Anyone mineralize water for brewing? (self.coffee)

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!

Remineralize, buy bottled water, or possibly reduce your brew temp to try to counter the aggressive dissolving power it has. Could also buy a pitcher filter and fill it with tap, and use that for coffee.

RO is pretty bad though.

That's interesting about water temp.. I didn't realize it was a matter of cleaner water extracting more. Do you mean RO is bad overall, or just for coffee?

Just for coffee.
