Anyone mineralize water for brewing? (lemmy.world)

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!

Yes!

I based my recipe on WOC Budapest from Barista Hustle: https://www.baristahustle.com/blog/diy-water-recipes-the-world-in-two-bottles/

33,75g Sodium Bicarbonate, 62,85g Epsom salts, Dissolve in enough distilled water to make 1000ml of concentrate

Add 10ml of this concentrate to 5l of RO or distilled water.

Boom. Perfect water for brewing.

Dang, my inner coffee nerd is tingling at trying all the recipes. Thanks for this! And it looks super cheap.

Just curious, do you remineralize for drinking water too, or just making coffee?

It is super cheap 🤣

Only for coffee. Our tap water is hard af and destroys any machine it comes in contact with, but actually tastes OK most of the time.
