TDS, or Total Dissolved Solids, is a measurement of the amount of "stuff" that has dissolved in your water. This is measured in Parts Per Million, or ppm. For each Third Wave Water Profile, this number can vary because different profiles have different needs for their quantity of minerals. Each of the below measurements could see variations of +/- 10%.

TDS by Profile:

Classic Light Roast Profile has a TDS of ≈150ppm

Medium Roast Profile has a TDS of ≈150ppm

Dark Roast Profile has a TDS of ≈180ppm

Espresso Machine Profile has a TDS of ≈150ppm

Low Acid Profile has a TDS of ≈220ppm

Cold Brew Profile has a TDS of ≈220ppm
