The pursuit of extracting the “absolute best” coffee has been an obsession for lots of baristas and avid domestic brewers for a while now. Variables like dose, yield, time, and grind measurement at the moment are regularly thought to be the fundamentals, with components reminiscent of power profiling and temperature changing into an increasing number of prioritised.
Competitions – particularly the International Barista Championship – have for sure performed an enormous function within the wider business’s fascination with coffee preparation. One of the notable festival tendencies lately has been distribution gear, particularly the Weiss Distribution Methodology. On the 2022 version, winner Anthony Douglas debuted the Barista Hustle Autocomb at the WBC level, which indubitably stuck the eye of the area of expertise espresso group.
Since then, many different competition have adopted in Anthony’s footsteps and used the Autocomb of their routines, together with 2024 International Barista Champion Mikael Jasin. Concurrently, we have now observed a number of complicated distribution gear introduced available on the market that experience additionally been broadly embraced via the business – indicating that area of expertise espresso’s obsession with WDT stays robust.
To determine extra, I spoke to Dr. Robert McKeon Aloe, unbiased espresso researcher and writer, and Anthony Douglas, 2022 International Barista Champion and Analysis & Construction lead at Axil Espresso Roasters.

Why distribution is necessary for very good coffee
Sooner than we discover the new string of latest Weiss Distribution Methodology gear available on the market, it’s necessary to elucidate what it’s precisely. Advanced via John Weiss in 2005, the process comes to stirring flooring espresso in a portafilter basket the usage of a high quality needle or an identical utensil.
There also are various different distribution ways, together with:
- Facet faucet and settle – merely faucet the portafilter again and again together with your hand to get a divorce any clumps after which gently faucet on a fair floor or your hand to flatten the grounds
- NSEW – position your finger around the most sensible of the basket and push the grounds away out of your frame prior to pushing them again against you
- Stockfleth – very similar to the NSEW way, however you additionally wish to rotate the portafilter and your hand in reverse instructions
- Dosing cup – grind espresso right into a dosing cup, shake, after which pour into the portafilter basket
So why is distribution so necessary for excellent coffee extraction? Dr. Robert McKeon Aloe, unbiased espresso researcher and writer of Engineering Higher Coffee and Complicated Coffee, explains why.
“While you grind espresso, the particle distribution adjustments, as does the form of the espresso grounds,” he tells me. “This creates a number of other layers within the basket, which would possibly not all the time be perfect for even espresso extraction.
“The use of an coffee distribution instrument is helping homogenise the bottom espresso right through the portafilter basket, and in principle, will have to assist extract a greater shot,” he provides. “To be had information from exams performed with and with out distribution range in keeping with the distribution instrument used. The one instrument that turns out to assist extraction potency is a WDT instrument, and maximum were home-made till just lately.”
The hot development of complicated WDT gear
On the 2022 International Barista Championship, we watched as Australian competitor Anthony Douglas used a handbook coffee distribution instrument we had by no means observed prior to – the Barista Hustle Autocomb.
The instrument is composed of a mount, 12 skinny needles, and a care for that you simply spin to transport the needles round. Merely put, the area of expertise espresso business had by no means encountered such a sophisticated WDT instrument.
“The Autocomb used to be a large access into the marketplace,” Robert says. “It’s a device particularly designed for industrial use and fast distribution. In the similar yr, the Weber Workshops’ Moonraker introduced, which is extra interested in design and is in large part focused at domestic baristas.”
Impressed via Swiss watch design, the Moonraker is certainly an overly visually interesting WDT instrument, with “completely calculated spirographic motion” in line with Weber’s website online. Maximum just lately, automatic tamping resolution PUQPress introduced the Navigator instrument. Whilst we don’t know a lot details about the brand new product, the corporate says it “utilises randomness” to calmly distribute grounds, and seems to be the primary automatic WDT instrument to be had available on the market.
Coffee distribution indubitably isn’t a brand new thought, but it surely’s transparent that the marketplace for extra complicated gear and gear is rising.
Along with being the 2022 International Barista Champion, Anthony Douglas is the Analysis & Construction lead at Axil Espresso Roasters.
“We’re for sure seeing much more hobby in WDT gear,” he says. “Handbook WDT gear have all the time been in style in the house espresso group, however no longer somewhat such a lot at the festival level or in espresso stores, in large part as a result of the usage of them is extra time-consuming.”
On the 2024 International Barista Championship, 5 of the seven finalists used the Autocomb of their routines. The 2 last competition extensively utilized a unique form of distribution instrument, so coffee distribution has obviously made its mark on the festival.
“Extra competition will glance to earlier finalists for inspiration or new ways and inventions they may be able to use in their very own routines,” Anthony tells me. “After showcasing an previous iteration of Barista Hustle’s Autocomb in my profitable 2022 WBC efficiency, it used to be in reality thrilling to look it utilized by various competition the next yr, and much more so this yr.
“I feel the usage of the Autocomb to win the 2022 International Barista Championship indubitably helped top hobby in WDT gear,” he provides. “However in the end, the good fortune of those merchandise lies in the truth that they just make higher coffee, while additionally maximising workflow and repeatability.”
However will hobby prolong past competitions?
WDT gear have develop into a staple of the WBC, and we’re prone to see increasingly competition use them. However like different rising tendencies on the match – assume showcasing uncommon espresso species or the usage of freeze-distilled milk – will in addition they take off within the wider business?
“Many espresso stores already use some more or less distribution methodology,” Robert says. “Different distribution gear also are quite common, no longer simply WDT. I believe those will slowly substitute what’s already on bar, particularly if they may be able to be simply built-in just like the PUQ Navigator instrument.”
He provides that the extra individuals who use those units, the extra we will support our figuring out of extraction.
“The thrill phase is that extra other people can collect information about their coffee preparation ways,” Robert says. “Lance Hedrick accrued numerous information the usage of many various gear, together with Weber Workshops’ Blind Shaker. In his exams, he discovered that the Blind Shaker outperformed all different gear, whilst maximum didn’t support extraction yield.
“This learn about didn’t come with style as a deciding issue, which everybody will level to as being king, however style does have a free correlation to extraction yield,” he provides.
Developments regularly come and cross in area of expertise espresso, however coffee distribution gear are right here to stick. If truth be told, we will be expecting to look much more of them in high-end espresso stores and competitions within the coming years.
Whilst consistency is necessary for very good coffee, potency and workflow also are necessary. Having a look forward, it’s most probably that WDT instrument producers will stay this in thoughts when designing their merchandise.
