I did notice the viscosity when using the PG and VG Well I tried my first mix of Choc Mint. Ok I have not let it seep, I added a tad more of Choc Mint so about 12% and not too bad, I let the bottle sit in some warm water for a awhile, I just read that someone had done that. Why I don't know. I can just taste the mint in it. A little bit bitey on the back of the throat.
Thank you all for the help and links.
A bit too much Nic I think.
When I read the rigmarole some people go to for steeping I honestly think they must have too much time on their hands! Good luck to them though and each to their own.
As Mr. DogMan says some people use 'the hot bath' method and believe it speeds up and helps the steeping process. Personally I've never bothered and literally just mix and put the bottle in a drawer for a minimum of two weeks,shaking it daily if I remember. Some also say to leave the lid of for a period of time which seems to range. A lot seem to do this on super concentrates with an alcohol base and others seem just to do it anyway. Ultimately it's your choice but I certainly believe that leaving them alone for 2 weeks helps the flavours.
From what I've read a rule of thumb is creams, tobaccos and custards need to steep but not so much fruits. I notice that nearly all darken in colour as time progresses. I don't remember if you mentioned what your final PG/VG ratio was as PG can also increas the throat hit. For what it's worth I've settled on 50/50 and 20mg freebase. I occasionally up the freebase or alter my ratio but that seems to suit me.
