Living organisms like yeast are responsible for converting sugars into alcohol. If you add too much, or in the wrong order, you can kill the yeast and end the process. The aging process happens after... when the distillation is done. It's a lot like making tea. You put the liquor into oak barrels (or casks or some similar) and the wood and char mix with the liquor (just like a tea bag will mix with the water when making tea).
