We just installed a reverse osmosis (RO) filter system at our house, because the tap water tastes gross. I tested the TDS and it was 3ppm! I thought “oh that must be great, pure water,” but my friend told me you actually want minerals in there to help extract.

So… Anyone else in this boat? I know there are RO systems that will remineralize after the filter, but ours doesn’t… And I don’t think I want to uninstall this beast. I know there are little drops you can add, but they seem expensive… Just wondering what y’all other home brewers do. Thanks!

    Excellent, thank you! I didn’t think it’d be similar for beer, but makes sense.

      Yeah, here’s a bit of a guide from the beer side and a little extract.

      The more chloride, the more malt flavors shine. Enhances fullness and malt sweetness (thick mouthfeel). The more sulfate, the more hops bitterness shines. Produces a drier or crispier beer (thin mouthfeel). Link
