What each ingredient does

Mealy boiled potatoes
Provide starch and bulk that the yeast converts into sugars and alcohol.
White flour
Adds extra starch and body to the batter, giving the yeast more material to work on.
Baker's yeast
Ferments the sugars, producing carbon dioxide for rising and alcohol for the wine.

The step that matters

Let the mixture rise until light. Yeast needs time and warmth to ferment sugars into gas and alcohol. Rising until light shows fermentation is active, and sealing the bottles too early can build pressure.
