Hi fellow brewers,
I used 100% reverse osmosis water on my first brew. Do you think there is anything wrong with just using softened water instead. The reason I ask is the RO system only stores about 3 gallons so I have to plan ahead.
I spent two years using the water from the RO system. Everything was good! However, now it seems to me that in beer there is some unpleasant flavor. I walked away from this water. I think to ordinary drinking water it is best. Disinfecting filter UV, for reliability.
Generally you need to drink a glass of water, for example. If you like the taste water , then and like taste beer. This is my opinion.
Sorry for my english.
In my younger days I looked after a water treatment system in a large steam generation power station which had a big reverse osmosis plant which is really an extreme water filter.
Very high pressure water is forced through a membrane filter and only water molecules are small enough to fit through the filter.
It was explained to us that….imagine a water molecule is the size of a ping pong ball….then a bacteria molecule would be the size of a basketball….so only pure water molecules manage to pass through the membrane filter…unfortunately/fortunately all other particles are too large to fit through….which includes any minerals etc.
So once again you need to look at RO system/water as a really extreme water filter….that removes all the “bad” stuff as well all the so called “good” stuff….minerals etc.
Phew! I started reading this thread and started to think I was really going to need more gear. Our QLD water is pretty hard and the coffee machine needs regular descaling but I hadn’t had any problem so far with the WW (20-ish brews in the last 15 months). I’ll keep using the tap water 😀
