I've not been able to find much on this-it's probably here-and it is an ingredient question. I live in a small rural town we have a water co. that does chlorinate ,alot of folks here or that visit here say that the water quality is less than favorable-I swill it down right out of the tap and think it's just fine. I do have a large commercial bullet type water filter on my fridge ice maker and can tell the difference.... I have a Pur//Waterpik faucet mounted cartridge type filter in the kitchen-the closest well water(obtainable w/out question) is about 5 miles away.Do I have to drive for my brew water or is the home filtered stuff allright to use-it'd sure be easier.Any tips/input would sure be appreciated.
