There are lots of variables to imagine when pulling coffee pictures, which come with dose, yield, extraction time, and grind measurement. In addition to those, we additionally want to needless to say puck preparation ways – together with distribution and tamping – are similarly necessary.
Necessarily, excellent distribution and tamping ways assist you to to succeed in even extraction and permit you to get the most efficient from your espresso.
All the way through his profitable 2022 Global Barista Championship (WBC) regimen, we noticed Australian competitor Anthony Douglas use a number of distribution and tamping equipment sooner than he pulled his coffee pictures. One in all his equipment used to be specifically designed to hold out a distribution manner referred to as the Weiss Distribution Method (WDT).
So what’s this method, and why did Anthony use it in his regimen? Additionally, must extra espresso stores be the use of those distribution and tamping strategies, too?
I spoke to Anthony to determine additional information – learn on to determine what he mentioned.

What’s the Weiss Distribution Method and why is it used?
Ahead of we talk about the WDT, in addition to different an identical strategies, we first want to perceive why distribution is so necessary.
To be able to pull fine quality coffee pictures, espresso must be flooring very positive to extend the skin space of the debris. It’s because coffee is extracted over an excessively quick time period the use of high-pressure water – this means that you’ve got a smaller window to extract fascinating flavours and aromas compared to filter out brewing strategies.
Moreover, for the reason that grind measurement for coffee is so positive, it will occasionally result in clumping. That is when flooring espresso sticks in combination, which is able to purpose a lot of issues all the way through extraction, equivalent to channelling.
In espresso stores all over the world, there are a variety of ways in which baristas can distribute grounds in a portafilter sooner than extracting the espresso as coffee.
Some of the not unusual strategies is to easily “faucet” the basket of the portafilter towards your hand or the skin of the counter. You wish to have to copy this till all of the clumps damage down and the grounds are flippantly disbursed right through the basket.
This distribution method is by way of a long way the best one – particularly all the way through busy classes – but it surely doesn’t at all times produce the most efficient effects.
The WDT, in the meantime, calls for you to make use of a positive needle or an identical utensil to stir the espresso grounds within the portafilter basket. Maximum WDT equipment have round 5 needles, which lend a hand to wreck down clumps and create a good density of flooring espresso.
The WDT used to be evolved by way of John Weiss in 2005 after he discovered that some house grinders led to espresso to clump in particular badly. Since then, many baristas and low fanatics have followed the method.
You’ll additionally position a funnel over the portafilter basket when the use of the WDT to make sure to comprise all of the espresso grounds whilst you stir them – another way your dose might be too small.
In his 2022 WBC regimen, Anthony used a WDT software which isn’t recently commercially to be had. This instrument (evolved by way of Barista Hustle) is fastened on most sensible of the portafilter and reduced down in order that its needles run thru all the intensity of the basket. Then you spin the maintain of the software to take away any clumps and flippantly distribute the grounds.
Anthony, who may be the educational supervisor at Axil Espresso Roasters, explains why he used this particular WDT software.
“All the way through my 2022 Australian Barista Championship regimen, I used considered one of Barista Hustle’s handbook WDT equipment,” he says. “It produced great-tasting coffee, however Matt Perger [the founder of Barista Hustle] used to be sat within the target audience.
“After the contest, Matt approached me and requested if I would really like to take a look at a brand new WDT software that they have been growing,” he provides. “I then used this WDT software on level on the 2022 WBC.”
How efficient is the Weiss Distribution Method?
Anthony believes that the WDT is probably the greatest distribution manner for baristas to make use of.
“It’s the most efficient distribution manner that I’ve used as it’s the one method that flippantly distributes flooring espresso from most sensible to backside, in addition to aspect to aspect,” he explains. “In flip, I’ve skilled the most efficient effects with this technique.”
So are there sure procedures you must observe when the use of the Weiss Distribution Way to get the most efficient effects?
Originally, we want to imagine which form of software you might be the use of – in particular the dimensions and duration of the needles. Preferably, the needles want to be skinny, however now not too skinny that they might damage because of heavy use. Some execs suggest the use of needles which can be no wider than 1mm to verify grounds are disbursed flippantly.
Additionally, all needles must be capable of achieve the ground of the portafilter basket in order that they may be able to flippantly distribute flooring espresso right through all the basket. If the needles aren’t lengthy sufficient, as an example, handiest the skin of the puck will likely be disbursed, which might result in channelling or different problems.
Anthony explains that the needles of the WDT software he used within the 2022 WBC have been spaced in some way which supposed they disbursed all the floor space of the basket in a single spin. In the long run, he says this helped him to extract a repeatable and constant flavour profile, with blackberry as one of the crucial outstanding tasting notes.
“They lend a hand to ‘fluff’ up the bottom espresso extra, this means that that it’s more straightforward to distribute the grounds,” he tells me. “It’s because the extra compact the grounds are [before tamping], the tougher it’s to distribute them.”
All the way through his 2022 WBC regimen, Anthony additionally spun his WDT software for slightly below ten seconds, which he says is helping to lead to extra even distribution, too.
Alternatively, when wearing out the WDT, it’s imaginable to overstir the grounds or distribute too aggressively. In the long run, you must at all times stir the grounds in a cautious and regulated means to succeed in the most efficient effects.
What about tamping?
In addition to distribution, it’s additionally necessary that we imagine tamping ways.
In easy phrases, tamping is whilst you observe power to flooring espresso in a portafilter basket, which makes the puck compact.
Alternatively, in case you tamp inconsistently disbursed espresso, you’ll be able to create an asymmetric puck. In flip, it will negatively impact your coffee extraction.
Understanding how a lot power to use whilst you tamp is necessary, however you additionally want to issue within the form of the tamper you might be the use of. There may be all kinds of tampers to be had – together with convex, flat, calibrated, or even automatic tampers.
Lately, we now have additionally noticed the emergence of height-adjustable levelling tampers, such because the Nucleus Espresso Distribution software which used to be designed by way of 2015 Global Barista Champion Sasa Sestic. Most of these tampers have angled slopes as a substitute of a flat base, which is helping to transport flooring espresso in a round movement, thereby making improvements to the evenness of the puck
Regardless of which form of tamper you utilize, one of the crucial necessary issues is to make certain that your tamper suits snugly into the portafilter basket. Many espresso execs suggest the use of a tamper this is round 0.3mm smaller in diameter than a portafilter basket.
It’s because if the tamper is simply too small, you gained’t be capable of flippantly tamp all the puck. Conversely, if the tamper is simply too giant, you might want to possibility getting the tamper caught within the portafilter and demanding the espresso puck.
In his profitable WBC regimen, Anthony used a two-step tamping procedure for all of his drinks – he first used a levelling tamper sooner than the use of a Nice Leveller spring-loaded tamper.
“The outer rim of the calibrated tamper I utilized in my regimen is 58.5mm in diameter, so it sits at the fringe of the portafilter basket,” Anthony says. “As it’s spring loaded, it approach you push down at the maintain and the bottom of the tamper is going into the basket to compress the espresso grounds.
“It is helping to handle a degree tamp, so there’s no method that you’ll be able to tamp inconsistently,” he provides.
Anthony says he want to see extra baristas the use of the WDT in espresso stores.
“Baristas must know the way to tamp correctly within the first position, however the use of the WDT additionally is helping to make stronger consistency,” he explains.
In the long run, if performed appropriately, the use of the WDT would permit baristas to succeed in extra even extraction, and due to this fact serve better-quality drinks.
“If you happen to’re doing the WDT manually, it may be tricky to do it with each drink you are making, so possibly it might be used for costlier coffees,” he provides. “However in case you use a WDT software like the only I used on the 2022 WBC, it may be a lot sooner and more straightforward.”
On a an identical notice, the expanding collection of automatic tampers in espresso stores implies that tamping may also be a extra environment friendly procedure, particularly all the way through busier classes.
“In my revel in, I recover effects with handbook tamping, but when I’m running at the back of a hectic bar, an automated tamper just like the PUQpress would lend a hand to make stronger my workflow,” Anthony explains.
There are lots of necessary steps to imagine when getting ready fine quality coffee, together with distribution and tamping. Alternatively, whilst you distribute and tamp your puck appropriately, you’ll be able to extract espresso extra flippantly and finally end up with better-tasting effects.
And whilst tamping is a not unusual follow within the overwhelming majority of espresso stores, the WDT is indisputably much less common. Alternatively, whether or not or now not this technique will likely be used extra extensively by way of baristas continues to be noticed.
