    PG and VG do not decay. Nicotine does though. It is susceptible to heat and light. Ejuice kept in a freezer though can last a very long time.

    It is unsurprising you experienced flavor changes. You diluted the juice. Also VG tends to have a muting affect on flavors. High VG juices generally have flavor profiles adjusted to account for the changes made by VG

    Depends on the environment you keep the mix in and the susceptibility of the chemicals to standard temperature and temperature (STP). I would think storing the mix in a refrigerator in a sealed oxygen free light proof container at a constant temperature would pretty much maximize your storage lifetime. As to how long it would last is anyone's guess.

    cause i just purchase 1000ml VG n 500 ml PG, so should be almost perfect for 70/30, plan to mix it up, than play with flavor and nicotine later ...

    Might try mixing only a small batch to last 2 to 4 weeks before mixing it all to begin with. My tastes rapidly changed when I first started vaping. You can always add nic at a latter date to *any ratio of PG/VG mix, here again, might be wise to mix small manageable nic batches.
    *Nic is also cut/base with different PG/VG ratios, so your initial nic ratios may change very slightly.

    I would think you would be all right mixed for a year or so. I have a gallon of VG stored in a cool dark place that does not vary more than 40 F. for 3 years and still tastes fine, as for PG, I don't know how stable that is. The VG has been only opened 3 or 4 times to take a few pints out and transferred to a smaller container.

    A mixture, of ONLY PG and VG, should be extremely stable (PG is naturally antimicrobial; and neither are susceptible to oxidation). Just keep the majority of it, in a cool dark place, and I would expect it to easily last for a year or more. I could even see it lasting for multiple years.

    I have (separate) gallons of PG and VG, that are going on four years old, and I can not detect any change in either.

    Agreed. I'm using my VG and PG that are at least 2 years old, if not older, no change whatsover. Kept in a dark closet in dark bottles, never refrigerated or frozen.

    Nicotine and flavors and other additives do deteriorate with time, though.

    Mine aren't even in dark bottles. They have remained in the HDPE (translucent) one gallon jugs they shipped in.:) I imagine the dark closet reduces/removes the need for light blocking containers.
    Yep; I completely agree.:thumb::D
