MUVNA Mach Mechanical Variable Pressure Manual Espresso Machine

[@cafesing]

After watching MUVNA Mach video, some enthusiastic friends often ask me questions: 1. About the Brew Group head temperature on the Mach machine --- The MUVNA guys are nice; pls follow MUVNA IG and feel free to ask him directly. 2. Regarding the Mach piston movement during espresso extraction --- A full extraction doesn’t always require moving the piston from the top to the bottom. For instance, with a 20g Dose and a 1:1 Ratio, the piston only needs to travel about a third of its range, so just 6-8 turns of the lever will do. 3. How quickly can I reach 9 Bar on the Mach machine? --- 1 second.

What a beatiuful machine. To be able to increase, but also reduce the pressure so minutely is impressive! Kudos!

[@144avery]

It's a mechanical art piece as much as it is an espresso machine. Love that y'all are selling quite daring stuff. Still love my Orca!

[@nathanshelby1446]

I am just loving that manual, minimalist espresso machines are becoming popular the more the merrier as far as I am concerned!

[@os4mike]

That’s so ridiculous. I love it. Do it again

My god this is gorgeous.

You’ve got a good eye.

Unnecessarily over-engineered... Love it! give me 14 of them xD

[@haydenwindmiller8931]

With a stepper motor, transducer and a microcontroller you could flow profile this super easy!

[@cafesing]

Not using hands and only eyes to take part in coffee-making, is that really fun?

[@guillainbarre3004]

⁠yeah turning that handle a hundred times is much more fun. This is more like a diywhy project 😂

[@haydenwindmiller8931]

@guillainbarre3004 oh I agree that the manual experience is far more fun, but when you get to a certain level everyone loves to talk about flow profiling and this would be a simple conversion for those who are obsessed with that

it's ridiculous but it is so damm cool, what if you attach a drill on the crank?

[@omni96]

I kinda wonder how you prevent too long of a pre infusion with these kind of machines. From the way the shots look like, it seems to have similar issues to that of weak flow, which is also causing longer pre infusions.

[@cafesing]

Just turn the handle to start the pressure extraction.

[@sigithw96]

Ok, why they don't make the pressure gauge in right direction?

[@cafesing]

Where do you want to put the pressure gauge?

[@greysuit17]

Seems like the appropriate spot for one.

[@owensparks5013]

Well, it's already a two person operation, so the person at the back doing the winding can have the pressure called out to them...

[@greysuit17]

@@owensparks5013 not a true statement

[@owensparks5013]

@greysuit17 Do I need to explain the concept of sarcasm to you? 🤦‍♂️ Although the guage appears at first to be in a sensible location, according to the video, the user has to stand behind the machine to operate it! If that wasn't enough to make this seem daft, I'd question the crank in its entirety. As fluid passes, the pressure will drop, necessitating continually cranking to maintain constant pressure, easy with a lever, not so much here. As for a pre-infusion or a profile, forwards, backwards a bit, no, too much, forwards again...

[@onocoffee]

Interesting machine, but I think it would be compelling if it were easier to manage - meaning the rear mounted crack has you cranking the machine from behind. Most people don't have or are unwilling to dedicate that much space. Might be nicer to be able to operate the crank from the front of the machine or, it it were operated from the side, to be able to reorient the bezel and gauge to be locked in from the side. But I dig it!

[@cafesing]

Thanks for the advice. With your left hand on the portafilter and your right on the Mach's handle, it feels like you're gripping a car's steering wheel. I think it’s designed to fit our daily routine motions.

[@mactan_sc]

i can already hear the comments asking where the preheating coil/block is

[@cafesing]

I already gave a vague answer in the comments.

[@ReneUhlver]

So many comments from people that really don't understand the sense of this machine.

[@lukedubber5673]

Getting big Meccano vibes

[@blueovalboy]

I don't understand this machine. That looks like a finicky mechanism to turn. Any why 18 bars? What's the point of a machine that can achieve that? It's cool looking, but it looks like it would be a headache to operate. Not to mention preheating and temperature stability.

[@jmeryllman]

It is actually very simple. Not anymore than any manual machine.

[@cafesing]

Honestly, I’m super curious how you get three views from a short video: hard to use + 18 bars? + pointless machine. By the way, I left the blog link with my thoughts on Mach right below the video.

[@puddingstar2340]

I am wondering how it would work in cafes in crowded places like Airports or Underground Train Stations. Maybe 20 cups per day would sell out. But if you want to go more precisely to get flavour notes, my suggestions is to add “Weber SG-1” Stone Grinder 😂

[@cafesing]

Weber HG-2 grinder is cooler 😁

[@LIL-MAN_theOG]

this is for home use...if you use this out in a shop, youre doing it wrong. Using this in a shop doesnt make sense functionally--for there are way better machines that are quicker to use to get coffee to customers.

[@greysuit17]

@@LIL-MAN_theOG it could work in a cafe setting

[@wanaan]

Super pretty, but it costs 4 times as much as my computer.

[@cafesing]

The machine is totally worth it for me.

[@bflmpsvz870]

Beautiful. But needs at least one boiler for heat management and steam wand. La Pavoni Abile all the way!

[@gohkairen2980]

my tiny head couldn't understand how a flat burr hand grinder works

[@cafesing]

As the flat burr rotates, the upper-burr and lower-burr combine to form blades with specific grooves, which cut and crush the beans while pushing them from the center to the edge of the burr.

[@ashes1895]

Use flair same shtt, much better, less pricey(if you aren't star kid)..use electric hand drill for fast turning, aslo for manual grinder

[@cafesing]

First, I love Flair58 and have been using it for two and a half years. But with the Mach, you can adjust the pressure freely. I’m still unclear on what you and others in the comments mean-can you explain the purpose of using an electric hand drill on the Mach?

[@pyalot]

You drop 95° C water into that cold solid block of uninsulated metal that even has heat fins and is at room temperature, you will be „brewing“ at around 50° C…

[@cafesing]

This spot on the Mach machine is ideal for a heating accessory. That’s all I can tell you.🤐

[@pyalot]

@@cafesing so you decided it was more important to show of the shiny metal on the brewing chamber than get drinkable coffee? I mean, sure, we cant taste it trough the internet and you didnt drink it, still, we know you didnt, and ostensibly this is a video about a tool to make good coffee, but who are we kidding. Welcome to Korean content farm cubicles. Also, I dont really know how you want to create great surface contact between your shiny ribbed part (note that ribbed is not flat), and a flat heating element…

[@cafesing]

@@pyalot There are other ways to make heating accessories~

[@pyalot]

@@cafesing well, sure you could use copper coils or ceramic cartridges. The reason everyone uses foil heating elements is because 1) they are cheap 2) they distribute the heat evenly over the contact area (no hot spots) which also helps 3) efficient heat transfer due to maximized surface area and 4) they need almost no space

It's not espresso(

Why not? The puck is being pressed by pressure.
