Ph of mash, pH strip reliability, and mash being too acidic.

Post #1 made 10 years ago
well, I have my second BIAB in the primary and one in the secondary. Same general type, American IPAs. I used pH strips purchased at my local brew shop and for both batches it indicated a ph below the dynamic range of the strips (4.5 I think). I'm partially color blind and have always had difficulty with colorimetric readings. That said, what happens to a mash if it's too acidic? I know the problems of it being too basic. I did adjust my water with salts per specs ( though I can't recall what program/spreadsheet) but I did not note which software in my log (dumb).
My next batch, I'm tackling a Pilsner so want to know what a low ph mash would cause there. I don't trust ph strips. Any advise? :think:

I'm also partially colorblind, and I tend to send pictures of the strip w/ color legend to a few people to confirm the reading for me.

This page should tell you anything you need to know about the effects of your brewing water.

As for the accuracy, I just check it against the free spreadsheet on the website I linked. So far so good, brun'water has been just as great of an asset for me as the BIABacus from this site.

This site recommends the paper DuoTest strips on Amazon, which is what I use. I believe Martin also recommends some on the page I linked.
