Hello All; I am wondering if anyone out there uses Reverse Osmosis water for their coffee brewing. While visiting our host's site I read they recommend spring water because it has the natural minerals but not chlorine. I have been using water softener water which SM says can dull the brew. I bought a gallon of spring water and tried it. It did make a great cup. I had been considering a RO unit for the kitchen sink because of the increased sodium in the water softener water but, if RO water produces a dull brew, I would prefer to just stick with the whole house filter with carbon to remove sediment and chlorine. I can bypass the softener to supply the kitchen sink. Any input about what kind of water you all use would be appreciated. Thanks, Gary Raabe Cincinnati OH Introducing Live Search cashback .
