Such behaviours are rather usual in young and developing fields. For all that, it\u2019s 2017 and we\u2019ve actually managed to acquire quite a bit of knowledge about specialty coffee. We collect data, perform controlled experiments, research, write books and build technologically advanced machinery. We\u2019re finally more gutsy to put on the table a crockery set for Karl Popper.

Pulling shots for more than 30 secs?! Or maybe less than 20? Damn, I\u2019d prefer to drink a glass of boiling tar.<\/h2>\n<p>A classic one. Magical 25 seconds. And don\u2019t play around, kid. I\u2019ve seen so many baristas ditching their shots straight to the sink without trying, just because the extraction time was 3 seconds longer than the yesterday\u2019s recipe said. I saw quite a few trainers and consultants preaching:<\/p>\n<blockquote><p>\u201cIf your shot goes for more than 30 seconds that means the grind\u2019s too fine. You must coarsen!\u201d<\/p><\/blockquote>\n<p>Okay. It does not work that way. I totally understand providing some frameworks for newbies &#8211; most of the times it\u2019s kinda essential. But for god\u2019s sake, why on earth would you cover it with concrete? That\u2019s probably one of the main causes of underextracted espressos being omnipresent in third-wave shops. I\u2019d bet you freshly roasted bag of Kenya against three burnt acorns on this statement.<\/p>\n<p>The number of factors constituting espresso\u2019s preferable extraction time is gigantic. Only a few of them are grade, color and style of the roast, its solubility, mineralization of your brewing water, type of equipment (espresso machine, shower screens, baskets), pressure, flow rate\u2026<\/p>\n<div class=\"cb-alert cb-white\">80% of the most delicious and sweetest specialty coffee shots I tried in my life have been brewed for more than 28 seconds. I still remember that extraordinarily balanced taste profile of Bifdu Gudina we were brewing for around 40 seconds.<\/div>\n<p>It obviously doesn\u2019t mean shorter, less-than-25-sec shots will definitely be underextracted. I had a really nice talk with Gwilym Davies lately and he was telling me stories about full bodied, sweet, less-than-20-sec espressos as well as tasty more-than-one-minute (!) shots from the lever machine. Yep! Here\u2019s a snapshot from his presentation showing some Prufrock espresso bar logs:<\/p>\n<figure id=\"attachment_2596\" aria-describedby=\"caption-attachment-2596\" style=\"width: 1240px\" class=\"wp-caption aligncenter\"><img  loading=\"lazy\"  decoding=\"async\"  class=\"size-full wp-image-2596 pk-lazyload\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"\"  width=\"1240\"  height=\"180\"  data-pk-sizes=\"auto\"  data-ls-sizes=\"auto, (max-width: 1240px) 100vw, 1240px\"  data-pk-src=\"https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/07\/mity1.png\"  data-pk-srcset=\"https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/07\/mity1.png 1240w, https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/07\/mity1-800x116.png 800w, https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/07\/mity1-1160x168.png 1160w, https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/07\/mity1-320x46.png 320w, https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/07\/mity1-560x81.png 560w\" ><figcaption id=\"caption-attachment-2596\" class=\"wp-caption-text\">median &#8211; 29 sec, shortest &#8211; 28 sec, longest &#8211; 32 sec<\/figcaption><\/figure>\n<p>Don\u2019t be scared of time! Don\u2019t be stuck. 25 is not a magical number. None is. Experiment, check out, and what\u2019s most important \u2013 taste!<\/p>\n<h2 id=\"2-americano-is-always-a-slop\">2. Americano is always a slop.<\/h2>\n<p>Well, it\u2019s not. The story usually looks like this. You enter the specialty coffee world as a young padawan. There are a couple of sacred axioms you need to enroll if you want to fully get through the Big Initiation and become a genuine third wave missionary. And one of them is:<\/p>\n<blockquote><p>AMERICANO IS AN EVIL FORCE! NEVER EVER SERVE IT. IF SOME INFIDELS TRY TO ORDER IT, ALWAYS ROLL YOUR EYES.<\/p><\/blockquote>\n<p>As a matter of fact, americano served in most coffee shops is highly undrinkable. I won\u2019t argue with that. But it\u2019s bad not without a cause. Or because that\u2019s how it should be, as a result of its definition. The actual problem with americano might be really trivial. It\u2019s about its essence \u2013 espresso. If your espresso tastes pretty bad you\u2019ll probably still be able to deliver a decent beverage by diluting it with warm, sweet and well steamed milk. But it won\u2019t work with boiling water poured straight from the steam boiler.<\/p>\n<p>Baristas constantly discourage people from sipping americanos, suggesting filter handbrews as a better alternative for black coffee. And that\u2019s the area where great danger arises. Consistent and skillful handbrewing, especially with cone drippers is pretty hard. Brew your client an under or uneven extracted, sour, empty Ethiopian, call it \u201csuper fruity, floral, tea-like, complex with notes of honeydew and hints of orange blossom\u201d and you\u2019ve just shot yourself in the foot.<\/p>\n<p><img  loading=\"lazy\"  decoding=\"async\"  class=\"aligncenter size-full wp-image-1943 pk-lazyload\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"\"  width=\"1437\"  height=\"780\"  data-pk-sizes=\"auto\"  data-ls-sizes=\"auto, (max-width: 1437px) 100vw, 1437px\"  data-pk-src=\"https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/02\/Zrzut-ekranu-2017-02-23-16.07.13.png\"  data-pk-srcset=\"https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/02\/Zrzut-ekranu-2017-02-23-16.07.13.png 1437w, https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/02\/Zrzut-ekranu-2017-02-23-16.07.13-800x434.png 800w, https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/02\/Zrzut-ekranu-2017-02-23-16.07.13-1160x630.png 1160w, https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/02\/Zrzut-ekranu-2017-02-23-16.07.13-320x174.png 320w, https:\/\/www.coffeedesk.com\/blog\/wp-content\/uploads\/2017\/02\/Zrzut-ekranu-2017-02-23-16.07.13-560x304.png 560w\" ><\/p>\n<p>Wishing to be clear, I\u2019m neither trying to persuade anybody to pump out americanos, nor to necessarily drink them. But let\u2019s form a fair opinion about it. Try to brew a really nice, evenly extracted espresso and decant it with pre-wetted V60 paper filter. Add it to a cup filled with soft, filtered, 80-degrees water. Try to achieve a similar concentration as in a nicely brewed filter coffee. If done skillfully, the coffee will be pleasant, fruity and sweet. And there\u2019s a high chance it\u2019ll taste better than 80% of handbrews made by pretentious and condescending coffeemakers. Really.<\/p>\n<h2 id=\"3-dust-is-you-enemy-always-get-rid-of-it\">3. Dust is you enemy. Always get rid of it.<\/h2>\n<p>What I\u2019m calling dust are coffee fines with diameter below 150 microns. There is a belief that dust is a big extraction enemy. We used to remove these smallest particles that \u201cmake coffee more bitter and less clean\u201d with sieves. And then we fell in love with <a href=\"https:\/\/www.coffeedesk.com\/product\/3003\/Mahlkonig-Ek-43-Black\" target=\"_blank\" rel=\"noopener noreferrer\">EK43<\/a>, the best grinder ever. It allowed us to generate much higher extraction yields which made our brews sweeter, more bodied, lively and complex without higher perception of bitterness at the same time.<\/p>\n<blockquote><p>\u201cObviously the particle size distribution is thinner and EK43 must produce less fines as well. That\u2019s why those coffees are so tasty!\u201d \u2013 that\u2019s how our excitement looked like.<\/p><\/blockquote>\n<p>What\u2019s this theory based on? Ah, it must be true because everybody says so, and well\u2026 somehow it works, doesn\u2019t it? And everything would have been awesome if not for one Australian geek and his research that showed EK43 generates\u2026 more fines than many other professional grinders.<br \/>\nFines and boulders are complicated issues. However, it seems that true enemies of extractions in the context of particle size distribution are particles actually much bigger than the rest of the grind. So let\u2019s say it out loud: <strong>coffee dust is probably not a Machiavellian executioner of lousy tasting brews.<\/strong><\/p>\n<h2 id=\"4-a-batch-brewer-nah-truly-best-coffee-is-the-one-hand-brewed-by-a-passionate-barista\">4. A batch brewer? Nah\u2026 Truly best coffee is the one hand-brewed by a passionate barista.<\/h2>\n<p>Let\u2019s be quick and hard-hearted with this one. For most of the time we, as humans, are pretty terrified by a possibility that in some cases we\u2019re worse and just less accurate than machines.<\/p>\n<blockquote><p>\u201cSo what? A piece of metal and plastic is smarter than me?!\u201d<\/p><\/blockquote>\n<p>No, quite the opposite &#8211; and that\u2019s its advantage! It can do stuff mindlessly hundreds of times, you can\u2019t. <a href=\"https:\/\/www.coffeedesk.com\/coffee-machines-and-grinders\/drip-brewers\/\" target=\"_blank\" rel=\"noopener noreferrer\">Batch brewer<\/a> doesn\u2019t have an elbow that can itch. And it won\u2019t think about today\u2019s evening and how to impress that girl, pouring too much water as a consequence. A good batch brewer\u2019s construction allows it to be remarkably precise and stable when it comes to water temperature. Waaaaay more stable than your <a href=\"https:\/\/www.coffeedesk.com\/product\/539\/Hario-Buono-Kettle-1L\" target=\"_blank\" rel=\"noopener noreferrer\">gooseneck kettle<\/a>. In a large scale, extractions from machines are just more even and consistent. I\u2019m terribly sorry\u2026 not! Barista\u2019s task is to think, while integrated circuit can\u2019t do that.

First one in a room temperature, about 25 degrees. I fill up the other one with boiling water one minute before pulling a shot. I measure coffee temperature 15 seconds after extractions. The former cup shows me 73 degrees. The latter\u2026 74. Apart from the one degree difference between two cups, there\u2019s another one \u2013 preheated cup scalds my fingers badly! Luckily, there\u2019s a handle.<br \/>\nI\u2019m repeating this couple of times and it\u2019s nearly the same with 0.4 degree deviations. Preheat your cup or otherwise you\u2019ll serve cold espressos? Probably not. Unless it\u2019s winter and you\u2019re saving on heating.<\/p>\n<h2 id=\"6-damn-press-this-button-right-away\">6. Damn, press this button right away!<\/h2>\n<blockquote><p>\u201cRemember to always press extraction button immediately after assembling the portafilter. The faster, the better. If you wait, coffee starts to overextract and tastes bitter. Okay, that\u2019s all for today, thank you very much. That will be 500$.\u201d<\/p><\/blockquote>\n<p>According to the WBC scoresheet, you have to push the button right away. Then place the cups. If you do it other way around you lose points. Yes, I know that. Once I\u2019ve heard something like this, said by an experienced trainer: \u201cCompetition regulations say that\u2019s a mistake. So it must be and you\u2019re not supposed to do that. In a coffeeshop as well. I find people who make these rules wise, how about you? If this practice wasn\u2019t good, it wouldn\u2019t be in WBC scoresheet, right?\u201d<\/p>\n<p>Well, let\u2019s check it out.<\/p>\n<p>Ten espressos. Same recipes. I brew five of them according to saint rules, pushing the button nanoseconds after setting the portafilter into a grouphead. With the other half I wait 10 seconds before extraction starts. Random order and a blind test. Five of espressos that have been held on taste neither more bitter, nor less clean or worse. There\u2019s no substantial difference in TDS and extractions. Nothing extraordinary happened.<\/p>\n<p>To be clear: Pushing the button right away after assembling portafilters and placing cups afterwards is obviously a good routine that boosts your workflow during rush hours.
