Most people will tell you that an alcohol is no good for winter weather. Here is a video that someone posted on youtube that might blow that -ism out of the water, not just plain water but frozen ice that is.

The stove is slow to bloom as always but still burned for over 21 minutes. Starting with 750ML (over 3 cups) of solid ice it boiled it for over 7 minutes on one fill of fuel. My guess is he could have boiled at least 5 cups of water before the fuel would have run out. Not bad for an alcohol stove. He wasn't even using the best type of fuel for the stove and that is why you see the yellow flames.
