Just got this report from United Utilities, we get our water from Haweswater Reservoir, just need to work out how to interpret it! Checking out the beginners guide, could be a long evening, pouring beer shortly!

Not sutre you'll get far with that mate - is that all they've got? No mention of sulphates, chlorides, alkalinity
The summary was enough for me ..... @Horners ... I've just looked at the full report version after your post.....
sorry, chemistry was never a strong point ....

My current method, brew beer, bottle beer, taste beer, beer good .... carry on brewing, not failed me yet in nigh on 50 years ! I was honestly interested in seeing if I needed any water treatment for brewing, but think I'll just keep to my old method!

Already been reading through the posts by @strange-steve .... going to have another go at them tomorrow !

Edited bit ..... Next morning .... have had another read through the posts by @strange-steve - not as scary as first seemed!
Our water quality seems pretty good, just need to make a few notes and see where I get to.

Hi thats what I found. I saw the size of the thread and prepared myself for a long read but was surprised to find it wasn't as feared.

At the end of the day you've been brewing perfectly drinkable beer with the water you have so anything you do to improve can only be a plus :cool:

I made my first adjustment to my last brew. Campden tablet and I used some CRS (AMS) to reduce my alkalinity from 228 to 20ppm

What size are the tablets? Mine are about 5mm or so across and the tub takes as much space as a matchbox..
I don't have any tablets. Prefer to just use up what I've got. I had a tub of the metabisulphite left over from something else so I'm just using it up. It's going to take a while lol. I'm measuring out salts anyway at that point so I doubt it's any more hassle than splitting a tablet.

Anyway, a bit more on topic, that's an incredibly soft water profile! I thought mine was soft but, wow! Baz Chaz, you are a lucky brewer.Sounds like whatever you are doing is working fine.

I can tell you from my own experience that if you try kveik yeast in a lower ABV brew (by Norwegian standards, so >8%) you'll find it drops the pH more than you'd expect and thins the beer out big time if you don't have enough salts in the wort to buffer it. Keeping the calcium concentration at 100-200ppm is doing the trick for me so far.
