> Winter is no time to take chances.
I have to agree, but that means I take an inverted canister stove.
I guess it all depends on one's experiences. YMMV.
I am going to expand a little on this, as it is very relevant to a lot of winter travellers. For a start, read the article at the start of this forum thread. Next, consider carefully what is going to happen in real life. And for this exercise, let's imagine the ambient in the evening is below -30 C. That's very cold, and getting anything to work under those conditions is going to be hard.
But let us also imagine that you have been = travelling with a pack on your back, and your stove and gas canister are inside your pack. That is very reasonable. So what temperature will your stove and canister be at when you stop? I suggest they are likely to be above 0 C. Very seldom do you hear of a water bottle inside a pack close to someone's back being frozen. Body warmth is significant, and it keeps a lot of your gear 'warm' - so to speak. So even at -30 C ambient, it is likely that the canister of gas in your pack will be at a very operational temperature. You can get that stove lit.
Now, once the stove is lit and running, the canister could cool down due to the ambient. Yes, true, but any one who has travelled under those conditions knows to let a bit of heat from the stove shine on the canister. Or to sit the canister in a bowl of liquid water - although such water does turn to ice rather quickly sometimes. Just make sure the canister stays touchable: below 40 C.
I have a fine photo of some people cooking dinner with a gas stove, and I regret to say they have the canister sitting on top of the lid on the pot! I do not recommend that by any means, but the party was experienced on cold weather travel. I suspect the canister was put up there briefly, to warm it up (or for the photo).
OK, moving along to breakfast. May I suggest that anyone with an ounce of brains would store their gas canister inside the foot of their sleeping bag or quilt, along with their water bottle? (I keep my contact lenses there overnight too.)
Survival in extreme cold means you have to use your brains. And cheat!
