Finally a compact Caldera Cone Stove System!

The Trail Designs (TD) Caldera Cone system is arguably the most stable, fuel efficient, wind resistant and stable alcohol stove system on the market. But until now aficionados of the Caldera system had to deal with the thorny problem of packing the Caldera Cone into a compact space. The root of the problem is that the tall, springy and somewhat delicate Caldera Cone doesn’t come close to fitting into the cooking pot.

Enter George (Tin Man) Andrews of AntiGravityGear (AGG), the packaging guru who created the wildly popular Momma’s Kitchen. George applied his packing genius to the Caldera Cone for the AGG 3 cup pot to create the Caldera Kitchen. The beauty of the Caldera Kitchen is that it packs an entire two person kitchen including the Caldara Cone into such a small package.

The complete Caldera Kitchen.

Caldera Kitchen contains (clockwise form back left):

  • a 4 cup covered zip-loc container with insulated cozy
  • new asymmetrical Caldera Cone
  • cozy for the AGG 3 cup pot
  • 8 fluid ounce fuel bottle, pot holder
  • AGG 3 cup nonstick aluminum pot with lid
  • TD 12-10 alcohol stove (on top of pot)
  • 2 fluid ounce graduated fuel measuring cup
  • and under it all a green silnylon stuff sack.

The entire Caldera Kitchen weighs approximately 11 oz. Without the insulated cozies it is around 8 ounces. If you take out the pot holder it is down to only 7 ounces. That’s less than the weight of many backpacking pots alone.

The real beauty of the Caldera Kitchen: It packs into this compact shape. (The cone, fuel bottle, fuel measuring cup and pot holder all fit into the 4 cup zip-loc container!)

Other advantages of the Caldera Kitchen are an insulated 4 cup container large enough to re-hydrate a two person meal with room to stir. The meal hydrates better and is much hotter after the usual 10-20 minutes necessary to fully hydrate a freeze dried meal. To re-hydrate food this well you’d normally need to use extra fuel to simmer the meal a number of minutes after a boil. With the meal re-hydrating, the pot is free to boil more water for a hot drink. (I usually have a hot drink while the meal re-hydrates.) The insulated 3 cup pot is also an excellent container to brew hot tea or coffee. The cozy keeps the water hotter much longer than an un-insulated pot which improves both tea and coffee brewing and keeps the drink much hotter. Once brewed, one person can drink out of the insulated pot and the other out of the insulated 4 cup container.

The Caldera Kitchen should also be available for Evernew or Vargo 0.9 Liter titanium pots (left), and the Backpacking Light 500 ml pot right (right). The AGG 3 cup Caldera Kitchen is center. It is possible but not certain that there may also be a Caldera Kitchen for the BPL 550 ml pot.

Very cool! I'd love to see the price and also to hear how the new assymetrical Caldera makes it pack down so much smaller.

Very interesting though- keep up the hard work OR crew!

I've got the AGG Caldera Kitchen for the BPL 500 SUL pot...it rocks! Ingenious combination of off-the-shelf components and custom bits. With some tinkering you can easily fit even more stuff into the outer container, such as foldable utencils, and keep 100% of your cook set inside the plastic cup. It's almost exactly the size of a Jetboil mug, all told.

Sounds like the new cones and an extra cozy - I'd argue the one that really matters, the one for the cup - make a good thing even better. A fantastic set - glad George is there at ORSM frontin' his great goods!

Not really sure when, but when I caught up with Trail Designs and AGG at the show again, they were at the Evernew Booth showing them the Caldera Kitchen.

Part of what makes the Kitchen work is the size of the cone, which in turn is related to the size of the pot. As such the Kitchen is more amenable at this point to pots that are not too tall like the BPL 500 and the AGG 3 cup. This is because the cone had to fit in the one quart container.

too small :( on 08/15/2007 13:27:56 MDT Print View

It's s shame that our idea of a 2-person meal involves at least 4 cups of boiling water, plus room to stir...I don't know how you guys survive on 1.5 cups per person!

Caldera Kitchen for Evernew 1.3L ? on 08/16/2007 06:13:31 MDT Print View

I like my 1.3L Evernew Pot, especially when cooking for two people. Any plans to make a Caldera Kitchen system for it?

Re: Caldera Kitchen for Evernew 1.3L ? on 08/16/2007 06:52:36 MDT Print View

I've heard say the issues with the Caldera Kitchens are that the pots have to be small enough that the properly sized cones can fit into the 4-cup Ziploc.

However, they make Caldera Cones for the Evernew 1.3L

Basically, the Caldera Cones are the main thing. Caldera Kitchens are, essentially, an accessory kit that the AGG guys put together (because they recognized that some of the cones can roll into the 4-cup ziplocs)

I use the ziplock and its reflectix cozy with the larger Caldera cone from my Snowpeak Trek900. It protrudes from the bottom of the ziploc cup, but I stick my titanium drinking cup over the end to protect it. Two light packages; 1: Ziplock and cone inverted in Ti cup. 2: Trek900 with its lid, alcohol stove, and fuel bottle. Much lighter than my old Jetboil and I now have 4 containers for two parallel meals:
Trek900,
Trek900 lid (300 ml capacity),
Ziploc cup, (about 800ml)
Snowpeak 600.

Using the ziploc was the final nut to crack in making this system durable enough for frequent use.

Doug, 'asymmetrical' I believe referrs to the fact that the new cones have more vent holes on one side of the bas than on the other (2 and 3). So you can orient the cone as needed depending on wind conditions and the alcohol burn rate you want.

Anti Gravity Gear Caldera CONE on 08/20/2007 10:41:12 MDT Print View

I just used a CALDERA cone windscreen with my stove for a two-week trip.

The windscreen itself is where the magic of this system takes place.

Some points:

1. Alcohol is tricky, sometimes the flame (invisable) can spread out beyond the pot and I've burned my hands on a standard windscreen set-up.

2. I've played with other stoves under the pot. Some improve the speed of the boil time a little, but the stove that comes with the set is the most fuel efficient (from my minimal research)

3. Be careful! I kinda squashed my wind screen. It still works, but it ain't a sexy as when it came out of the box.

peace!

Re: Anti Gravity Gear Caldera Kitchen on 08/20/2007 11:04:00 MDT Print View

I'm looking for an "adjustment ring" of some sort that can convert a Caldera Cone for the 1.3L Vargo pot to fit a 0.9L Vargo pot.

I have both pots as my wife & I always backpack together, sometimes with one of our grown kids or another person or two. I guess it can be said that we don't skimp on food while on the trail (granola bars are between meal snacks, not the entree). Two pots come in handy but I don't think I want to buy and pack two Caldera Cones stove (even though they are lightweight).

If I could find an adjustment ring that would fit inside the larger 1.3L cone that would securely hold the 0.9L pot, I would be in Caldera heaven.

Evernew Caldera Adapter Ring on 08/20/2007 12:40:30 MDT Print View

Interesting idea... it seems to me the idea was broached at some point. I can't remember what the comments from the TD guys were though.

If it were done right, it could work (though you'd get a good bit of reduced effeciency with the 0.9L). I think the difficulty was in getting it to work.

Caldera Adapter Ring on 08/20/2007 13:01:21 MDT Print View

I contacted TD recently with the idea of an adjustable cone. They said no. Because of the need for a precise fit to hold a pot of boiling liquid, it would be dangerous to make the cone adjustable.

I also asked them about whether they would sell just a cone for a second pot for people who already owned a system. They seemed interested.

That's sounds like the TD guys (and I feel stupid not having thought to mention that route). They are very cool.

Mike, if you contact 'em directly, they'd probably be able to work something out with you... that or they'd work something out with AGG/TinMan and you.

Michael, Rand and Russ would have an engineering-fit if they saw this recommendation, but just punch holes at the top and bottom and use wire ties to hold it at the reduced diameter to fit your smaller pot. Of course that will screw up the height-diameter ratio and might make the system less efficient.

Better solution, buy one more cone; you don't carry both pots at the same time, do you?

Ziploc lid on 09/02/2007 12:40:49 MDT Print View

I think it would be OK, when using the complete Caldera Cone kitchen, to leave off the ziploc lid (.6 oz). At least for the BPL SUL 500, putting the Caldera Cone, fuel container, measure, and stove in the ziploc tube, with the pot lid on top, stowing the ziploc bottom into the SUL 500, and stuffing the whole shebang carefully into the stuffsac, the cone seems pretty well protected without the ziploc lid (which threatens to mash the cone anyway, unless one makes sure it's pushed well down into the ziploc body.)
Total weight: 6 oz.
Memories of alcohol flaring in the dark: Priceless

'I think it would be OK, when using the complete Caldera Cone kitchen, to leave off the ziploc lid (.6 oz).'

Of course, then you can't use the lid... which raises the question, if you don't need to use the lid, why bother with the ziploc container at all? (and why bother buying a 'kit'chen?) Just by a BPL500 Cozy and get a bag to fit it all in. The solo red cup that the cones ship in would provide a similar amount of protection as the ziploc cup sans lid.

Flipping the Lid on 09/07/2007 11:42:05 MDT Print View

Joshua--



I don't remember mine coming in a solo red cup, but yes, if the red cup is a plastic tube rigid enough to protect the cone from crushing, it would be fine. Caldera probably chose the Zip-Loc because it was cheap and off-the shelf; my point was just that the lid is pretty heavy, and if one is using a stuff sac to contain everything, may not be necessary. You raise a good point--there may be other plastic tubes still lighter that would do the trick.

The cozy and stuff-sac probably wouldn't be rigid enough to save the cone from being squashed, unless one were consistently careful in ones packing--not an impossibility.

SUL 550 pots on 09/15/2007 23:46:16 MDT Print View

I am wondering, the new 550 versions of the firelight pots, will they fit in the Caldera Cone system made for the 500 pots?

I am considering getting that combination, but the caldera cone will be pretty much worthless to me if the pot wont fit.

I will be looking at the pot with handles. Ill probably also get the full kitchen

Cheers,

Adam

>I am wondering, the new 550 versions of the firelight pots, will they fit in the Caldera Cone system made for the 500 pots?

The answer is....not really. While the diameter of the 550 pot is the same as the 500.....and will be held snugly and hang off its lip.....the 550 is taller than the 500 and as a consequence it is too close to the stove and really hurts efficiency. So....yes....you can shove the two together....but you likely won't like the way it runs.

Hope that helps!

"I don't remember mine coming in a solo red cup, but yes, "

I think they package it in the red "solo" cup (think the kind you buy 20+ for 6$) when ordering it SANS kitchen.

Great Kitchen set! on 11/12/2009 20:40:07 MST Print View

I've used my Caldera Kitchen for the AGG 3 cup pot about 10 times now. It's a great setup and everything packs together very nicely.

The stove works flawlessly and is far more efficient than any of my homemade alcohol stoves. The system seems impervious to wind.

One of my hiking buddies has mentioned that the size seems to be a drawback if you're limited on pack space. It seems small enough to me; especially considering that it contains EVERYTHING (pot, lid, cup, cozies, lighter, fuel, stove, windscreen). I love it.

Perfect all-in-one system for me.
