Averagely Perfect Dubbel - Poll #34 - Specific Concentrations for Chloride and Sulfates

-> Poll #33 <- determined that the general water profile will be Medium in Chloride (75 -125 ppm) and Low in Sulfates (less than 75 ppm). This poll will determine specific concentrations (in ppm) for Chloride and for Sulfates. When they have been determined, the concentration of Calcium will naturally follow, since the Chloride and Sulfates will come from additions of Calcium Chloride (CaCl2) and Calcium Sulfate (CaSO4), respectively. (A possible sidetrip here would result if there is a clamoring to consider adding some sodium via NaCl. In that case, some of the Chloride would be coming from NaCl.)

In this poll you should click on two checkboxes... one choice for Chloride and one choice for Sulfates. Do not click on more than one choice for each ion. If you want an amount that's not listed for a particular ion, write it in, and don't click a checkbox for that particular ion. Write-ins need to be clear... if I can't understand what you're saying, or if it's not clear that it's a write-in, it will get ignored. Write-ins must be consistent with the previous poll decisions, i.e. Sulfates votes must be for less than 75 ppm and Chloride votes must be between 75 and 125 ppm.

Feel free to include comments about other aspects of the water you believe should be polled.

This poll will be open for 48 hours.

If you have issues with or suggestions for methodologies used in this project, please send them via beermail. Let's keep the threads themselves on topic to the question at hand and not about how you would have asked the question differently. Lobbying for votes and intelligent discussion of each choice's relative merits is encouraged.

The Averagely Perfect Dubbel Recipe so far...

5 Gallons into the fermenter
Target ABV: 7.0%
OG: 1.065
FG: 1.012
IBUs: 24 (Tinseth)
Yeast: Wyeast 3787 or WLP530
Mash (recommended): 60 Minutes @ 152F
Assumed Mash Efficiency: 70%
Boil Length (recommended): 60 minutes
Fermentation: Pitch at 66F, ramping up naturally or via temperature control to 73F over 2-3 days)
Overall Water Profile: Medium Chloride, Low Sulfates

Grains/Fermentables:
---Belgian Pilsner Malt (86%)
---D-90 Syrup (8%)
---Caramunich (4% Total)
---Special B (2%)

Hops:
60 minutes: Styrian Goldings (1.2 ounces, 5% AA)
10 minutes: Styrian Goldings (0.5 ounces, 5% AA)

 

Ok, that averages out to 90 ppm Chloride and 41 ppm Sulfates. That brings Calcium in at 68 ppm.
