Surfers are rugged and resilient. Early mornings, cold water, endless bails and always willing to get up and do it all again. For those early morning wake ups and the energy to keep going, a shot of espresso is the perfect way to start your surf sesh.
Taking the time to properly pack an espresso shot is an important (and super simple) part of making a good espresso drink. I was lucky enough to have Joe Speicher and Mark Wickens from the online coffee culture publication Ground to Grounds stop by and show me the ropes.
Refer to your grinder's manual for its espresso grind setting. You may find that you need to adjust this up or down as you get more familiar with what you look for in a good shot and the type of beans you're using, as the size of the grounds affects the quality of the shot.
Using your index finger, pull the coffee 'mountain' gently to one side, without pushing down, until their is no more mountain and the grounds are mostly level with the top of the basket. Gently drag the same finger back over the grounds in the other direction.
If, when you remove the porta-filter, the surface of the grounds are watery, it means that you didn't apply enough pressure during the tamping process in Step 3. Don't despair, just try using more Force next time. You will eventually get a feel for how hard to push to achieve espresso shot perfection!
Did they give (or do you have for that matter) any insight on why you aren't supposed to twist the tamp? The way I was taught was to fill the portafilter like you said, level it (usually with the back of a knife or handle of a spoon), tamp it once at about 30lbs pressure while twisting it, tap the side of the portafilter with the tamp to shake off any grounds, then give it a second light tamp (I think to resettle the grounds). I'm pretty open to improving technique but I've made some pretty darn good shots that way.
This is super helpful for me because I have so much trouble with this. I have a machine at home. It's not a fancy expensive one, but it's a pump model and sometimes it makes a great espresso. But sometimes not. I do have this trouble with tamping with the right amount of force. Hadn't thought to use a scale to approximate the pressure. Great idea. I think I too often under-tamp.
A good tamp creates resistance (with evenly compacted coffee) that makes the brewing water work hard to saturate the grounds and extract all of that great coffee flavor. The water pressure pulls oils from the grounds and creates the bold taste and rich texture your customers expect from a quality espresso.
Hold the tamper like you're grabbing a doorknob with your thumb and index finger touching the base. This provides two points of contact with the tamper base and helps maintain a level bed of coffee grounds.
Our flagship blend, Streetlevel, is built for balance and approachability and is delicious with any brew method, including espresso. Streetlevel's profile of Guatemalan, Colombian, and Honduran coffees anchors the blend and imparts a complex sweetness with honeyed citrus and red apple notes. This would be the first track if we made a greatest hits tape.
Streetlevel is a coffee that can be brewed several ways and still be a classically sweet and balanced cup of coffee. It has a bit of citrus-like sweet clementine and red apple acidity. That transitions into a honeycomb finish, ending on a well-rounded note.
We created the NEO to be simple, environmentally friendly, cost-effective, and fun, all while producing delicious espresso. We designed this product knowing that Moka pots, many pod machines, and other in-home brewers claim to make espresso, but really only provide you with a cup of strong coffee. Choose between convenient brewing with our Flow-Control Portafilter, or control with our Bottomless 2-in-1 Portafilter.
If you went bean for bean with a light roast versus a dark roast, each would have relatively the same level of caffeine. Comparing our Hola and 454 Horse Power blends, beans from each have a very similar percentage of caffeine.
If you measure your coffee by scoops, light roasted coffee will have more caffeine. Since the beans are denser than a darker roast. However if you weigh out your scoops, darker roasts will have more caffeine, because there is less mass. What should also be noted is that Arabica beans vary in levels of caffeine depending on the plant species.
I want to calculate the band energies of a 2D material with respect to the vacuum level to normalize my band energies with Quantum Espresso. I found a post here, which was not really satisfying for me. Is this the only way to do it?
Another question that I am asking myself is; suppose I apply an electric field in z-direction to the 2D material. Would it still be possible to compute the vacuum level in that case, because my potential would be altered by the applied electric field?
The Diletta has a digital PID that is easy to adjust, again, with simple button presses (the letters stand for proportional integral derivative, but what a PID controller does is precisely control the water temperature during brewing). It also has an adjustable eco mode that that puts the machine to sleep after a selected amount of time to save energy without turning it off. That cuts the heat-up time, which is typically substantial on nicer espresso machines, quite a bit. According to the temperature gauge, the Diletta did heat up in just a few minutes, although after speaking with one of the designers behind the machine, we did wait at least 10 minutes to allow the temperature to stabilize.
The DeLonghi Dedica Deluxe was probably the most disappointing machine we tried, not because it performed the worst, but because of the huge mismatch between its quality and its $300-plus price tag. From the body to the portafilter, it feels pretty flimsy, and the default brew setting filled the espresso cup so high it was impossible to move without spilling. The coffee was surprisingly flavorless; the espresso reminded us of a so-so pod machine. If you are considering the DeLonghi Dedica, we think you might actually be happier with the Nespresso machine passionately argued for by senior staff writer Emily Farris.
The Concierge, which does come with a milk frother, produced fine single, double, or lungo coffees within a few minutes of powering up, but it felt more limited than the Jura E8, the Philips or either Delonghi. The machine was fine, but the competition has really leveled up what an all-in-one super automatic espresso machine can be.
The coffee from the Gaggia was on the same level as the Espressione, but again, the machine is just very limited in what it can do when compared to the more robust Delonghi Eletta Explore and the Jura E8.
OK, this will seem sudden to almost everyone, and even more so to readers on my regular blog, but I decided to break out the chronology of my next couple posts to talk to you about something that excites me a lot. And from that break in chronology comes an announcement that I would normally have made in an earlier post: I am now the happy owner of a DE1 Decent espresso machine, thanks to my Patreon followers who amazingly already backed me up to this level of coffee geekery equipment. I never expected this to happen this fast. I received the machine just a bit more than a month ago, and it introduced significant chaos into my coffee habits, thoughts and plans. Positive chaos, however. For those who do not know, this machine might be better described as a computer filled with sensors that drives hot water through your coffee. It a weird, and delightful concept. If even an espresso machine was suited to me and my almost unhealthy level of coffee analysis, this is the one.
In the equation above, Q is the drip rate, L is the thickness of the coffee bed, A is the cross-sectional are of the coffee puck, μ is the viscosity of the slurry, k is the intrinsic permeability of the coffee bed (how easily it lets fluids through, i.e. the reverse of resistance), a property that depends on particle sizes, shapes, roughness, and pore sizes, and Δp is the pressure differential across the puck that is applied by the espresso machine. The considerations that I mentioned earlier mean that both L and k are in reality functions of the pressure drop, and k is even a function of time while fines are still moving around. The exact ways in which L and k depend on pressure are relatively complex and not too important here, but in practice, the Decent users community has noticed that the combined effect of all these phenomena is a drip rate that depends roughly on the square root of the pressure drop:
Hi Jonathan. Nice article but I am a little bit confused. In the first graph you say This shot peaked at 8 bars, which is in the range typical of a nice espresso shot but in the graph saw 11 bars have I missed something and secondly the pressure and glow is puck pressure no the pump write?
We took the heart of the commercial espresso machines, the wide portafilter, and re-imagined it for the palm of your hand. Tweak your grind, add hot water, and pull a deliciously creamy, barista-level, double espresso.
Far from the traditional espresso machine format, the Picopresso fits in the palm of your hand. But don't let its tiny size fool you. It's a real concentration of power, able to outperform many of its big brothers.
Add espresso ultra-fine coffee to the basket, tamp, preinfuse for 8 seconds and reach a pressure of 9-12 bars during extraction. Watch your espresso fall from the naked portafilter into your cup, breath in the aroma of a well balanced Picopresso shot. That's all it takes to reach perfection.
In 2014, the Minipresso was the first portable espresso machine to use single hand powered piston. This ground breaking achievement has redefined the category of handheld portable espresso makers. Over the time, we have redesigned and improved every aspect of the core technology that power our machines. The newly engineered pumping system of the Picopresso is more reliable and capable than ever, giving you the possibility to extract professional grade espressos.
