Final answer:
The sweet fortified wine known as Port from Portugal is typically made from five main grapes: Touriga Nacional, Touriga Franca, Tinta Barroca, Tinta Roriz (Tempranillo), and Tinta Cão, which contribute to its rich and concentrated flavors.
Step-by-step explanation:
The five main grapes used to make the sweet fortified wine known as Port from Portugal are:
- Touriga Nacional
- Touriga Franca
- Tinta Barroca
- Tinta Roriz (also known as Tempranillo)
- Tinta Cão
These grapes are typically grown in the Douro Valley of Northern Portugal and are renowned for their ability to produce the rich, concentrated flavors that are characteristic of Port wine.
The fortification process involves the addition of grape spirit to the wine, which stops fermentation and retains a high level of natural sweetness from unfermented grape sugars.
