Alcohol burns with a cool flame so it is not very efficient for cooking. Also, when alcohol burns there is no visible flame, which adds a minor risk of a fire accidentally spreading. When blended with isobutane it burns efficiently even as the pressure in the gas canister fades. A good choice for three season camping, but not the best choice for higher altitudes if you are in cold conditions. Butane Butane is extremely popular in Europe.
Butane is sold in canisters and is typically already pressurized.
When the canisters are empty, they are simply thrown away. Pure Butane burns very efficiently, but doesn t work well in cold weather. If the temperature is going to be below 50 F. you should consider other types of fuel. Also, pure butane does not burn as hot as other blended fuels. If you will be doing three season camping in generally tepid weather, this is a good choice to consider for a stove.
