The Kone Brewing System is a custom fabricated coffee pot, built specifically for the Kone coffee filter.
The Kone filter is a reusable stainless steel filter originally designed for the Chemex pour over pot. The newest and best incarnation of the Kone filter (I think this is the third version Able has made), as well as its accompanying custom fabricated brewing system, were Kickstarted thirty times over last June.
I backed at the $125 level, which got me the whole brewing system with filter as a reward. And it all arrived about two weeks ago. I’ve since brewed 4 pots of coffee with my Kone Brewing System and they’ve all been quite delicious.
The Brewing System
The first thing I noticed after opening the box is how big the Kone Brewing System is. I was expecting the Brewing System would hold around 500ml of coffee, but it actually can hold twice that amount.
The Brewing System is made up of four components: the pot, the filter, the filter casing, and the lid.
When brewing, the filter rests inside the casing which rests on top of the pot. When done, you remove the top casing (using the rubber heat shield grip), and place the lid on top of the pot.
It’s an extremely handsome rig, and I’m very impressed with the design. It looks great on the breakfast or dinner table, and it looks great sitting on the shelf in our kitchen.
There is no doubt that the guys at Able put a lot of thought and attention into the entire Kone Brewing System. Everything — from the packaging to the included card of instructions to the filter and ceramic pot themselves — exudes attention to detail, care, and thoughtfulness.
Alas, the Kone Brewing System can only be used with the Kone filter. The ceramic top-piece which holds the filter is, as I mentioned, custom fabricated specifically for the Kone filter. There is no internal “V” shape which could accommodate a paper filter if you wanted — you must use the Kone metal filter.
The Kone Filter
They say the advantages of using a metal filter rather than paper are: (1) reusable; (2) you never have to pay for paper filters again; and (3) metal filters allow more oils from the coffee bean to pass through when brewing, thus making a fuller cup of coffee
You can’t argue with 1 and 2. And if you are making a big pot of pour over every single day, in the long run a metal filter will pay for itself.
As for the taste. Well, I personally haven’t been able to tell any significant difference between a cup of coffee brewed with a paper filter and one brewed with a metal filter. In fact, if I had to chose, I’d pick paper filters.
The AeroPress is certainly my favorite brewing contraption, and I use paper filters with it. I even have a metal disk filter that fits my AeroPress and I haven’t noticed any difference when using it rather than the paper filters.
One of the disadvantages to using a metal filter is that some of the “coffee dust” gets through the filter and into the bottom of your cup of coffee. Such as the grit you get when brewing with a normal french press.
When it comes to the day-to-day practicality of using the Kone Brewing System, it is not going to be my new daily driver.
For one: compared to the AeroPress or v60, cleanup of the Kone is more involved and tedious because I have to rinse and scrub the filter to get the coffee grinds out of it. Secondly, the Kone Brewing System is intended for making several servings of coffee — it’s a lot of coffee gear to use and clean for the 10-ounce cup I usually brew each morning.
I see the Kone Brewing System as being akin to my Siphon vacuum pot. The Siphon is quite impractical for day-to-day use, but it’s great for when company is over because it’s so fun to use. The Kone is in a similar category (making table-side pourover is always fun), and it can make almost 3 times as much coffee as my siphon.
If however, I was regularly brewing a larger pot of coffee instead of just my single cup, then a big pour over pot like this is just what I would use each day.
If you already own the Kone filter, the Brewing System is $120 by itself. Otherwise it’s $160 with the filter.
Being one of the Kickstarter backers I was privy to much of the behind-the-scenes of what goes in to the molding, firing, and packaging of the Kone Brewing System. And without significant economies of scale, $160 is probably as affordable as Able could get it. Which is unfortunate because as much as I like the Kone Brewing System, $160 is a hard price to swallow.
As cool and attractive as it is, it’s incredibly hard to justify the extra cost of the Kone Brewing System over a Chemex. The Chemex is just as capable of a coffee maker, but it’s one-third the price, holds 10-percent more liquid, works great with the Kone filter, and also works with paper filters.
Since I’m caffeinated, I’ll get right to it: The Espro Press makes an amazing cup of french press coffee.
These things are finally starting to show up for sale, so it’s time to review the one I got from Kickstarter back in April.
The original Espro Press is an 8-ounce single-serving press pot. I’d never even heard of it before I saw their project on Kickstarter, where their aim was to build a 32-ounce version. Since I am genetically predisposed to back any coffee-related project on Kickstarter, I pitched in my $85 and “pre-ordered” one of the large Espro Presses.
Their project was funded (more than five times over), and in early April of this year I received my 32-ounce (1,000 ml) press.
Seven days a week I brew a cup of coffee. Most days it’s with my AeroPress, but once or twice a week I like to make french press. People often ask me what makes a better cup of coffee — AeroPress or french press? Well, they both make fantastic coffee with their advantages and disadvantages. I enjoy both for different reasons; they’re both favorites, really.
So what is it about the Espro Press that makes it so much nicer than my Bodum french press? Two things:
1. Double-walled Steel Vessel
The pot is durable and rugged. And it’s heavy. Since it’s stainless steel, the best way to keep it clean is to hand wash it. But I’ve been putting it in the dishwasher since I got it and there are no rust spots.
The double-walled steel construction helps keep the coffee hotter for longer. Normally after brewing a pot of french press I would pour it into a vacuum thermos. Now I just bring the press downstairs to my office with me. Though the Espro Press doesn’t keep the coffee piping for 3-4 hours like my vacuum thermos does, it does keep it hot enough for over an hour (about how long it takes me to finish a pot) and it means one less vessel to clean.
|Time (min.)||Temp (F)|
Since the press rod and lid are metal, they conduct a good amount of heat. Which means some heat is lost through the rod and lid, as well as the fact that the lid gets very hot to the touch. But it also means they are built to last — a tradeoff I’m willing to accept.
Double-walled stainless steel french presses are not a new thing. For example: the $100 Frieling french press has a high-quality double-walled stainless steel carafe, not unlike the Espro Press. But the Frieling has the same basic steel mesh filter that you’ll find in a common Bodum french press.
What makes the Espro Press the Espro Press is the filter.
2. Double-Layered Micro Filter Basket With Rubber Seal
It’s a double-layered micro filter basket with a rubber lip seal. It’s unlike any other press pot filter I’ve seen, and it makes a great cup of coffee.
The filter basket is designed to keep as much of the grit out of the brewed coffee as possible. Here’s a comparison of the grit left at the bottom of a cup of coffee by an AeroPress, an Espro Press, and a classic french press:
Obviously the AeroPress wins the “keep as much grit out as possible” competition because I used a paper filter.2 The Espro Press, however, has far less grit than the classic french press. And since the Espro uses a micro filter, you don’t lose any oils to a paper filter. (Though I don’t know that I’d even be able to tell the difference.)
I drank all three of the now empty cups of coffee you see above. Comparing the Espro Press to the French Press side by side like that I realized just how superior the Espro Press is. The classic french press coffee was noticeably more acidic and bitter (not horribly so) than the Espro Press coffee.
I’ve always loved the rich and bold coffee that a french press makes, and the Espro seems to make the best version of it.
The Espro Press, despite having a much more complex filter than your average french press, is still just as easy to clean.
Removing the filter basket from the pot, I simply rinse off the grounds from the sides of the basket, rinse out the pot itself, and then put the whole thing into the dishwasher.
The basket can be easily separated so as to clean out the middle zone of the double walls. Until today, I had yet to do this. Here’s a is a shot of the grit that accumulated inside the middle filter wall after 30 or so uses of the Espro Press (and, for the record, I intentionally didn’t clean the inside wall of the basket, because I wanted to see how dirty it would get over an extended period of time):
There’s no reason to let even that much grit accumulate. Taking apart the filter basket is quite simple (it easily twists apart), allowing you to easily separate the outer and inner baskets every time you put it in the dishwasher.
The Best Recipe
The Espro Press carafe can hold 1,500 ml of water. But that leaves no room for any coffee grounds or the filter basket. You can brew up to 1,000 ml of coffee, but I’ve found that the best recipe is when you brew 750 ml.3
The reason I shy away from brewing the full 1,000 ml capacity is that large filter basket gets in the way when you are brewing that much liquid. About 230 ml of liquid are displaced into the basket and thus don’t fully brew with the rest of the water.
Therefore, when brewing 1,000 ml of coffee I do 70 grams of grinds instead of the recommended 60. This causes the water below the basket to brew stronger, and then be diluted a bit once the basket is pressed down and the previously displaced water rejoins the brewed coffee.
The recipe I prefer is the one that Espro recommends for a 3/4 pot:
- 45 grams of coarsely ground coffee
- 750 ml of hot water
- Pour most, stir, pour the rest, wait 4 minutes, press
Now, if you’re looking for an iPhone coffee app, I can recommend one of those as well.
- For comparison: I brewed a Bodum glass french press alongside the Espro Press. At the 4 minute mark, just after pressing the grounds, the Bodum coffee temperature was 158° — a temperature it took the Espro nearly 30 minutes to reach. ↵
- This is one reason I love the inverted AeroPress method with a coarse grind. It’s not unlike brewing a pot of french press, but thanks to the paper filter you keep all of the grit out of the brewed cup. ↵
- For reference: the classic Bodum french press has a maximum brewing capacity of 750 ml. ↵
I’m on location at The Roasterie coffee shop in Leawood, Kansas, where I was just handed a hot americano with steamed breve.
My initial impression is that it’s delicious.
Americanos at The Roasterie are available hot or iced, and in four different sizes: 8, 12, 16, and 20 ounces. I chose the 12-ounce which, including the extra cost for the breve, cost around $3.
The drink comes in a white paper cup with an additional paper sleeve around the cup. The sleeve not only helps to keep the drink warm, but it also protects your hands from the heat of the cup. There is also a black plastic lid which secures to the top of the cup. The lid serves a dual purpose: it not only helps keep drink hotter for longer, it also acts as a low-level form of spill protection should you accidentally knock your coffee cup over.
After consuming nearly all the contents in this cup, I’ve found that drinking coffee is not only enjoyable and relaxing, it also stimulates the little grey cells when any sort of thinking and creative work is being done.
Search the iTunes app store for “coffee” and you get over 700 search results. On my iPhone I have 7 coffee apps installed: 4 of them have similar functionality, 3 of them are unique from the others, and only 1 gets used on a regular basis.
Affogato is designed by Visioa, an iOS development studio based in England. The app is, more or less, an encyclopedia of coffee terms, types, and brews with the relevant descriptions and overviews. There are not many specific details directly related to how to brew a specific type of coffee. Rather, Affogato is primarily an informational app. Though some of the explanations of different drinks include an overview of what that drink’s generic recipe is.
Decaf Sucks is a social network-type of app, where users can (a) post suggestions and reviews of local coffee shops; and (b) find local coffee shops based on other peoples’ reviews.
The idea is great. In reality, however, I have not found any real-life benefit from the app. In part because I am already aware of all the local coffee shops that Decaf Sucks recommends to me here in Kansas City. Also, when I have gone out of town the app has not had enough reviews for where I’m at to be able to recommend a local coffee shop to me. I’ve found that a question to my Twitter followers will yield more suggestions about where to go.
CaféTimer is nothing more than a 4-minute timer with a picture of a French Press. I love the simplicity of it: launch it and the timer starts. But I would love to see a few options to add different timers. I, for one, do not brew a pot of French Press coffee every day. Usually I brew my AeroPress, and sometimes I brew my siphon pot. Neither of these brew for 4 minutes.
And so, if I just want a quick coffee timer, my stove’s timer is usually the quickest. Though I do also use Siri.
The Other Four Coffee Apps
There next 4 coffee apps are very similar to one another, and their primary function is providing brew recipes, timers, and detailed information on how to brew various types of coffee.
When I think of a coffee app, these are the types of apps I think of.
These are coffee apps that tell me the proper ratio of coffee grounds to water for the various types of brewing methods. Ratios are important because with them you can brew 8 ounces of coffee just as successfully as 32 ounces. And if you’re brewing with a new type of method, detailed recipe-based apps like this give you a good starting point.
This app is done in conjunction with the well-known Intelligentsia coffee roasters and brewers. The app features a list of types of coffee beans, detailed instructions for brewing various types of coffee, and a timer.
The list of coffee beans is basically a catalog of their coffee offerings. With information on the bean, the roast, its origin, and more. I’ve never used this part of the app.
The timer is just that. It has pre-determined times based on the type of brew method you are using. You can select your brew method and then start your timer. The brewing methods section is great if you are learning a new way to brew some coffee. The provide detailed and illustrated instructions for Cafe Solo, Pourover, Chemex, Cupping, Siphon, and french press.
If you’re just learning about these various brewing methods and need beginner-level instructions for how to prepare the coffee and the tools, then the Intelligentsia app is a great resource. However, after that initial instruction the app becomes less helpful in providing information for branching out how you brew your coffee.
The app “Coffee Timer!” is a reference app for setting the appropriate ratios of coffee grinds to water and for timing your brew. It comes default with settings for french press, siphon, chemex, popover, AeroPress, and the clever dripper.
Though I like the clever drawings on the front of the app’s home screen I find the actual coffee-brewing page of the app difficult to adjust, especially on the fly as a task that you may be adjusting a little bit every day. But I do like that you can save your own recipes for various types of brewing methods, such as your single-serving french press and your family-sized french press or your extra-strong AeroPress and your regular-strength AeroPress.
Similar to the app “Coffee”, Bloom also offers a list of coffee-to-water ratios and timers for various brew methods. It has the same six methods as “Coffee” does, but with Beehouse instead of AeroPress.
You can add your own recipes to the list, duplicate current ones unto creating your own, and even share those recipies via email, Twitter, or MMS. I created a recipe for AeroPess and Bloom was smart enough to assign an AeroPress-looking icon next to my new recipe. I made up a randomly-named recipe called “Shawn’s Fave” and Bloom gave it a more generic coffee bean icon. I made a recipe for “Drip” and Bloom gave it the same generic bean icon.
I like the simplicity of Bloom’s interface for a specific coffee brewing recipe in that it displays the coffee and water weights, the bloom and brew times, and has a timer ready to go all on the same screen.
However, what I do not like is that all information for custom recipes has to be entered in manually. There is no way to assign a ratio. Rather, you must manually adjust the coffee-to-water recipe. And therefore: (a) you need a different app to figure out the proper ratio: and (b) you can’t adjust your coffee recipe on the fly.
My favorite of the whole lot of coffee apps is Brew Control. As someone who is already familiar with all my coffee tools, I have found Brew Control to be the most easy to use for my daily coffee brewing.
It is extremely simple to set the proper measurements for a brew method. It supports both weight (in grams) and volume (in ounces) for the coffee and the water. My mind thinks in ounces of water, but my scale thinks in weight.
I use Brew Control by first deciding how much coffee I want to brew and setting the water dial in ounces. Then I translate that to grams, and I have my coffee and water ratios. Adjusting the ratio is easy as well.
I don’t know about you, but I brew my coffee a little bit different every day it seems like. And so I highly value the ability to tweak my recipe on the fly.
Brew Control has pre-defined recipes/ratios and timers for AeroPress, Auto drip, Chemex, espresso maker, pour over, french press, and siphon. You cannot add new brew methods to the list, but you can customize each current one as you see fit.
My only nit with Brew Control is the UI design. It could use a bit of polish, but only around the edges because the way the app’s design and functionality are built in is actually quite clever. Or, in other words, I love the dials.
Of all the coffee apps I have, Brew Control is the only one I use regularly. And for coffee nerds with iPhones, this is the only one I’d recommend spending a few bucks on.
As I write this sentence there is a hot cup of coffee sitting next to me, brewed using an AeroPress.
I own a drip coffee maker, a Turkish coffee maker, two french presses, a stove-top espresso maker, a siphon, and now an AeroPress. The stove-top makers never get used; the drip maker is only for when lots of company comes over; the siphon gets used about once a week at most; and the french press gets used every single day. Until today.
Savvy readers of the site will know that pretty much every day of the week I brew half a pot of french press coffee. The siphon also makes great coffee and is a lot of fun to use. But it takes lot of work and is very impractical for daily coffee making.
This is where the AeroPress comes in. It makes a cup of coffee on par with the french press and the siphon and is the easiest of them all to clean up.
You can’t ask if the AeroPress makes a better or worse cup of coffee than a french press or siphon — AeroPress brews coffee differently and brings out different flavors and tones. It is not better or worse, it is different, and yes, it is good. If you like french press and/or siphon then I bet you will also like AeroPress.
There are many ways to brew a cup of coffee with AeroPress. The common way is to brew it more similarly to how an espresso machine would: by pushing a little amount of water through a lot of fine grounds in a short amount of time. Once you’ve brewed and pressed your AeroPress your cup only has about 3 – 4 ounces of coffee in it. Very strong coffee. Then you can add hot water or hot milk.
There are some huge advantages to this type of brewing that you will never get with a french press:
You brew the AeroPress with 175-degree water. Using a bit cooler of water means you are far less likely to burn your grounds and so more likely to end up with a cup of coffee that is not very bitter or acidic.
You brew a lot of grounds with very little water and you do it quickly. This means you don’t over extract the coffee and your chances of ending up with that smokey-burnt flavor is also far less.
After brewing you can then add piping hot water to your 4 ounces of AeroPressed coffee and bring the temperature back up to piping. I, for one, like my coffee to be as hot as possible.
All of the above advantages to the AeroPress can be overcome by someone who is good at making french press. There is no reason you can’t brew a great cup of french press (I do it every day), but the margin for error is smaller with the AeroPress. However, there is one advantage that the AeroPress has which the french press or siphon will never have: clean up.
The AeroPress basically cleans itself as you use it. Once you’re done pressing your coffee, you simply untwist the plastic filter cap, pop the coffee puck into the trash, rinse off the bottom of the rubber plunger, and you’re done. Clean up takes about 10 seconds. By far, my biggest annoyance of making french press coffee every day is the cleanup.
If you’re persnickety about your coffee and brew some every day then the AeroPress may be your cup of tea.
My uncle Louie, who is recently retired from 40 years as a tech consultant, has acquired a taste for coffee. Just this week he bought a french press, and so he sent me an email asking for advice knowing that I use one every day.
Traditionally, the french press is the finest way to brew a cup of coffee. And despite popular opinion, it can actually be quicker than making coffee with a drip coffee maker. However, the french press is more involved for the person brewing the coffee, as each step is done by hand, but that is something I personally enjoy about it.
Great coffee starts with great ingredients: water and coffee beans. You should use only the best water — filtered, bottled, or (if you’re my dad) reverse osmosisified — whenever possible.
I buy my beans whole and grind them just before brewing them. When coffee beans are ground is when they give out their flavor. To use pre-ground coffee beans is to use them at their worst. To grind them just before you brew them is to use them at their best. Moreover, if you use pre-ground coffee chances are you aren’t using the coarseness for a french press. Pre-ground coffee is almost always too fine for proper brewing in a french press.
To grind your own coffee, I recommend a conical burr grinder. I use this Breville.
What many people do not know is that there is a big difference between a plain burr grinder and a conical burr grinder. In fact, most inexpensive burr grinders do a worse job grinding your coffee than a cheap blade grinder would.
One of the reasons people buy a burr grinder is because it will produce a more consistent grind (the biggest complaint against blade grinders). However, the average burr grinder has flat burrs. And though you will get consistent grind it often comes at the expense of the ground bean.
With conical burr grinders the burrs are shaped like a cone. This means there is a larger grinding area for the same diameter, allowing the conical burrs to spin at a slower speed. And you want your coffee to be ground slowly. Grinding at high speeds (as most regular, flat burr grinders do) heats up the burrs and results in burnt coffee beans and damaged grounds.
For brewing in a press you want an even and coarse grind. I set my Breville to the most coarse setting it has. (Around the holidays I like to add a teaspoon of cinnamon to the grounds before I pour the water in. It gives the coffee a nice spice that goes well with snow and Christmas music.)
I use an electric kettle to boil the water. Once the water has reached a boil I let it cool for just a moment to let it stop bubbling, so the water is right around 200°. Then I pour the hot water into a measuring cup to get the right amount of ounces for how much grounds I’m brewing, and then I pour it into the french press over top of the coffee grounds.
Something which is of upmost importance is the ratio of coffee beans to water. Different people have different opinions about this, but I use 2 tablespoons of beans (measured before they’re ground) for every 6 ounces of water. If that ratio results in coffee which is too strong for you then add the hot water to your cup after you’ve already brewed the coffee. If you water down your beans while brewing, then you’ll over extract and end up with bitter coffee.
After I pour the water over the coffee grounds in the french press I let it sit for a few seconds and allow the coffee to bloom. I then give it all a really good stir, place the lid on, and set a timer for 4 minutes.
When it’s time to press the coffee I slowly push down on the filter, and then pour it into a thermos. I like my coffee piping hot and so I drink just a little bit at a time — black — to keep it as hot as possible. This also plays well into my affection for small mugs.
Here is the gear I use, or wish I used, to make my coffee. Equip yourself via these Amazon links and you’ll help pay for my next cup of coffee.
When at coffee shops I almost always order a 12-ounce, double Americano with a little bit of half-and-half steamed in.
I used to just add cream to my Americano at the coffee fix-up bar, but now I ask the barista to steam a little bit of half and half in to the drink instead. (This is not the same as an Americano Misto. An Americano Misto is half water and half milk.)
There are several advantage to getting the half-and-half steamed in:
- it keeps your Americano piping hot (by not pouring in cold creamer).
- it adds flavor.
If you prefer lattes or cappuccinos, an Americano is about half the cost, but with the steamed-in creamer it tastes nearly the same.
On occasion the cashier wants to charge me $0.50 extra — calling it a “breve”. Sometimes I think that’s a crock, and I tell them they already offer free half-and-half at the coffee fix-up bar but that you would prefer the barista to steam it in for you so your drink stays nice and hot. And sometimes I realize I’m at a local coffee establishment and every little bit helps them keep the lights on and the coffee hot.
It’s a great drink, and you should try it sometime.
