VG flavor over time

[P-Funk]

I have found that the flavor of my stored VG juices has changed over time. It has become noticeably weak after a week of storage.

What can be done to counteract or prevent this?

DIY and vape it, and dont make so much at a time

I agree that the flavor changes, but I don't feel that it gets weaker in particular. I think it just gets smoother and more even. I have an unproven theory that flavors in VG mixtures float, don't diffuse very well even if shaken/stirred, or have a lot of hot spots. When you buy from a supplier, the juice is usually already a few days old and the flavor has had time to become homogeneous. When you mix it yourself, sometimes people report getting no flavor even when upping from 10% to 20% to 30% etc, while others report a strong flavor at 5%. For this reason, I like to give my flavors 1 day to settle before really judging it, and it's often very different than 1 hour after I mixed it. Then again, I could be totally wrong.

Thanks for that advice PureVapor, I like mixing 70/30 vg to pg. I mixed some juice yesterday this way and tried it out and it does seem to have a bit more flavor to it today, you may be on to something here.

My unproven theory is that VG temporarily "encapsulates" the flavors, walling them off from the taste buds until the flavors are thoroughly diffused, molecule by molecule. I've shaken VG mixtures until my arm was tired and it seemed to make no difference. Even though the flavoring must have been thoroughly dispersed, its taste was weak until some time had passed.

I've noticed that mixes with flavorings such as clove and cinnamon may gain flavor strength for as much as two weeks after mixing.

Next experiment: divide a VG-based mix and place a bottle containing half of it in an ultrasonic cleaner filled with hot water. Run the cleaner for an hour or more to agitate the mixture, then compare the two samples for taste.
