I have mixed feelings about steeping, pardon the pun.
For most flavors, it seems they are good to go right after mixing. I've tested this theory by trying three different deliver systems with a fresh mix:
- Atomizer + Cartridge
- Cartomizer
- Tank
Seems to me they all produce a good flavor right away, with the possible exception of the carto. It can take quite awhile before the juice fully absorbs into the carto batting. If I let it sit overnight that will typically take care of the problem. I can also poke the batting a bit with a needle cap bottle or a paper clip to speed the process along. It's just a matter of absorbtion.
Now the exception to the rule seems to be tobacco flavored juices, especially those with a very heavy flavor. Those do seem to change a bit over time. The difference between day one and day five might be very subtle, but I think I can really tell a difference.
But there are also times when I think it's just me. Like everyone else, my taste buds change. Sometimes I suspect things are tasting a little unusual and I'll go back to some trusty standby's like Watermelon or Peach. If these lighter flavors are tasting a little off that particular day I'll know to stop testing. Just wait for another day when things are back to normal and give it a go again.
So in general I think steeping is just a myth. But there's always that little voice in the back of my mind that tells me the jury is still out. It's kind of like going to the fridge and grabbing my favorite beer. Most days that beer tastes pretty darned good. But every once in awhile it tastes a little off.
The best solution: have another beer.
