Step-by-step explanation:
The function of a retort in pot distillation of rum is to increase alcoholic strength and add flavor components.
In the process of pot distillation, a retort is used to heat the fermented mixture of rum to vaporize the alcohol. The vapor then passes through a condenser and collects in a separate container, resulting in a higher concentration of alcohol. Additionally, the process of distillation can also contribute to the development of flavor components in the final product.
