I just got back from a trip that was at around eight thousand feet in the Sierra's. I took three tabs of Esbit for three nights, just to be on the safe side. I was able to boil two full cups of river water three different nights on less than two tabs total – tossed the remaining bit in the fire. Basically, I was able to boil two cups with about a half a tab per boil. If you just want 180-190* water, it'd take even less Esbit. Very efficient and the smell isn't bad at all. Just make sure to double bag it before it goes in your pack or bear canister. I use the Keg-H with Gram Cracker. And I'm in the field at 4.97 ounces without fuel. And Esbit is .51 ounce per tab. Very nice simple solution.
Another said to try it in your back yard. Great suggestion for all your gear. Also, a mini bic would be good for lighting Esbit. Matches get blown out too easy. Esbit is not like Alcy, it takes a bit to get it going. Another great thing about it is it can't spill. -Talk to Rand at Trail Designs and he'll get you the skinny on what you need.
