*shrug* an ounce of fuel in the mini atomic burned the same when it was really cold, more or less. Still boiled the water, tho it took a little longer. But the pot doesn't sit down on the stove, and it has a wick primer. A friend's white box clone didn't do as well.

I suppose it depends on a lot of factors. But my cold alcohol stoves have worked better in subfreezing temps than the canister stoves I've tried.
