I wish the Decent Espresso Machine had been available When I purchased my Duetto 3 (long time ago) I am really impressed how you have developed the machine as pure hardware which follows software instructions. Wonderful!!

John, this is a great "show-n-tell" and really underscores the value of the DE as a learning tool.

Decent started a trend. Now other mod makers for other machines now bringing out similar sysyems to add to espresso machine's and yes I'm eyeing this machine as my upgrade and final machine. So many ways to adjust everything is like having multiple espresso machine's types in one unit.

I'm looking to buy an espresso machine in the not so distant future. I was under the impression the Decent would be way to high tech for me as a beginner. I'm starting to think now that buying a Decent as my first machine might be the only way to go for me. Just watching some of your videos has expanded my knowledge about espresso tremendously. Thank you so much!

I wound up iterating to this exact same profile. I could have saved 3 bags of coffee beans if I had watched this video first. Oh well, it was a good learning exercise. This really is a great machine. I love the new v1.3 controller.

This particular video is fascinating and I'm sure your very proud at what your efforts have produced. My first thought on watching was, I wonder how many espresso machine manufacturers are using a Decent Espresso machine to explore better ways of making coffee and what changes can be made to their machines to produce better coffee. I'm assuming here that the 9 bar from start to finish is pretty much a dead end. Seems to me a declining pressure curve is quite doable in E61 types and those of more current designs. They may not be able to do it with real accuracy without major redesigns but they could reproduce a declining curve artificially that would still make better tasting coffee. I'm in that waiting period between my order being placed and delivery. It's going to be a long, long month!

First Decent Tiramisu ever!! Love your concept! We will get your pro version next time👍

Absolutely lovely video for learning about the machine's capabilities and how to use them, however I find it very amusing how the shots aren't even tasted at all. It's probably because you can't taste a dozen espressos back to back without overdosing on caffeine, but to some sceptics it might appear telling of how maybe, just maybe, the whole procedure is a little removed from what should actually matter, which is of course taste.

The absolute coffee tool for a barista like me, that use to experiment in every shot

This is so cool! I learned a lot from this video, thank you!

Wonderful wonderful superbly fun and informative thank you

The question I had while watching this was: if you were trying a profile which aimed for 2 ml/s, and the machine ran pressure into the stratosphere to try to hit that rate but couldn't, why was your instinct to tweak the profile to fit what the beans were doing rather than to coarsen the grind a bit to allow the profile to hit its target flow at reasonable pressure? Is it just because you'd defined the exercise to be illustrated in this video not to include any changes to the grind, or is there some other reason it wouldn't have been optimal (if one's overriding goal is deliciousness) to modify grind?

Why do you never taste the shits and tell us what they taste like?

Shots - apologies

is there a training video on what those blue/brown/green lines are and what to do with them?

Can you taste it?

So if you are putting water in that does not end up in the cup, you either have a leakage somewhere or the puck has not been saturated. Don't see what this has to do with uneven extraction 🤷‍♂️

If you liked the flavor, why would the pressure be too high at 11 bar? I look at pressure profiling as a way to get the particular taste you like; why be hemmed in by a certain pressure?

BUT, what did each profile taste like?

Hi. Why the temp.88c only please?

are there any machines out there this complex that doesnt look like i brought my walmart espresso machine into a cafe? really cool little machine but gawd it looks micky-mouse

Hi, there what is the machine that you are using and where I can buy one or similar using pressure profiles?

What kind of scale is that under the machine, does it come with the machine?

Wow. It seems that your machine concept will bury all previous pump machines. Being able to monitor and real time control these variables will inevitably result in better espresso. I assume the popping sound is the pump pressure/flow control making minute adjustments. Is that the case? Is that the limit of pump technology today? In future designs I think you need to figure out how to better house the screen. It looks too fragile, and aesthetically it needs to be improved. What about water temperature control? I assume that is far more limited in terms of speed of adjustments to water temperature, especially a cooling delay. Is it simply boiler temperature? A radiator system would be huge and complex I imagine, but tempering the hot with cool water might be a possibility. What impact on flavor did you find by adjusting water temperature? Are the adjustment increments by degrees Celsius? Thanks for your unique contribution to our mad world of espresso fanatics, and best of luck!

Very nice machine but this is confusing af. I have watch multiple videos but I still don't get it.

you are overextracting coffee , again 35 sec .Will be acidity very high . Way to long
