All Grain Brewing / calcium carry over to kettle question
« on: March 04, 2013, 08:00:59 PM »
The numbers I find quoted are 25% - 35% calcium carry over from mash tun to kettle.
I have assumed the spread may perhaps be related to some brewers using calcium additions to sparge water -> maybe.
I have also seen quoted that probrewers like to use 2/3 calcium in the mash and 1/3 calcium in the kettle.
How much all this is true I don't know but these numers seem to come up most frequently in my research.
So I have been shooting for 100ppm calcium using both calcium chloride and calcium sulfate at various ratios depending if it's a malt forward beer or a hop forward beer.
Mash tun 100ppm calcium
Sparge water 100ppm calcium
That means my kettle carry over is down to 25 - 35 ppm calcium.
Seems to me I would top off my kettle with 65 - 75ppm calcium to hit the 100 ppm mark.
That's a 57:43 ratio vs recommended 67:33 ratio - but close enough I believe.
Is this a reasonable conclusion?
