    This is an open question to anyone who might be able to shed some light on why this works.

    For those that may be reading this, and are not familiar with the term; seed steeping is the practice of adding a fresh batch (of the same recipe) to approximately 10-15% of a previously fully steeped batch with the apparent benefit of accelerated steeping of the new mix.

    In @dannyv45 's blog; he gives an example, from personal experience, that reduces a particular recipe from a normal 5 weeks required steeping to a mere 2-3 days:
    Everything you wanted to know about steeping and then some. | E-Cigarette Forum

    Danny is not alone in finding benefit from this technique. I have seen multiple DIYers, on multiple forums, who have also recommended it.

    My inquiry is why does this work? I am NOT trying to debate whether it works (and I don't desire this thread to turn in to that). I am more interested in what chemical/physical process(es) is/are happening that makes this work. I understand the biological benefit in a brewing application (particularly with yeast propagation) but, for the life of me, I don't understand how this accelerates a bonding and blending process.

    Can anyone help me understand what is happening?

    Secondarily, and perhaps it will be answered by the primary question, why does this seem to work better for some recipes than others (those that require extended steeping. I think it is fairly obvious that shake-n-vapes, and those requiring only a few days, will gain little/no benefit)?

    I just do it so I don't run out, though, it seems like a good idea.

    I just heard of the term after I've been doing it, so that's a plus.

    Interesting. I will have to try 10% of 30ml would be 3ml of juice..

    Still hoping someone can explain this to me (what is happening and WHY it works?).

    I know it works and don't know why either. What I have found is that if you keep doing it in the same bottle multiple times, and this includes just reusing a bottle that's mostly empty except for residue, after awhile it actually becomes unpleasant. Can't describe exactly what kind of unpleasant, but it's along the lines of metallic, like when you use too much of a highly concentrated flavoring like SC/Flavora.

    Really, it might just be my imagination, but I wash my bottles after three remixes.

    What happens when you introduce entropy into an ordered system?

    By the laws of thermodynamics, it accelerates the deterioration of surrounding particles :) Thus, the reason seed steeping/aging works so well.

    Maybe the plastic is deteriorating.

    I gave up using plastic long ago and only use glass even for the 3ML bottle I take along for an emergency refill!

    Thank you @Hoosier & @ceeceeisme
    That's finally an explanation I can kinda/sorta understand (high school physics was several decades ago!). :thumb:
