Ever had a red ash before?

[Sauer Grapes]

My totally uneducated guess is that there is some mineral in the soil where the brickhouses are grown. As far as the Camacho, it could be a similar situation, or it could be that the water imparted a mineral, or something else into the wrapper/filler of the Camacho. Since I'm making uneducated guesses, it could even have been mold or something similar on the Camacho.
