Is regular, kedem grape juice (plastics bottles) ok? I called the company and was told that they don’t add any sugar. I saw that in the past, you recommended only using the ones in the glass bottles, is that still the case? Thank you
If they confirm that there are no added sugars or unlisted additional ingredients (as this implies there are extra steps in the concentrate preparation) then it's okay. That being said, it's been reported that their "Organic Grape Juice" is a lot milder on the stomach.
