-Coffee commonly comes in ground (as you find in cans), instant((hear me out -- secessus)), and pods.  They vary considerably in **physical bulk** and **cost per serving**. Pods tend to be the most expensive per serving and instant the least expensive.  Pods take up the most space and instant the least.  Buying in bulk affects cost-per-serving, but space is at a premium for 'dwellers.  +Coffee commonly comes as whole or ground beans (as you find in cans), freeze-dried instant, and k-pods.  Objectively they vary considerably in **physical bulk**, **weight** and **cost per serving**. Subjectively they vary  in flavor, ease of making, ease of cleaning, amount of water used, etc.

 Instant coffee will use the least amount of water:  all the water used will be consumed.  Ground coffee, whether loose or in pods, will retain some amount of water.

 +Only the Keurig and drip coffeemakers //require// electricity. Water for press, pour-over, and instant can be boiled over [[food:cooking:stoves#gaseous_fuel|propane or gas stoves]].  
 + 
 +Since it takes the same amount of power to heat a given amount of water there is likely little difference in brewing power consumption between Keurig and drip.  Secessus has noted 70Wh((plus inverter losses)) for drip brewing 500ml of coffee.  For comparison, he observed ~111Wh for kettle on a coil hotplate, ~67Wh for a kettle on induction,  and ~135Wh for percolator on hotplate.((more heat lost to environment))

 Of these only the pods are egregious.  Coffee cans and instant jars can be used as trash containers  themselves (see link above) and filters and instant pouches compress nicely into such containers.  Coffee filters might be tossed into an existing campfire.  Of these only the pods are egregious.  Coffee cans and instant jars can be used as trash containers  themselves (see link above) and filters and instant pouches compress nicely into such containers.  Coffee filters might be tossed into an existing campfire.
