I was interested in freezing as well. I'm curious to know how much expansion of the flavorless you experienced when you froze the stuff? Did you do anything special to prepare it before freezing?
I am currently using eliq (10/13/2009) that has been in freezer about 2.5 years; it is still perfect.
Clear and strong with clean taste.
I vape at 12mg which gives firm TH.
I have not noticed any expansion issues; I have some is in glass bottles with a small amount of air.
Juice in plastic bottles is placed in freezer with no air cap; I squeeze air out so there is room for unlikely expansion.
I put juice bottles in freezer bag then placed into igloo cooler then placed in 5F freezer.
Frozen meat develops freezer burn in less than 2 years but my 2.5 year old eliq has no freezer burn.
