Final answer:
Sweet wines are generally not fortified. They can be produced through methods such as late harvest or botrytized grapes, or by stopping fermentation early.
Step-by-step explanation:
Fortification is not typically used in making sweet wine. Sweet wines are generally not fortified. They can be produced through methods such as late harvest or botrytized grapes, or by stopping fermentation early. Fortification refers to the process of adding extra alcohol (usually in the form of brandy) to wine to increase its alcohol content. This process is commonly used in the production of fortified wines such as port and sherry.
However, sweet wines can be made through other methods such as late harvest or botrytized grapes, where the grapes are left on the vine longer to increase their sugar content. Additionally, some sweet wines are made by stopping the fermentation process before all the sugars are converted to alcohol.
