How much steeping do they need?

[Holly Yoho]

I got four flavors and they all taste off so far, when should I try 'em again?

I'm an impatient vaper, too. I load a cartomizer or mini tank right away to try, and if it's not good, I just set aside the bottle and the carto/tank. I'll try again in about a week. If it's still not good, the bottle goes into storage for a month or so. I either clean out the sample carto/tank (if the flavor is repulsive) or add other stuff to make it vape-able if it's not too horrible.

I like to use Smoktech shorty cartridges for this. I label them with masking tape and write the juice name and date on there. I have an eyeglass case full of them, and sort through them now & then to try again or clean them.

Sounds like a convenient method.
