Well, the setting at the moment is such that I work on a small batch trial c/o a co-packer that has all the facilities needed but he does not produce his own treated water.
Being a small batch of some 100 gallon or less to be diluted, the solution is to purchase and use bulk, commercially available treated water.
Given Silk City's claim that such water is "not been treated with any kind of antimicrobial - chlorine, bromine, etc - and could contain some kind of hazardous nasty... Algae loves this stuff"--the question remains ( whether such contamination is realistic or just hypothetical) as to whether or not such (in all likelihood-) minute contamination will or will not be 'taken care of' by the, say, 40% alcohol content in the product... I am sure some small and/or experimental batch producers face a similar issue...
