X-ray - How Moka - Espresso Stove Pot Works

Find more content on tarantulo.lt/video/xray-how-mo...
In this video, you will see X-ray like footage of the Moka - Espresso Stove Pot combined with sound and video footage from my own Espresso stove pot.
The footage was made with neutron images that show the coffee-making process. The movie was made by A. Kaestner, Neutron imaging, and activation group, Paul Scherrer Institut, Switzerland. The cold neutron imaging beamline ICON was used. The movie is four times faster than in real-time.

Are you a filmmaker? This video is not only educational. It's very well presented. No nonsense. Thank you thank you! Let's enjoy our coffee!

[@TarantuloTV]

Thx. Wanna be filmmaker lol.

[@ibrahimfidann]

Very well made video, honestly i was expecting an animation but came across with better and literal version.

[@TarantuloTV]

Thx. Props for the technical part in the description.

[@ironpun2798]

Finally… a video solve the puzzle once for all what actually happened inside! Bravo!

[@danijelovskikanal7017]

Hahaha, yeah! When i was little i thought it was magic, i think i figured out how the thing works at like age 14....

[@darmawanhabibi6189]

bro this is still amazing video even after the pandemic

[@tonimarx6405]

Thanks so much for this. I felt so stupid that I couldn't quite understand how my espresso pot was working after 20yrs of using it. A visual aid made it so much more simple than a typed explanation. I wish that there had been visual aids like this when I was at school because even though I got straight A's in English I could never adapt it to science for whatever reason.

[@paulallen-01]

I’ve been making stovetop espresso for years. Make it on a medium heat and try not to let it boil. The slower the water transfers chambers the better, stronger and richer it will be.

[@TarantuloTV]

Yes. But this is aint a tutorial, just a how a thing works :)

[@photina78]

You're right, the Moka water isn't supposed to boil. It works by creating pressure to push the water down and then up through the pipe.

[@brettsandler7179]

Good film technique. Coffee making needs improvement ☕😂. Thanks, for the unique perspective!

[@TarantuloTV]

It's just an moka pot tech demo 😅

A bit too much heat? This is a vulcano

[@TarantuloTV]

Yeah I love my daily cup of coffee because of the sound it makes 😃

[@jasonm3343]

Agateophobiadragon how the fuck else are you gonna heat it up? it’s suppose to do that

[@ThatDruidDude]

@@Agateophobiadragon why is this kid so salty, dude get a life. great vid, thanks for your(creator) effort sharing this xray shot

[@VoidsPawn]

@@Agateophobiadragon I was searching for a video that shows how how such a thing works, not how to use it and what do I find? A person who isn't capable of stating a negative opinion without insulting anyone while thinking they're on the right for doing so. How about you try staying polite next time you want to tell someone they're doing it wrong? Especially if it is obvious they did not yet know that it was wrong in the first place.

[@TarantuloTV]

And this video was never about making coffee. Hence as mentioned, there was no coffee inside 😅 - also, it's almost no difference if you make the coffee slower with lower heat or faster with higher temperature. Maybe making coffee slower is a bit better, but nobody has time for that... And again, this video was never a tutorial on making coffee!

[@matthemod]

The only way I've managed to understand this in a simple way, is its kind of like using a water filter in reverse.

[@f1racer908]

It'd be nice if the internal pressure can be measured to see how it compares with home / commercial espresso machines

[@TarantuloTV]

Yeah it would be. I think after some googling you might find someone already measured that :)

[@mosnas6037]

Moka pot about 1.5 bar, espresso 9 bar.

[@photina78]

Moka uses 1.5 to 2.0 bars of pressure, which is the same as the commercial espresso machines used in 1933 when the Moka was invented. The 9 bar espresso machine was invented in 1947, but it still took a few years for the commercial espresso places to upgrade to the new machines.

[@Zzz-dl3nd]

Which one is better ? 😅

[@TarantuloTV]

More pressure, better coffee.

[@ravanabrahmarakshas4263]

i want to see your neutron imaging machine.

[@TarantuloTV]

This video is a combination of footage. There is more info in the comments.

[@JustAnotherDustSpec]

is this diffretn from a vietnam dip ? ( cafe sua da)

[@TarantuloTV]

Yeah it's totally different in temperatures. Espresso pot makes coffee at boiling temperatures. Steams coffee. And cafe sua da is prepared more slowly at lower temperature.

[@mattc825]

Close. Nice video but next time screw the top on more. When it bubbles and spurts like that it's a brewing fail. If you do this again properly I'd like to see result!

[@TarantuloTV]

This was recorded for the purposes on showing how moka coffee works. It did not have any coffee inside.

[@mattc825]

@@TarantuloTV Okay thanks for clarifying. I stand corrected then. ;) Have a good one!

[@Glotttis]

Great educational video but it's not supposed to sputter so violently, or at all. I think heat was way too high. It's supposed to be a nice calm steady flow. Just explaining this to those who may not be familiar with Moka pots.

[@TarantuloTV]

It was a demo. And it was done without coffee inside. And the heat of course was too high to show how it works.

[@drdzdd]

The steam pushing water in the pipe towards atmospheric pressure

[@TarantuloTV]

Yes

[@photina78]

"Though everyday usage of these pots does not require much in the way of theoretical understanding, a number of physics papers have been written between 2001 and 2009 providing models for the process, utilizing the ideal gas law and Darcy's law to provide insights into how the pot works, dispelling the popular myth that a moka pot needs to boil water to brew (the water's vapor pressure combined with the expanding gas is sufficient), and offering insights into the dynamics of extraction.[9]... "The heating of the boiler, A, leads to a gradual increase of the pressure due to both the expansion of the enclosed air and the raised vapor pressure of the increasingly heated water. When pressure becomes high enough to force the water up the funnel through the coffee grinds, coffee will begin to pour into the upper chamber (C). Boiling the water is not necessary - or even desirable - to produce sufficient pressure to brew and extraction temperature is in general not greater than that of other brewing methods.[13][14] "When the lower chamber is almost empty, bubbles of steam mix with the upstreaming water, producing a characteristic gurgling noise. Navarini et al. call this the "strombolian" phase of brewing, which allows a mixture of highly heated steam and water to pass through the coffee, which leads to rapid overextraction and undesirable results; therefore, brewing should be stopped by removing the pot from the stove as soon as this stage is reached.[13]"

[@yannisdran]

So this means that water is boiled? I thought it was just before boiling, but this video proved me otherwise!

[@TarantuloTV]

Water turns to vapor. So yeah it boils.

[@photina78]

No, the water is not supposed to boil. If the water boils the heat is too high. That's one reason Bialetti instructions say to fill the reservoir with cold water and cook it on a low gas flame or a preheated medium electric stove.

[@martenmusicz]

So if you don’t get it here’s some explanation, when the water heats up it starts bubbling, when that happens it passes trough the coffee crushed beans and the coffee flows to the top. if you still don’t get I don’t any more explanation

[@TarantuloTV]

Good explanation boss 👍

[@pavel9652]

Can you explain what happens at quantum level?

[@TarantuloTV]

@@pavel9652 Nothing

[@pavel9652]

​@@TarantuloTV I was trolling the other guy. Thanks for the excellent video! As a total science nerd I appreciate it! ;) Maybe there is nothing worth mentioning on the quantum level, but I see analogies to the Big Bang ;)

[@TarantuloTV]

Haha. Still a nice troll. All props to the laboratory of the original video. Just did the normal camera video and sound.

It is not an x ray video. Might me neutron imagining

[@chumbles89]

You can't just steal someone's video then put a tiny credit in the description. All of the value here came from the group at Paul Sherrer Institut who actually took this neutron imaging video

[@TarantuloTV]

Credit provided below. And the original video is public domain. Also my video ads the context and fhe sound, which was not present on original video. Nobody disputes the value of the Paul Sherrer institute work. Just love moka pots and this video is educating people how they work.

[@jojo_z7508]

Awesome video, thank you. And don't listen to the people saying that you're burning the coffee. The obviously don't know how coffee beans are roasted.

Come on, he is totally running the stove too hot! The temperature of roasting is a completely different thing from extraction temperature.
