Ermm. Ok. So now I know......What Next???
In a fit of total boredom this afternoon I contacted Yorkshire Water to ask about the water quality for the Cheeky Dog Brewery Company head office (my garden shed).
Suprisingly they e-mailed me back pretty quickly with a pdf report. If anyone is interested, it's here
Well, I've worked on steam boilers and water treatment, know a reasonable amount about chlorine dioxide dosing potable water for food factories, and have even been known (on occasions when the beer has run out) to drink the stuff but it occurs to me that with regards to brewing I don't know the first thing about what I should be looking for, and what (if any) corrective measures I should take
Can anyone direct me to an information resource, or give any pointers
Cheers
Ian

Brupaks have a useful page on water treatment Here
The link below will give you a good outline of what is important and what you need to know.

Looks like you have pretty soft water with low mineral content then? If you're going to treat your water in any way, then it'll just be to remove chlorine and add minerals - in DLS terms probably 1g/L would be a good starting point. By contrast on my last brew I went for ~0.5g/L for my water which is hard and has a calcium level of around 100ppm.
They said they only need to test for certain things now so they sent me an old report from a few years ago. But sadly not everything i asked for was on the report after trying three times even speaking to there chemist they still got it wrong.Graham wrote:They have a legal obligation to give you a water quality report on demand.RabMaxwell wrote:I wish scottish water was as helpful as that i tried & failed several times to get a workable report from them. I actually think they go out there way to be unhelpful.

Water supply zone
Gorsty South Z152
Click here to view the detailed report
Water source
The water supply to this area comes from the River Dee.
Water quality
The water supply to this area can vary in hardness from soft to moderately hard. The supply is low in naturally occuring fluoride and is artifically fluoridated.
Quality control
There are strict regulations to ensure that drinking water meets the standards required by European Union legislation. We monitor the quality of water as it leaves our treatment works and service reservoirs to make sure that standards are being met. We also measure the quality of water as it reaches our customers. The region we supply is divided into 261 Water Supply Zones. The water supplied to a zone is usually from one water treatment works or service reservoir. All the test results are summarised in the Drinking Water Register, which can be viewed by clicking the link above.
Analysis Typical value UK/EU limit Units
Hardness level soft
Hardness Clarkes 5.950 ° Clarke
Hardness 34 mg Ca/l
Aluminium < 18.5 200 µg Al/l
Calcium 28.2 mg Ca/l
Residual chlorine - total 0.40 mg/l
Residual chlorine - free 0.30 mg/l
Coliform bacteria 1 0 number/100ml
Colour 1.34 20 mg/l Pt/Co scale

I have received one for York today. My PH varies from 7.2 in winter to 7.5 in summer. They also sent an alkalinity tot pH4.5 mg/l CaCO3 which varies from 109.67 read in Feb 2007 to 161.07 read in April 2007
There seems to be a great deal of fluctuation in Alkalinity in the small region.
If I work on an avergae alkalinity of 130 at pH 4.5 does anyone have an idea what the alkalinity of pH 7.3 will be?

My water report went straight in the bin, It told me I had hard water... I already knew that it didn't mention many of the things I wanted to know including alkalinity, talking to a local micro brewer he said it was so variable it wouldn't be accurate.bandit1200s wrote:I have received one for York today.

IMO if you are getting the mash Ph correct you don't need any treatment. My Ph was a bit high so tried gypsum first and had good results with phosphoric acid, but found 5.2 stabliser easiest to used and gave the most consistent results.
