You can continuously create mothered ACV. It may not always be organic, but it's the mother that really counts.
1) Find some mother somewhere - either buy a small bottle that has it already formed, or borrow a big glob of mother from someone.
2) Buy as large a jug of regular ACV as you can find, and put the borrowed mother into it.
3) Let it sit, and sit, and sit. Shake it periodically.
4) Once it has clearly formed a good amount of mother you can use a cup or so to inoculate jug after jug of regular ACV.
Make sure to get a bit of the mother each time you pour some from your base bottle into a new un-inoculated bottle of ACV, but never use up all the mother in the base bottle.
As the liquid in your base bottle gets low, pour some more regular ACV into it and repeat.
