For my most recent brew, I wanted to try to use all RO water and build the appropriate water profile by adding back calcium-chloride, gypsum and Epsom. I used the water profile calculator on brewers friend to determine the needed quantities. The brew day went fine and I hit all of my numbers right on.
Two weeks later I pulled a gravity sample. After tasting the gravity sample, I was horrified to find that it had a band aid flavor. I have gotten this flavor in the past but, after reading a bit on it, I determined that it was from chlorine/ chloramines in my tap water so I started using campden tablets in the water that I used for brewing.
With this last batch, though, I did not use campden tablets because I assumed that there would not be any chlorine/ chloramine in RO water. Now I am wondering if that was the wrong assumption. Can there still be chloramines/ chlorine in RO water? Should I still use Campden tablets with RO water?
The RO water was from a Glacier water machine that is in the front of my local Publix grocery store, if that makes any difference. Also, I took a reading of the water with my TDS meter and it was reading at 10 ppm.
