Porter Water Profile

[dlowe1992]

Evening all,

I’m brewing a porter this week, which is a step into the unknown for me, so after a bit of water advice. All previous brews have been golden ales / pales of some variety or bitters. My water here (Severn Trent, Shropshire) is high in carbonates and so I’m used to having to reduce this a fair bit with CRS and address the Cl/so4 balance for hoppier beers…

I’ve had a look at a few darker water profiles and seems my tap water is fairly well suited?
The below figures are a best estimation of my base tap water…

Ca 104
Mg 7
Na 17
Cl 53
SO4 29
HCO3 189

Would I be along the right lines if I balanced the Cl / so4 out and kept the carbonates as is?

Ta,
Dan

Use some software like Brewers Friend or whatever you use now. If you do not have one use any of the software available enter your water profile, enter your target water profile. London profile if using Brewers Friend. Add your grain bill as this will have a buffering effect on the water profile due to the minerals in the grain.
The Delta will give you the additions needed to achieve your mash pH according to your water profile and the grain bill.
