It comes in the form of a liquid mineral concentrate, designed to be diluted with distilled or deionized water.

3. Perfected Empirically

We believe the role of brewing water is to make the isolation of desirable attributes like sweetness, clarity, aromatics, texture, and aftertaste as effortless as breathing.

The mineral composition of Empirical Water is dialed in to tenths of a mg/L for marvelous brewing performance.

Both Editions have been designed with the same underlying approach and can brew both coffee and tea well.
