Turn the question into a controlled engineering duty
Define mineral, alkalinity, pH, chlorine, oxygen, microbiological and sensory limits from extraction and final formula needs. The acceptance basis must resolve source and treated-water chemistry together with coffee extraction and sensory target, then assign operating limits, responsible roles and controlled records for this exact task. Control coffee material and extract specification, recipe and allergen status, physical and thermal stability, oxygen sensitivity, preservation authority, package barrier, sensory reference and intended storage. Record roast age, grind and extraction convention, useful-yield definition, filtration and hold limits, protein and emulsion risk, worst-case thermal residence, aseptic or retort boundary and standardized sensory serving so extraction and preservation changes remain traceable. Record every input with units, source, approval status, credible range and decision owner. Keep an unknown visible when it can change sizing, hygiene, packaging, automation, utilities, cost or schedule.
