Oh, no! Not another coffee is wine article!! Ever since the coffee trade learned how much wine is marked up before you and I buy it, they’ve salivated over this analogy. Is coffee like wine? Of course it is, just like maple syrup, blueberries and salmon. There are grades and flavor differences based upon where it was raised, how it was processed and just flukes of nature that are recognized during evaluation and priced accordingly.
Let’s go through this article, which appears in the Wine Enthusiast, and see how they did. Here’s the link: http://www.winemag.com/February-2014/The-Wine-Lovers-Guide-to-Coffee/?goback=%2Egde_150968_member_5826407454983876609#%21
“Joe-ography.” Cute. Okay, let’s talk about geography. The writer makes the argument that coffee is like wine and geography affects the beans’ flavor as it does grapes. I basically agree that geography appears to affect coffee. But, of course there’s much more to the story and differences abound. Most of the world’s coffees are from two types of bean (He acknowledges this in paragraph 2). Wine is from lots of different grapes and of course geography affects a chardonnay grape, so that one grown in France tastes different then one grown in California. He says wine can be divided into old world and new world. I can’t see how that applies to coffee in any way. While geography is important to coffee and wine, the paragraph does nothing to convince me that coffee is like wine.
Things You Didn’t Know About Coffee. All of these are ostensibly correct. A few of them would make me see similarities to wine, back to terroir (where it was grown and climate conditions). The rest, things like dark roast (which he recommends at least twice) are not analogous to wine. Can you imagine a why don’t you drink wine article in a coffee magazine pointing out the virtues of heavy oak? That’s more like roast, as it’s among the things the trade does to goose up flavor after the harvest so to speak. I’m sure the coffee folks he relied upon told him to point out that certain coffees feature more acidity, but I think it’s better to say that different coffees feature different acidity acidity and character due to their geography (again) and leave it at that. Obviously he has mixed acidity and acid as the same. They are not the same and titling the point “acid trip” adds confusion.
America’s Seven Best Roasters. If a coffee magazine featured a wine extolling article and claimed there were top seven winemakers, I propose by next morning there’d be one few coffee writer, no doubt buried in an undisclosed winery as a message to trade writers like us never, never to do this again. I happen to have had coffee from every one of these shops and they are all in the top rank but there are dozens of equally good roasters, and while I like to extol the roaster’s role in coffee, to be brutally honest, there is a lot more variance in the quality of even the best roaster. Dare I suggest that the roastmaster’s job is to roast just enough to maximize acidity, but at the expense of so-called development, or balance. I’d argue that wine is inherently more created. Since wine is truly a prepackaged beverage, the choices of variety are expanded, blends are the rule, not the exception. Brewing is done for you, perhaps years before. Coffee brewing, the point of consumption culinary art that you and I, or our neighborhood barista has mastered to extract exactly the right flavor balance from even the best grown, best roasted coffee is never mentioned.
The Wine/Coffee Connection. This is an, if you like this wine, you’ll like this coffee section. Actually here I think the writer succeeds. In most of the examples I think he got it close to how I see it. And, I think it’s analogous. There is a spice in most Sumatras. A Pinot Noir has more lightness like a Central American, although here again, there may be more differences variance between coffees. I’ve had some incredibly big Central Americans as I’ve tried more small plot samples.
I’m sure the coffee business says, “Great they spelled our name right.” I’m not against the idea of promoting coffee to another culinary consumer group with deep pockets and finicky taste buds. But, overall, they missed the boat. Coffee is like wine in its complexity. Beyond that, its geography factor is different, its delivery state to the consumer is different. The roaster’s role is more limited than the vintner’s. The consumer’s role is much greater than the cork-popping wine aficionado’s. Oh, and wine has a giant shelf life where coffee has virtually none. Nonetheless, I applaud the attempt.
Is brewing a science or an art?
A colleague recently posted this article on Linked-In. http://www.ajcoffeeco.com/blog/coffee-brewing-science-or-art/?goback=%2Egde_43141_member_5796946764351184896#%21
It’s a fairly concise piece that attempts to answer its question, but along the way I find it gets confused. It makes the point that a true professional barista should not need to use a scale and that an accomplished coffee barman should be able to make a decent espresso with no extra equipment. The author then encourages the barista to use more eye contact while making the drink for their customer.
All this may be appropriate advice, but I’m afraid I find it ultimately unhelpful. Rather than disassemble their perhaps well-intentioned article, I’m going to simply put forth my own views on this subject.
Does taking your coffeemaker's temperature seem like overkill to you? I think it's worth it.
The headline’s question is a good one. My answer is brewing is a science to make a cup of coffee – which I consider a work of art. Brewing is chemistry. We are attempting to use water as a solvent, which the heat enhances, which is why we heat the water. From then on it’s time and terms. The longer we have contact between the water and the grounds the more coffee flavor matter we extract. Now, there is an element of art involved – that is the subjective decision of how much is enough. Truthfully, there is no right answer. The fact that different parts of the world have different brewing standards shows us this. But, a good barista, or any of us when we brew, should be aiming to brew it to the tastes of the person who will be drinking it, and the methodology we use should be thought out and repeatable. Hence, it is both art and science.
Items like scales, thermometers, measuring spoons are designed to make the process measurable and repeatable. I recall the bad old days of the 1990s when in the Specialty Coffee Gold Rush, I met many entrepreneurs who were convinced their product was 100% art, and they claimed no matter how you brewed their coffee, it tasted great, far better than so-called commodity coffee. In fact, I felt some of these folks viewed people like me who promoted the importance of brewing as simply geek-types who could take the fun out of anything with our measuring obsession.
I think it’s gotten to the point in history where most people in the coffee industry and many consumers accept the fundamental truth that the brewing process is vital and of equal importance with a well-bred, cared for, properly roasted bean in order to make a good-tasting cup of coffee. The word “decent” is a word I reserve for commodity in both product and experience. I am sure I could guess my way through the brewing process and get a decent cup, just as when cooking I could guess at my stove temperature, time and spices and get “decent” food. But, why would I?
As far as eye contact, I often choose a simpler method to brew coffee when entertaining. Most cafes offer two tiers of brewed coffee: there is bottle-brewed coffee made (hopefully) hourly and stored, then dispensed quickly and at a competitive cost. The extra time and cost applied at the brew bar is to achieve an ultimate, fresh and flavorful cup. The freshness alone should justify the extra effort to someone who’s going to sit and savor that cup. Using tools such as a scale to make it as exact as possible is simply common sense. There’s no hocus pocus about it.
I do not always use a scale under my Chemex, but this is because I’ve brewed with one for twenty years. I know where 750 weighed grams of brew lies on my brewer, but this does not mean I do not measure.
Weighing coffee brew for consistent brewing strength. Do you?
There surely are connoisseur practices that, while possibly enhancements, I separate them from good brewing practices. For instance, the ritual of pouring hot water to wet the filter before brewing is, in my experience, optional. Carefully measuring both water and grounds, whether weighing or using a measuring spoon, is not an option. Grinding using the best appliance affordable just before brewing, is a given, not an option. My wife always rinses her cup with boiling water before I pour her cup. I consider that an option. Timing the contact between water and grounds is critical and determines the grind I use and is not an option. I never guess at measurements. As much of a storyteller as I am, when I’m entertaining, I always beg the guests’ indulgence with my breaking eye contact with them as I prepare our coffee. The few times I have broken that rule we have paid for it.
While coffee brewing is a science, this does by no means mean that all the science is known, and searching for right practices can be considered an art. For instance, after pouring hot water into a press pot, how much do you stir? Stirring, as those of us who brew regularly with this method know, facilitates extraction. One reason the vacuum brewing method is so highly regarded is its inherent water agitation causes it to extract so efficiently. Both the stirring of a press and the bubbling vacuum are hard to measure. Obviously there is a formula at work, but who knows it? I don’t and I have yet to meet anyone who does.
So my complete answer is coffee brewing remains both an art and a science. As Chesterton said, “Art, like morality consists of drawing a line somewhere.” Some years ago an inventor introduced a product that fit over our ears that would enhance our ability to hear music. Although every review confirmed the product worked, it did not sell well. Apparently there are limits to which connoisseurs will go for even the most rewarding hobby. My advice is to continue to measure and treat coffee brewing as a science, with the caveat that much is still unknown, including just how you and your friends like to drink it. My guess is you’ll enjoy your coffee and not ruin your life by making your rituals too obsessive.
Congresswoman Jan Schakowsky D-IL, Event Sponsor and I grab a cup and chat about, what else? CoffeeCon 2014!
During the recent National Coffee Association Summit in Philadelphia, I discovered the NCA planned a one-day coffee event for Congress to help bring attention to coffee and coffee issues. The NCA’s Donna Pacheco seemed to have everything planned, but when I volunteered she graciously suggested I might be able to discuss coffee with the Congressional staff who attend.
The issues in coffee are pretty straightforward. I think most everyone shares them. NCA CEO Robert F. Nelson would probably say the coffee industry wants to be more or less self-regulating, like the cosmetics industry. Doesn’t it make sense that the folks who know the most about how to proceed are those closest to the situation? How much labeling do we really need on one of the world’s oldest products? Think of the apple (fruit, not iPod). Do you really need or want nutrition information stamped on your apple? Is it worth the cost? And coffee, with things like caffeine content varying widely depending upon variety and roast, would impose an entirely new cost on the roasters, which of course hurts the smallest guys most. Does a centuries proven safe beverage like coffee really required to be treated like a laboratory-fabricated energy drink?
Also, how about some immigration reform ala coffee? Isn’t coffee that’s brokered, stored, roasted and brewed in the US entitled to be called Made in USA? These are issues the industry wanted to get across. I decided my role was best served by listening and observing first. Second, if asked I would talk brewing and consumers.
500 Congressional Coffee drinkers. There is hope, America!
I did wish to stump for more relationship building from seed to cup. I can’t think of a more potentially useful group to help with this than the State Department, who is charged to look for ways to improve communications with our neighbors, many of them coffee producing nations. CoffeeCon’s mission is to build a kind of “farmstand rapport” between U.S. consumers and their favorite coffees’ farmers. I know it’s possible. In CoffeeCon v.1 I recall posting on Facebook, offering a free booth to any farmer able to make the journey to Chicago. Honduran farmer Gerardo Casco came and exhibited and spoke to our attendees. It adds a global dimension to CoffeeCon and closes the loop from creator to consumer many in the industry speak about.
Coffee On the Hill (I know I keep calling it Coffee For Congress) was well attended. More than 500 shared coffee with us. The top-end coffee Barista Guild Chair Trevor Corlett and his fellow Madcap colleague Ryan Knapp ran out of the Cup of Excellence coffee they brought – I take some blame for this because I kept touting the coffee and downing several servings myself. Beans wise, I can’t help my own affection for John Martinez’ Honaunau Estates Kona Coffee beautifully represented the best of U.S. grown coffee.
I brought the rarest and best USA coffee: J Martinez Kona Honaunau!
Steve Schulman of S&D Coffee brought enough of their coffees for a representative world flight that featured some genuinely rare breeds, brewed with Bunn-supplied brewers, all organized and brewed to precision by Bunn’s Debbie Russell. There were also cuppers who set up stations from Coffee America (USA), Corp., Massimo Zanetti Beverage USA, and Noble Americas Resources Corp. They are to be commended for bringing the high degree of professionalism. Frankly, I didn’t expect to see replicas of coffee evaluation that trade uses. It added a nice Mr. Science touch to the proceedings. Note to self: See if these guys will come to CoffeeCon 2014.
As you can see in photo 1, I met Congresswoman Jan Schakowsky, D-IL who sponsored the event. She’s asked if I can bring CoffeeCon to her district, and of course the answer is a solid… maybe – haha, I learn fast here! I also met Congressman Darrell Issa, R-CA who of course is politically opposite of my Illinois Congresswoman. Typical of elected officials I’ve met, both were charming and engaging. I met many congressional aides, who all wanted to know which brewer, how to use it, and what my favorite coffee was. I spoke eloquently on the first two and diplomatically, even evasively on the last. Which coffee is my favorite? Hmmmm. (I told you I wished to show myself a fast learner. haha.)
I believe the event was a success in all ways. So, to answer an obvious inside joke: Did we energize Congress? Hmm. Let’s just say they left energized. Certainly it was great fun.
PS: Special thanks to Joe De Rupo, National Coffee Association Communications and Media Director for making it so easy to attend their events, and for snapping my photo with Congresswoman Schakowsky.
After a couple of no hitters, Kitchen Aid knocks it out of the ballpark with this one! Makes great coffee, attractive and flexible.
It seems everyone wants a personal coffeemaker. A few years ago I recall going to the International Housewares Show and seeing a few machines trying to be K-Cups without infringing on their ironclad patent. Now, every manufacturer has a horse in the single-serve race. Most of them are the opposite of a manual pourover such as the Hario V60. Most are mediocre at best, as is the Keurig’s original K-Cup. They underextract because they try too hard to be fast or their puny heating elements can’t get the water hot enough to extract coffee’s precious oils efficiently.
The KitchenAid Personal Coffeemaker is their entry into this competition and I am delighted. It does almost everything right and nothing wrong. Let’s look at each feature and then its measured performance.
1-4 cups! Most single serve machines are just that… one cup. The KitchenAid offers a range. Although it’s listed as a three cup, I was able to fill the water to maximum and get four full (near) five-ounce cups. This is just about perfect for me and a friend, three friends if we each want one cup. It’s easy enough to brew again if we’re really thirsty.
The KitchenAid Pers0nal Coffeemaker brews into a supplied to-go travel cup with a tight fitting lid, which doubles as a carafe. This shows their awareness of the market, because likely lots of folks are making their cup to travel. The personal brew size can be between six and 18 ounces. I always brewed maximum and I think you should too. I’ll tell you why in a moment.
There is a permanent gold filter, one that’s dishwasher safe.
The water container is removable. I couldn’t care less about such things but you may and it does make it easier to fill at the water tap.
Now to the tests: I always made a full batch. It is because drip makers are optimized for a certain grind and grounds-to-water ratio. At maximum fill the brewing contact time between water and the coffee grounds will be six minutes. If you brew less, that time shortens, and so does the strength unless you play with the recipe or the grind. Possible, but I say learn to make it one way and stick to it.
Most coffeemakers do not get the water hot enough. The Kitchen Aid single serve gets the water to 195°F, or higher. It takes about a minute to reach altitude but once it does, it stays there. The full-size Technivorm KB741 is ruler flat 200° but the KitchenAid is close enough that most of us won’t care and it shows you the company this one keeps.
Another failing of many drip makers is the ability of the showerhead to thoroughly and evenly soak the grounds beneath it. This means a lot because dry grounds don’t give any flavor to your cup. You waste fuel as they say in Car and Driver. If you use the kind of coffee I used to test this brewer, such as Dark Matter’s Cup of Excellence Colombian, you will see how important it is to realize the value of your coffee through thorough extraction. The Kitchen Aid is among the best automatic drip machines yet tested in the ability to soak the grounds. It is as good as the full size Bonavita, which leads in this category. Both it and the Kitchen Aid beat some other highly rated and costlier makers.
The brewing contact time is critical because your cup’s flavor depends upon exact extraction. When people complain of bitterness in their coffee, it is most likely due to a too-long contact time. The Kitchen Aid accomplishes its mission within six minutes. This is perfect. Shorter risks underextraction and less taste and even potential sour notes. Longer risks bitterness as I wrote above.
I know some of you are saying, “Kev, I have a Keurig and I have an insert that takes regular coffee. How is this new KitchenAid better?” Fair question. Even assuming the K-Cup King met the other parameters of time, temperature and water contact, the Keurig and in fact all K-Cup machines use a non-standard grind, an extremely fine one. It’s the only way it can give a decent extraction within the comparatively short contact time and meager grounds-to-water ratio. It’s hard to match, assuming your home grinder can do it at all. The KitchenAid Personal Coffeemaker uses a standard automatic drip grind. To me, it’s a no-brainer. And my tests confirmed the quality that went into KitchenAid’s design.
In addition to the great tasting Cup of Excellence, I tasted Jim’s Organic Coffee Wonder Brew blend. This is a darker than normal roast for me, but Jim did a nice job turning out a roast that can be described as syrupy but no over-roasted notes or excess caramelization, common side effects of darker roasts. I tried some of Counter Culture’s Banko Gotiti Ethiopian Yirgacheffe. My friend Rich Futrell recommended it so highly and it was the end of bin so I grabbed it. This coffee is a floral bouquet and it will taste good in almost any decent machine but a great one will give you the fruit in balance with the body. Otherwise fruity coffees can easily taste unbalanced to me. The Kitchen Aid acquitted itself admirably, producing a cup right on part with the previous day’s Chemex of the same bean, quite a feat!
Glutton for great coffee that I am, I happened to have another Ethiopian Yirgacheffe from Metropolis on hand to research some summer coffees to recommend to Men’s Health Magazine’s Diana Stanczak for a coffee article she was writing. This coffee is almost as bright as Counter Culture’s Banko Gotiti, and to be honest, I wondered if I’d be able to discern a difference between two same-region coffees in an automatic drip machine. The KitchenAid Personal Coffeemaker brewed batches that exhibited some subtle differences, likely as much due to roasting differences as their growing and processing distinctions. This was actually the test that proved to me more than any other how fine is this brewer.
The KitchenAid Personal Coffeemaker is a winner. This is the machine I’ve been waiting for since their legendary four-cup, long discontinued. If anything, the new one is superior. The four-cup never attained the same brewing temperatures.
KitchenAid knocked it out of the ballpark with this one. Highly recommended.
This is as much a story about social media as a coffee brewer review. I first read about the Diguo TCA-C3 Siphon in a post by its Chinese manufacturer on LinkedIn. I was instantly enthused and invited them to CoffeeCON 2013. Next thing I knew they brought the spanking new brewer to CoffeeCON 2013, where is was a definite attention getter. The Diguo TCA-C3 is a glass siphon that makes three five-ounce cups of coffee. This is about one cup short of idea, but it’s perfect for a couple of cups of coffee.
Everyone’s calling them siphons but they have been known as vacuum makers for many years. The concept is: Water is heated in a sealed lower container. As it heats the steam pressure forces near boiling water up through the center tube into the upper bowl. The upper bowls mixes with grounds in as the pressure from the lower bowl keeps feeding it air bubbles, resulting in a nice agitation during brewing. When the heat shuts off the brewed coffee returns through a filter, in this case cloth, and the brew is hot, almost too hot, but beautifully extracted. Vacuum brewing is among my favorite methods. I chose it to demonstrate in my Coffee Brewing Secrets DVD released five years ago.
What’s new – The Diguo TCA C3 offers semi-automatic vacuum making. This is great because if you’re used to heating one up using an alcohol lamp, you already know how long it can take. The procedure with this unit is easy and straightforward.
How to use it – You simply put fresh water to the fill line in the lower bowl. Then turn the dial up to maximum to start heating the water. While it heats up, take the cloth-covered metal filter and install it, using the spring to secure it to the inside of the upper bowl’s tube.
At just over five minutes you’ll notice bubbling in the lower bowl, the water is at or near boiling. Once it boils, Lower the temperature dial to about half way (12:00 o’clock) and put the two bowls together. All this takes longer to write than to do. I’m sure I’m over communicating but after a couple of times you will find it easy to perform.
Once the bowls are joined and sealed, the water from the lower one will start rising into the upper bowl. Once the water has risen into the top bowl, add the ground coffee. Be a little careful if the coffee is ultra fresh as it may foam up and cause a messy overflow. If it does this, know that it’s happened to everyone who uses a vacuum method at least once.
The moment the grounds and water are in contact, start noting the time. Also start stirring the grounds and water together with the supplied stirring rod/scoop to facilitate mixing and to ensure the grounds all come in contact with water as soon as possible, as they grounds cannot being extracting their oils until they are wet. At just before 3 minutes contact time, shut off the heat power completely. The coffee will continue sitting up there and bubbling for around 10 to 15 seconds as if nothing’s happend – it takes a moment for the bottom bowl’s air to cool enough to contract. Then the finished coffee will begin its descent through the filter and into the lower bowl.
The coffee will be sucked back down through the cloth filter, hence the term vacuum. Once the coffee is completely down in the lower bowl, carefully remove the upper bowl (it is hot and may even be slippery) and place it in the black lid, which when turned upside down is a stand.
If all this was done right, it took a total of four minutes for your coffee to be extracted, perfect for the fine grind you chose. You are ready to enjoy your coffee.
If you’ve never had siphon coffee you’re in for a treat. Unlike drip method the grind is only used to expose more surface area. It does nothing to control contact time. Freed of this second responsibility you can experiment with different grind sizes to suit your palate. I use a quite fine grind.
My tests were performed with lighter roast coffees. I had Metropolis Coffee’s Sulawesi and reliably made many batches. It seemed each time I made three cups, a fourth person would show up and I’d make another batch, which allowed me to test consistency. Overall it was very consistent as long as I followed the same procedure and timing. I called it semi-automatic because you are required to shut off the temperature control when you wish to coffee to be done. I realize for some this will be a deal breaker. They are entitled but they are missing a much better cup of coffee, night and day superior to a Keurig machine and matching the best pourover.
A siphon cup differs from a pourover drip cup in the following ways:
- Hotter beverage temperature. If you like a steaming hot cup of coffee or find a Chemex cup too tepid to add cream, you’ll appreciate this.
- Heightens acidity, but never acrid-tasting. If you’ve found some lighter roasts too bright and acrid (sour) tasting you may find the higher overall brewing temperature of siphon brewers maintains the cup brightness minus that acrid note that I think is more pronounced when brewing at lower temperatures.
- The cloth filter matches the superclean mouthfeel of the best paper filter (think: Chemex) but with just that slight extra viscosity you can only get using cloth and that paper filter manufacturers keep trying to emulate doing things like poking micro holes into their filters.
The darkest coffee I used was Oren’s Sumatra. This is my favorite Sumatra Lintong ever from Oren. I was beginning to think he and I had a different idea of what’s perfect for Sumatra taste and then I took a sip of this coffee. Those who fear the siphon will be overlit or harsh due to the powerful air infusion during contact time can rest easy. It’s just a perfect cup. While I didn’t have anything resembling a French roast or darker during my test phase, I wouldn’t hesitate to try it out. However, if you’re a dark roast fan, I suspect you will find non-turbidity Presses or the Sowden SoftBrew will be more your cup of… coffee.
The last piece of maintenance advice is a bit of a hassle but I assure you it’s worth the hassle. Thoroughly rinse your cloth filter after each use, perhaps with a drop of Dawn or Free and Clear dish detergent just to enzymatically remove any traces of coffee oils. Cloth filters get rancid easily, their main drawback. You need not disassemble it. Keep it tucked away in a water-filled glass jar in the refrigerator. Never let it dry out.
Highly recommended to the coffee aficionado.
