Final answer:
A light style of rum can be produced by using commercial yeast, having a short fermentation time, and utilizing a relatively dilute wash. Collectively, all these factors contribute to the final lightness of the rum's style.
Step-by-step explanation:
The condition that should result in a light style of rum involves multiple factors during the distillation process. When we look at the specifics:
- Use of commercial yeast: This can lead to a cleaner, more consistent fermentation, which is a characteristic of light rum.
- Short fermentation time: This limits the production of heavier alcohols and congeners, which contributes to a lighter rum profile.
- Relatively dilute wash: A lower concentration of sugars and other materials in the wash can also lead to a lighter rum, as there is less to be fermented into the heavier alcohol components.
Considering these factors, all of the above options contribute to producing a light style of rum.
