Is steeping really necessary for freshly-made juice? It seems strange to me. Most flavoring used in vape is PG-based. If you are adding it to PG, you are in essence just thinning it out. Why would thinning out flavoring require steeping?
Flavoring is often made will ethanol as its solvent instead of PG, or a combination of ethanol and PG. Even if you put it into VG instead of PG, you are just thinning it out. I can't understand why it has to sit for a few days. If you put aroma molecules into a solvent like PG and agitate it (shake it), you now have a solution, right? So once it is in solution, what difference could it possibly make if you let it sit? I cannot see the chemical reasoning behind this. Once it is in a soluble state, what more needs to be done? Nothing, I would think.
