Now that the idea has soaked for a while, has anybody done this successfully?

Most of the coffee bags I am familiar with are made from laminated films....polyester/foil/polyester/polyethylene. The foil is very thin and supported by the polyester layers, the polyethylene forms the seals...and has a fairly low melting point.

I cannot imagine these holding up in a fire....boiling food in the bag maybe but not as a cook pot exposed to direct flame.

There must be some sort of coffee package that I have not seen.

Great Idea, Al! Perhaps the pouch could be trimmed and folded to the point where it carries flat in your pocket behind a altoids or similar PSK. You could steam, cook, drink, or store things in such a pouch. Very handy! Exhaust manifold cooking comes to mind (so much more difficult with newer cars)... Coffee bag/exhaust manifold rabbit stew, anyone?

Can you tell us more details. Ex: brand of coffee, where did you buy it, size of bag (or ounces). Thanks for the idea.
