Aeropress: Little Coffeemaker that Could

Aeropress 1 The Aeropress marks the longest I’ve ever waited for formally review a product. I met inventor Alan Adler nine or more years ago. We were introduced by then Bunn VP Aimee Markelz. Just to show how gracious some people can be even in an industry with such hot competition as coffeemakers, Ms Markelz was walking through the International Housewares show before showtime and spied this new coffeemaker. When I did my usual walkaround at Housewares she handed me a slip of paper with the Aeropress booth number on it. She told me she thought I’d find it interesting. I did. I do.

The reason I waited so long to review it? I guess I took it for granted. But now I feel a little guilty and negligent. Or it’s such an open-ended device it all depends on how you use it. Honestly, I can’t tell you why. Is it because it has no engine, no water heater? That can’t be. Neither does the Sowden SoftBrew nor does the Chemex. Is it due to it’s cost – as in low? Nope, I’ve reviewed the Melitta single cup, and I’ve packed three of them into knapsacks of my college bound sons.

So, let me stop the self analysis and proceed to make amends for my lengthy review time. The Aeropress, though wholly innovative and original in its design, seems to provide the features of all the world’s coffeemakers through time. Like a modern Hollywood film, it has elements of all that came before it in its genre. The Aeropress has some elements of the French press, namely the press, both in name and procedure. The Aeropress has elements of the Chemex, particularly in its filter and its brewing temperature recommendations. Finally it has elements with the vacuum or siphon coffeemaker, mainly its mass-compressed grounds puck.

The Aeropress is perhaps the ultimate flexible coffeemaker. It can be used conventionally, where it gives the impression of being a somewhat leaky manual drip maker. It can be inverted, placed upside down, its filter cap removed and it becomes a settling tank where coffee is steeped like a tea before its cap is replaced, it is flipped over and then pressed to completion. Which is it for me? I’ve spent several years in each camp. Finally (or just lately?)

I’ve settled on the conventional method. I believe I’d done this out of simplicity, and perhaps a little out of my desire to set the record straight on what I consider the Aeropress myth of being a leaky drip maker. When people pour a little hot water into the Aeropress and stir so that the grounds get plenty wet and are allowed to swell and settle before the press is used, a minute amount of water travels through the grounds and out through the filter and into your cup. There is nothing about this that is going to affect your coffee end result. It is no different than the initial drips of any drip coffee maker. Coffee is all about grounds/water contact time and nothing else.

Aeropress brewing temperature is, or should be, controversial. I know it’s manual so you can use whatever your lil’ water heatin’ vessel can provide. I have a fancy schmancy BonaVita kettle with dial and hold temperature settings. Inventor Alan Adler says Aeropress competitions tend to be won at brewing temps of 185°F for the super light roasted coffees and 175°F for medium to dark roasts. What does all this mean to the coffee industry, who’s fought so long and hard to convince us to brew hotter into their 10 degree (195F-205F) window? That’s a tough question and likely a subject for a different article. For the moment I’m going to use the ole’ reviewer copout #7 that we should view the Aeropress on its own terms. Of course you can use your Aeropress at whatever temperature you prefer, but after a number of tests in my kitchen, I’m inclined to operate mine at the light roast winning temperature: 185°F.

Speaking of roasts, here are some coffees that I tested:

  • George Howell Coffee’s La Minita I got spectacular results with this coffee. Man that is one complex beverage as brewed in the Aeropress. Like a great symphony orchestra, La Minita’s Bill McAlpin is unable to create a bad note. This coffee, third wave light roast and all, is just a perfect match for the Aeropress. Did I hear chocolate? I know most coffees give this note at this brewing temperature, but it’s the quality of chocolate note that this coffee provides.
  • Sight Glass Colombian Finca Alcatraz – I recently became smitten with this coffee in all brewing methods. I don’t know what to say except I just enjoyed its richness and cocoa and nougat notes. I admit I feel the lush fruit notes are boosted by moving the brewing temperature back into the 190°s.
  • Counter Culture Finca El Puente Honduras – I couldn’t resist trying some coffee farmed by CoffeeCon presenters Marysabel Caballero and Moisés Herrera and their latest coffee. Counter Culture roasted it at the light end, although to be fair, not too light, which I found to be a perfect match for Alan’s observed 185°F brewing temperature. Okay, I probably sneaked up to 190°F. I got that black cherry flavor kick right away.

Conclusion: The Aeropress is just a wonderful brewer. If you are caught between gigs, you likely can afford it. It is easy to use, to clean up. And, it delivers an ultra clean taste, with plenty of viscosity but virtually no sediment. If this is the cup you seek, the Aeropress is a brewer used must have in your brewing arsenal. Period.

Photo note: Aeropress Inventor Alan Adler says, “I do like clear glass which reveals the flow (drip), but recommend a wide-bottom, sturdy mug like the attached pic.”

Alan Adler recommends robust glass only.

 

 

 

 

Should you Jump on the AeroPress Coffee Bandwagon?

Much like Coffee Kevin, our crew tests and evaluates every brewing gadget large or small and we share our feedback. Some equipment is strictly for commercial use: Does anyone need 240 cups of coffee per hour at home? Maybe, it depends on how many coffee drinkers live with you — I know that I could put a serious dent in that! Some coffee crazes easily translate from commercial cafes to your kitchen counter, yet due to sheer volume or prohibitive cost, some do not.

In conjunction with the World Barista Championship that was held during the Melbourne International Coffee Expo in May 2013, another (much quieter!) competition occurred: The World AeroPress Championship. Now here’s a coffee trend that everyone can try on for size. The initial set up for this brew method runs about $150 for an AeroPress coffee maker, pack of filters, variable temperature kettle and kitchen scale. All you need to bring to the kitchen table is a little caffeinated curiosity, your coffee and a cup.

Here’s a look at the winning “recipe” from barista Jeff Verellen of Belgium. We were interested to find out how it tasted compared with our standard AeroPress brew, so we tried it ourselves. Here are the steps we followed:

• 17 grams of coffee or espresso ground slightly coarser than drip
• Rinsed paper filter
• AeroPress in regular position (some people use an inverted technique)
• 50 grams of water at 182F for the bloom
• Bloom for 40 seconds
• Nicely wet all grounds and lightly agitate it
• Very slowly add 215 grams of water at 175F for about 30 seconds
• Press very gently for about 30 seconds

Jeff mentioned he favored bolder coffees for use in the AeroPress so we chose a flavorful espresso blend that we regularly enjoy. 17 grams corresponds to about 1 rounded AeroPress scoop, but we weighed ours to be certain of the measurement. His grind, however, is somewhat controversial: Unless something was lost in translation, he reportedly used a coarser grind than drip, while conventional wisdom has the grind somewhere between espresso and fine drip.

Water temperature is not what you’d expect either. The familiar 200F temperature threshold is not achieved and it still creates a proper extraction. You can experiment yourself to confirm this. With a variable temperature kettle it is easy to get the right (lower) temperature for extraction. You could also use a regular kettle with a glass measuring cup and an inexpensive drink thermometer. We placed the AeroPress over a double-wall glass mug and it was beautiful to watch and listen to the resulting coffee droplets. In about five minutes, we had a single cup of coffee with the AeroPress from start to finish. The aroma was a little more subtle, but the coffee was smooth, even and full of sweet caramel notes — just as we had hoped.

Then I compared these delicious winning results to my co-worker Jess’ morning AeroPress coffee habit:

• 34 grams of coffee ground slightly finer than drip (2 rounded AeroPress scoops)
• AeroPress in regular position
• No filter rinse, no pre-infusion
• Fill to the (4) measure with water around 185F
• Nicely wet all grounds and use the included stir stick
• Wait 30 seconds
• Push down hard with even pressure, about 30 seconds

The included AeroPress instructions indicate for two scoops to fill the tube with water to the (2) measure and to make a concentrate rather than filling to (4) with this dosage. The resulting concentrate can then be diluted (as if!). Even with her predilection for up-dosing and lack of dilution, she brewed a cup that was not bitter or sludgy. You have to love a device that still operates well whether you follow the printed directions or not.

Besides price, taste and ease of use, there is also the portability factor: It is lightweight and virtually unbreakable. The AeroPress is a practical option for anyone who would like to take his or her fresh cup of Joe on the go. I have heard tales of AeroPress prepped successfully in campgrounds and college dorms — even on a commercial airliner mid-flight! The aftermath is also manageable to clean because the spent grounds are pushed out after the extraction and it is fairly solid like an espresso puck for easy disposal. A quick hot water rinse and occasional soft scrub are all that is required to clean.

While any coffee brewing method can be taken to scientific extremes, the versatility of this simple plastic device continues to amaze. Right side up, inverted, pre-infusion, paper versus metal filters –you can try all of the tricks of the trade to see what tastes best for your coffee or espresso blend. What I’ve outlined here are just two of a seemingly endless number of variations.

The AeroPress is fun to use and that should come as no surprise since it is from the same Stanford inventor behind the Aerobie Flying Disc. While it may be easy to dismiss the device based on looks (think Habitrail meets water pipe), it makes a seriously good cup of strong coffee. Recently, my local cafe started offering house roasted single origins prepped via AeroPress; I can’t think of a more glowing endorsement from the world of specialty coffee. For home or cafe, the AeroPress is here to stay. Don’t knock it till you try it!
