If you’re a fan of the French press, but not the fine particles that cloud your brew, the Espro Press is about to change your morning cup for the better. The Espro is a press pot that uses a dual micro-filter that’s 9 to 12 times finer than the mesh on a standard press. I first encountered the Espro Press at the Houston Specialty Coffee Event nearly 2 years ago, where I enjoyed a cup of Yirgacheffe from 49th Parallel. I was quite surprised by its cleanliness and depth of flavor, but believed I had “matured” beyond such methods.
It wasn’t until a visit to Coffee Collective in Copenhagen last year that I was encouraged to give it another look. When I saw the Espro being used on bar at Coffee Collective and after thoroughly enjoying a cup of Esmeralda Gesha from it, I realized the press pot had been reborn—renewing my enthusiasm for a faithful old brew method.
A year ago, Espro launched a Kickstarter to fund the production of a large 30oz Espro Press—raising over $80,000—to complement its original 8oz version. This week, the Vancouver, Canada-based company is back on the crowd-funding site for help producing a new 18oz size press, which not only offers a more practical size, but will also include a few design refinements over its small and large counterparts.
The French press is one of the most common ways for people to brew their coffee at home. It was the method I first used to brew at home and it’s even the most popular way to brew among Verve Coffee employees. At one point in time, it was a preferred method of brewing coffee in some of the great specialty coffee shops before the pour over craze converted many of us to the pleasure of sweetness and clarity that paper filters provide.
While the full immersion brew method and simplicity of the French press are great, its muddiness and grit can mask and distort some of the more nuanced flavors in coffee, which is why you may have noticed them disappearing from some of your favorite cafés. But their ease of use and the ability to brew large quantities for guests is nearly unrivaled by most home brewing methods. Espro takes advantage of those positive aspects and has done a great job addressing the negatives with their redesigned filter.
The Espro filter system is comprised of two (BPA-free) plastic frames that are wrapped with a micro-mesh and nest comfortably into each other, creating twice the filtering of a standard press. The filter then screws onto a plunging rod like other press pots so it can be unscrewed and cleaned once you’re finished. The pot itself is polished, double-wall stainless steel, which keeps things warmer longer, although I highly suggest decanting the coffee immediately after brewing to prevent over extraction (bitterness).
The filter system is a remarkable improvement over the standard French press and it’s surprising that it took so long for someone to accomplish something that seems a bit obvious. There is however one issue I have with the large size press that Espro sent me for testing—which the company says they addressed in the design of the new medium size Espro—and that’s the retention of coffee below the filter cup. Since the current filter system fits so well into the pot, and there are no holes in the bottom of it, the Espro traps a substantial amount of coffee at the bottom that ultimately goes to waste.
When brewing 750g of water in the Espro, I decanted 554g of coffee. After “rocking” the pot back and forth, the total increased to 568g of coffee. With the Bodum press however, I brewed 750g of water and was able to decant 674g of coffee—giving me another half cup of coffee. You can squeeze a bit more coffee from the Espro by slightly raising the filter or continuing to rock it back and forth, but this also risks increasing the amount of sediment that passes through, which defeats the entire purpose of the product.
Below I’ve run an experiment to illustrate the difference between the sediment in the Espro compared with a standard Bodum French press.
I brewed coffee with each press using the same parameters and technique: 45 grams of coffee to 750 grams of water (coarse grind, 8-A on a Baratza Vario-W), a 2 minute steep followed by a stir, followed by 2 more minutes of steeping and a controlled 30 second press. The coffee was immediately decanted to prevent further extraction. I then poured the decanted coffee through a rinsed V60 paper to capture the sediment and give a visual approximation of the differences.
Overall, the coffee brewed in the Espro had more sweetness, more clarity and more acidity than in the standard French press. The resulting cup was not entirely sediment free, but it was reduced to a small bit of mud from fines rather than a gritty mouthfeel throughout. Depending on variations in your method (i.e. the cupping method of skimming before pressing) it’s possible to further reduce the sediment.
My goal with this test was to replicate a more standard use of the press pot than to examine the most effective sediment reduction methods. I found the amount of sediment from the Espro to be similar to what you can achieve with the Able Kone, but with the approachability that a press pot offers to beginners who are looking for a less intimidating way to start brewing much better coffee at home.

There’s a new coffee brewer vying for attention on the internet, but without an $11,000 price tag, this one has received much less fanfare. The Impress, a stainless steel AeroPress-like contraption, is the latest coffee product to raise production costs through pre-orders on Kickstarter. The campaign will have most likely reached its $50,000 goal by the time you read this post—with 25 days remaining.
This latest attempt to improve how we brew coffee comes from Raleigh-based Gamil Design. The husband and wife led design team have taken elements from several brew methods to create a simple and streamlined product with curiosity inducing potential.
The primary concept is based on full immersion brewers like the French press and Eva Solo—pour in hot water, ground coffee and steep—but the Impress utilizes a new way of separating the grounds from the water. It uses a plunger like contraption resembling one from an AeroPress, with an inverted portafilter basket attached to the bottom. After the proper amount of time has passed (3-4 min), pushing down on the plunger will draw the coffee through the microfilter, while trapping the grounds at the bottom.
The tight seal of the plunger combined with the more precise holes in the metal filter, are designed to allow far less sediment through than a French press (an AeroPress using a Disk filter comes to mind). Once the plunger has been pressed all the way down, the Impress becomes a 12oz travel mug that carries your freshly brewed coffee.
While my immediate thought was the over extraction that would occur from continuous steeping, the designers claim that it’s virtually nonexistent because of a much more prominent barrier created between the coffee and extracted grounds than what you find in a French press—if nothing else, the affect is most likely reduced a fair amount.
The double-walled exterior, combined with the steel plunger create 3 walls of insulation that’s sure to keep your coffee temperature stable and offers an attractive new coffee brewing option for traveling and camping (although its current design can’t be used to boil water). The designers experimented with a version that worked with interchangeable filter baskets, including VST baskets, but ultimately decided to use a proprietary filter design that screws in place for added durability while plunging.
Without having tested the Impress, it’s hard to say how well it brews a cup of coffee, but the idea was intriguing enough to support and I look forward to giving it a try.
What’s priced like a Clover ($11,111), designed like an industrial-chic home espresso machine, and works like a manual Trifecta? The Blossom One—I think.
This quirky looking prototype has been making the rounds at cafés, offices, and trade shows for several months to demonstrate its current version—Dev2. While actual photos are limited on their website, the technical drawings illustrate several brewing concepts mashed together to create, in their words, “better brewing through technology.”
Coffee is brewed by first pouring filtered water into the reservoir and loading ground beans into the standard espresso portafilter (but not tamping). Next a brew profile is selected from a list of presets or programmed in using manual mode. Then the machine comes to life, a portioned volume of water is pumped into the boiler and heated to the required temperature. The system then pauses to allow the user to get ready to brew. On the user’s command hot water is dispensed into the brew chamber with attached portafilter. At this point electric heaters in the brew chamber take over. The chamber adds heat to the brewing coffee to maintain a constant temperature. The brewing coffee is stirred manually. After the specified brew duration, the machine beeps to alert the user that it is time to dispense the coffee. The outlet valve is opened by the user and the plunger is pulled to force the coffee out into a cup. The spent grounds are left in the portafilter for easy cleanup.
Blossom One uses standard E61 baskets or a paper filter adapter nestled inside a La Marzocco group head to hold the coffee. With its ability to use paper, I would assume it’s possible to brew coffee that’s cleaner than the Clover or Trifecta—a common critique of both brewers. However, the entire system seems a bit complex for the benefits it offers.
The One proposes a systemized way of brewing that utilizes QR codes for consistent, programmed recipes and temperature stability to name a few. Although, by maintaining manual agitation and plunging there still seems to be ample room for inconsistency in brewing, in which case I wonder how this is better than a $20 AeroPress.
While I’m always fascinated by innovation for coffee bars and improvements in coffee quality and consistency, I also question the energy exerted in making the process of brewing coffee so complex. With an all-star development team that includes notable designer Joey Roth, along with a former NASA engineer and a product designer with experience at Tesla Motors & Apple, they’re more than capable of building something great. I just hope they’re receiving constructive feedback from the coffee industry to make it practical as well. I’d love to hear from anyone who’s given this a try.
Less than three months after Able launched their successful Kickstarter campaign to fund a production run of its latest Kone coffee filter, their beautifully designed white boxes have begun appearing in mailboxes and Instagram feeds around the world.
The new Kone and soon to be released ceramic brewer raised $150,000 more than the initial $5000 requested for tooling and production costs. Now with over 1200 backers supporting Keith Gehrke, the founder of Able Brewing, it’s become clear that his company’s new life after Coava, will create a bright new path on its own.
The Kone is a reusable, stainless steel coffee filter originally designed to fit the Chemex coffee maker, but can really be used with any vessel that supports its size and shape. The filter uses hundreds of thousands of micro-sized holes, created using a process of photo-etched steel, to form a precise filter pattern for uniform extraction.
I prefer not to compare the Kone with Chemex paper filters, because there is little comparison in the resulting coffee. The Kone is a unique brew method that incorporates pour over techniques to produce a heavier, oil-rich brew that’s still cleaner than a French press, which many people enjoy more than paper.
I’ve used the Kone since the first version was released more than 2 years ago. It’s been great following the progression of the filter and the company as it’s been refined over the years. The third and newest version is no exception.
The most obvious changes in the new design is the black plastic ring around the edge along with a new blunted tip. My reaction to the black ring was negative at first for altering the elegant, streamlined aesthetic of previous versions (it also slightly affects how well it sits in a Chemex).
However, once I handled the new Kone, the extra rigidity added to the shape and structure by the plastic ring becomes obvious and appreciated. For the coffee shops who use the Kone all day long, the new lip will greatly improve emptying spent grounds and seemingly extend the filters overall life.
The new blunted tip not only makes the Kone safer to handle, but it eliminates the small gap found on the tip of older versions, which was a clear path for fine grounds that increase sediment in the cup. This new “cap” plays a part in catching fines and helping produce a cleaner cup overall than the previous Kones.
With even smaller holes and a new pattern that becomes more concentrated near the tip, the new Kone offers more uniform passthrough as well. More of the water makes its way to the bottom, instead of leaking dramatically through the sides of the filter.
When the first Kone came out, I thought it looked incredible and worked great. It was new and there was nothing to compare it with. Once version 2 came out, the first one suddenly looked and felt like a prototype and the quality of the brew greatly improved.
The latest version, while losing some of its elegance, looks like a retail-ready product that could be sold on the shelves of Williams-Sonoma. From the packaging to the product itself, there’s a much greater feeling of value.
Below I’ve run an experiment to illustrate the progression of the Kone and how much the sediment has been reduced with each new version.
I brewed coffee with each version of the Kone using the same parameters and technique: 40 grams of coffee to 600 grams of water, 30 second bloom followed by a slow and steady center pour, using a medium grind (5-O on a Baratza Vario-W).
After each coffee was done brewing, I poured the result through a rinsed, white V60 filter to capture the sediment. Results pictured below begin with version 1.
From my highly unscientific experiment, you can clearly see how much the sediment is reduced with each new version, but there is always some sediment. With a refined technique, it’s likely possible to minimize the sediment even more, but I don’t find the current amount distracting and have been surprised by the clarity achieved.
Overall, the new Kone is a great improvement over its predecessor. From its reinforced new structure to the increased clarity in the cup—if you were a fan of previous versions then you’ll love the latest. If you’re just now discovering the Kone or have been waiting to purchase one, this is definitely the best version so far and you’ll be happy you waited.
Since the early days of brew method videos, there’s been an impressive evolution in the quality of the videos being produced. From the academic, to the clever to the action packed—tutorial videos have become a way for coffee companies to educate consumers, market themselves and have a bit of fun in the process.
The latest addition to the brewtorial archive comes from Cartel Coffee Lab in Arizona. Using the same “Stranger Than Fiction” notations as their earlier video, their latest—also produced by Ah Dios—gives the mid-century modern Chemex a southwestern flair.
Matt Perger, the 2012 World Brewer’s Champion, has put together a lovely V60 tutorial for ST. ALi in Australia. The two and a half minute tutorial is a fully annotated, “real time” brewing demo filmed to the sounds of Frank Ocean.
While there are a couple moves I’d consider a bit risky for those just learning, it’s worth trying out if you’re not satisfied with your own pourover method. Tap dat.
Stunts, explosions, & coffee. This may be the greatest coffee brewing video ever. From the same people who brought you syphon brewing in the dark, comes this explosive 80′s throwback to my favorite brew method—the AeroPress. Huge thumbs up.
Here’s a beautifully simple video of a syphon pot in action—capturing all its romantic serenity—only to be shattered with an odd and unexpected ending. Bonus points for being unique? I hear the clubs in Berlin are fantastic. Enjoy.
Smithsonian Magazine recently published a great article about the history of the espresso machine that’s definitely worth reading. While it doesn’t cover every minute detail, it mentions the key points that led to the creation of a commercial espresso industry and highlights the most important elements of quality espresso.
There is an art to the espresso as well. The talent of the barista is as important as the quality of the beans and the efficiency of the machine. Indeed, it is said that a good espresso depends on the four M’s: Macchina, the espresso machine; Macinazione, the proper grinding of a beans –a uniform grind between fine and powdery– which is ideally done moments brewing the drink; Miscela, the coffee blend and the roast, and Mano is the skilled hand of the barista, because even with the finest beans and the most advanced equipment, the shot depends on the touch and style of the barista. When combined properly, these four Ms yield a drink that is at once bold and elegant, with a light, sweet foam crema floating over the coffee. A complex drink with a complex history. -Jimmy Stamp
