I joined the army in 1972. At one point an old army mess sergeant told me how to make coffee in the field. Put 2 lbs of coffee in a sock and tie the top. Put it in a 20 gal kettle and bring to a boil. Reduce heat and serve. I always hoped that it was a clean sock. If you do not have a clean sock and you do not need to make 20 gallons of coffee, heat water and put coffee in filter and tie top with string (unwaxed dental floss works nicely). Drop filter packet into hot water and enjoy. A large travel mug and a 12 volt immersion heater will work.</font></font></span></p>
