I was brewing an Orval style beer yesterday and my PH strips were reading something like 4.8 during the mash.
I built my water from RO. Here's the recipe:
Ca+2 Mg+ Na+ Cl- SO4-2 HCO
Actual 80 9 16 74.0 80.5 100
My grain bill is 7.6kg of pils and 200g aromatic with 48L total water.
brewersfriend estimates that my Ph should be 5.44
My strips are the Precision Labs Ph Strips, stored carefully in their container. I took readings by cooling the sample and immersing the strips for 3 secs and then 30 secs.
I did add the minerals to the entire volume of brewing water, not just the mash water.
This is a problem I seem to be having consistently. I can't tell if it's the strips or not, but I have had, what I believe to be, some issues related to low mash Ph with some of my dark beers, leading to thin, too-light, acidic tasting stouts. But with RO water and a very light colored grain bill, how am I getting such low readings?
