I am glad that you were able to confirm the dates thing, it might be useful for some more people, definitively was good for myself to check it out. I am also glad your tea seems fine although the pakage was altered. I once had lost a tin of sencha (you might start suspecting, its my favorite type) for many months, including during moving from a house to another, what implyed that the tin was left on a not very dry storage for some time. When I found it I noticed it was a little humid (very subtly) but the flavour felt even more "humid" (not mossy, but, not as fresh as I would have liked). What I did, I got a humidity remiving bag from some food products and stored it in a closed space along with my weird sencha (not mixed or touching, just together). Left it for a couple weeks and tried the tea. It was definitively better tasting. Perhaps you would like to try this with your old friend?
