Brew parameters

Water GH

Also known as GH · general hardness · dureza general · Ca+Mg

GH: General hardness · dureza general del agua

What it is and what sets it apart: GH as ppm CaCO₃ or °dH—not KH and not pH. Ca and Mg can taste differently.

How it’s used or measured: Measure with a GH kit. Build water recipes splitting GH and KH salts. Log both in Brew Lab.

Flavours and cup impact: Moderate GH: more body/sweetness; very low: thin; very high: heavy and scale.

Technical notes: With KH it defines the mineral profile.

Common mistakes: Tracking only GH. Confusing GH with conductivity. Remineralizing blindly.
