Trangia 27 or 25?

A place to chat about gear and the philosphy of ultralight. Ultralight bushwalking or backpacking focuses on carrying the lightest and simplest kit. There is still a good focus on safety and skill.
Forum rules
Ultralight Bushwalking/backpacking is about more than just gear lists. Ultralight walkers carefully consider gear based on the environment they are entering, the weather forecast, their own skill, other people in the group. Gear and systems are tested and tweaked.
If you are new to this area then welcome - Please remember that although the same ultralight philosophy can be used in all environments that the specific gear and skill required will vary greatly. It is very dangerous to assume that you can just copy someone else's gear list, but you are encouraged to ask questions, learn and start reducing the pack weight and enjoying the freedom that comes.

Common words
Base pack backpacking the mass of the backpack and the gear inside - not including consumables such as food, water and fuel
light backpacking base weight less than 9.1kg
ultralight backpacking base weight less than 4.5kg
super-ultralight backpacking base weight less than 2.3kg
extreme-ultralight backpacking base weight less than 1.4kg

Trangia 27 or 25?

Postby Bill P » Wed 26 Oct, 2022 7:06 pm

I have a 25 series Trangia cookset @ 1368 gr and a newer 27 series @ 953 gr.

Always thought the 27 was 1 person and the 25 was for 2 maybe 3 persons.

Used the 25 series recently for a 4 person trip which went well, except for the persistent demands of " Is that thing on?"

I have an extended 2 person trip coming up and wonder if the " 1-2 person" 27 series will suffice.? Evening meals are home dehydrated @ 120gr/ person.

Has anyone used a Trangia 27 series to cook proper meals for 2 people for say 2 weeks ?

(I'm going to call them 'large' and 'small' sizes, because I haven't verified the model numbers of the sets that I've used, and can't be certain I'm talking about the same thing...)

I bought a 'large' Trangia set in the late 80's and obviously it is more than adequate for two people and by adding an extra-large pot or wok that sits on the pot stands in their up-turned position, I have used it to cook for up to six people at a time.

I have found that when using the standard pots on the 'large' Trangia, It is really only just barely enough for two people if it's an all-in-one-pot meal. However, the 'large' Trangia works fine for up to four people if using both standard pots (eg, rice in one pot and curry in the other, swapping them on/off the burner as required) - which is convenient for us, because we now have two teenagers.

I have good friends (a married couple) who used their 'small' Trangia set for many years for the two of them, and they are not small eaters. So their usage indicates that it ought to be fine for two people. (They now have 4 kids and use two large Trangias!). I do not know what kind of cooking they were doing.

I reckon that if you are doing simple add-boiling-water type of meals, then the 'small' Trangia would be perfectly adequate for two people. But for more complex cooking, especially if using just one pot, I would find the 'small' Trangia to be too small for two people.

Try out a couple of your bushwalking meals in the Trangia at home, and see how it goes! :-)

You probably already know this, but... A Trangia will cook very slowly if the burner contains too much metho. Don't fill it right up - it burns better when about half full. You want the flame to be coming from the small holes around the edge, not from the large hole in the middle.

(I no longer use metho at all - I've got the gas conversion on my Trangia now. Much less hassle, even if a bit finicky in sub-zero temperatures. I now only use the Trangia when cooking for more than two people. It's still the best stove I've ever used, but it is large and heavy. It's amazing how you can cook on it in a wind-storm.)

Whenever I have used the standard two-pot-sized Trangia, one stove can feed about three people comfortably. A main and a side like rice or pasta.


Not related to the OP but I just started using a Trangia mini as my brew kit stove. It is great. I picked Trangia for quality and simplicity, wanted to go metho for a travelling stove as it is easier to find at the other end than the right gas.

The lid snaps on so no need for a strap. It's thin spondonicle works. I will try it for a solo meal eventually but the minis one pot is 0.8L

That capacity is fine for a cuppa, enough per rehydrated meal and would work for a meal that only part of needs to be cooked.

Thanks for the half full burner tip. I have been adding water and the pot has only browned underneath, no black soot.

Thanks for that. I've decided to cop the 400gr weight penalty and take the big one. The small ones pots are 750 and 800ml and there is no way that will feed two hungry bushwalkers.

Thanks Roger,

Love your stove work.

My single person setup is usually a 900ml Ti pot and a Supercat stove with Ti foil windshield.

I havent had to cook for 2 persons for a long time, but I think I should look at getting a 1.5l pot

Cheers Ni..

Yep, same. Bought a Mini about 6 years ago and it has been through a lot. Has not let me down once.

Hi Neo, This is a 10 day trip, I have 5 meals:
1. Aparagus and mushroom risotto, homemade chicken stock
2. Stir fried vegies, onion, carrots, mushrooms snow peas, corn, oyster sauce on udon noodles.
3. Mexican chili beans with turmeric rice. Red kidney beans, capsicum, tomato, onion, paprika, cumin, cayenne.

Final two meals will be made in situ from individual bags of dry ingredients: cooked beef mince, pasta sauce, carrots, corn, beans, pasta. Plus some fresh or found ingredients.

I just bought a 1.9l S2S pot and will use a gas stove, so the big Trangia will now stay home and I have a 1kg weight saving. :)

If you’re using two pots consider carrying a lightweight “soda can” or “tuna can” stove.
That way you can cook with both pots at the same time.

Lots of videos online about how to make them.

Note that the soda can stove is even lighter if you make it out of a Diet soda can! :)
