Port wine in two minutes

What port is, why the glass at a fado show is a small one, and where the wine trade stands on the opposite bank.

Quick answer

Port is a Douro Valley wine whose fermentation is halted by adding neutral grape spirit, which leaves it sweet and strong, so a single small pour is ample for an hour of music. The cellars, known as lodges, stand on the far bank of the Douro in Gaia.

What port is

According to Wikipedia, port is a fortified wine from northern Portugal's Douro Valley, typically sweet and red, and usually between 19 and 22 per cent alcohol. The wine is stopped mid-fermentation by a neutral grape spirit, which keeps sugar in it and lifts the strength.

Ruby, tawny and white

Wikipedia puts ruby and tawny first among the red kinds: rubies are younger, tawnies are aged longer in barrel. White ports are made from a different set of grapes than the reds. Which one fills your glass in a fado room is the venue's choice, and the listing does not say.

Why Gaia, and why Porto

Wikipedia says the wine took its name from the harbour city of Porto, where it went to market, and that the ageing cellars stand in Gaia on the opposite bank. Until 1986 it could only be exported from Gaia. The two cities face each other across the Douro, joined by the Dom Luís I Bridge.

The rabelo boats

Wikipedia describes the rabelo as a wooden, flat-bottomed freight boat that moved goods, wine among them, down the Douro, and that port companies still keep some on the river in Porto and Gaia. Every year on 24 June a race of rabelos is held on St John's Day.

Drinking it

Wikipedia says port, apart from white, should be served at between 15 and 20 degrees Celsius. In a fado room the question is moot: one glass arrives, and the point is to sip slowly alongside the music.
