EDIT: Before saying "you should've used a more clump prone grinder," consider the results. The BEST method is exactly the one that actually ADDED clumps and caked grounds. You're working from a completely unproven baseline of WDT is necessary for declumping. This has never been proven. Even with clumps and caked grounds, the shaker was the best. Tamping seems to alleviate clumps. This was hypothesized years ago by Perger and even more recently by Samo Smrke, the university professor of Chemistry whom I consulted in this video. Cheers

I've always maintained that WDT is more significant the less consistent the equipment (grinder) is. These results seem unsurprising and logical to me.

[@at4mama1]

[@ScarsOfAFracturedSou]

I think that, WDT and the Moonraker and such, the grounds are being sorted with the smallest grinds at the bottom and the largest to the top. The problem being that grinds of a larger size, are getting less water contact time. In the blind shaker, even distribution where the fines and boulders are homogeneous, it produces an even flow (Pearl Jam). It's less like mixing chocolate chips in cookie dough and more like mixing sand, gravel and rocks with water, the sand will always find its way to the bottom, and then the gravel then the rocks. So we are left with the 007 of distribution, shaken not stirred.

[@paul--b]

[@macehead]

[@LongLiveCoffee]

I grind to the Sette 270's cup. I shake it a bit. Throw it into the basket. Gentle tap. Wdt. NCD like distributor. Tamp. Puck screen (i don't like the concentrated water flow of my machine). Extraction time.

[@florinchis4051]

When I had a $200 grinder, I wasn't able to pull decent shots without Wdt. So as you said, a cheaper grinder could benefit greatly from the Wdt. I think the Webber grinder does such a good job with particle distribution that from that high baseline you can only screw it up with Wdt.

[@zeltwood...]

Just bought the Blind Shaker. Been asking myself this question since I first started as a Barista. And Lance always has the answer. ♥

[@koffiezet]

My main reason for using the 3d printed Umikot is that it makes the puck prep consistent, no matter what, and I haven't really had any bad shots since I started using it, which certainly wasn't the case before. I often had channeling issues, probably because I wasn't paying attention or had a sleepy head, and I have the feeling this saves me from all of that. Could I have better extraction using another method? Maybe - but I'd also have a lot more terrible shots too.

[@bitcoinsig]

The glass from the Costco Delici Sea Salt Caramel Mousse cups perfectly fit a 58mm portafilter and are great for this distribution method.

Morning Lance, I really liked the style of presenting your findings! In the future it would be helpful for me personally if you'd make a little colored mark in the finding sheets when you talk about specific points in your results. Specifically shot time and extraction sheets were shown for a few seconds and then your got to the next subject. You might argue: pause the video and so on, but I don't want to. You got an interesting subject, you present very good, but with the speed you have I am getting a bit behind comprehending and would like to see the sheets a bit longer and some highlight markers over the current subject. Content wise it really helped me. I use a sage expresso grinder, cheaper than the weber and it really helps not choosing to grind into portafilter and try the shaking the grounds in the container method. Thank you for the effort! Gratings for Germany. ❤

[@hcr32slider]

Great video at the perfect time. I've been struggling with one sided extraction no matter how much I use the wdt method. It was only the day before your dropped this that I pondered whether it was caused by sitting the portafilter on the grinder holder as it was throwing the grinds towards the handle. Simply holding the portafilter and moving it around proved the plausibility of the idea as i had back to back perfection extractions after this. This video has expanded on that and filled in the blanks. Can't wait to play with some shaking. Cheers dude

[@petemaloy51]

Only one question, does higher extraction yield make a better tasting coffee always? In the audio community what measures great does'nt always sound better than that which measures worse. Keep up the good work.

[@danmcvicker3620]

Also wondered the same.

[@ma0ww516]

If I remember correctly, the belief in this metric is that higher extraction yield in the shot = a better overall distribution of water over the grounds, which directly correlates to a more uniform distribution of grounds in the portafilter and lack of clumps or other physical abnormalities, prior to the tamp. An inconsistently distributed, clumpy basket would thus be limited in terms of extraction in comparison to one where water is allowed to flow evenly over the entirety of the puck.

[@treyrmason]

The short answer is “no.” The long answer is that it depends on the coffee. Some coffees taste best at 23% extraction. Some at 17% extraction. Some in between or outside those numbers. What matters is being able to consistently control what variables you can to adjust the extraction predictably and reliably. At the end of the day, what matters is how the shot tastes, and if you had some nerdy fun along the way then that’s even better 😁

[@ash2joker]

Thank you Lance for all these recent brilliant uploads. This in particular, relived me from massive frustration that I was going to change my grinder. I was directly grinding into portafilter and getting really skewed results. All fixed now, thanks to a few shakes before dosing!

[@franciscorosario2709]

Great video! Interest results, I would like to know if the shots were also tasted to check which method pulled the best tasting shots. Just curious because higher extraction doesn’t always mean better tasting shots, so the combination of this data would be more helpful I think

[@baselsalam]

Thank you for all the effort you put into this. Since most people don't have a Weber shaker the results won't help unless we all get a Weber shaker :(

[@MichaelKire]

So what I see here is that you've tested more or less the worst scenario (meaning the best grind and least clumping from the get go), which makes these tools have less to do. I would love to see the opposite. You could keep the grinder etc as you already have, but instead introduce more clumping before doing your tests. An idea could be pouring the coffee in, do a tamp, and THEN rip all up using a spoon or similar, use the chosen tool afterwards, then retamp. Then you should have introduced a lot of clumping and should allow as much as possible of the declumping to the tool you're testing. But as always, great videos. Great that you are testing as vigorously as you do

[@Sebb747]

I agree in general, but tearing up a tamped grounds will be horribly inconsistent and quite far from reality. Better to use a more common household grinder in the 150€-500€ range, which would also be a far closer match to a home barista setup.

[@MichaelKire]

@@Sebb747 that was my initial thinking too. But I then realized that a household grinder would add lots of variability in grind size too, making them unreliable for this sort of testing.

[@allen.t]

That’s exactly what I was thinking and feel like this definitely needs to be redone before Lance praisers go preach this message everywhere that blind shakers are 100% the best.

[@tanpreetsingh696]

Agreed, these were already distributed via 1 method, so he’s really just resting a 2nd layer of distributing making this entire test/video useless

[@error.418]

It's a neat idea and a fun experiment, but I don't see how that actually makes a difference for reality. If the shaker was doing enough and in less time while the other tools weren't able to improve upon the base scenario it created... then I'm not sure the data coming out of this artificial tamp and break would say much that's useful.

[@ominguti6345]

Great video, thanks. It echoes my experience with coffees from very light roasts to neapolitan in my la pavoni europiccola manual lever and I thought I was doing something wrong(likely I was using WDT wrong). I have a 0.3mm 9-needle wdt tool and a small (4x4cm) tupperware container. I always get the best results when I grind into that tupperware container, I shake it a bit, I put grounds into the portafilter and I only use WDT on the very top ~2mm of coffee to distribute it evenly. Then I give it few taps on the table and tamp. This is my most consistent, best extraction ever technique. Every single time I WDT'ed the entire depth the results were worse. My observations go even further, I use Eureka Mignon grinder and it doesn't clump much. I noticed, especially with very light roasts that I grind very fine (they are prone to channelling with slightest unevenness in distribution if not pre infused a looong time) when I ground directly to the portafilter I got much better results just using the WDT tool to distribute the very top 2~3mm of grounds than "going all the way". I'm glad to see my subjective experience validated scientifically by your video :-)

[@JB-bp3nz]

As someone who has actively resisted the WDT needle tool movement this video makes me very happy!

[@IDeeprootedI]

Awesome work! Makes absolute sense when you think about it: Shaking homogenizes the grounds so that fines, boulders and everything in between is distributed as randomly as possible and thus giving an even flow through the puck. Clumps don't matter as they are smashed by tamping. What WDT in contrast does, is distributing a significant "mass" of grounds around the basket. While not necessarily bad, it is not actually "mixing" all the differently sized particles around at random, as the shaking does. So there will be areas with more fines and slower flow as well as areas with less fines and faster flow and basically channeling. So even though the "mass" of grounds is distributed around in the basket evenly, the particles themselves are not mixed evenly. If done excessively (and depending on consistency of the technique) it should probably even cause the fines to separate and migrate to the bottom.

[@Santibag]

It sounds like the shaker is doing a macro management of the grounds, and distributing them very well. The needles do something closer to a micro management. And with micro management, you are almost working on every grain of ground coffee individually. With a perfect micro, you shouldn't ignore any ground until you reach the optimum management level. The needles are not small enough to only affect one ground at a time, so it's not a perfect micro. But possibly, it does quite a little in terms of macro, and leave tons of grounds untouched. And possibly, it hurts some grounds, because the grounds are not necessarily managed well.

[@JonFairhurst]

I agree. The shaker is mixing fines and boulders to make the grounds more homogeneous. Excessive WDT might even make it less homogeneous as the fines fall to the bottom and the boulders stay on top. I personally find that fluffing in a small, rounded bowl is even better than shaking in a cup with corners. It does the macro homogenation while also avoiding clumping. But maybe it’s just a matter of technique. Don’t shake the shaker like it’s a cocktail; toss the contents like it’s a salad. And if WDT is needed to break up clumps, do it first, then toss, pour, level, and tamp.

[@mugglywumps5408]

Helpful! I've been using a regular wdt and consistency has been a big issue, leading to channeling. Gonna try out a different setup!

Since I have a DF64, I dose in its cup, then put it directly on top of the portafilter just like you did at 14:15. The problem is that IF you don't shake most of the coffee sits on one side... basically there's more ground on the side that falls first. So I use needles (cheepo WDT tool) to distribute. Strangely enough, and as you mentioned, WDT doesn't do much about this. There is still more ground on one side, so much so that after tapping the PF on the kitchen top, I have to "touch up" the surface and move some grounds to the other side. I'll try to change the routine and simply shake like you're preparing a cocktail (although it will probably be slightly messy as the cup isn't a perfect fit), and then touch up the surface. Then see if I get more consistent shots, since I log every shot anyway.

[@darylfortney8081]

Incredible research

[@fscottqc]

A question I’ve had about WDT all along is whether it’s actually accomplishing much. The clumps in the coffee are not as tight as the tamped coffee. So tamping alone is going to break up the clumps. This, to me, makes a whole lot of sense. WDT is merely properly distributing the coffee prior to tamping. So it doesn’t help if the coffee is already fairly well distributed. However, it is very useful in getting proper distribution across the filter basket. Thanks, Lance!

[@johnnychristakis3885]

Lance is really on one of his greatest video streaks maybe in his career. Amazing info in this

[@sohailhines]

I have a Eureka Mignon Libra (weight based) grinder. When grinding directly into a naked portafilter, my friend and I consistently noticed that the same half of the basked would saturate/extract before the other half. After many more shots, we realized what Lance confirms here at 7:00. Manual WDT has been mandatory ever since due to the way that the grounds are unevenly deposited into the portafilter.

[@felipeh5104]

great work here. I've been using the blind shaker cup open with wdt stir for years as I didn't like the "caking" look that the blind shake gave--seemed like it would make the problem worse. I like the story of the bottom layer in the portafilter being the most important and thus the blind shake giving the best result there. going to try that for awhile.

[@thebitterfig9903]

There’s a certain appeal to this. With as complicated as espresso machines can be with temperature and pressure profiles, as expensive it is to move to a grinder one tier up, it seems wonderful that all the faffing about with grounds and puck prep probably doesn’t matter as much as we thought. Spritz, grind, shake, tamp and go. I think I want it to be true, and so far evidence suggests it might be.

[@NutellaCrepe]

Honestly the WDT is more of a meditation tool at this point. It didn’t really do anything other than add time to my routine, but it’s always been fun to use. I’ve always had great shots with just a shake using the dosing cup.

[@Phil_OG]

Puck prep is still important... It's just that the initial distribution is already good in his experiment because of the WW magic tumbler he uses for every method before distribution.

[@AlexanderLabial]

This changes everything! Love that you really go through your methodology and that your graphs show all the data points. Guess that I have to find a blind tumbler instead of the WDT. Also a quicker step than WDT before every shot.

[@Agent002]

Great finding. Would love to see if combining the shaker and the WDT would get you better extraction in the future.

[@CoffeeNo0b0514]

Seems to not be the case when you consider the way he didn't dose direct to porta filter. WDT would like lower extraction if done after using a shaker, based on his results and what he stated in the video as it would disturb the bottom of the bed.

[@alemonalemonalemon]

I am halfway through a 1kg bag of Ethiopian light roast, stored in an atmos vacuum container, that I have been pulling using a damp paper filter, WDT and then OCD, manual tamp, mesh screen and go.

I immediately saw a slower extraction through my 18g VST basket and the cup was fuller, creamier (even with the paper filter), sweeter, the shot pulled more slowly, now I think i need to grind coarser.

@@error.418I always tap the bottom of the porta filter once, lightly, on the a silicone mat that’s sitting on my counter. Just to get the beans off the edge of my dosing funnel. Feels satisfying. I personally feel like it’s more accurate / consistent than hitting it on the side with my hand

[@error.418]

@@craigbagolphoto Oh you can mix the two, mat tap for initial settle, than side taps to even things out

[@bruinv3738]

wonder if this could work without wdt tool. hoping for one less step and one less tool

[@kenreliableb18b]

Oh man, my blind shaker is giving me the, “I told you so” look 😅😅😅

[@nalgo]

This is so, so cool! Ive had all kinds of questions for further testing floating through my head all day. A few: 1) what does the total difference in yield actually tell us? Do we think the increase in yield is an even increase (if each of these was also done as salami shots, would we see across the board increases from the shaking method)? And does this increased yield happen across the entire puck (if you cookie cuttered the pucks a la Ribes' method, would we see the increass in extraction throughout all portions of the puck)? 2) when shaking a box of granola vertically, the larger boulders are spread through the mix, but just vibrating or lightly shaking the box allows the larger pieces to move toward the top as small pieces move down. Is it appropriate to imagine coffee grounds acting similiarly? 3) with that in mind, would the results be closer/further from eachother if high uniformity burrs are used vs conical burrs? 4) I assume shaking works because it allows movement of pieces vertically through the grounds, could we employ a rotated wdt method to allow vertical movment of grounds in addition to the horizontal stirring that currently occurs? 5) with countless anecdotes of people who enjoy the taste of wdt results, is it safe to attribute that to placebo, or do we need to be looking beyond total extraction?

[@mikethemoose9733]

Hmm, shake with cup, wdt just to level the top, double tamp? I’ll give that a go, sounds simple enough.

[@pksteffen]

Gave up WDT a while back when I got a better machine and it seemed to make no difference and never looked back. Also because none of my local baristas going through all the steps YT dishes up. Might try a little shake with finicky roasts. Thanks for experimenting and sharing!

[@thelightbro6185]

I’m new to home espresso (6 months) and I kind of think that this gives me an advantage in the sense that I haven’t grown up in the hobby with the tools being gradually introduced and skewing my thoughts, they are all there in front of me now. What I’m very poorly trying to say is that common sense tells me a shake with a dosing cup and then a tap will always get the job done. I am susceptible to gimmicks in anything I try my hand at including WDT etc.

[@ebusive]

This is absolutely a breath of fresh air. Ive been going nuts trying to justify buying a 3d printer for a Umikot or just buying a Moonraker. Knowing that just SHAKING my grounds in my dosing cup will simplify my morning workflow so much. Definitely trying the shaking method first thing tomorrow morning

[@julianpark93]

It would’ve been super cool to see a combination of the blind shaker plus WDT / other distributors and compare that data!

[@vancitycanucks]

Yes can we please see this! I used just the magic tumbler with my weber key but switched to Autocomb followed by NCD and feel my shots are more consistent. But feel is different from stats.

[@MichaelBxl]

Didn't he used the grey blind shaker in ALL the techniques? See 6:43

[@thepatwalsh88]

​@@MichaelBxlI don't think he shook it in there, just dumped it. right?

[@MichaelBxl]

@@thepatwalsh88 you are right. I guess that is the most logical though it is not really clear in the video for me.

[@thepatwalsh88]

@@MichaelBxl I agree it's left a bit ambiguous.

[@0whitestone]

As someone who has not dived deep into espresso yet, this is not upsetting because it clarifies what kind of workflow and equipment I would eventually want to buy, but I can see how it could be for those who have spent tons of money on expensive gear. I would like to see some comparisons between different grinding techniques: 1)direct to portafilter 2)into dosing cup 3)into the blind shaker. I think it would be beneficial so people know the best options for their setup. I do appreciate that this is a ton of work, on top of being a dad and working a full time job, especially. I'm also liking the new video format/style!

[@charlietighe]

My brain is spinning with this lol. I used to use a dosing cup instead of pouring straight into my portafilter. However, I finally got a grinder that could hold my porta with a funnel so I no longer needed this “extra” step. The dosing cup is now used to weight the beans, into which I spray rdt before grinding. Since some water stays in the cup, I don’t want to use it to catch the grounds, at least in my current workflow. Guess it’s time to get that Loveramics dosing cup I’ve been eying 😅

[@PPGMatt]

Very interesting results! At the end of the day I think you are correct in saying that we are over doing things. Like any hobby people always seek methods to improve the process, but sometimes the best way to improve the process is to do less (remember the KISS method). This also shows that for some the goal isn’t necessarily better or improved extractions, but more as a flex to who has the most expensive tools and keeps up with the current and popular trends. Me personally, I just want the best cup of coffee possible and at the same time enjoy tinkering. 😀 Thank you for another great video, I always enjoy your content.

[@cubesandpi]

Lance I really feel like the video quality has been going way up recently. The editing has been getting a lot tighter, and you are doing a better job at continuing the video audio while cutting to b roll instead of leaving dead air. The scripts feel much more concise too!

[@kindaFunkyNGL]

These last 2 videos have absolutely killed it with the quality of data and practicality. Thanks man

[@ShinSuperSaiyajin]

We have to evenly distribute the love for coffee around the world!

[@markpalmos]

Good job Lance, always intelligent and insightful... thank you.❤

[@kubenoz]

This is a great win in terms of workflow.

[@sohailhines]

Well, direct to portafilter plus manual WDT is pretty convenient compared with having to have another vessel to now grind into. Especially if you then also use the moonraker to better distribute the top layer.

[@clarks888]

Like you said, context is key. Super interesting that maybe just shaking with the dosing cup and portafilter gets the job done, but it tends to leak fines from the basket for me (and you can see it does in the video too). I may do a little experimenting to see if I can notice an improvement that’s worth a little extra mess compared to WDT, but will be fun to try either way!

[@nichj487]

Some people in the comments are taking this new discovery as “see? We’ve been over-complicating espresso!” I think the more interesting conclusion is: the path to good espresso isn’t always intuitive or obvious. We used to think that a fast extraction was bad and that you should cut a shot off when it blonds. We thought that crema is delicious and that high brew temperatures burn the coffee. But sometimes you have to (forgive the pun) shake things up a little to make progress :)

[@davidcserjan]

Excellent Video! Time also flew by, loved the presentation and the way you made your "biases" perfectly clear as in what exactly you did and how it might affect others (grinding directly into the portafilter) differently. Great Job Lance!

[@Mark_Wood]

Mind blown, thanks Lance!

[@yannn1192]

I use a very basic setup: 1zpresso JX-pro hand grinder, 9Barista with IMS basket. After grinding I put portafilter onto the dosing cup and turn upside down, then either manual WDT for a few sec or use NCD for a couple of turns, then light tap as you did, then tamp. I didn't see much of a difference between manual WDT and the NCD but I suppose I'm not that sensitive to those nuance of tastes. I might need to further evolve my pallets to tell the difference like this, as not everyone measure their coffee scientifically in any case as long as the espresso didn't turn undrinkable. Having said that , this is a rather informative video. Thanks, man.

[@miriamaragonez8280]

I really wish you would have included the Duomo distribution tool in your testing as well

[@HadiHares-m3d]

I really appreciate you provide data and do statistical analysis. Thank you! Some further variables to consider (consistency): - Time from start Grinding to first drop in Cup (since i guess there is Time variance between each method and there are believes that within the first 30 seconds of grounded beans you lose flavor) - Partical Distribution (since each Grinding will behave a bit different, it would be interesting to keep this variable fix with i.e. separating the grounds and only using one group of particals, even though much of a clinical test and not real world test, but maybe that is the next coffee revolution 🤷🏽‍♂️) - ultimately, Taste 😂 I miss the qualitative factor (even subjective) how different methods, extraction yields effect your taste buds, since there is no evidence / correlation between higher extraction yield vs better taste.

[@FaunKeH]

14:15 was a great lightbulb moment for me. I have a Cafelat Robot and a Timemore 064s, and the dosing cup fits perfectly into the portafilter. I'll be trying this out, no needles this week.

[@m4tth3wh]

Thank you so much Lance for giving us an excellent base line to further test against. 🎉 I need to up my patreon donation. Surely you’ve more than earned it.

[@AStava]

It would be nice to see this same study run back with a direct to a portafilter. Totally understand it's antithetical to your typical process. I've been mulling over the utility of distribution methods to my process so this was intriguing data.

[@homecafecharlie]

Really interesting results, counterintuitive at first but makes sense. The bottom of the bed is critical and a quick shake works better than all the fancy tools that disrupt a simple process. Thanks for doing the testing to teach the community

[@88sstraight]

Ha, fantastic! I have done pretty much that (shake shake shake) from when I first got my Robot about 4 years ago. The beauty of that deep basket makes it possible to be pretty aggressive without excessive spillage.

[@jo.comics]

That is actually really interesting. I don't have any of the fancy equipment you're using here but I can see how I could try this with my setup for myself (if I had the time, which I don't). I have a Baratza Sette 270 and that comes with a big catch cup, so I'm curious to see if just shaking the grounds in that and then adding it to the portafilter is significantly different to WDTing as I've been doing so far. I dunno, I'd have to go by taste, really, and I don't think it'd add too much but it's definitely something to think about for myself. Thanks for the intense work, Lance, you're a legend!

[@TsvetanVR]

As a rookie in this with less than 6 months under my belt, this blew me away. I guess I don't really need to spend 150 Euros on a WDT tool then, huh? Interesting. I am still using my entry-level Smart Grinder Pro but I will definitely try to grind in a cup instead of directly into the portafilter and try to find a suitable cup to shake it before I manage to get my hands on one like yours.

[@kathleenu4461]

Using the less fancy Breville Barista Pro for 2 years. I’ve been using the Creama dosing cup with the tamper distributor combo. Doing the rituals of measuring, etc. Grinding fresh local roasted beans into the dosing cup and then attaching it to the portafiler. Keeping a firm grip on both I give it a few shakes and then use my distributor tamper to perfect my puck. My double shots are usually right on the money. I tried other tools, but this simplified combo works for me and my taste.

[@Druhue]

I have a barisa pro as well. you use the grinder? I'm going to start using your technique because I did it once upon a time when I got my crema dosing cup. I got into the WDT but yeah maybe shakey shakey then wdt just the top. I have the crema wdt and taping tool too, but I dont like the tamp on it so I do the distribution just to smooth out the top later, then tamp with a spring tamper.

[@kathleenu4461]

@@Druhue yes, I use the grinder everyday. It seems to work consistently. I’ve never used the WDT. I feel my technique works for me and the specific beans I use. If it’s not broke don’t fix it.
