I'm brewing the pliny clone listed here: http://farmhousebrewingsupply.fmtemp.com/ProdImages/1Pliny%20the%20Elder%20clone%20PDF-1.pdf
(seems to be the same as the one in Zymurgy)
Anyway, after reading several posts on water profiles for this beer I've come up with this (using RO water as a base so just ignore the "existing water profile" listed):
Going up to 300 or 350 ppm sulfate scared me.
But I read that the SO4/CL ratio for this beer should be really high, like 7.
I started with Tasty's profile
and changed what I thought should change to bring sulfates down to 200 while keeping SO4/CL near 7.
Am I over thinking this? Should I just use his additions and not worry? When I first entered them the estimated mash ph was 5.1.
