decent espresso pressure profile

In this post, I'd like to introduce readers to the "pressure" and "flow" modes of the Decent. Pump driven machines, as well as rotary ones, are known to be much better than those that brew using steam, known as steam driven. The profiles have seven phases each that can be set to a pressure between 2 and 12 bar and adjusted in 0.2 bar increments. Once you understand what an espresso is, you will have an easier time making one. The steam runs extra hot in order to squeeze the most juice possible out of standard home electricity. Even though most machines advertise 15 or more atmospheres of pressure, in reality, the ideal number is 8 or 9. The volatility of the pressure curves on the DE1+ come from two main sources, as far as I can tell:  clumped grounds and poor puck prep. Within five minutes of turning it on in the morning, the machine is ready to make coffee at a precise temperature -- no sink shots required. Good palate; LOTS of experimentation to subject your coffee to various pressure profile curves to determine the best fit, as there is no right or wrong; Objective and careful reconsideration of classic espresso extraction parameters (e.g. Of course, there are also many other aspects that are key to great espresso: the tamp, the coffee roast date, the coffee dose, bean density, equipment quality, portafilter basket size, water hardness, room temperature… Understanding pressure in an espresso machine is straightforward in many respects. All images courtesy of Decent Espresso. (For the record, we have preferred shots where the flow is steady almost immediately after preinfusion. All Rights Reserved. There are many variations in brewing parameters between espresso and filter coffee that we won’t cover here (grind size, contact time, water temperature, water quality, etc.) Lucky for us, we use the Slayer espresso machine, one of the few espresso machines out there that allows for easy tweaking of the brew pressure.This week, we will be setting out to test the impact of brewing pressure on the resulting espresso and it's extraction percentage. THE SYNESSO STANDARD. Those three measurements you should as a barista check daily and some baristas might even go so crazy that they check those for every espresso that they make. Covid-19 Update - Click and collect and online orders are available as normal. Some of these features are: - Separate flow profiling or pressure profiling. Back in 2016 coffee guru Scott Rao mentioned to me that he was working on what was going to be the ultimate espresso machine. After pulling hundreds of thousands of shots over more than two decades and learning quite a bit along the way, I've probably learned more about espresso extraction in the past few weeks than I had learned in the past ten years. We have a few benchmarks for extraction that have been borne out of years of experience and we are fairly adept at generating enough of it for most machines, but it invariably comes down to flow rate into the cup that determines the quality of a shot of espresso. Pressure increases extraction, therefore espresso extracts far more efficiently than filter coffee does. Making espresso involves pushing hot water through a compact ‘puck’ of grounds at high pressure, usually at around 9 bar (9 times the atmospheric pressure at sea level). It gives all compatible espresso machines capabilities, which were only seen in the most advanced, state of the art devices. The profiles have seven phases each that can be set to a pressure between 2 and 12 bar and adjusted in 0.2 bar increments. For an explanation of the 9 bar standard, see our previous post on the Strada. It allows the user to change the pressure profile, flow rate, and water temperature in real time during the extraction. That good taste likely comes from the very consistent and stable pressure and temperature the Classic Pro is able to produce. They could then determine the optimal profile, and program the machine to repeat the recipe with perfection. Profitec Pro 700 with flow control $2900. This results in a sweet, fruity and medium bodied espresso. Bigger, better, sharper burrs generally produce smoother curves-- that's obvious when I pull shots from two different grinders. Let’s push the limits of coffee. Home machines use cheaper pumps and the pressure settings are pre-programmed for the homemaker. Our next observation deals with the middle region of the shot. There were certainly limitations with this process. Pressure Profiling Regular e s presso machines found at most coffee shops apply a constant amount of pressure (ideally 9 bars) to the hot water (ideally 90C) to make espresso. More advanced machines give a few intervals to tweak the pressure. This miracle machine is the DE1+, from the rather modestly-named Decent Espresso. We are now 3 months in. Please remember, at this point these are strictly subjective results, but we have been able to completely change the face of our espresso program. The brewing pressure is set by adjusting the regulator on the brew pump. Our machine is accurate to an average of 1% of your pressure goal. Immediately after hitting this peak, we back down in a slow but steady fashion to a 3 bar finish. With a long and sweet finish, the fruit notes are more pronounced but not overwhelming. The classic, competent pressure profile I had written about in my ebook Espresso Extraction: Measurement and Mastery was inspired by the profile of a lever machine, and includes preinfusion and a pressure ramp followed by a pressure decline. While these pressure profiling machines were certainly advanced, they were dependent on the barista adjusting the pump pressure exactly the same every time. Ambient & Spresso—The Vesuvius is one of the most recent domestic espresso innovations to incorporate customisable pressure profiles. Typically, coffee and espresso are brewed at a pressure of about 10 bars, and an ideal water temperature is around 195°F. We think this happens due a combination of possible reasons:  the grind is too fine, the puck is too compressed (more on this in a later post), or the puck is still absorbing water during the 15--20 seconds after preinfusion ended because preinfusion didn't fully saturate the puck. The pressure decline in the latter half of a shot can prevent the flow rate from rising as the puck erodes. With little deviation from the normal brewing process, pressure is determined by gravity. Synesso is a reliable company that produces a reliable product. ), Photos by Andrew Rizer at Dash Coffee Roasters and the Canadian Roasting Society |  All Rights Reserved © 2020 Scott Rao, Expert Coffee Roasting & Brewing Explained, Decent Espresso, coffee, espresso, flow rate, puck, extraction, Scott rao, roasting masterclass, coffee roasting, amsterdam. What's amazing is that it can brew espresso using pressure profiling, flow profiling, or a combination, and the barista can see the pressure, flow, and temperature curves in real time during a shot. The advent of the Strada EP allowed for complete programming. Preinfusion works at atmospheric pressure until the headspace above the grounds is full of water, then pressure ramps up as the grounds absorb water, swell, and provide increasing amounts of back pressure. I plan to get a DE1PRO+ if they turn out to be any good build wise. The grinder hasn't been aligned  or fully seasoned and I'm hoping that I can improve the grind quality soon and the volatility will decrease. The duration you brew your coffee will depend on the grind size of the coffee, the roast profile, and the origin of the coffee. Almost all semi-automatic espresso machines are calibrated and set by default to brew at roughly 9 bars of pressure. Respectively, our stainless steel frames, group tops, trays, steam and brew tanks are all cut, formed and welded by a local dedicated team of artisans. © 2018 Branch Street Coffee. More on that in the next post. In pressure profile theory, we now refer to this curve as the Sweetness Curve. However, for all of their differences many of the principals are the same. Back in 2016 coffee guru Scott Rao mentioned to me that he was working on what was going to be the ultimate espresso machine. The #Perfectshot - XT's Flow Profile - Duration: 2:52. As soon as one of those goals is met, the machine moves on to the "rise and hold" phase, in which I've asked it to rise to 8.2 bar and hold that pressure for 10 seconds. Espresso, decent espresso, pressure profiling, flow profiling, Naked Portafilter. Speculations are welcome. In this series of articles, we plan to be completely open about our findings in the hope that other shops and coffee aficionados will be able to learn from our experience. Given that we can taste only so many espressos per day, one can progress only so quickly by pulling shots, tasting, adjusting, and repeating. Brewing pressure is the amount of pressure that occurs during the extraction of the coffee. By grinding finer, we are forced to sacrifice the long sweet finish that is otherwise possible. [X] Hide. That means I can dial in a shot nearly perfectly before bothering to taste it. What's amazing is that it can brew espresso using pressure profiling, flow profiling, or a combination, and the barista can see the pressure, flow, and temperature curves in real time during a shot. There three main things that we want to (at least) measure when making espresso; dose, yield and brew time. Decent Espresso DE1+ $2500. When we use the standard 9 bar profile (and a 2:1 ratio) we encounter a lot of woody tannins. First, a quick look at a standard espresso profile (using the Strada editing software). The DE1+ comes with a tablet computer and quite a few sensors. Browse all the Espresso Machines, and accessories by Rocket Espresso. In the 3 months that we’ve had our hands on the Strada EP, we have found some similarities with the espresso that we’ve brewed. Immediately after hitting this peak, we back down in a slow but steady fashion to a 3 bar finish. The DE1 espresso machine Scott uses is operated exclusively from an Android tablet and provides a live feed of the espresso extraction. But none of those innovations are what makes the Decent the best espresso machine in the world. It's like Cropster for espresso, and once you see it, you'll never want to pull a shot without it. For the most part, 7-9 bars of pressure is considered the sweet spot for pump driven espresso machines, which use a pump to force water through the grounds. With the Decent, it's obvious which shots are worth tasting, which need a finer or coarser grind, and how much each shot channeled. An excellent and dedicated barista could likely accomplish this with some consistency, but how do you replicate this across an entire staff? Next the machine will lower down the pressure to 5 bar over 30 seconds. With our Sidama, the most desirable pressure profile is a slow infusion, with a sudden ramp up to a 10.5 bar pressure. If you happen to find a profile that works very well for an espresso you're brewing, you can save it while still having four remaining profiles to program. However, this may be different for a few reasons. This extends extraction and allows for the sweetness to pop. Browse all the Espresso Machines, and accessories by Rocket Espresso. Welcome to Home-Barista.com™, a site dedicated to the home espresso and coffee enthusiast! It allows the user to change the pressure profile, flow rate, and water temperature in real time during the extraction. The standard espresso extraction takes place at 9 bar. Lelit Bianca DB with manual pressure profiliing $2800. When we stay in that high pressure longer, the acidity is noticeably more pronounced. UK orders Please allow 2 to 3 working days dispatch. Programming in pressure mode is simple and Intuitive. The brewing pressure is set by adjusting the regulator on the brew pump. There are so many sensors that the sensors are literally monitoring each other to ensure they are as precise as possible. Pressure increases extraction so for lighter roasts it might be wise to use lower pressure in the start of the brew so that you will extract less acidity. This marries the best of both worlds: a beautiful fruity acidity, followed by a long sweet finish. This, in turn, dictates a time of 25–30 seconds. The general understanding is that by lowering the pressure throughout the shot, we are able to continue drawing out the “good stuff” and stay below the pressure where the tannins begin to overwhelm the cup. Firstly, the brew pressure may have been deliberately set at a slightly higher or lower pressure. I've had a DE1+ at my house for the past few weeks and I've already learned a ton. We have generally preferred espressos that didn't have such a dip in flow rate, and we're still working on the significance of this. After hearing about it, I went to the Decent espresso website and ordered myself a DE1+ Pro and have been waiting for it to come out ever since. The classic, competent pressure profile I had written about in my ebook Espresso Extraction: Measurement and Mastery was inspired by the profile of a lever machine, and includes preinfusion and a pressure ramp followed by a pressure decline. Most filter coffee extractions take place at 1 Bar at sea level. [X] Hide. So how does our custom pressure profile differ to the standard 9 bar extraction? The pressure decline in the latter half of a shot can prevent the flow rate from rising as the puck erodes. Many have played with higher extraction pressure, and there has been a large push for lower extraction shots as well. The green line is the pressure curve and the blue line is the flow curve. The results tell us subjectively that acidity can be enhanced with high pressure, but only to a limit. The ultimate coffee enthusiast dream espresso machine is finally out and here’s my thoughts after one week with it. After hearing about it, I went to the Decent espresso website and ordered myself a DE1+ Pro and have been waiting for it to come out ever since. The inventor just received approval from Decent Espresso CEO and Founder John Buckman to reveal that the two espresso-tech architects are working together on future data exchange between the SEP and the Decent Espresso system.
