Despite roasting my own beans, having a pretty good grinder (Macap M4), and machine (ECM Giotto Premium), and putting as much into my shot prep as I can imagine anyone doing, I still wasn't getting near-God shots. Until I started doing the WDT. Not only have my shots markedly improved, but so has my consistency.

Nope, never used it. My dosing is about as rudimentary as it gets. I grind while thwacking the doser to fill the portafilter, level the peak off with the back of a finger, give the portafilter three thumps onto the tamping stand to settle and level the grinds and smash it with the fancy coffee hammer.

I used to perform the WDT. I switched to a nutating move when starting to tamp with excellent results. Much faster than WDT with better results, IMHO.

When I had Rocky: Yes, I had been using it for some time. It not only dealt well with the clumping issue that this grinder creates, but fluffed up the grounds. After WDT'ing, if I leveled off across the PF gave the proper dose (leveling off caused overdosing without WDT'ing).

With Kony: No. I have found that there is no need to WDT. The grind is quite clumpless (at least when thwack-thwacking) and much fluffier than Rocky creates.

I still use the WDT even after upgrading from a Rocky doserless to a Macap M4 with a doser. Although the Macap is less clumpy than the Rocky, I still seem to get better results with the WDT. I think if I upgraded to a conical grinder or hybrid conical/flat burr grinder, I might ditch the WDT. But for now, it seems to help so I continue to use it.

Completely agree with this. I still only have a Rocky but have been playing around with sieving the coffee after grinding. To me, this seems to give a deeper, richer flavour. I still flit back to the WDT and believe that with a Rocky you cannot do without one or other, and I have tried

No. Never did. I spend a lot of time at espresso bars watching the experts grind, level and tamp. Never saw one yogurt cup. Don't expect to see one, either.

I try to encourage people to simplify their espresso making, instead of fetishizing it.

[EDIT] I know "fetish" is a provocative word, but I used it because I see the technique as one of many symptoms of a tendency of web forums to encourage ever more elaborate espresso-making rituals, most of which are useless, and some of which are even counter-productive. I am thinking of things such as weighing every shot on a gram scale, loading the hopper one shot at a time, removing and replacing the basket for each shot, cleaning out the burrs after each change of blend. Someone posted on alt.coffee this week about using a dental vibrator to redistribute the grounds in the basket.

I recognize some great espresso advances have been developed or encouraged on the Internet, and I'm not really a Luddite. I wouldn't have a PID in my machine or a Cimbali Max Hybrid on my counter, if it weren't for on-line discussions. But, I really think we let some of this stuff get out of hand.

Yes, but a professional would presumably have a good enough grinder not to need the WDT wouldn't they? It's not about fetishising it at all, it's about overcoming a flaw in a grinder. We can't all afford top-of-the-line.

I'm one of those doserless Rocky (Clumpy) users, so the WDT is second-nature. I do it w/o the yogurt cup funnel, by placing a little plastic tray beneath the PF to catch stray grounds. But by itself the WDT is not the solution to extraction problems. The Staub tamp (NSEW) is just as important in my case, because the tamper is slightly smaller than the basket.

Even with my Majors, the yoghurt cup is a handy thing. I can thwack away to my heart's content, and I don't get a kitchen dusted with black dust. Having the cup in there allows me to break up the few clumps that the major's do provide me, and an even distribution from a fairly waste-free dose. I don't have to sweep up around the grinder as much as the 'experts', don't have as much waste as they do, have far more time than they do (as any time I have a line it's a line of very eager, and very patient 'clients') and usually get at least as good a product as the 'experts' in my neighborhood.
All of the things that the pros do aren't necessarily good for the HB, and all of the things that the HB gets to/has to do aren't necessarily good for a pro environment, or necessarily necessary.
I do, however, notice a pull/taste improvement from dose-level-tamp pull to dose-WDT-level-tamp-pull, and a slight improvement with the nutating motion between level and tamp.
So, I should maybe abandon those techniques that improve the quality of my espresso because I don't see the pro's use them?

I make two doubles every morning. The first for my wife's mocha/latte. The second for a myself, straight. I definitely use the WDT for every one of my own shots - I'm much more consistent that way. But I like practicing without it on my wife's shots (she can't taste the difference with all that chocolate, anyway), to see if I can get a decent pull without doing it. If I get good enough, I'll abandon the WDT. But right now, can't live without it.

I've got a NS Grinta grinder which gives fantastically consistent grind albeit kinda clumpy. I just use a table knife to push the grinds around as they fall into the basket. When I'm done I bust up the large clumps but nothing too meticulous. I smack the side of the PF with the palm of my hand to get things even and settled. I tamp once then bang around the edge of the PF with my tamper a few times to make the grinds that have "walled" up the side of the basket fall down. Then I tamp lightly again with a twist. I don't really know the details of any particular technique, this is just what I've come up with myself based on what feels right and what works. I tend to pull shots based on blonding rather than any set time which I think levels the playing field a bit. Usually my shots will blond around 25-30 seconds and occasionally they'll take much longer, sometimes close to 50 seconds! As long as I use blonding as the shutoff guide they all taste pretty damn good! I actually enjoy the subtle variations.

Yeah I agree with that, I've gone through som crazy rituals myself in the past, most of which as you say were pointless/detrimental. I can only talk from my own experience, which as a "home-barista" is only a year or so, but in back-to-back shots with/without WDT or equivalant on my setup the result is the same: using WDT produces better coffee in the cup.

If I had a better or professional grinder that did not produced clumped-up coffee, I doubt I'd do anything different to you. But I do believe that for grinders that produce clumps the WDT produces obvious improvements in the cup.

I used to use the WDT when I first started - it helped a great deal. After I got used to dosing evenly and tamping level I started using the Stockfleth move. Been doing it that way ever since. Much faster.

I agree with Marshall.

I've been using the stockfleth's move for some years (long before somebody named it that way) with different grinders, doser and doserless, and never felt the need of using any other distribution technique.
If you use that simple (and fast) technique, clumps do not usually affect the result in the cup.
That's my experience at least!

No...my grinder choice was made to avoid it, and that has worked as hoped.

Yes, I use the WDT method since I use a Rocky doserless. I use a really short yogurt cup (maybe less than an inch tall), so it fits in the basket and under the spout without having to remove the portafilter holder. I find it's really simple and quick and also helps keep my kitchen counter a little cleaner.

If you have a good grinder and machine, I think all these techniques get debunked when you watch the WBC Champions use simple techniques. Look at Heather Perry and her simple technique. Or Matt Riddle and his simple technique. If they can perform at that level, providing a top of the class taste experience for expert tasting judges, then it's good enough for me. It makes me feel a little silly to go through anything more complicated than that if the best of the best are doing fine without it.

Also, consider that they developed their blends using those techniques, so it probably taste great that way. Of course, it helps to have a good grinder. A used Super Jolly can be found pretty cheap. I found a Rio Normale for $365.

I use a moderate "thwacking" technique during dosing and a very simple NSEW, a light leveling tamp, then a harder tamp with a twist and then blow off the loose grounds into the sink. My sink happens to be right next to the machine. It's very quick and has provided consistently good results.

As a newbie, the WDT seems a bit complicated, needles, yoghurt pots cut to size etc.

Why not just use an ordinary fork in the portafilter?

Alternatively, why not dose into a cup, shake or stir as vigorously as needed, and decant into portafilter?
