Find Water for Coffee Brewing by TDS

Why TDS (PPM) Matters: Best Water for Coffee Brewing

Choosing the right water is essential for brewing outstanding coffee. The Total Dissolved Solids (TDS), measured in parts per million (PPM), directly affects extraction, flavor clarity, and balance in your cup. Our Find Water tool above helps you discover the best water for coffee by TDS (PPM), tailored to your country and taste preferences.

What is the ideal TDS for coffee water?

Most coffee professionals recommend brewing with water that has a TDS between 75 and 250 PPM, with 120-150 PPM often considered ideal. This range provides enough minerals to extract the coffee’s full flavor without overpowering or muting its unique notes.

What is the TDS ratio for coffee?

The TDS ratio describes the concentration of minerals in your brewing water. For most brewing methods, a TDS of 120-150 PPM is optimal, but experimenting within the recommended range can help you find your personal sweet spot.

Is 25 TDS safe for RO water?

Reverse osmosis (RO) water often has a very low TDS, sometimes as low as 25 PPM. While safe to drink, water with such low mineral content is not ideal for coffee brewing – it can lead to flat, under-extracted coffee. For best results, remineralize RO water to reach the recommended TDS range.

What is TDS of coffee?

TDS in coffee can refer to the dissolved solids in the final brewed cup (usually 1.2–1.5% for filter coffee), but when selecting water, we focus on the TDS of the water itself. The right water TDS ensures proper extraction and brings out the best in your beans.
