Of course you can brew with RO water.. its complete BS that you cantmickiboi said:So now to my question. I have been told I cant brew in distilled water and I have been told that's BS. Apparently all I need to do is to add calcium sulfate to the water (0.5mg/l) to use with a kit and I have been told I don't need to do anything. What's correct here? If I do need to do something to the distilled water in order to use it, what do I do? I sort of need to work this out now as everything I will do will be done with distilled water.
Thanks in advance
There are already trace elements and minerals in the malt extract which the yeast needs
The matter of water chemistry comes down more to the style of beer you want to brew.
English ales are historically made from harder water. Google Burton-on-trent water and burtonizing water ( epsom salts, gypsum etc )
Pilsners are made from soft water ( more like rain water )
My suggestion would be to brew with rain water if you can get it or whatever water doesnt cause you problems
Brewed for AG many years just using rain water and my beer was always fine and I never added anything to it, except a few experiments with English Ales and salts which really did make a difference with respect that it gave the beers a real mineral bite
