            No.Cuban pot in you pic is two seperate vessels, so the coffe doesn’t percolate.

            Nope:

        Percolator. The inverted funnel at the bottom has some holes to let water through. Heat will increase the temperature of the water and it will slowly rise up the tube as it does in a drip coffee machine. As the water falls down, it acts like a drip coffee machine, but as time goes on, water becomes darker, and eventually it reaches a point where it comes out the same after going through the grinds.

        For many fans of coffee, the percolator method is an acquired taste.

        A moka pot actually has three chambers. It requires a finer grind as you are only brewing the grinds once, but typically with hotter water and some steam pressure. Depending on your setup, you can somehow pack the grinds in the basket sitting in-between the two chambers, and can achieve some poor-man’s espresso once in a blue moon. Often though, what really happens is that you clog the basket and can’t get much coffee out of it

        Brainlet, a moka pot doesn’t "burn" the coffee because water only passes through it once.

            We’re talking food chemistry, scrotebrain. Try this: make coffee however you like it. Keep a control (cup full) then take the rest and boil it in a pot for 10 minutes. I guarantee you, money refunded, no questions asked, that the coffee that you boiled will taste different. Bitter, burnt. That’s how coffee tastes after its been left on the keep-warm plate for hours on.

            Now instead, pour hot water — most people agree on the 90–95°C range — over coffee grinds, once, and let the resulting pot cool down. It’s how a moka pot works (or a Mr.Coffee, for what it’s worth). It’s almost like a distillation chemistry setup, but with water heating up, the expansion of air allows some higher pressure on the grinds, not unlike an espresso machine.

            At this point I’m not even sure that the replies to this thread are legitimate or just low effort trolling.

              No, mokka pot brews at 100°C.
              Always 100°C, which is too hot hence "burned" taste.
              And you’re the smartest American in the world if you can figure out why it’s 100°C and never 90-95°C.

                If the water in your moka pot is boiling, you’re doing it wrong. It will work but it’s wrong. I put mine on the stove and set the burner at 4 or 5. It takes about 5 to 10 minutes but at no point is the water boiling.

                Also, the difference between 95°C and 100°C is not so bad for the brewing process, because the reservoir pot is not heated, and will quickly bring down the temperature of the resulting coffee. It has nothing to do with a percolator that steadily keeps the resulting coffee at 100°C in the process of brewing it (it’s essentially cooking the coffee).

                >The air pressure from the fully-isolated chamber is pushing the hot water up the tube.
                It’s not air, it’s steam.
                Now where does steam suddenly come from…..

                The presence of air in the water chamber is crucial to the proper functioning. If you fill up the chamber all the way to the top with water, it will yield unsatisfactory results.

                Man these suck so much, honestly the worst coffee I’ve ever had

                  It HAS to boil to generate steam which pushes the water out.

                  >the reservoir pot is not heated
                  You just put it over a flame for "4 to 5 minutes".
                  Of course it’s hot.

                  I have a proper espresso machine with a double boiler and a PID.
                  I know exactly what the effect of temperature is on brewing. – 5C difference is huge and even 95C is at the top of the range you’d probably want closer to 92C.

                    Literally hundreds of millions of Italians have been making coffee wrong, absolutely boiling the fuck out of the grinds, resulting in pitch black undrinkable tar, until they invented the espresso machine. Is that what you believe?

                    >4 to 5 minutes makes it hot
                    The reservoir is air-cooled. I can touch it with my bare hands.

                    >my method of brewing coffee is objectively superior to anyone else’s
                    It sure is. Maybe you got filtered by the moka pot and are unable to use one properly. Your setup sure seems to give more consistent results, but to many, a moka pot is an excellent compromise that produces decent coffee without even thinking of over-engineering things. If you say it’s as bad or even worse than a percolator, there’s something fundamentally wrong deep inside of you.

                    This study asserts that water in a moka pot does NOT need to be boiling for the pot to operate correctly. https://hal.archives-ouvertes.fr/hal-00618977/file/PEER_stage2_10.1016%252Fj.applthermaleng.2008.05.014.pdf

                      Italians are making coffee wrong, yes.
                      Not just in their moka pots but also in their espresso machines.
                      Even some Italians are finally starting to see this.
                      Extracting the natural sweet and acid flavors of the berry, not just the bitter flavors from the roast, is where it’s at.

            It’s not even boiling. The air pressure from the fully-isolated chamber is pushing the hot water up the tube. There’s a high-pressure valve just in case the basket is so clogged and the scrotebrain that you are left it on the stove for too long. It’s clear you know jack shit about making coffee. Larp.

      the hot water goes up the pipe (heat causes it to rise). the water mixes with the coffee causing it to get liquidy. all the solid stuff will stay up above in the basket because of the net but the fully liquid stuff will go through and mix with water below, gradually giving it more and more of a coffee flavor. I don’t drink coffee but it makes me wonder why people (in america at least) buy super expensive coffee makers instead of this cheap and simple pot.

        Generally because different styles of coffee maker result in different flavor, and percolators give you very little control often resulting in a worse cup

        the small disc at the bottom of the kettle in a percolator creates a zone where the water once it boils creates pressure up the tube due to the force attempting to exit a small slit between the bottom of the kettle and the disc forcing the water up the tube and into the grounds basket.

        Makes no sense. The water can’t be pressed up the tube and return to the same chamber, that makes the whole thing just one big chamber, why would there be a transmission through the tube then?

          because of the localized heat in the bottom of the kettle causing the water to boil. due to the water having a high enough viscosity to create enough backpressure through the close fitting disc to the bottom of the kettle it creates pressure which pushes the hot water up the tube and into the grounds basket until the pressure is in equilibrium.

          When the water in the tube boils it creates a low pressure area relative to the rest of the chamber, which new water fills in to be boiled itself. This same principle is used in liquid fueled stoves and lamps.

          The water is only boiling at the base of the tube, I believe.

      Boiling water is converted into steam and rises. The glass at the top traps the steam. The steam cools and recondenses into water. The water is pulled down by gravity through the filter. The coffee raises the boiling point of the water. What is not to get?

        Put a bubble in the bottom of the tube.
        If the tube is thin enough, then the bubble pushes water above it out the top as it moves up the tube.
        The bubbles are generated by water boiling on the bottom of the pan.

          I think the principle at work is capillary action.
          The column of water is lifted up by the bubble. That happens because of gravity I guess. You could say it’s the water being pulled down, not the air being lifted. But capillary action is what makes the air stay in a bubble in the tube, so the water can be lifted, otherwise the bubble would just burst in the tube thereby no lifting any water.

            the bubbles only float up to the surface level, but then another bubble comes under it and so on, the column of water stays there because of the power that keeps a bubble from bursting, capillary action maybe, and each bubble can lift a certain amount of water in a column, similar to how a boat can hold a certain amount of freight, which might be water

            it has nothing at all to do with capillary action. it’s simple gas lift performed by the bubbles of steam trapped in the tube. pic related, from the wikipedia article on gas lift.

                the bubbles do burst when they hit the surface level of the tube – that event occurs at the top of the tube, because the bubbles lift the liquid above them preventing them from reaching the "surface" until they exit the tube. it’s not actually necessary for the bubbles to fill the diameter of the tube, the simple fact that they are rising is enough to lift the liquid, though the efficiency increases as the ratio of bubble to liquid increases. also I think you’re confusing surface tension and capillary action. surface tension does play an important role in gas lift, capillary action – to the extent it plays a role – actually decreases the efficiency of the gas lift.

        no, it’s literally water. as steam bubbles in the chamber at the form and move up the tube, they push the water above them up and out the top. what the picture is missing are the bubbles in the tube and the slits in the reservoir at the bottom that allows water to come in.

            because the steam in the bubbles is lighter than the water in the pot, and lighter than the surrounding air. and once the water in the tube gets moving, its inertia helps carry it up out of the top. the general principle is called "gas lift" and it’s used in a number of applications besides percolators, they are (or rather were) a common household implementation of it.

      What’s not to make sense? You heat the bottom of it with fire. Most of the water that boils will be down in the bottom of that funnel assembly and go up the perk tube. It then rains down on the grounds, pouring coffee into the water. It continues to recirculate until the whole pot is coffee at the strength you want, at which point you take it off the fire, pour a cup, and cry because it’s shitty percolator coffee.

          Because hot things expand and become lighter so they rise. Some of the water boils and becomes steam, and the steam bubbles rise very quickly, propelling more water with it. As for why you don’t get much if you stick a tube in a saucepan, your tube doesn’t have a funnel at the end to catch most/all boiling activity from the whole bottom of the pan.

        I have it, and it works great for me. The tiny filter papers are especially neat. Which coffee do you brew?

        The most mediocre cup of coffee I ever made was with one of these.

          it needs to bloom and be stirred once then add two batches of slightly increasing temps of water (the temp of your water naturally declines and under extracts if you dont)

      i’m happy to say that i have completely cut coffee out of my diet 🙂
      i tried a cup a few days ago and i couldn’t even finish it. seems i’ve lost the acquired taste. now i just need to kick masturbation and i’ll have no negative vices.

        cold shower immediately upon streak break will rob the ecstasy trying to build habitual re-enforcement. also exercise like push ups for punishment same day. This reinforces the idea that weakness should not be rewarded or allowed to thrive, it should be stamped out.

        no, it’s not capillary action. it’s literally the freaking bubbles. they are lighter than the water and float up the tube, in the process carrying some of the water with them.

          being lighter than the water doesn’t explain why they carry water way beyond the water surface level idiot

            same reason sucking on a straw raises the liquid above the level in the glass. differential pressure on the column trapped in the tube. in the case of sucking on a straw it’s done by lowering the pressure above the liquid in the straw, in the case of gas lift it’s done by raising the pressure below the column of liquid with the bubbles of steam.

              no, it doesn’t have a freaking thing to do with the pressure, because it’s ONE freaking CHAMBER

                put a straw in a soda bottle and put your mouth over the opening and blow, it’ll force soda into the straw and into your mouth.

                  wtf are you talking about idiot? if you blow on the side of the straw the soda goes out the straw, not into your mouth. anyway that’s not an analogy for a percolator idiot

                    no, more pressure would be applied on the liquid outside of the straw and force the liquid up through it. there’s less surface area inside the small tube.

                      yeah that’s what I said idiot and it’s in no way an analogy of a percolator, the lift isn’t because of a freaking pressure difference unlike a moka pot

                        it’s the exact same principle.
                        single chamber, pressure causes liquid to lift up above water level through a small central tube.

      the "air" in this case is introduced by boiling water, the air is inside the bubbles.

      What exactly is the point of all these alternative brewers? Just use a drip machine if you’re in a hurry or like 99% of the time. If you want to enjoy some nice beans then use a french press.

      If you put a shot of espresso in a vacuum chamber would it evaporate the water?

      Water has no flavor, so if you could boil it off without heating it that would be nice.

        congratulations you just invented freeze dried instant coffee (starts out as espresso from robusta beans) which can absolutely taste as smooth as regular espresso again without sugar. The trick is never to use boiling water with instant coffee as per instructions.

      Have any of you boiled water before? The water closest to the heat source rises (the reason boiling water gets turbulent is convection: it gets hot, rises, cools and sinks to where it heats up again). Stick a tube in there, water goes up. Number of chambers doesn’t matter, if you’re down to get scalded you could test it with a regular pot and a metal straw.

      in what way?
      i haven’t seen this before, but i can see how it would physically function
      heat source boils water at the bottom, turns to steam and rises into upper cavity, which would need to be sealed, upper cavity expands, pushing down on water below, water is forced through the centre pipe, landing on the ground coffee, and repeat

              but that article is shit too actually because it says drip coffee makers use the same mechanism as percolators but they don’t, they have a check valve forcing water to go through the tube as it expands
