The short version: port is a fortified wine from the Douro Valley — grape spirit is added mid-fermentation, which stops it and leaves the wine sweet and strong (around 20%). The main styles are Ruby, Tawny, White and Vintage, aged in the lodges of Vila Nova de Gaia opposite Porto. It’s classically a dessert or after-dinner wine.

What makes port different
Port is a fortified wine: during fermentation, before all the grape sugar turns to alcohol, winemakers add a neutral grape spirit (aguardente). This stops the fermentation, so the wine keeps its natural sweetness and jumps to around 19–20% alcohol. The grapes — Touriga Nacional, Touriga Franca, Tinta Roriz and others — come from the steep, terraced Douro Valley, one of the world’s oldest demarcated wine regions. The young wine is then brought downriver to age in the lodges of Vila Nova de Gaia, across from Porto.
The main styles
Two families, by how they age. Ruby-style ports age in tank or large vats to stay fruity and deep red — this includes basic Ruby, Reserve, LBV (Late Bottled Vintage) and, at the summit, Vintage Port from a single declared year, built to age for decades in bottle. Tawny-style ports age in small oak barrels, slowly oxidising to an amber colour with nutty, caramel and dried-fruit flavours; the best carry an age indication — 10, 20, 30 or 40 Years. There’s also White Port (from white grapes, lovely chilled or in a Port & Tonic) and pink Rosé.
How to drink it, and where
Serve Ruby and Vintage ports at cool room temperature with chocolate, berries or blue cheese; serve Tawny slightly cool with nuts, caramel desserts or on its own; and serve White Port chilled as an aperitif. The place to learn is the Gaia lodges — book a port cellar tour and tasting — and to see where it’s grown, take a Douro Valley day trip upriver. For the city’s food, see what to eat in Porto.
Sherry is port’s Spanish cousin — also fortified, but mostly dry and white; if you’re comparing the two, our sherry explained guide breaks down Fino, Oloroso and Pedro Ximénez.
