I understand what steeping does and many of the methods of doing it, but what does it exactly do? Is it just time for the flavors to blend? If that's it, then could you blend the flavors ahead of time and just mix it with PG/VG for a short time and vape? Do the chemicals break down in PG/VG and mature? Last question. How to the manufacturers do it? I would guess that they mix and set it on a shelf but we all know that time is money so I know someone has better secrets that "place in a dark, cool room".
