Did not work.  I even tested it.
I tried adding this to 2 different red wines and didn't see a significant change in PH.  I tested the wine before adding the product and saw a reading of 3.74 on my PH meter.  I added 3 drops as directed and stirred for 30 seconds and got a reading of 3.85.  This is an insignificant change for those of us working to control our acid reflux.  I got very similar readings the day before with a different red wine.
