Hope Valley reservoir water profile
« on: July 06, 2013, 03:33:26 PM »
Has anyone got a water profile for Hope Valley that they can post?

I'm buggered if I can find anything useful on the interweb.  The only data SA Water seems to have is more to do with water quality.

Cheers
Jules

Any idea which water system Magill falls into?

Hope Valley is North East so geographically close but since all the work with desalination etc. I'm not sure what that means. They've been building a ring main connecting the various reservoirs to enable the desal water to be shandied in with all the rest so I'm not sure where that leaves us with this data. Certainly better than nothing though and I would think desal percentage in the mix will be minimal at this stage.

It was my understanding that the desal plant was pretty well shut down at the moment.  I may be wrong though...

SA water site says desal plant has delivered 3billion litres in June.

Not too sure if it made its way up to us though.

Burnside water has recently turned into shit. Not sure about the desal contribution, but the chlorine went through thee roof. Yuck.

Ok, so I'm off the little para system. Any ideas on what this means I should so for water treatment?  I get my brew water through a pura tap filter. I vaguely remember dan saying he adds a teaspoon of X for dark beers and a teaspoon of Y for pale.

I've done some calcs for little para but I'm away from my pc this week.
The main problem is the high Cl :(

I'll post what I've got when I can, I might have some notes on my dropbox somewhere...

Local filtered water little para (average)
Calcium 26ppm
Magnesium 17ppm
Sodium 73ppm
Sulphate 49ppm
Chloride 123ppm
Bicarbonate 84
pH 7.4
Add 1.5mL 85%Phos to bring Sparge water to 5.5pH

Salts

Mashwater adjustment
2.8grams Gypsum CaSO4
1.4grams EpsomSalt MgSO4

Spargewater adjustment
2.1grams Gypsum CaSO4
1.1grams EpsomSalt MgSO4

Final water
Calcium 50ppm
Magnesium 22ppm
Sodium 73ppm
Sulphate 125ppm
Chloride 120ppm
Bicarbonate 85ppm

That's what I add when I adjust my water, usually I brew a recipe that suits the water rather than change the water.

I generally use a 7kg grainbill 28L mash and 21L sparge, to give 21L of primary gyle and 21L of secondary.

Can you elaborate on this some more?

What would be involved in getting the analysis done on the water privately?

The Problem is that is changes... often.
Our water is not consistent, for the most part. So if you get your analysis done, by the time you get the results, it'll be inaccurate.

My understanding from a mate who works for SA Water is that the Desalination plant pumps water to Happy Valley and chandies it in with the exsisting catchment water (which is also fed from Mt Bold, which is fed from the Murray).
I know there is work to connect the North and South water supply but pretty sure it's not completed yet. I can ask my mate if you like?
So pretty sure no Desal water will be up north yet.

I'm pretty lucky in that my water is from Myponga Dam which is 100% catchment and nothing comes from the Murray.

The only real way to get your water accurate is to use complete RO and add back what you want.

Cheers,

BF

Certain malts go better with certain waters. The common examples are stout suiting dublin's water and pilsnees suiting Pilsn's.

It's largely about mash pH. Malt will drop the pH of your water down to a level where mash enzymes work best and other effect are minimized (~5.0-5.5 IIRC).

Different malts have different abilities to effect pH. Generally the darker the malt the more it will drop the pH, this effect plateaus off at about 100SRM, however it is not just a matter of using SRM only as your indicator.

To put it simply if you have very hard water you will need to do more to get your water down into the 5-5.5 range. I once brewed a blonde beer with Berri's calcareous water and it was extremely mouth puckering due to astringency caused by sparging at too high a pH.
Meanwhile my stouts were amazing.

So what I am saying is that generally I brew with a grainbill that is designed to bring average para water into the right pH range, and this means for example that I don't brew very pale beers (but I am able to get quite pale beers by collecting the secondary gyle from a amber batch).

This is just from memory, so I stand to be corrected. I can try to dig up some articles if you wish.

Yeah i get what you are saying.

so, by you adding those chemicals to the mash, you lower the mash pH (taking into account malt effect) and similarily into the sparge water. THis gets you ball park of a good mash/sparge pH.

Are Epsom Salts the same as what you can buy in the supermarket? Where do you get Gypsum from?

I only brew ales, from pale through to stouts. I read somewhere that getting the pH around 5-5.5 (like you mentioned) will help with the brews efficiency. I am trying to decide if there are basic additions that would help my brew OR if I shouldn't bother.
