With gas stoves, at this time of year its all down to the gas mix how the stove performs. Not all canisters are equal. Please excuse me if I've already said this or its covered elsewhere, but it'll probably help people going out over the next couple of months. The best fuel for low temperature is propane. It's boiling temperature at normal pressure is about is -42°c. The problem for portable stoves canisters is that propane is at too high a pressure because of the low boiling point. N-butane has a boiling point of between -1°c and +1°c. Close to this temperature you wont get any gas released from a canister. Iso-butane has a boiling temperature of about -12°c. I'm going to exclude campingaz as that is only n-butane and is only suitable for spring to autumn usage. Most canisters are blended from propane and n-butane. In cold temps like tonight (-1°c where I live), none of the butane will boil, so only the propane. From what I've seen online, this is usually no more 20%of the content. On a cold morning, you could easily find a canister that has plenty of gas in it, but won't fuel your stove because it's too cold and you've used all the propane. The ideal mix for winter in the UK is propane/iso-butane. There are only 2 makes that seem to guarantee this mix that I am aware of. These are MSR and Jetboil, bot at 20 propane/80 iso-butane. I've only been able to find Jetboil fuel in the UK. It will connect to a standard stove fitting and should power it even when it's well below freezing. Great for a cuppa on those literally freezing cold mornings. [emoji3] Just because it's below freezing doesn't mean you need to resort to petrol etc.
