What each ingredient does

Coarse sugar
Provides the sugar that yeast ferments into the acids that make the vinegar.
Spring water
Forms the liquid base in which the sugar dissolves and the fermentation takes place.
Yeast
Converts the sugar into alcohol and starts the fermentation that later turns into acetic acid.

The step that matters

Adding the yeast-spread toast at the right temperature. The mixture should be cool when the yeast is added, because hot liquid can kill yeast cells. Cooling the sugar water first keeps the yeast alive so it can start fermenting the sugar.
