Boy, you sure know how to put the pressure on! This
is likely the topic you are thinking of, but I think it may not include the specific info you seek.
I think that Wyardley's LA TeaAffair buddy, Danica, was routinely remineralizing either distilled or RO water with a product made specifically for that purpose. You could PM Will to see if he knows the name of it if you are interested. If he doesn't, I have Danica's email address from some oolong help she gave me a couple years ago. I could send her a note.
