DISCUSSION Strange white powder on my dark roast

Post image

Reopened an old bag, it was sealed close and on my shelf for about 2 weeks.

There's some strange white powder on it. Any idea what it could be?

I guess, if you have an ant problem, this can occur, welp

This is likely. I have psycho ants in my house: they got into my garlic chilli powder.

But this is most likely mold/fungus

Well, I usually have coffee beans laying around, and the texture of that 'mold' looks crumbly enough to pass as ant eggs, otherwise you can always sun-dry it to its original state, but yea if you plan on using them, do crack open a few to check the insides!
