I haven't brewed it yet, but I have a recipe in the works for a white IPA (Chainbreaker clone) and went with Bru'n Water's 'Yellow Bitter' profile, and am letting the RA go pretty low... lower than the spec'd profile at least. I have the calculated values here so far:
Calcium 53.7 ppm
Magnesium 11.1
Sodium 6
Sulfate 102.6
Chloride 47.8
Bicarbonate -82.7 (zero in reality)
RA -113
Hardness 180
SO:Cl ratio 2.1
It's a White IPA, but it's still an IPA. Give the hops what they deserve!
