This time of year? You could use the small bottle, but I like to bring a little extra in the winter, never know if it will be needed as a hand warmer or to melt snow. The small bottle otta work if you aren't really cooking something for long. I've taken the small bottle in sub-zero temps, only boiling water at night and hot cereal in the AM, then I let it run low while I pack camp up, so I can get my hands warm now and then, using my Int'l. Still some fuel left when I check it at home.
