Tap water (sterile) dilution/'high gravity brewing

[p4ddi]

Hello,

I’m fairly new to home-brewing. I’ve tried a couple of extract recipes and one all-grain mash.

All has gone okay so far, though one batch got left in the fermenter for too long, and was probably better for pouring on chips rather than down the hatch.

My set-up is one burco boiler, with an inverted stainless steel colander for grain mashes, which is retained nicely when the immersion coil is resting on it. I’m using a standard plastic fermenter (without airlock), then bottling it in 500ml Grolsh style amber swing top bottles (750ml seems like they’d be less faff).

The last extract mash I tried, I boiled with hops in the usual way. I then transferred it to the fermenter and cooled it. I then diluted it using tap-water to 1.040 gravity.

My question was whether I should be worried about using tap water (as I’ve not sterilised it).

The second question is whether or not I can transfer this “high gravity” brewing technique to all grain brewing? If I brew 10L and dilute to 20L (whilst still maintaining a reasonable extract) am I going to affect the flavour.

Comments appreciated…will try and let you know how I get on.

Thanks!

Get a couple of demijohns and steralise them, cap them and put them to one side. Now boil up 10 gallons of water, let it cool and pour into demijohns. I didnt cool once and broke my glass, so make sure it IS cool. Leave water to climatise in brew room. You now have 2 gallons of diluting water ready to use. You are 100% sterile and have removed the temporary hardness. Simples!

As for all grain. They say the dark side calls when the time is right.

Thanks for that.
Common sense, really.

Do you think I'll have any issues having used tap water?

No problem... but treat it with C tablet no need to boil..
