Is distilled water acceptable for making coffee? At my work we have a distilled water cooler or tap water and I can never make good coffee at work. I'm grinding fresh beans and using a Melitta BCM-4 but the coffee always has an odd taste. I've used the same brewer at home with the same beans and made great coffee so I'm now thinking its the water. If you agree then what bottled water would you suggest I use?

According to the SCAA, distilled water will not taste good for coffee. This post on H-B covers that recent publication. As for the preferred bottled water, it will likely be regional. You might pick up a TDS meter, and test some of your regional bottled waters to see if you can find one that measures around 150 mg/l. This one at Amazon is $21 shipped, and gets good reviews. Also pick up some calibration solution. This eBay Seller sells that meter with a pack of calibration solution for $17 shipped.

You could try running tap water through a Brita.

distilled water cooler ????

I hope you are not drinking it.
I believe that if you dig further, you will find that the long term consumption of distilled water can be hazardous to your health............something about leaching vital minerals from your body.

Wow I didn't know that about distiller water I'll have to look into it thanks. Today I brought in Ozarka water for my coffee and it was great! I'll have to get a meter and do comparisons of the bottled water available locally. And if the distilled water is bad for you maybe I can get the company to switch back to Ozarka problem solved!!!

Just make sure you are doing the reading at room temps; both water and coffee or your readings will be way, way off.  I have found (just an early observation) that the higher the TDS of the water, the less propotionately the coffee solids will increase once the coffee is brewed.  Harder water => less coffee solids in the cup.  Early observation only.

ok I asked a similar question elsewhere but probably should have posted it here.

We have filtered water, by way of reverse osmosis. I understand that it is makes for a very pure type of water. Is this the wrong kind of water to make coffee with?

Both distilled and reverse osmosis water are not suitable for coffee. The lack of ions makes coffee fiber swell and impedes water flow. For this reason, extraction will be unnecessarily prolonged (for the same grind particle size) and coffee will taste bitter.

For similar reason, ion exchanged soft water, replacing calcium with sodium, will also swell the coffee fiber, even if TDS can be similar.

TDS meter readings should be done at manufacturer's recommended temperature. Room temperature is generally acceptable. When the reading is taken at higher temperature, the value is adjusted with software and not true TDS. For the inexpensive price, it is not a bad deal, consider human ability to distinguish minute different TDS is the limiting factor.

If one must use distilled water, consider buying reagent grade electrolytes from chemistry supply manufacturer, jewelry's scale, and TDS meter to make "ideal" coffee water.

Ok so now I am concearned. We  are on well that test clean and good every year but we dont drink that water because it is hard and has its own taste. So we have been drinking "distilled water with minerals added" for years. It taste great and when I check it with a hardness strip it tints the strip just little bit but its enough to register on the strip. Thoughts on that kind of water? If you have to build your own water were "reagent grade electrolytes from chemistry supply manufacturer, jewelry's scale, and TDS meter to make ideal coffee water" how would you go about it and were is the proportions etc?

THanks

 
Yes i have a reason for leaving SCG off my list, yes it is my opinion, yes it is subjective as opinions are by definition, no don't start a flame war because you disagree.
