Most jellied alcohol/Sterno has a shelf life of about 2 years, though I have seen it last longer. When going through supplies for events, we always use the oldest stuff and I have found that it can evaporate quickly with a small hole in the seal. Do not open it to see what it looks like and try to seal it back up. It also is not for a short use heat situation as it will not go out once it is lit. Regard it as what it is, a form of napalm. Do not touch it, to not eat it, and do not mix it with any other flameables or caustic materials, unless you like to make things go boom.

Maybe I sould not have said that... <img src="/images/graemlins/smirk.gif" alt="" />
