I've never tried my alcohol stove or a canister stove in winter.
Although I can't stand fussing with a Whisperlite in summer, I'm very happy using my modified version for winter trips (see photo). The pot sits on top of the stove which fits through the cut-out bottom of a lightweight metal bucket. The fuel bottle is attached to a bracket that is attached to the bucket with a wingnut. The bucket itself serves as a heat exchanger, reflector and windscreen. Because the stove is suspended off the ground, there is no need for a base. The wires are attached to a rod that can be adjusted to the fuel level in the bottle, so the pot always stays level. The stove also warms up the (well-ventilated) winter tent nicely!
It was easy to make- Spencer should give it a try!
