I was doin' some cipherin' on some water additions last night. In The New Complete Joy of Homebrewing, Papazian gives the ppm contributions of 1 tsp. of few different salts in 5 gallons of water. In How To Brew, Palmer also gives the ppm contributions (per gallon of water) here.
Unless my conversions are incorrect, the numbers from these two sources don't agree. Even if my conversions are NOT correct the conversions don't look like they agree. Just look at CaCl, Papazian gives about a 1:1 ppm contribution ratio from Ca and Cl but Palmer gives about a 2:1 Cl:Ca contribution ratio. Some of the numbers DO agree (but it's not consistent) and I also noticed that in at least a couple of cases Papazian's numbers are exactly half (or double, can't remember) Palmer's.
My copy of TNCJOH is at least 12 years old...should I just go by Palmer's numbers? The numbers I'm getting from Palmer are the ones in the online copy.
Also, what's your favorite 'water recipe' for a Stout (an Oatmeal Stout if it matters). Here's my tentative recipe:
100% Drinking Water which is (ppm):
Ca 60
Mg 6
Na 7
CO3 190
Cl 11
SO4 21
PLUS (addition per 5 gal.):
3g CaCO3
1g NaHCO3
.5g CaCl
.25g MgSO4
According to Palmer's spreadsheet this should give a Residual Alkalinity of 167. If I increase to 4g of chalk/5 gal. it goes up to 178...but I didn't want to push it too far (maybe I already am?). Below is the result (per Palmer's spreadsheet...using 3g chalk/5 gal.).
100% Drinking Water plus additions:
Ca 131
Mg 6
Na 21
CO3 265
Cl 24
SO4 26
Any help appreciated.
