, or over ice.
The more useful question is how long a bottle survives once opened, and the answer follows directly from how the wine was aged. Tawny and Colheita have already spent years in contact with oxygen, so a little more does nothing dramatic: an open bottle holds up for one to three months. Ruby, Reserve and LBV have been protected from air, so they fade faster, typically over two to four weeks. Keep both in the fridge with the cork in.
For food, the classic pairings hold up. Tawny with almonds, dried figs, creme brulee or a hard aged cheddar. LBV or Ruby with dark chocolate or Stilton. White Port with olives and salted almonds before dinner.
Where to start
If you have never bought Port deliberately, buy a 10 Year Old Tawny and a Reserve Ruby and drink them a week apart. They sit at opposite ends of the same spectrum and the contrast will tell you more in two evenings than any tasting note. From there, the full Kopke range gives you every step in between.
If fortified wine in general is the thing that interests you, the same oxidative logic drives our Sherry range, where Oloroso and Palo Cortado play a comparable role to Tawny Port.
