Water recipe part 2

 Corrected input data for calcium( 11 instead if 1.1 ppm)

Based on Australian sparkling ale recipe,

water requirements:

Ca ≥ 50 ppm, Mg ≤ 10 ppm, Na ≤ 10 ppm, SO4 ≈ 75 ppm, Cl ≈ 50 ppm, HCO3 ≤ 10 ppm

if no salt addition, delta is as below:

Water recipe with salts added, based on 3L mash:

Overall report:

The delta

Gypsum and calcium chloride correct calcium quite well 

This combination is not perfect, but quite close 

Slaked limeCa(OH)2熟石灰 more stable and soluble than chalk CaCO3生石灰

CaCl 苦鹵， 鹵碱，鹽丹（做豆製品用）

Conclusion:

From bruhlosophy exBeeriment, not everyone can taste the difference. So major reason seems to adjust pH for yeast to ferment.
