A guy I work with makes very good beer using RO water and adding nothing. It is labeled as drinking water, but I guess he didn't know it went through RO. His porter is one of the best I've ever had. Very surprised. We are starting to talk about water chem. I'd like to see how his beers taste with minerals added.

I've recently brewed a few batches around 90% RO water and the rest tap. We'll see how they turn out. Tap water alone with my light colored beers produces metallic off flavors.

Unfortunatley this is not so. R/O units work on a percentage of capability. My R/O unit runs aat 98.9% effecient. My tap water reads 264ppm before filtering, so it should read 2.9ppm after (its actually 4ppm).

So, if I was in Pheonix where the water is 1500ppm (WTF) it will come out at 16.5ppm.

The only trouble with R/O units are that they do strip everything out of the water including trace elements. These trace elements, wnich are impossible to replace, are what give different water its taste. eg. Burton-upon-Trent, England.

If you just want to remove the fhlorides and cholrides it is very cheap and easy to set up a activated carbon filter.

Ok, so I have lots of Culligan bottled water.

the report on it can be found here
Culligan waer report

but it does notlist some of the items asked for on EZ water spred sheet.

If someone cold look at the report and give the base values, it might be a good plce for Culligan users to start.
