I got some vg from bull city and it was dope vg, thick, clean, oderless. I made 3 beta mixes all in 30ml and after a week lf steeping they smelled horrible, they were all max vg but looked like like max pg, and then I looked at the vg and that also became watery.
VG tends to thin out if it's heated a bit. I know the VG I keep in my room is a little thinner since my room is always warm.
Would you recommend keeping vg in a cool place like with the nic in a mini fridge near your work area ?
I've never had any issues with my VG by not storing it in a cool, dark area so I really don't know. I go through a liter of VG in about 2-3 weeks so I've never had it long enough to notice any quality degradations. If you buy in bulk though to the point where it can take you quite a while to go through all of it then it may be a good idea to store it in a fridge.
