Calcium In Apple Juice

[UpstateMike]

My "go to" juice used to be one where the only ingredients are Apple Juice and Malic Acid. That was it. Unfortunately, that juice is now $5.49 a gallon.

They also have another juice that has the following ingredients:
Filtered water, apple juice concentrate, calcium gluconate, calcium lactate, ascorbic acid, malic acid.

That juice is $2.89 per gallon, slightly more than half the cost of the other juice.

So has anyone fermented with calcium in the juice before? I'm not sure that it is really a big deal, but was hoping to get opinions on taste.

i guess no problems for taste http://www4.agr.gc.ca/abstract-resume/abstract-resume.htm?lang=eng&id=15142000000228

and wiki says Gluconic acid occurs naturally in fruit, honey, kombucha tea, and wine

After some quick research it's an economical solution for fortifying high brix drinks (sweet) because it is a very soluble white powder. Apparently it's colorless and "practically" flavorless.

I'd try a small test batch before making 10 gallons, but you should be fine.
