Why may only Portuguese wine be called port?
Port is a protected designation of origin. Only fortified wine from the Douro in northern Portugal may be called port or porto, controlled by the Instituto dos Vinhos do Douro e Porto. The Douro was demarcated in 1756 and is regarded as the oldest regulated wine region in the world. Fortified wine from elsewhere may not use the name and is called, for example, sherry, madeira or marsala.

What does a protected designation of origin mean for port?
A protected designation of origin ties a name to an area and to a method of production, and prohibits the use of that name for wine from outside that area.
For port, the European basis lies in Regulation (EU) No 1308/2013. That regulation governs how wine names are recognised and protected. The recognised names are in eAmbrosia, the public register of the European Commission.
Anyone who makes fortified wine outside the Douro must therefore put a different name on the label. The name port cannot be freely used for a wine that merely resembles it.
Where is the area that port may come from?
Port comes from the demarcated Douro region in the north of Portugal, the valley of the Douro river behind the city of Porto.
The IVDP calls that region the oldest demarcated and regulated wine region in the world, with 1756 as the year of demarcation. The area is on UNESCO’s World Heritage list.
The grapes come from that region and the wine is made there. The IVDP checks the origin and quality, and oversees the production process.
How does port differ from other fortified wine?
Port is made by stopping fermentation with grape spirit, which leaves natural grape sugar in the wine and raises the alcohol content.
The IVDP calls that addition benefício and states that port usually contains between 19 and 22 percent alcohol.
Sherry from Andalusia is only fortified after fermentation and in the dry styles is precisely not sweet. Madeira comes from the island of the same name. Each of those wines has its own protected name and its own regulator.
What is on the label of a bottle that may not be called port?
Fortified wine from outside the Douro carries its own name: sherry from Andalusia, madeira from the island of Madeira, marsala from Trapani, or simply the designation fortified wine.
In the Netherlands you will also come across bottles labelled aperitif or fruit wine. These do not fall under the port rules and are made differently.
Look at the label for the statement of origin. For port, the bottle says Porto, Port or Vinho do Porto, together with the origin from Portugal.
Why does the bottle sometimes say porto and sometimes port?
Porto and port are both recognised spellings of the same protected name; which form you see depends on the language area for which the bottle is intended.
Portuguese labels often say Vinho do Porto or Porto. In Dutch- and English-speaking areas, port is the usual form. It is the same wine and the same rules.
What else is on the label concerns the style: ruby, tawny, white or rosé, or a special category such as LBV, vintage or colheita.
