This adds another step to our water boiling process and additional stove time, which increases fuel consumption. Water from glacial streams and ponds will also increase boil time , so keep that in mind.
What type of backcountry chef are you? Simple boil-only meals are going to use a lot less fuel, while a multi-step gourmet meal will require more. This is another consideration when planning your number of meals before the trip.
As all these criteria change, so too does the way we approach our trip and ultimately the amount of fuel we need in the backcountry. Remember that every trip is unique and plan accordingly. Now that you have a general idea about your environment, conditions and group needs, consider your stove itself. For instance, the Reactor Stove System boils a liter of water much faster and uses less fuel than the ultralight, minimalist PocketRocket stove.
While MSR offers stoves built to meet the needs of virtually every backcountry user and scenario, there are a few constants when it comes to stove efficiency across the models. Our fuel trip criteria offers a baseline to work from, but part of mastering fuel needs is experience, and a big piece of that process is trial and error. When Drew first started working at MSR in , he and a coworker embarked on a climbing trip with the then-new SuperFly stove and only one fuel canister he admits it may not have even been full for an overnight trip.

The more wind there is the less effective your stove will be at heating the pot. The wind will make the flame unstable and in extreme conditions can even blow it out.
The wind will blow away heat and increase your boil time. Use a screen and shield your flame as much as possible by using your body, rocks or a screen. The ambient air temperature changes the baseline temperature of your pot and water. The colder it is the longer your boil time and the more energy and fuel you need to use to get the water up to the boiing point. It took me a while to form my habits and learn how much fuel I needed, but it is a skill you will surely pick up on your thru hike.
Isobutane fuel canisters come in 3 sizes: 4oz. You will likely never purchase a 16oz. I started out my thru hike buying 8oz. Once I had my cooking patterns down, I began to buy the 4oz. Despite their outward appearance, any brand of fuel canister will work with any stove. You do not have to use Jetboil fuel for your Jetboil stove. Many time you will come across a retailer on the trail that only carries one brand. No worries! Buy it. Though most isobutane fuel types are now made as a four season mix, meaning they will function properly despite low outside temperatures, I have heard it helps the fuel to burn more efficiently if it is kept above a certain temperature.
