I have this question How can I put minerals back into distilled or reverse osmosis water?
The trouble is I don't know who is correct. I would normally go off vote count, but no one has over 1 vote. The only real way (that I see) for me to know the correct answer is to experiment and brew different batches and see who is right. Experimenting to find the answer would take time more time then is usual for accepting an answer.
How do I select an answer in this circumstance?
