This is the date. I s/w Rich Stark co-owner of ESV http://www.esvco.com/ BEFORE I posted this thread and he stated there are no expiration date on this product. He also stated if the Alkalinity part form solid on the bottom of the bottle, to just warm the contain in warm water. This is normal if stored on a cold floor. The bottles has been in my warm finish basement. I have not open any of the bottles to see if this happens. I purchase this approx. one year ago from a LFS.
