Reply To: What is your favorite brand of instant coffee?

I am too female to remember all the details but I DID ask and was told that coffee through a filter is NOT borer. The only thing I remember is that the water goes in and comes out after passing thru the coffee. They were never considered a mixture. If you had grounds boiling in a pot of water and THEN passed it thru a melita, THAT would be a problem. (and btw, I asked a posek, not someones brother-in-law). The kli revii is necessary for the bishul aspect.
