Any alcohol (by definition) has an OH radical on it that is like 
carrying along a molecule of water. That's why alcohol doesn't put out 
as much heat per mole as hydrocarbons like Coleman fuel. Avoid methyl 
alcohol as a fuel--toxic. Denatured ethyl alcohol is safer. Personally, 
I'd carry alcohol in a metal fuel bottle.

Well, Coleman fuel has a reasonably decent shelf life, but like any 
other hydrocarbon, gets gummy (long chain hydrocarbons) if it 
eva****ates. I'll guess shelf life of Coleman is about 2 to 3 years, but 
that's just a guess. When I used a Svea, I emptied out the tank between 
camping/hiking trips.
