Treating Water With a High Alkalinity for Brewing

(That's water to the rest of us!) Beer is about 95% water, so if you want to discuss water treatment, filtering etc this is the place to do it!

Right - just put an email request in to Thames Water asking for a total alkalinity figure rather than total hardness. I put it for the attention of 'a man in a white coat in a lab'. Lets see if a bit of humour works !

I take all your learned points about Ph meters (and thanks for them) but its become a bit of habit of mine to use one. 'Have sample jar full of liquid - stick my Ph meter in it' kind of thing. Its how I learnt to do it at a brewing course I attended so its comforting to watch the rises and falls during process that I know tell me everythings proceeding as it should - or not as the case may be :roll:

Woo ho after a couple if indignant emails to Bristol water
they came back with an appology for sending me the wrong info and supplied this.

We took 52 samples over past year. Max 182mg/l as Alkalinity as Calcium Carbonate(CaCO3); Min 133 and Average of 160mg/l.

So I must assume that 160 is my figure to work from....
Next step buy some CRS

Thanks DaaB I was wondering how to cope with the Wide range.
I think the problem is that the water is drawn from the Mendip hills which are basically large lumps of chalk. and I suppose the CaCO3 concentrarion will depend on the height of the water table at any one time.

Just bought a 60L plastic jub for a boiler, I have drill and tesco elements in my hand. The rest of the bits including CRS on order or in the corner irritating the heck out of the wife . Standby for AG#1 coming soon to a forum near you

Looking at Leyland homebrew site I see tehre are CRS and Dry Liquor Salts used to adjusts alkalinity. Are these the same as CRS or a different beast all together

Hi,
Finally got a water report that means something, Is my water ideal for brewing?

In response to your recent e-mail
Average pH = 7 pH unit based on samples taken from Ardsley water supply zone
Average total alkalinity = 160 mg/lHCO3 based on samples taken from water treatment works that supply the water supply zone
I trust this information is satisfactory.


If it's not good brewing water, any chance of a pointer in the right direction on what might need adding to make a decent bitter or pale ale.

Thanks
John

Do you recommend throwing owt else in? i.e gypsum etc :?

Thanks for the replies DaaB, the more I learn the closer I'm getting to my perfect pint.
Is it worth adding anything other than gypsum, you know, DLS or owt else that might spring to mind, or is the use of CRS and a campden tablet is all that's required for my type of water?

Would you say my alkalinity and ph is high or just normal?

I have just contacted Severn Trent by email, they replied with:

"I can confirm that the alkalinity level the above area is 1112 mg/l and the term is expressed in CaCO3."

This seems a bit high? :shock:

They also gave a link to the report they took the figure from but I can't see where the figure came from.

Exactly what I thought. I have emailed him to see what he has to say for himself.

Check this information about Burtonising water.
Very informative.

Hi All
Used CRS in my last brew and some gypsum, fantastic, never thought I'd say this, water treatment makes a really big difference!!

rang up my water provider, Bristol Water, and they got one of their lab bods to get back to me with the figures i need. Very helpful. min/242, median/248, max/259. guess i should go for the median figure.

I agree Chris, such an important topic like this was/is, shouldn't be allowed to drift down the thread to only surface from time to time :!:
