May be there is some help for me out there. I have made lots and lots of test batches. Most of them bad not good. One border line. And one 15 gal batch with fairly good results. I have used all the options given for titration in the J.T. Forever. Test strips work but after introducing it to the mix I find if I need to add more solution the color will not change so I need to add strip after strip as I add the solution accuracy is probably off by the time I get done P.H. meter a good one I found to be about the same and I have used phenolphthalein and get excellent response but im no chemist can anyone tell me how much phenolphthalein to use on the test I have been using 2 drops @ 1% phenolphthalein. The instructions from J.T.F say "use 1% phenolphthalein solution (1.0w/v%). If you can please help. Thanks Derick

Now I can start using the 75+ gallons of WVO that's been sitting around my garage.
