What is the consensus on using tap water (without boiling - i.e. straight from the tap) to top up partial boil worts?
I'm having my second ever brew day this weekend, 2 weeks ago we followed John Palmer's instructions on How to Brew for partial boils, and boiled the water we were going to use to top up first. We didn't try and cool this down in anyway (other than leaving it for 2 hours) so when we came to add the wort to it, it was still way over pitching temperatures and we had to mix in some tap water as a last minute fix.
Afterwards I read that some people just use tap water anyway, are we doing extra work we don't need to?
