I recently got around to picking up a pH meter and a lomotte water test kit. It's all new so I'm planning on running the tests again before I trust the results but this is what I'm working with currently.
My water pH 7.97
100 PPM Total hardness as CaCO3
50 PPM Calcium hardness
12 PPM Magnesium
50 PPM Chloride
0 PPM Sulfate
130 PPM total Alkalinity
46 PPM Sodium
I have been doing some research on water but I'm very new to water adjustments.
I've always brewed using 5.2 or adding acid malt to the grist.
I've read that the mash pH is acceptable if it is in the range of 5.2 to 6. So I've been looking at a couple of things.
I'm looking at standardizing my grist composition mashing mostly base malt and top mashing the rest of the grist during a 15-20 minute recirc, measuring the pH once all of the wort is collected and using 10% phosphoric acid to lower the wort to 5.2.
I know the grist composition will have an effect on the kettle pH. My current plan is to dose in small amounts until I reach the desired pH. I have been working with a few different spreadsheets but the are all excel and I'm running them on apple numbers and the two don't seem to work well together.
Let's assume a low SRM beer what amount of phosphoric should I start with per gallon of wort?
