I am appalled to see that you are charging £750 for one of these units, not even assembled, or with a base or handle! That’s almost double the price of the aram and the robot, which are almost identical to your designs… plus, that’s the kickstarter price, so there isn’t even any guarantee that you’ll send the products!😢 how can you possibly justify such an outrageous price?

Perhaps you could send one to James Hoffman, maybe he'll review it and give you lots of exposure.

All of this is fascinating! Impressive! You solved two main issues of ARAM espresso machine that bothered me the most. Water temperature and pressure reading - this one in such elegant way!!! Awesome!

Amazing, really cool to see all the engineering details, I’d definitely pick one up whenever they become available

I love the thoughtfulness and the simplicity you have given the design.

looks amazing and really enjoyed the assembly/explanation bit it honestly looks like joy to use and cant wait to replace my faulty delonghi with this!!

Do you think you'd be able to design a box to disassemble the press and store it easily for travel?

A very inspiring design - congratulations! A query: Does the metal piston ( and conrod ) result in any significant heat loss; and, if so, would a more efficient material for these components perhaps be preferable? This would minimize the preheat cycles required; especially in a camping/camper environment.

I *LIVE* for well-engineered mechanical devices with elegant simplicity. I wish your team all the success you deserve!

will these be for sale to the general public after the kickstarter? The epoch helix looks like the best manual machine I've ever seen! Wish the algorithm had shown this video to me sooner

I stopped using ROK espresso lever machine because of the lack of pressure gauge and poor temperature stability. I’m now using Flair 58 equipped with the heating element and fitted a temperature probe to make sure I’m pulling a shot at 94C. And even with all that, there is quite a learning curve and tricks to use for the heat consistency. Also, I highly recommend using a puck screen. Lever machine destroy the puck when transferring the water from top to bottom. Else you end up with crazy channeling and a dirty mess to clean. Love the screw system but I can already see it will most likely be too slow when priming the piston (losing heat and time) and then purging after. Manual lever machine are quite time consuming when used regularly.

sometimes a simple machine is the best machine.

Really love what you guys did. Not just only highlight the craft and care that goes behind the the product but also manage to be completely honest about how it work and how it will deliver. Very rare for kickstarter project indeed.

Hi Leonid, the max volume is approximately 90ml.

Two questions: 1) Why would there be a higher concentration of water in the center of a larger, 58mm, basket when water always seeks level, and pressure does not favor one side or the other, it is a uniform force over an area, the only time you get uneven distribution is in flow where wall friction reduces flow at the edges, I can't imagine flow is so high it would cause this. 2) For forces, couldn't the mechanical advantage just be increased to make it easier to pull the shot? Seems like the large amount of accessories for 58mm filter baskets would push a move toward that end, such as a jack leveler. I've been using one of those with my double boiler machine and it is a life saver.

I love the pressure readout! So much neater than a gauge. Do you think that it's worthwhile to preheat your cup before putting the coffee into it? Or is this just a waste of energy

@xaytana

Жыл бұрын

Except it literally is a gauge, it's just packaged to be more aesthetically pleasing. Flexion-based gauges have been used for quite some time, the only new thing here is how its packaged, and really the only reason why it'd be potentially worthy of a patent in the first place. If it's even patent-worthy then, as it's just flexion and lever amplification, the actual patent is probably for the machine as a whole, especially as how the gauge is an integrated part to the lever arm itself and not a separable device, of which then it would be patent-worthy; and probably what allows the machine to exist without infringing on similar machines' IPs. Preheating cups is also fairly common practice, as to not thermally shock what you're brewing, if you're drinking the brew straight. Look at Eastern methods of brewing tea, _everything_ involved gets preheated and rinsed, modernly some derivatives of these brewing methods also have a 'tea pet' of which changes color depending on temperature. Coffee, and really anything that is hot-brewed, should be treated the same way, as to not produce unfavorable tastes; much similar to how brewing too hot or too cold will affect the brew itself. Although I'd also argue that coffee is much more sensitive to temperatures and shock if you're drinking plain coffee, this is also why people will commonly add creamer and sugar, to offset any off-tastes; similarly, this is also why cream and sugar is added to tea, though modernly this hails from a period where pre-modern compressed tea would've been nearly undrinkable without cream and sugar, the basis of this comparison is the bitter notes that both coffee and tea can produce, though coffee can also produce sour notes if not at the correct temperatures. The only real time this isn't relevant is if you're making espresso-based cold drinks, where there's such a disparity in the volume of ingredients that the milk base will cover any off-tastes produced by blanching fresh espresso and really only leaving tasting notes from the brew and crema; you see similar things with fresh milk teas, though milk teas are also typically a much stronger brew to retain the tea's flavor that would otherwise be almost entirely masked by the milk, so it's not a direct comparison, but also shows why espresso is used instead of typical coffee for these drinks. It really just depends on what you're drinking and how you're drinking it, but in reality it's far better to keep everything at similar temperatures during the brew and letting it slowly come down in temperature as a whole to your preferred drinking temperature, even if doing so is more effort and a 'waste' of energy.

Hi Petrus, Personally, we normally use a single 30-second preheat which aligns nicely with the time it takes to do your puck preparation. But if you want to maximise the chamber temperature, two preheats are best.

This is a great video for enthusiasts, no nonsense and lets the machine speak for itself. I think most people are somewhat sceptical with these kinds of machines with the common pressure and temperature difficulties, both tackled in the first 5 minutes. Really exciting, would love to see an independent review as well.

plastic liner?

As a manual espresso lover. This is deeply satisfying

I am very much interested, it is a very clean, simple and ingenious way of making espresso, how could I invest in this project to bring this to the market?

last generations? uses custom one way valve when it wears out replacement will be all but impossible, aluminium torque bar with no way of re-calibrating (aluminium being less than ideal as cyclic loading will have a grater effect as compared to a ferrous metal), custom pivot bushing sure it will have a long service life but if it is damaged during service or use it will be all but impossible to replace, and custom lead nut i like how you glossed over this part in you're video leading me to believe you are aware of its shortcomings.

Very cool, thank you for discussing the elephant in the room which is thermal management. I’m no in the market since I have an e61 machine but I could see myself grabbing one for travel or as a secondary machine.

This looks fantastic

I was just thinking of a direct cylinder espresso machine today. I was imaging two possibilities for water entry. One was a standard spring check valve, which would be much less elegant than yours. The other was a pair of side ports similar to a two-stroke engine. One for entry and one for overflow. All that to say that I have given the design problem at least a little thought and I really admire your solution!

Looks amazing! As with all manual levers though, I have a concern regarding heat loss. At minute 3:20 you show the read out of the brew temperature. So after 2 preheat you say the brew temperature is 95c. In this 30s while you brew your shot, would you know how much does the brew temperature drop? Say from 95c to 85c?

@chronovaengineering

Жыл бұрын

Hi Stefano, we have some further temperature tests planned and we’ll publish detailed results on the Kickstarter page. Right now, the thermocouples we used were located above the piston and in the cup, so the direct brew temperature will be somewhere between those temperatures. Many manual lever machines lack sufficient insulation to maintain high chamber temperatures but our chamber is walled with PTFE, which is a very effective insulation material.

Aram espresso sends a hug

How is this design different from the ARAM coffee maker?

@chronovaengineering

Жыл бұрын

Hi rgalete, Setting aside the modularity of our machines and comparing only the Helix with the Aram, these are the main differences: 1) The Epoch Helix is more rigid than the Aram and the pillar will not bend during use. 2) Our machines are compatible with a standard portafilter size, so you can buy different portafilters or accessories. Using a portafilter instead of a threaded basket holder is also a lot more convenient. 3) We use a coarser thread pitch on the Epoch Helix, so it takes fewer turns to extract the espresso. 4) The Epoch Helix includes a pressure indicator. 5) The Epoch cylinder is thoroughly insulated so you can maintain higher brew chamber temperatures than with the Aram. There are probably additional differences but without testing or disassembling an Aram, we can’t compare those aspects directly. Hope that answers your question!
