Default Please check my water adjustments

In effort to learn about water adjustments I've had my water tested and I've been playing with Brunwater. What a great tool but oh, there is so much to learn.

I've got plans for 4 brews this year. I've started with an Amber that has been good in the past with only campden tabs added to the water.
Always wanting to improve I'd like to try adjusting the water and see if the beer improves.

Heres the recipe
6.5# 2row
2# Munich 10l
1.25# Crystal 60
14OZ Victory 25l

1.5 Oz Cascade @ 60minutes
1Oz Cascade @ 1minute
1056 yeast

My water per Ward Labs:
Ca 25
Mg 10
Na 9
K 2
Fe ?
hco3 53
so4 42 (so4-s=14)
cl 24
no3 0.9
total alkalinity as caco3 104
ph 8


Mash water 3.3 gals
Additions in Grams per Gallon
Gypsum 0.1
CaCl2 0.25
CaCo3 0.3

results according to Brunwater

Ca 80.8
Mg 10
Na 9
K 2
Fe ?
hco3 149.8
so4 56.7
cl 55.9

Mash ph calculates to 5.4


Please,
Check my work and make suggestions.
I'm trying to learn.

If I am understanding the reasons for additions/dilutions per style I'll move on to sparge acidification and the fact that the numbers I got back for the water I had tested don't line up with the numbers I get when I use my Aquarium test kit nor numbers that others around town have gotten. But that is a different problem for a different day.


Thank you,
Ben

There is a problem with what you reported for your water. Alkalinity of 1, while highly desirable, is not consistent with a pH of 8 and bicarbonate at 53 mg/L. You in fact must have alkalinity around 46 ppm as CaCO3 unless you are specifying the alkalinity in mEq/L which I sincerely wish the labs would do but in this country they don't. Your alkalinity is 0.92 mEq/L. Also, Ward Labs usually reports sulfate 'as Sulfur' and signifies this with a '- S'. If I assume that your sulfate is reported that way the report doesn't balance. If I assume that you converted - S to as sulfate it does. So did you? When posting a Ward Labs report it is usually best to cut and paste from their e-mail so questions like this don't have to be asked and answered.

First bit of advice: Do not add CaCO3 to mash or brewing water. It seldom behaves the way you want it to and if it does that would spoil most beers. You do not need alkalinity for most beers - you need acid.

Second bit of advice: Have a look at the Primer (http://www.homebrewtalk.com/f128/bre...primer-198460/). It will suggest that you dilute with RO water (1:1 or 2:1 would be enough) and make some simple salt additions. That should cover you for most beers as you learn more about brewing water treatment.

The email I got from Ward only had pdf and csv attachments so I called them up and they sent me this.
Such nice folks.

ppm lbs/Acre 9 in
------------------------------
pH................................................ 7.1
Total Dissolved Solids (TDS) Est......... 167
Electrical Conductivity mmho/cm........ 0.28
Cations me/L................................... 2.6
Anions me/L.................................... 2.5
Sodium Na...................................... 9
Calcium Ca.................................... 25
Magnesium Mg............................... 10
Total Hardness CaCO3...................... 104
Potassium K.................................... 2
Nitrate NO3-N.................................. 0.2 (SAFE)
Sulfate SO4-S............................... 14
Carbonate CO3.............................. < 1
Bicarbonate HCO3.......................... 53
Total Alkalinity CaCO3.................... 44
Chloride Cl.................................... 24
Total Phosphorus P......................... 0.41
Total Iron Fe.................................. 0.02

The total alkalinity was a typo on my part. Should have been 104. I'll go back and fix that.
Yes, the sulfate was given as SO4-S so I did the multiplication per Brunwater and got 42.

Thanks for the reply. I'll go re-read the link you posted and get back to you.
Ben

So lets see if I follow the suggestions in the primer

ideal starting water____ my water____ times over___Diluted water________Adjusted water
_______less than________________________________2:1___________ ____
Na_______20____________9 __________OK _________3________________
Ca_______20____________25 _________OK _________6._______________
Mg_______20____________10 _________OK _________3.3______________
CaCO3____35____________104 ________3X _________34.666___________
Sulfate____20____________42 _________2X _________14_______________
CL_______20____________24 _________OK _________8________________



So, My biggest problem is CaCO3 3X suggested so I should Dilute with Ro water at 2:1 and that should result in the "diluted water" column.
Now an addition of 1tsp of CaCl per 5 gals is suggested as a base line.

How does that translate to the PPM so I can get a picture of how the 1tsp affects the adjusted water profile. The tsp units are throwing me. I don't know how to translate that to an "adjusted water".

It's hard to say for certain, but for the CaCl that I use (Ball Pickle Crisp) 1 teaspoon weighs 4 grams. Ball Pickle Crisp has a small spherical form on the order of 1 or 2 mm in diameter. Not sure what yours look like so it could pack differently in a teaspoon than mine.
