hi
after greeting
I have 4L of PG I use 1L without any problem for mix ejuice ( always I make PG/VG 30/70 at 1mg nic )
now all my juice has bitter taste , flavors is good , but after vape for 10 min I feel bitter taste in my mouth , I try vape only VG on new wick , it is sweet and no bitter taste , then I vape only PG , the bottle of PG has strong smell and taste is crazy bitter , when I open new 1L PG bottle the smell not strong , so is my PG gone BAD ?! how can I storage PG , our country very hot maybe room temp. is 37 when I go out home … can I storage it in freezer ?! like PG Nicotine ?!
please advice me ! my last 500ml diy juice is very bitter but flavor good while vaping …
Update : 20/09/2017
now I know what is my problem , I dont like to add Artificial sugar in my life , when I started on Vape before 8 month , always I try to avoid sweetener on ejuice like in my coffee , food and juice .
but now I know it is the reason , now I am using sweetener ( TPA ) on 0.75% or 1% , no any bitter taste .
thanks for all and sorry for disturb …
In that case there is something wrong with your PG and i would not use that bottle anymore.
Try the other bottles you have to see if they are the same. If they are i would perhaps talk to the vendor you got it from and complain and try to make them send new bottles to you or get a refund.
By the way, if people talk about “room temperature”, they don’t mean the temperature of your room. It’s supposed to be somewhere between 20-25°C.
I’m not a chemist, but I can only assume temperature has something to do with it. If I were you, I’d store everything in a fridge with those temperatures.
However, I’m not familiar with a bitter taste. It could as well be a contamination.
Your flavors are usually PG based as well. Storing them in a fridge usually isn’t a good idea, but I don’t think that those high temperatures will be good for them either. If installing airconditioning is inconvenient or too expensive, you might benefit from a cooled wine rack? e.g. http://www.wineenthusiast.com/storage/
you haven’t metioned what pg you’have metioned (someone else might have tried the same and have any notes to tell you about…
make sure your coil is properly wicked and the wick is clean… (not just new… but your hands are completely clean when you’re putting it inside the coil)
make sure the RBA/RTA/RDA/RDTA you’re using is cleaned well too… (older flavors etc… from times to times leave garbage and they might change the flavor/smell)
i store my nic/vg/pg in my closet in temperature room as you can see… never had the slightest problem… i can’t think anything else to suggest or warn in general… if someone else has something to suggest even better )
so you’d say the good advice is to store flavors in a fridge?
I’ve always heard they should be kept at room temp, the cold will increase formation of crystals and separate the ingredients.
