    If you look at the details tab, they say:

    "Wine packaged in this way will have a shorter shelf life than bottled wine as the bladder is not hermetically sealed."

    Define shorter shelf life?

    Keeping in mind that good wines can last decades in properly sealed bottles, shorter could mean anything from months to years.

    Hi Jeri.
    This leads me to think that even though some PE bladders are gas permeable, I would think it's a better alternative that a glass bottle that is half filled with developer. The one I'm using has a double layer of PE.

    Does this mean that analog photographers drink too much?

    The amount of oxygen in a half filled glass bottle is limited. Once it is used there is no more unless the bottle is opened again. However, oxygen is constantly passing through the polyethylene bag.

    Dektol turns brown as it gets oxidized. So does D76. I can tell when developer has been stored in half-full bottles for too long because it starts to turn brown. Developer stored in wine boxes stays crystal clear for over well over a year. That's all you need to know, IMO.
    f/22 and be there.

    Of what type of bottles are you speaking? One must also consider how well the cap excludes air. If the liner is damaged in any way the seal is compromised.

    Besides polyethylene some cubitainers use a composite material which is better at blocking oxygen. I personally avoid any polyethylene containers for developers.

    I'm not so sure keeping any kind of non-drinkable chemical in a container that is generally seen as containing a drinking substance to be a good idea. Taking the bladder out of the box and storing securely is one thing but using and keeping it inside the original wine box even if you wrote on it that it's not wine, is asking for possible trouble. Sure, sometimes chemicals come in similar such boxes and bladders but those boxes look more "clinical" in color and wording than your more festively worded and designed wine box. I know it sounds far-fetched but a drunk person finding a wine box might be so drunk as to not take care to read the outside (assuming they are not too drunk to read that is). Stranger things have happened.

    So cover the box in duct tape.
