Yeah, I suggest you do as JAB recommends and try distilled water.
I cannot answer for home made silver or products other than Utopia Silver as to taste, but their silver has just the faintest of metallic tastes and reminds me very much of the well water we used to draw up in a bucket from deep in the well and then drink out of a tin cup or ladle.
Of course, that was back when I was young and before dirt was invented.
