Target Water Profile

Iceland - avarage

Ca⁺²	Mg⁺²	Na⁺	Cl^-	SO₄^-2	HCO₃^-
75	20	25	50	200	50
Palmer: For red IPA, the water profile should be something like 75 ppm calcium, 20 ppm magnesium, 50 ppm bicarbonate, 200 ppm sulphate, 50 ppm chloride and 25 ppm sodium with a residual alkalinity near zero, which, with these numbers, works out to about (-)5.

Notes

The plan was to use Imperial A10 Darkness but brew.is was out of stock. Wyeast 1007 (German Ale) or 1084 (Irish Ale) would be options but we don't have them so we could use S-04 or the expired Kölsch yeast that we have. Just use a lot of it.
