I don't think your total volume of water should be lower than your mash volume. It's hard to see the numbers but I think your total should be 26l?

Does this make sense, it is alright to add 37.8 grams crs to 27 litres of water? that would reduce Alkalinity of 281 to 20? for a pale ale

I've just started learning about this, but I think you'll have to consider the sulphate/chloride added by the CRS as well?

I've also got high alkalinity water in Hampshire and came to the conclusion the totals ended up rather high if I try to bring my alkalinity (265 iirc) down to pale ale levels with only CRS, don't have the numbers to hand though.

 

[Justin Dean]

Y query revolves around after crs addition then ph vlaue.

Per Argentum"If I calculated it correctly, a reduction of 220 ppm alkalinity in 27 liters of water via the use of CRS/AMS should add ~73 ppm of chloride and ~100 ppm of sulfate to your water (give or take a few ppm)."

My data form above says Alkalinity (As Calcium Carbonate) is 281 mg/l, "For a pale beer <20ppm"? i.e. would I be aiming to reduce alkalinity by 261 or so to hit 20ppm for a pale beer? . ?
So if I'm using 27L of water for a batch (Grainfather 11l for the mash and 16l sparge kettle). The scale your guidance allows for an adjustment of 200, I need to adjust by 261 to get 20ppm. Extrapolating the scale up then you say 1.367 ml per l to adjust down to 20 ppm where I am


my gut feel is this is a most unlikely adjustment for the guidance above, so it is matter of using bottled water instead otherwise I'd be looking to add:


half a Camden tablet
15.04ml for the mash of CRS (1.367 times 11) reduction of 260 ppm. For the sparge 21.88ml of CRS (1.367 times 16) IS THIS REASONABLE?


My water report states 124 mg/L Calcium so that should be ok as it's higher than the 100ppm suggested, or I could be aiming nearer 150ppm for the hoppy beers I like, I could ass maybe 3g of gypsum in all split between the 11 and 16 litres in the mash and the spurge, but it is close enough?


If you can confirm my thoughts above? That would help me to conclude my thoughts on this please. I do find this rather confusing but this is where I am at the moment

Yes this look right however that is a lot of CRS to add, probably more than I'd want to add personally. You might be better blending your water with bottled water and adjusting from there. If you blended half and half with Tesco Ashbeck for example it would reduce the alkalinity to around 150- 160 ppm which is more manageable. For your other question, yeah I wouldn't be afraid to push the calcium a bit higher if you wanted to add some gypsum, but again if you blended with Ashbeck then it would also reduce the calcium to about 70 ppm.

 

[Justin Dean]

Great advice. Thank you. I suppose also just use ashbeck and forget the tap.

 

[strange-steve]

Great advice. Thank you. I suppose also just use ashbeck and forget the tap.

Well you could do that, but probably not necessary. Your water would be perfectly manageable for most styles if blended 50:50.

 

[Justin Dean]

Ok. So be it. Thanks mate. Better than boiling tap water.

Planning a strong pilsner soon should I just leave everything as is?
Ca=9 mg=2 cl=10.6 so4=38.6 Na=13.5
Alk=11

 

[Argentum]

I've refined CRS for 27 Liters and a reduction of 220 ppm alkalinity. I now see this as:

1) Requires 32 mL of CRS
2) Adds 76 ppm Cl-
3) Adds 106 ppm SO4--

It would be wise to verify my numbers, as we don't have access to CRS in the States.

How strong is strong? I would probably bump up the calcium to around 60 ppm with calcium chloride.

My numbers are about the same:
31 ml CRS
+74 chloride
+100 sulphate

According to Murphys (who make CRS), an addition of 0.1 ml/l adds 6.4 ppm chloride and 8.6 ppm sulphate.

I have moved several recent posts to a new thread titled Water Treatment so Steve's thread stays on topic.

 

[Justin Dean]

Just done some analysis with delivery test kits. Figures a ppm
100% ashbeck water from Tesco
Alkalinity 16.289 calcium 25

50 % ashbeck 50% my filter tap
Alkalinity 159.31 calcium 100.

Anglian water going through filter tap as I live in Braintree. Unfilterd alkalinity is mot like 283
