I’ve had mold form on cold brews before so yea always boil at least a little in the beginning if doing a longer colder/room temperature brew. Once boiled it can sit at RT for days without molding.

I've read people say you shouldn't boil the pods because it 'destroys the effectiveness of the opium', but I believe opium can be smoked - which reaches temperatures far higher than 100 degrees C, so I see no reason why boiling them should be a problem
