I had a quick question about water to use in brewing.. I am brewing with one of those simple no-boil kits, but I heard that reverse osmosis water is not a good medium for yeast to grow in since essential elements have been removed from the water.
I have a RO/DI filter I use for my reef aquarium and it yields a 0-1 PPM water (almost 100% pure H2O). Since I already have the filter, I would like to use this water in my beer brewing as well, but again, I am affraid it won't work too well with the yeast.
I heard that there might be an additive I can put in the batch that adds the essential minerals that yeast feeds on.. Does anyone know of such an additive that would work? The tap water here is pretty bad tasting, and mineral water is expensive.. I think this might be the way to go if I can get a good additive.
