I suppose it's been by osmosis but my home technique (with Super Jolly) has evolved to the following:


    * Keep hopper filled with at least 1/4 lb to 1/2 lb of beans - about a three day supply. If I expect to be away from home for a few days I empty the hopper into an airtight container. I no longer weigh the dose. An old Time-O-Lite darkroom timer gives me a timed grind and 8 to 9 seconds always gives me about the right dose.

    * Use rapid multiple pulls of the doser lever and tap the portafilter on the forks gently a few times while dosing

    * Stockfleth type distribution - I tried the chopstick, the spatula and few other flat edge items but I don't see the benefit in a home environment. I do believe there's an advantage in a commercial setting if one is trying to achieve a standard of consistency for distribution when a variety of barista's with differing techniques are rotating in and out in one location.


If I recall correctly... Intelligentsia has the front line crew in their shops using a metal blade of sorts for distribution (some type of bottle opener which consists of a flat metal blade).

Yes, the so-called "Chicago Chop" (from Home barista techniques that the pros shun):

I think someone on CG coined that phrase a while ago. We started using that when we switched over from the swift about 3 years ago, now. We needed to come up with something that was ultimately repeatable for the baristas. Since there are sometimes upwards of 6 people working at once, we needed something that wouldn't take the "art" out of making shots, but was still able to be used by more than one person on a shift without the lag time of changing the grind every time someone went on break. Enter the chop.

As for competition, none of us use the chop method. We have all developed our own techniques for distribution and leveling... (cont'd)

I noticed that Counter Culture includes the same technique in their training.

I have tried the "Chicago Chop" at home and found it far more successful with a flat edge metal blade than with a chopstick. But I still found myself underdosing - or so it appeared. I wasn't getting as consistent a distribution as I get from using my finger (this assumption based on watching the bottomless PF).

No reason to change if this works well for you. We're all different and I never could get Stockfleth's or the likes to work for me. I'm likely several inches taller than most here with big hands. Wandering from the OP but I was in a shop several months ago (name changed to protect the innocent) where the barista had a cold. He coughed into his right hand and then wiped his runny nose before doing a Stockfleth's on my shot. I wasn't sure I wanted to drink the resulting beverage he served me or not... :roll:

The C. Chop is my personal favorite approach. The first time I saw the chop in action was at a convention where one of the Josuma guys was using a popsicle stick for this. I overdose the basket a little from the doser, chop, chop, chop back and forth in a NSEW pattern, swipe, swipe, swipe the basket level with the straight edge (I use a silicon spatula as it's quieter than a metal straight edge) and away we go. I did find that I ended up grinding a notch or two finer using this technique than with a finger method- On track with the OP, I abandoned the WDT when I moved to my Kony as it didn't seem to need it vs. my DL Mazzer.

At the caffe I use a Stockfleth's type distribution method and then level off with the doser lid. Most important part from my experience is 1) keeping grinder burrs clean&sharp 2) HOW the grinds fall into the basket Of course when your done, tamping level is a good plus.

Over the past week I have stopped everything in regard to distribution. I was dosing into my portafilter one day and stood there looking at the nice neat and clump free mound in my basket and thought 'I wonder what would happen if I just smashed it flat with my fancy hammer'. So I did, half expecting a sink shot. To my surprise I pulled a very good shot. I have kept with the dose in the basket and squash it technique for a week with no ill effects. In fact, I think my shots are just as good, or better than normal possibly due to minimal fussing with the dose.

So.... this means you have really really good aim and a hammer with a 57 mm diameter head? :wink: My neighbor watched me hammering on a carpentry project once and said I worked like lightning - almost never hit the same spot twice :o

I will have to try grinding finer and using the chop again. My hands are also big but my fingers aren't especially long (thank goodness I'm as handsome as a movie star and don't have to work with my hands :wink: ) The only easy way to do the Stockfleth's for me is to use my pinky. Maybe that's my problem. But the fact is that I use a Swift at my part time job (not my choice) and only grind and tamp six or eight shots per week just at home on the weekends.

Another possible benefit of "fines migration", assuming that it occurs:

Water pushes through the puck from top to bottom, so you could conclude that during the full course of the shot, the fines that make up the bottom layer of the puck are less extracted than the coarser grinds of the top layer. Considering that it takes about 8 seconds for the first drop of liquid to make it from the dispersion screen to the cup, that might be a significant effect.


I've been using a toothpick to stir the grinds coming out of my Mazzer Mini for the past few days. No yogurt cup, but since I don't usually updose, my hand easily prevents spill-over. The added step has definitely improved shot quality.

THANK YOU MR WEISS!

I have tried it for the first time last night and it is amazing how it made the whole espresso process much more forgiving especially on the finicky Miss Silvia. Other people can call it a cheat but I think it is more of a solution.

I believe if new beginners knew about this process, the learning curve to making espresso would be much easier.

The only thing that bothers me is having invested so much money in espresso equipment I wish I could find something a little more classier looking than a plastic cup

Though it has been mentioned in this thread, I have to reiterate: the "ideal" technique will and should vary based on equipment used (especially the grinder).

In theory, a grinder should be able to deliver a perfectly even (3-dimensional particle distribution) puck of ground coffee, perhaps in a "shower" similar to those "rainshower" bathtub shower-heads, with minimal oxidization/air-mixing, ready for tamping. No such grinder exists, and no such grinder is on the horizon. So, we manage the design-flaws (if you can call them that) and figure out techniques and tricks.

I have my dosing/distribution technique, which (on a Mazzer grinder/doser) is to insert the portafilter in the forks at a "9-o'clock" position, and then rotate the portafilter ONLY after that particular edge of the portafilter basket has filled up. Then I rotate slowly to fill in the rest of the portafilter. Three fork-taps, then a simple forward-back-forward level (on a single axis). Usually, my final stroke will somewhat "round" off the top, controlling my up-dose.

I tried the WDT last year, and it is definitely a good idea for clumpy doses. However, good/proper dosing technique will render the WDT unnecessary; but that's on my (pro) equipment.

A good training technique (if you have enough coffee to burn through) is to grind and dose and tamp (as Luca mentioned in the second post in this thread... were you serious?), withOUT any distribution or leveling. It forces you to improve your dosing, as the distribution/leveling isn't available to help you fix your dosing flaws. Dosing should (ideally) be perfected. Distribution and leveling shouldn't be relied upon forever as a "fix" for poor dosing. They should be the final "polish" of the technique, indeed to help maintain consistency and quality, but the key word is "maintain." It helps maintain the integrity of your dose. It can't really create a good puck. It's like using too much body-filler/bondo on a car body: body-filler is for small holes or dings, not for creating the shape of the car body.

Work on your dosing... that's the single most effective technique to improve espresso quality (again: in my opinion).

All that said, having spent a little time on home equipment, some grinders are simply clumpy, especially the earlier-in-this-thread doserless versions. WDT can help.

I'm a furious doser. I rock that thing hard and fast. I'm trying to keep it under control as I prepare to compete at the US Barista Championship, to keep from being so messy. That said, it's been of growing interest to me that though we baristas use the grinder-dosers in ways that they were never designed to, the best overall design (for in-basket grind quality and distribution) that's emerged so far is still the grinder-doser.

Anyone considering a doserless grinder should watch the WDT ritual and decide whether the "convenience" of a doserless or avoidance of a gram of the previous shot's grind is worth it. I think the innovation of the doserless espresso grinder is a great example of "beware what you ask for, you might get it."

good point, Marshall- but maybe the best in doserless technology may still be waiting out there somewhere. I just don't think they've created it because the demand hasn't created the right atmosphere of economic interest for grinder manufacturers to make something better for the home user. In the end it's probably no big deal to vacuum old grinds out of the doser (I do this daily w/ my Kony- and it only takes a few seconds using a $30 shop-vac. I just can't help thinking that all the crazy efficiency-minded stuff this machine came bundled with (eg. auto shut-off when the doser fills [yeah, right], and auto turn-on when it senses the doser is nearing empty [huh?] when I only grind for me and my wife 99% of the time). It's understandable- supply vs. demand, all I can hope for is that enough folks like me demand it and it'll be developed, marketed, and eventually the price will be reasonable for many home users and the WDT will be a thing of the past. I can still dream, right? Problem is: I'll probably die long before the Kony does!

It's still one of the best hobbies (if not safest, compared to bike racing) you can have.

I have recently joined Home-Barista forum but have been reading it regularly. The topic of this discussion intersects with the one on CG where I posted my discovery of the new Weiss distribution device.

I will be glad if some one else find it helpful.

Marshall, you've been in the biz a lot longer than I have, and I have a great deal of respect for your opinions on all things coffee. But if this post means what I think it means, then I beg to differ. Doserless grinders make perfect sense for the home barista, and some of the most highly regarded espresso grinders for home use are doserless (such as the Mazzer Mini E and the Versalab M3). Furthermore, there is very little "ritual" associated with the WDT, and your comments lead me to wonder whether you've ever given it a try.

In the spirit of Dan's Latte Art Challenge(d) thread, here's a walk-up WDT video from tonight. One take, no editing, no do-overs:


If your dose/distribute/tamp regimen is significantly faster and easier, I'll eat the puck. :twisted:

Here's the resulting pour:


OK, the grind needs to be loosened up a tad. But this is a typical WDT result: a nice even extraction resulting in a very tasty shot.

One day someone will produce a grinder that distributes clump-free grounds evenly into the filter basket every time, is appropriately sized for the home kitchen, and is reasonably affordable. But until that day comes, I believe the WDT is a very useful technique for the home barista.

I'm "in the biz" only as a lawyer, writer (on legal matters) and volunteer. So, don't confuse my being opinionated with being an expert. :D

As a simple matter of time comparison, the doserless/WDT takes at least two or three times as long to dose. My Mazzer is on a timer. So, I know I take 12 seconds to grind and dose and 3 or 4 more to level. I also don't have to remove and replace the basket in the portafilter, another thing that no professional does.

But, my objection to the doserless/WDT goes further than that. It's also esthetic and philosphical. I think it's a symptom of the tendency of hobbyists to obsess over brewing techniques and develop ever more elaborate and unnecessary rituals to perform simple tasks. It turns a simple pleasure into a choreographed ceremony. Plus those yogurt cups look like hell next to a beautiful espressso machine.

Italian baristas get great, consistent results with a flick of the doser and a simple "up motion" on the built-in tamper. My friend, Angelo, at EspressoPartsSource does this all the time, while cackling about the silly rituals that Americans enjoy (he means mine).

Looking at the video, you'll see that grinding/dosing takes me about the same amount of time, and so does leveling. The WDT protocol adds perhaps 5 extra seconds, time that is partially regained in reduced cleanup. I don't see the 2-3X time factor that you claim. I'm happy to spend an extra few seconds to ensure an evenly distributed bed of grounds for tamping.

Marshall wrote:I also don't have to remove and replace the basket in the portafilter, another thing that no professional does.

I'm not a professional either, and it doesn't bother me to use different equipment and techniques at home than in a coffee shop. Commercial grinders, with 1kg bean hoppers and large dosers, perform reasonably well in a commercial setting. They are not nearly as well suited for the needs of the home barista. I don't have to dose directly into the filter basket and then slip it into the PF (a step that adds at most a second), I choose to do so. I also choose to use a ridgeless basket, bottomless portafilter, and doserless grinder, items you don't see in most commercial settings. This has nothing whatsoever to do with the WDT.

Marshall wrote:But, my objection to the doserless/WDT goes further than that. It's also esthetic and philosphical.

Ah, now we get to the nitty gritty. It's certainly your privilege to object on aesthetic and philosophical grounds. Personally, I regard this as a technical issue. If something can help me achieve a better pour with a modicum of cost and effort, I'm going to give it a try. If it works, I'm going to use it. You can argue the philosophy of dosers and grinds distribution all you want. I'm much more interested in the results in the cup.

I did not include grind time, which is dependent upon the grinder. There is nothing to prevent you from using your favorite leveling technique (Stockfleth's etc.) with the WDT. The WDT only adds about 5 seconds to your prep time. And once again, I'm not advocating it in commercial settings (as seen in the first two videos).

BTW, I see you have a posted an instructional video on vac pot brewing, in which you advocate stirring the grounds with a whisk. I suppose that's OK though... :roll:

Crikey! I'd hate to get one of your bills it that's an example of how you calculate time! Do lawyers get special watches when they pass the bar? :lol:

The reason for going doserless is to avoid the bloody "Thwack"Thwack"Thwack"Thwack" :evil:

After trying the WDT for several months, I abandoned it as it appears to give no improvement. I tried several variations : Concentric circles, small circles, back and forth, inward, outward spiral. :?

My impression is that grinding half a shot into the bin on the first shot of the day and discarding the first couple of seconds of subsequent shots achieves better consistency. A gently side to side shake of the PF, down dose and a gentle tamp yields great consistent espresso. If I bother to use the BPF, the pour starts, tiger stripes and finally lightens evenly across the basket. What more could I want? 8)
