Averagely Perfect Saison - Poll #47 - Water Poll Part 1

Poll #46 determined that the fermentation will ramp up to the target temp over a period of 4-7 days.

The next two polls will determine the recommended overall water profile. The first one (this poll) will determine the approximate Total Permanent Hardness (Ca plus Mg concentration) expressed as equivalent of CaCO3. After that's determined, the last poll will present several possible overall water profiles that fit the approximate Total Permanent Hardness selected.

This poll is straight plurality.

For those looking ahead, after the two water polls, I will publish the final recipes.

This poll will be open for 48 hours.

10 Minutes - 0.75 ounces Saaz , 0.75 ounces Hallertau
Flameout/Whirlpool/Hopstand - 0.75 ounces Saaz, 0.75 ounces Hallertau

 

Just so everyone is baselined...even though the recipe doesn't call for acid malt, you could use it (or acid) to influence mash pH. But I don't plan on making that a poll or part of the recipe.

 

Someone asked me to show what the "as CaCO3" ppm hardness equivalents would look like in terms of ppm for Ca and for Mg, in case anyone was thinking that 50 ppm "as CaCO3" meant 50 ppm Ca, for example. (It doesn't.) So here it is (rounded to nearest ppm)...

50 ppm as CaCO3 = 20 ppm Ca -or- 12 ppm Mg
90 ppm as CaCO3 = 36 ppm Ca -or- 22 ppm Mg
150 ppm as CaCO3 = 60 ppm Ca -or- 37 ppm Mg
200 ppm as CaCO3 = 80 ppm Ca -or- 49 ppm Mg

 

Okay. Soft and Moderately Hard tied. Rather than have a run-off, I'm going to break the tie by assigning the one vote for Hard to Moderately Hard, which is closer to it than Soft. So Moderately Hard it is.
