Interesting thread. Thanks to many for keeping it alive.
I am now considering buying some glass for longer term and bigger volume storage. The main consideration being preservation of the product inside. I'll likely get a small collection of 30ml/1oz amber bottles with regular caps. Here's my (turns out, long-winded) 2¢ on the concerns already noted:
Seems a few folks have verified problems with their older plastic containers. Either giving the liquid a taint (less than ideal taste) or rendering it useless. A few mentioned a plastic taste - an obvious container problem. Like everyone else that saw this thread, I checked my older bottles out LOL.
I am an unusual use case, sort of timely (pun intended) for this discussion. One, I have been using one vendor exclusively for about a year and a half. Two, I haven't bought any small containers (except for 10ml bottles that are used for transfer, getting tossed in about a month when the child-resistant lids strip) since about Nov 2010. Yeah, boring I am. Short version: I found my favorite and gave up on trying new stuff about that time. About every 6-8 wks I order 120ml of my fave, use it up, then toss the empty. The unloved bottles that live in my juice box are all 1.5 - 2 years old. No cloves, but there are two cinnamon bottles in there. The box itself is a small cardboard gift box. Nothing fancy. It has a slight scent to it, nothing that remarkable. It's not very carefully stored in a cool spot (room temp) and out of direct sunlight.
MWA = """ Trust me when I tell ya that 1.5-2yr old juice is no where near as good as a fresher juice and probably Bad and taste no where near good, dont vape it,,,, and storing at room temp is not as good as storing in a cool dry place, these are proven facts, with the Fridge in my opinion being even better, but this type of storing technique your using RedForman is not the best you use. How your storing and the juice going from cool in the winter to hot in the summer and changing temps for this long is not the optimum storage technique.''''
The relevant fact here is that 80% of my old stuff is in the same packaging from my "go-to" vendor. Either 3, 30, 60, or 120ml HDPE #2 (smooth, translucent clear) or 10ml PETE #1 (smooth, transparent clear). When I first ordered from them even the 10ml bottles were HDPE. I don't remember when they switched - probably around Sept '10. None of those bottles have any signs of trouble. The HDPE bottles are all smooth and have none of the rippled appearance reported by others. The PETE clear ones are not soft or show any signs of deterioration. None have any plasticky scent.
MWA = '''' The Real Relevant FACT is = Signs in many bottles will only show up under a microscope, and doing certain testing, it's not always caught by the eye. I would love to see pictures of these bottles, pics like I took earlier in this thread in a dark room with the bottles up to a light. I'm not saying there is anything wrong with them the flavors your using may not be hurting the plastic to bad, that's a possibility, but I would just like to see them if there 2yrs old and juice has been in them all this time and there is no etching at all in them or no leaching has taken place like you say. I've had first hand experience with over 2 yr old juice in plastic bottles, it would be in my trash can let alone I would NEVER vape it.,,,,,,,,Straight up Nic is a whole different story ( actually it's not all mine is in glass and in the freezer ), but mixed juice is a different animal . Let me ask you something RedForman, do you use ketchup and mustard that is 2yrs old or older ? like even if it is kept in your refrigerator would you still put this ketchup on a nice fat cheeseburger or french fries ? Foods as do liquids have a shelf life and its not because of the Nicotine in the juice it is because of the PG/VG/ and flavorings and other additives used to make e-liquid, PG I believe has a shelf life of 2yrs max, and VG I believe has a shelf life of 1.5yrs, and flavorings I think even less then PG & VG """"
Next to the little box also sits one 120ml bottle of my fave dated 6/5/12. About due to reorder that one LOL. Next to it are two partial, but big, oldies. A 120ml (about 90ml remaining) of an orange flavor from 1/4/11 and a 60ml (about 35ml remaining) of vanilla dated 12/3/10. For what it's worth, those two old liquids are nearly black in color. When new the vanilla was a clear brown and the orange.. well clear orange. Today they have the same, unblemished, non-stinky condition as the little old bottles. Oh yeah, most are high nic - 36mg with a few lesser ones sprinkled in.
MWA = """" Throw those in the trash ASAP,,, the black e-liquid is clearly BAD, or rancid at this point. If you don think so then I don't know what your thinking wanting to vape black juice. Since you stated that you don't try other juices since you've found your holy grail and only vape these juices is it possible maybe you just like these flavors so much you don't notice it compared to fresh juice ? """"
So what. Well, I recently got the urge to see what's new in hardware. I bought a couple 2Ω Vision clearomizers to try out on my eGo. Awesome improvement over my last try with CE4 cartos when they came out, but I digress. I filled one and use it with my fave. The other has had about four different oldies but goodies cycled thru it. Mostly fruit flavors. They are strong tasting and not as sweet as they were when younger. Nothing I'd toss out. Well, not yet anyway. Point is, the flavor of the vape has no hint of plastic. If the Visions hold up I will be buying more and using up some of my old juices.
MWA = """ Just because it doent have a hint of plastic doesnt mean its not in it, and again juice's do have a shelf life, 2yrs is not the shelf life to all juice, in fact none in my opinion would I ever vape thats 2yrs old, even 1.5year old juice I wont vape, especially juice that has turned black when it was clear at purchase RedForeman, 2yr old juice is BAD Juice, why would you ever want to believe this is worthy of vaping ? it's jut not. Again would you use ketchup that was this old ? """
A move to glass will be for protecting the liquid, with the amber color to hopefully shield or reduce oxidation. Not to beat a dead horse, but I'm not doing this out of fear of toxic plastic contamination. I've probably chewed on enough ball point pen caps and whatnot to make a run at some of the cancer points from 30 years of cigarette smoking. Seriously. I think a round of golf with no sunblock is probably more risky a venture than e-juice bottle contamination. I've watched Coca Cola dissolve the tarnish off a penny. I rode around in pickup trucks unrestrained as a child. Ran with scissors while at the swimming pool.
MWA = """ Sound like you live on the wild side and enjoy pushing the envelope to me

"""
MWA = "" Well, we all have choices, and choices are super,,, but to have an arsenal of 1.5-2yr old juice and be vaping it, and vaping black juice that was once clear, is not a choice many would make if you took an ECF poll, just no way is this a popular thing to be doing, I believe your earlier statement of = " I am an unusual use case, sort of timely (pun intended) for this discussion. " you sure are, as most wouldnt agree with storing there juice your way, or vaping 1.5-2yr old, and Black juice, God bless ya

"""
If one or three of those old bottles get sour before I buy glass, I'm not going to be hurt too much.
MWA = """ Really ? I would beg to differ with this statement,,, in fact I would like to ask Kurt our ECF Chemist and maybe a Dr or Three, what the cae would be if someone vaped a few bottles of BAD JUICE that was sour and just bad,,, my dime says it would make one sick as a dog with a 1000 Ticks sucking its blood on a hot summer day. """
MWA = "" how much 2yr old juice have you vaped RedForman ? and why would you ever want to even vape it being that old, if you dont think the plastic is that big of a deal do to leaching 2yr old plastic bottles, then maybe just spray paint the plastic bottles Black, or tape them with duct tape so no light can get at them, wouldnt that suffice to not let light get into the bottle ? this would maybe save you a couple of bucs too, man I have heard of cheap but this takes the cake. ""
P.S: The Jan '11 Orange Creamsicle is actually pretty tasty. I've gone thru a half a tank of it while writing this post on and off.
MWA = "" Really now, lets see, 17-18 month old juice stored in plastic HDPE bottles and its actually pretty good huh,,,, I beg to differ with this one as well. I would love to take some of that juice and also a brand new bottle of the same juice and let an ECF Vet compare the two and see which he says is actually pretty good and which he says sucks.! ""
MWA = "" There is NO WAY that 1/11 which is 17-18 month old juice is anywhere nearly as good as fresh juice, not even close,,, I beg to differ with you on your statements, not to pic a fight or anything but I'm going on 3yrs of vaping, and have tested many a juices and storing juice test, seeing there changes from clear, to steeping, to 3 months old, 6 months old, 9 months old, and older,to turning black, to going sour, your of a rare breed enjoying 17-18 month old juice RedForman, there is no doubt in my mind about this.""
