Best filter for coffee shop with hard well water
I operate two coffee shops, and at one of my locations, I can't seem to get the water right. The company who own the coffee equipment have installed a Pentek GS-10ALS inline on the coffee equipment, and the coffee still tasted bad. I since put a Filtrete system in. It's better, but it's not right. There is also a master sediment filter from the well.
We had the well tested by a lab:
Hardness - 82 PPM
pH - 7.3
Iron / Manganese / Nitrite - None detected
Sodium - 5.4
Sulfate - 25
Nitrate - 1.7 PPM
Somebody told me I need to soften the water.... then I also read somewhere else that if the water is softened, the coffee doesn't extract well when brewed.
Any advice on what might be the best solution? I'm looking for something I can put inline just on the coffee equipment, because the well services 4 buildings and I don't want to pay to improve their water!
Thanks in advance!
