Since the last two threads about mold in a certain manufacturer's tins were abruptly closed for no good reason, in my opinion, I still had unanswered "mold questions" pending. So let's discuss in the abstract so as not to cross the line. I have 21 tins of a blend that will remain anonymous. The blend is subject to the deeming date kill-off. I asked for some advice from the forum members, but thread closed. After discussing issue with unnamed manufacturer/retailer, I have decided, I think, to open them all and jar them and see what happens. I could just send them back for 21 new tins, but I am just not a returner if I can avoid returning a purchase. If I don't open the tins, and the deeming date stays as is, after about a year from now I am SOL if there is a problem. The tins are not vacuum-sealed, so there is O2, and the nice guy on the phone said more O2 would just speed up the process and reveal any problems quicker. So, what say you all, jar them up or just send them back unopened? I really want to put some time on the blend on way or another.
