    Definition

    Water pH is a useful context value, but it is usually less explanatory than hardness and alkalinity for actual brew behavior.

    Why It Matters

    pH can still indicate extreme water conditions or recipe mistakes, especially when building custom waters.

    Avoid
    • Do not optimize pH alone without understanding buffer capacity.
    Page Context
