Airtight containers is not the only issue. Roasted Coffee is porous,
and condensation can be a major issue. Opening the freezer causes
condensation. And you can just imagine what happens when you open that
frozen container even briefly in a warm room! You are soaking the
beans, and then freezing and thawing them over and over again.

Unless you allow the sealed container to come to room temperature before
opening. Remove enough beans to provide a week's ready supply before you
need to reopen the sealed container.
