Gas vs Alcohol Stoves
We are always on the lookout for how to save extra weight. As ultralight backpackers, the ounces even matter. So we recently did some experimenting. This article will take you along for the ride as we used an alcohol stove for the first time, how it went, what we liked and didn’t like, and how it compares to gas stoves like the MSR Pocket Rocket.
There are a few things that spurred our interest in alcohol stoves: a problem that often occurs with gas stoves is not knowing how much fuel is left in the canister. Another issue involves the weight of the gas canister, even when empty. We’d heard great things about the weight of alcohol set-ups, so we gave it a shot.
The First Time
Like I said, we had never used alcohol stoves before. But hey, if they save weight, we decided it was worth our time to explore. Tayson Whittaker, our founder, dropped about 40 dollars, and soon we had a new alcohol stove to check out in the office.
Without using the stove at all, it was impressive how light it felt while holding it in hand. Another perk was that the plastic bottle containing the alcohol was clear with little markings on the side, indicating how many ounces of fluid were in the bottle. That would be useful for being on the trail and rationing fuel for cooking time.
The first few tests were done in the office. We had an overnight backpacking trip planned where we would pit the alcohol stove against a gas stove, so we wanted to make sure we knew how to use it in order to have a fair comparison. Tayson spearheaded this whole effort, and got to play around with the stove.
After digging around on the internet, he found some tips and tricks (I’ll cover those later) and got a feel for how long it should take for the stove to get going, and how long it should take to boil water. Tayson didn’t seem to have any problem implementing those tips in his tests here at Outdoor Vitals headquarters.
But the field was another story…
In The Field
After our team had backpacked in to where we had decided to camp in a lovely slot canyon here in Southern Utah, we were getting excited to run our comparison. We got hammocks, tents, and sleeping areas set up, filmed for some of our ongoing project, and then it was getting to be time for dinner. And that meant we got to play with our stoves! Tayson actually said he felt like a kid with a new toy while messing around with the alcohol stove, whether back in the office or out in the field.
We got everything set up. We had two identical pots with as close to the same amount of water in them as we could measure. With a gas stove (pocket rockets are very common among backpackers, so we had one of those) on the left and the alcohol stove on the right, we were ready to start priming the alcohol stove.
Since alcohol stoves typically take some time to prime, we decided Tayson should get it going first, and then light the pocket rocket as soon as possible afterwards. Alcohol stoves require about 1 oz of alcohol per meal. One tip Tayson had previously found to help prime the alcohol stove faster was to create a sort of small bowl out of tin foil underneath the stove. By putting a little bit of alcohol in the bowl and lighting it, the stove would heat up faster and not take so long to start jetting flames out of the tiny holes along the edge of the stove. (For more details or to see what this looks like, check out our video, we actually filmed the whole thing!)
Alcohol stoves require a windscreen, so once the stoves were both lit, Tayson put that around the pot and stove. We were hoping that this would not only keep the alcohol stove lit, but that it would also retain a little heat so the water would boil faster.
Well, the first try in the field was NOT what we anticipated. In just a couple minutes, the pocket rocket had the water at a rolling boil. The water on the alcohol stove was not even close to that. It actually took 10 minutes LONGER than the pocket rocket to boil water! This was a pretty big bummer.
It’s very possible that Tayson didn’t put enough alcohol in the stove to begin with. He also found condensation on the inside of the windscreen, so maybe it was actually suffocating the stove a little bit.
Needless to say we (and especially Tayson) were disappointed. So we retested after the stove had a chance to cool down. The second time around, Tayson was able to boil water in 6 minutes and 13 seconds, which was much more on track with the research we had done! I guess it just takes some practice sometimes to figure out an alcohol stove.
Gas Stoves vs Alcohol Stoves
So which stove is the best for ultralight backpacking? On the second try, the alcohol stove boiled water in about 6 minutes, while our pocket rocket boiled the same amount of water in 2. The big question now is if that 4 minute difference is worth it.
Let’s jump into some weights:
- Stove: 2.6 oz
- Case: 0.9 oz
- Empty Canister: 4 oz
- Total: 7.5 oz
- Stove: 1 oz
- Windscreen: 0.5 oz
- Total: 1.5 oz
-The weight of fuel for both of these stoves depends on the size of canister of amount of ounces of alcohol. For a canister weighing 7.5 oz while full, you can probably make it last for about 7 days. For 7 days worth of alcohol, it will weigh 10 oz in fuel alone.
7 Day Trip
As you can see, there is a similar weight between the two setups for a 7 day trip, but an advantage that an alcohol stove has is that it will weigh significantly less by the end of the trip because about 10 oz of fuel will be used up. For a gas stove, the canister will still weigh 4 oz when empty.
2 Day Trip
For shorter backpacking trips, the alcohol setup starts out lighter, and ends much lighter as well. If you don’t mind waiting an extra 4 minutes for your water to boil and want to save some ounces of weight in your pack, that’s something to consider.
Other Pros and Cons
Did you know you can actually make an alcohol stove for free? It’s called a penny stove. They can be made out of tin or aluminum cans, just search penny stoves DIY and you’ll have hundreds of ideas come up on how to make one. You can also make a windscreen for free out of tin foil. Then all you’ll have left to buy is the fuel, which isn’t really that pricey.
Like I mentioned before, the stove Tayson bought was about 40 dollars. It is made out of titanium, and so is the windscreen. The alcohol bottle came with it and holds 8 oz of fluid.
Really it seems like most of what we have to say about alcohol stoves is positive. They are affordable and lightweight. The biggest issue with using one of these is that it has more of a learning curve than a gas stove to be able to do it right, apparently.
There isn’t a “one stove beats all” situation here. For us, what it comes down to is finding out what personal preferences and needs are, and then choosing a stove setup that best matches those needs and preferences. The gas stove will always win when we’re talking about time. The alcohol stove wins when it comes to weight and cost. They are both amazing tools to help us get outside and enjoy the outdoors. Keep living ultralight!
