[MODNOTE: This post was moved top this forum for reasons expressed in post #9 below.]Hi guys,
I'm planning to do my first AG and first BIAB brew at the weekend and am wondering whether I need to do any water additions (salt/acids etc.)? I brew with rainwater from our tank at home in Perth, WA and am planning on making a London style porter, so there is a bit of chocolate/crystal malt and roasted barley in the grain bill. I've read that rainwater is effectively a blank slate for mineral salts etc. and this affects the enzyme activity and taste to a certain extent, but given this is my first BIAB I'd like to keep it as simple as possible so if I am able to brew a reasonable beer without getting into the water chemistry stuff just yet then that would be ideal!
Another option would be to replace some/all of the rainwater with tap water, since this would at least have some salts in it, although I don't know what the Perth water profile is like?
Any help would be greatly appreciated!
