I have read a lot of comments from people stating they steep for up to a month or more. Call me crazy, or just a noob, but I never have noticed a difference in flavor after a day or 2 at most.
Depends on the juice and the person. For me, personally, I ALWAYS try the juice right away... just to see what it's like. (and I'm impatient) If it's good, I may start vaping it. If not, I'll set it aside and keep checking on it periodically. Some liquids to me have been horrible right away (especially ones I mix myself). However, after a week to a month (tobaccos and desserts mainly) they drastically improve or change altogether. Some vendors presteep or premake their juice while others are made to order. I am also guessing that nicotine is a factor (I will soon be doing an experiment to see if it is). It seems that nicotine enhances, alters or at the least, expedites the steeping process. I don't vape nicotine and it seems like most of my juices take longer to steep/come to fruition than others. If you anyone is interested, I will come back and let you know if the nicotine/no nicotine flavor test yields any results. I'm just personally curious to know.
