Okay, so I tried my first batches of ejuice this weekend. I made a few flavors and steeped them in a crock pot. Whoa! I way overdid it with the flavoring. I made 15 % with an apple pie flavoring and it was way too strong. So, I cut it down to 5% by diluting with unflavored
juice. It doesn't taste horrible but apple pie...not really. It has more of a perfumy taste. Not totally unusable but not what I wanted. Any ideas?
Most ejuice is not made with a single flavor -- you need creams, vanilla, and sweetener, for most sweet vapes to taste good; if you use something like 25%-30% flavoring, you won't really *need* to steep, at least not more than a few hours/overnight. If you stay around 20% flavoring, a steep might be helpful, but you should taste it first, it might be fine, and then just put it in a dark place to steep, with regular shakings and tastings to know when it's good.
The advantage of using the higher volume of flavoring is that it actually does taste like something right away, so you can tell if you need to tweak the recipe.
Finding the flavors you actually like is mostly a matter of trial and error -- the different brands are generally very different on flavors that are labelled as being the same thing.
