Real-World Exam Episode
Why is 'Port' (Port) typically a sweet (Sweet) style of fortified wine?
- A. Large amounts of sugar are added after fermentation is fully complete.
- B. Brandy (Spirits) is added during fermentation to stop the activity of the yeast.
- C. Sun-dried grapes are used to concentrate the sugar content.
- D. Honey water is mixed in just before bottling.
Critical Answer & Explanation
Answer: B. Brandy (Spirits) is added during fermentation to stop the activity of the yeast. Explanation: Port wine is produced by adding high-proof alcohol (such as brandy) while fermentation is still underway. This high alcohol level kills the yeast, which halts the fermentation process. As a result, the natural sugar that has not yet been converted into alcohol remains in the wine, creating its characteristic sweetness. This process increases the overall alcohol content while preserving the wine's natural sugar.

Expert Mastery Theory
Core knowledge of fortification (Fortification) as defined by WSET Level 1: 1. Definition of Fortified Wine: A wine whose alcohol content has been increased (typically to 15–22% ABV) by the addition of neutral grape spirits (Spirits). 2. Controlling Sweetness through Timing: - Port: Alcohol is added during fermentation to retain unfermented sugar, resulting in a sweet style. - Sherry: Alcohol is typically added after fermentation is complete, which is why most Sherries are dry. 3. Preservative Qualities: Historically, the high alcohol content of fortified wines was intended to protect the wine from spoiling during long sea voyages.
Pass-Guarantee Tip
[Trap]: Avoid the generalization that "All fortified wines are sweet." Some styles of Sherry, such as Fino, are among the driest wines in the world. [Tip]: Whenever the term 'Port' appears, always look for the combination of 'Sweet' and 'Spirit added during fermentation.' If an exam question mentions the 'Interruption of fermentation,' it is almost certainly referring to the production of Port.
