How long do opened and unopened tubes last?

Currently we promise 4-6 month shelf life. We recently started to flush the tubes with nitrogen. As long as you keep the coffee in dark, cool and dry place it will last probably longer - we're still not sure since the oldest samples haven't gone bad yet!

Edit: when you open a tube it will age much faster.
