Brulosophy expert can't tell a Blonde Ale made with straight RO from RO plus minerals

[VikeMan]

Not if the probe is shot.

Possible. It would be quite a coincidence (to happen to match the expected RO mash pH).

Another unexpected oddity is the color difference.

The lack of pH drop for the batch mashed with minerals was an immediate flag for me also. It certainly aroused my suspicion. And so did the picture where the two mash temperatures were being taken. In that shot the two "otherwise identical" batches seem to have about a 2 gallon differential in mash volume. The one on the left is well down in the kettle and obviously thick, whereas the one on the right is well more full.

Hadn't noticed that. So they can't even get the mash volume right but expect us to see their comparative results as valid...
Different mash thickness would also cause PH variations making a direct comparison of measured values meaningless.

Incidentally I clicked on the two side-by-side pictures showing temperature and PH values and discovered one more source of income for Brülosophy.
