So I recently purchased a ph meter and have been trying to dial in my mash ph. Yesterday was the first time I used it and after 45 minutes in the mash my ph read in at 4.8 at ~70F (meter was calibrated using 4 and 7). I used deionized water from whole foods in columbus ohio. I used the distilled water option in brunwater and plugged in my grain bill and salts and it estimated it at 5.2. Here is the info from the mash.
water
- 5.2 gallons deionized water
- 4.1 grams gypsum (0.8 grams / gal)
- 2.6 grams calcium chloride (0.5 grams / gal)
grains
- 14# 2 row 84.5%
- 1.5# munich malt 5L 9.1%
- 0.5# carapils 3.0%
- 5oz acid malt 1.9%
mashed at 150F for 45 minutes, vorlauf with pump for 10 minutes and than checked the ph. I am just trying to figure out why the ph was so low (4.8). Right now I am thinking the water I am getting is not the same mineral profile as the distilled water in brunwater. I really don't know, but I am going to try and contact the company that runs the water system and see if they have any information before I buy a wards report. Am I missing something obvious? Any help is appreciated.
