Water

For buying filtered or mineral water in Brighton please see supplies page.

So this is a rough approximation of Brighton brewing water treatment from a sample taken around a year ago so even if you had the same water source as where this sample was taken from it may very well have changed since then.

Results have been taken from two sources. My water (with a house water filter) done in Jan 2015 and Richard from the Brewclub done in 2014. We’re both based in Brighton so you should get a rough idea of the water. If you’re looking for a more accurate measurement I’d highly recommend Murphy and Sons’ treatment – lab manager Paul Taylor is a keen homebrewer and a very helpful, nice chap to boot.

Under each table, you’ll see some information about how to treat the water. Please note, Richard’s has slightly different treatments as he has opted for the DWB treatment which is specially prepared CaCl/CaSO4 mix.

Most homebrew software has some basic water treatment calculator functionality but I’ve found those and others online a little lacking in some areas. Recently I’ve tried out Bru’n Water which seems extremely in depth and also has some useful pointers as to why you should have this particular ion and how much of it. Give it a go if you want to go into more depth.
