If a solute is very soluble in a solvent (ethanol), why doesn't crystallization occur?
I attempted to recrystallize 14 g of solute A in 30 mL of ethanol, but crystallization didn't occur. Why?
Is it because a) the solution is supersaturated or b) because there is too much solvent? How can I tell which of the two reasons is to blame?

More than likely it isn't supersaturated. The probable cause is too much solvent. Let some of the solvent evaporate.
If you want to check to see if it is supersaturated, drop a crystal of the solute into the solution. If it is supersaturated the solute should crystallize immediately.
