@ChiDi621 — I don’t know what eliquid you are asking about. The Charlie Noble ones (Stroopwaffel and Pistachio RY4) for myself I find that I like it the best with at least a minimum of three weeks or more steep. The pistachio flavor had dropped slightly and this was perfect for me. For Stash Valhalla, I started vaping that one after two weeks steep and continued until it was gone. I currently have a second bottle steeping so will start vaping it sometime this week maybe. I have some other Stash eliquids that are new to me. One of them, Cinnamon Girl I tried after one week and did not care for it at that point so back to steeping. A few others from Stash I have not tried yet that are steeping — Southbound and PB&J. I am trying Sleeping Dragon for the first time however many others on this forum are oldtimers — I am always the last to try. I have Daft Spunk and Lemony Spunket plus a sample of Skeleton Key (key lime) steeping. These are 50/50 eliquids as I am trying to reduce my intake of VG so hoping I like them.
As a general rule I do not vape FOOB but a lot of people do. I do remove the cap for a few hours or overnight if I forget — I don’t think it matters at least for me it doesn't. From there I shake the bottle once a day if I remember. Otherwise whenever I think about it. After three or four times shaking I generally do not shake anymore unless I feel like it especially with the higher VG eliquids. I am not an exact scientific type of person and the only thing I do consistently is I always shake the bottle when I get ready to set up my tank. Sometimes even with longer steep I may not like the eliquid — sometimes I find a home for it or pour it down the sink if it is really bad. Taste is subjective so for yourself you will want to adjust the time accordingly. If you do not like it the first time, let is steep longer and see if the situation changes. Hope this helps.
BTW I lived in CHI for a number of years. Really great city that I enjoyed tremendously until the winters finally got to me. When an opportunity came up, I moved to Dallas. Now I am back in SoCal where I started from. No regrets on living in any of these cities and it was a great experience for me.
