Interview: Ask Alan Adler About Flying Toys and the Perfect Cup of Coffee

samzenpus posted about 9 months ago | from the ask-me-anything dept.

News 76

When he's not lecturing at Stanford or NASA, Alan Adler is working on brewing the perfect cup of coffee and engineering flying toys. His AeroPress is one of the most popular coffee brewing systems available and one of his Aerobie Pro Rings set the world record for the farthest thrown object at 1,333 feet. Alan has agreed to sit down and answer any questions you may have. As usual, ask as many as you'd like, but please, one question per post.

Aerobie Drones? (3, Interesting)

CanHasDIY (1672858) | about 9 months ago | (#45705363)

After reading the article about the Aerobie setting a world record as the farthest flying thrown object in human history (uber-neat, BTW), I wondered: Do you think there's any way that such a design would work as a small drone platform? Perhaps something that can be thrown from the hand, then perpetuate flight at least semi-autonomously?

Re:Aerobie Drones? (1)

TheLink (130905) | about 9 months ago | (#45706435)

I think a boomerang was thrown further.

So my question is: what roughly is the maximum theoretical distance an unpowered flying object can be thrown by a top athlete? Assuming no wind, level ground and the usual stuff for a record.

If I were allowed one more question I'd ask what might be the optimum shape of that object, but nevermind :).

Anonymous Coward | about 9 months ago | (#45711723)

Where I'm from, further can be used for distance:
http://dictionary.reference.com/browse/farther [reference.com]

Usage note
Although some usage guides insist that only farther should be used for physical distance (We walked farther than we planned), farther and further have been used interchangeably throughout much of their histories. However, only further is used in the adverbial sense "moreover" (Further, you hurt my feelings) and in the adjectival senses "more extended" (no further comment) and "additional" (Further bulletins came in).
The expression all the farther (or further) in place of as far as occurs chiefly in informal speech: This is all the farther the train goes.

Will Aerobee do a Milk Steamer as well? (1)

billstewart (78916) | about 9 months ago | (#45708833)

I'm guessing the answer is probably no, because it's not something that's easy to do in plastic, and in a hotel room you can get by with heating the milk in a microwave, while there are other devices out there for stove tops or camping stoves. But I'd love to see one if there's a practical way to do it.

Cafestol? (4, Interesting)

Hatta (162192) | about 9 months ago | (#45705483)

I love french press coffee, but drink paper filtered drip because cafestol [wikipedia.org] present in coffee oils increases blood cholesterol. Unfortunately, those coffee oils are delicous so I lose a lot of the flavor as well.

I see the Aeropress is a french press like device, but uses paper filters. Doesn't using a paper filter remove most of the flavorful coffee oils you'd get from using a french press? If the Aeropress lets more of those oils through, does it also let more cafestol through?

Graphs with scales labeled in the appropriate units and measures of uncertainty(error bars) would be highly appreciated.

CannonballHead (842625) | about 9 months ago | (#45705695)

The whole cholesterol thing is bogus- they haven't proven that high blood levels cause disease.

Re:Cafestol? (1)

Hatta (162192) | about 9 months ago | (#45707555)

It's true that hypercholesterolemia may be a consequence and not a cause of cardiovascular disease. But that doesn't mean that ingesting substances that disrupt cholesterol homeostasis are safe.

Look at it this way. Assume that cholesterol is a consequence of cardiovascular disease. Cholesterol is then not a cause, but a warning sign that something bad may be happening. CVD increases serum cholesterol. Cafestol increases serum cholesterol. Could cafestol be a CVD mimetic drug? It's quite possible, and not something I'm willing to risk with my family history.

Pre-Roasted Coffee (1)

Cow007 (735705) | about 9 months ago | (#45705735)

What are your thoughts regarding pre roasted coffee versus roasting at home? (I personally roast at home with a popcorn popper and find that it produces better results at a lower price. The founding belief being that coffee being a chemically active substance after it is roasted makes it theoretically impossible to store roasted coffee and retain the original flavor since it can't be stored at absolute zero.)

Re:Pre-Roasted Coffee (1)

coolsnowmen (695297) | about 9 months ago | (#45708251)

The founding belief being that coffee being a chemically active substance after it is roasted makes it theoretically impossible to store roasted coffee and retain the original flavor since it can't be stored at absolute zero.

That is too simplistic of an explaination, because by that logic, no food could every be stored and retain the original flavor, ever. I'd love to see some analysis on how stable the flavenoids (-is that even the right word?) are in roasted coffee, vs our ability to taste the difference.

This is similiar to, I can up the resolution on my screen to 1 Terrapixel per square in., but, if my shitty human eyes can't perceieve the difference, does it really make a difference?

Re:Pre-Roasted Coffee (1)

Cow007 (735705) | about 9 months ago | (#45708625)

Invalid argument. The coffee is chemically active so the flavor CHANGES after a short amount of time. If you have not had coffee just roasted and tried it over a period of days you would not know the difference. The easiest way to describe is that it gets mellower and less sweet. As to weather it really makes a difference that is subjective. If trying to brew the PERFECT cup of coffee however then it definitely makes a difference. Coffee being discovered in Ethiopia tends to give enormous credibility to the practices and methodology of Ethiopians regarding coffee. The initial period of 12-24 hours for degassing, standard practice among europeans is ignored since all the coffee is used right away. This mostly applies to bubbles that foam up during brewing but coffee that has not degassed has a wilder flavor also. In practice at home I usually use it within 2-4 days but after 5-7 days it is not the same. as before of directly after the 12-24 hour period; first getting mellower and then towards bitter.

Re:Pre-Roasted Coffee (0)

Anonymous Coward | about 9 months ago | (#45711121)

What does "chemically active" even mean? If a food wasn't "chemically active", you couldn't eat it. All foods are "chemically active".

Re:Pre-Roasted Coffee (1)

Cow007 (735705) | about 9 months ago | (#45732983)

Means that changes are occurring. The roasting process creates unstable compounds that change over time. The chemistry of coffee is extremely complex, I don't pretend to understand it all...

Aeropress vs. Clever Coffee Dripper? (1)

khb (266593) | about 9 months ago | (#45706519)

I've long enjoyed my Aeropress for travel. But for the office/cube I've usually used the Clever Coffee Dripper (http://www.sweetmarias.com/clevercoffeedripperpictorial.php) as it produces as good (or better IMHO) results with a little less excitement (misalignment of the Aeropress considered harmful ;>). At home I alternate between espresso and various other techniques.

Do you consider the Aeropress the pinnacle of coffee brewing, or just a really good portable approach? Are you working on any further improvements?

Metal filter for Aeropress (2)

hawkinspeter (831501) | about 9 months ago | (#45706597)

I've been using a metal filter with my Aeropress(es) for a few years now and was wondering if you're ever going to sell a version with a permanent filter? Also, how about a redesign to make the upside-down method a bit easier? (The upside-down method allows for better control over the steep time).

Re:Metal filter for Aeropress (2)

ottothecow (600101) | about 9 months ago | (#45711401)

I've given up on the upside-down method.

Instead, I just barely insert the plunger immediately after stirring and topping off the water. A bit of coffee drips out, but for the most part the plunger forms a vacuum that holds the coffee in the chamber.

With it like this, I can leave it to steep for a decent amount of time without having to bother with the inverted method.

Re:Metal filter for Aeropress (2)

hawkinspeter (831501) | about 9 months ago | (#45712113)

The metal filter I used to use was a home made one (from a SwissGold drip filter basket) that allowed too quick a flow, so inverted was the only way to keep the water in contact long enough. I've since upgraded to an Able Brewing filter disk that works a bit better. The inverted method also allows you to slowly pour on the water and give it a really good stir - it's slightly trickier, but gives a lot more control over the whole process.

Re:Metal filter for Aeropress (1)

dwpro (520418) | about 9 months ago | (#45717317)

I typically use a fine grind and a bit of tamp on the coffee grinds so that it requires pressure to push down the coffee, somewhat more like espresso. I really like the results.

Aeropress Longevity (1)

Anonymous Coward | about 9 months ago | (#45706659)

I love my Aeropress, in fact I'm on my second one. However my experience has been that they only last about 2 years. Your company was kind enough to supply me with a replacement when I noticed vertical cracking in the brew chamber, which I thought was causing slippage of the plunger as the gasket entered the weakened chamber.

But the replacement suffers from the same problem, so I'm guessing the gasket has worn down over time too.

Even at two years, the Aeropress represents a great value for making great tasting coffee. But I'm wondering if you had any plans to address these issues or if they're just a limitation of the materials.

Re:Aeropress Longevity (1)

hawkinspeter (831501) | about 9 months ago | (#45706773)

I've been using the same Aeropress for more than a couple of years without any cracking in the plastic. The only problem I had is when the rubber plunger started to breakdown after being left on sunny window-sills for too long. Luckily, it's possible to buy the rubber bung separately now, although I just bought another Aeropress so that I've got spares for the other bits.

Re:Aeropress Longevity (0)

Anonymous Coward | about 9 months ago | (#45711155)

How about a real espresso maker? (2, Interesting)

Anonymous Coward | about 9 months ago | (#45707553)

I believe before this decade is out America should produce a device that shoots water through coffee at a controlled temperature and pressure. I believe it should be possible to disassemble and clean it much as you would a firearm. I believe it should cost less than $100, and be manufactured here. I don't care if the robots that manufacture it are made in China; but I want it made here for quality control purposes and I want the beverage contact surfaces to be stainless steel or some other metallic surface that doesn't contain lead, plastic, or other questionable materials. It should use no consumable items other than coffee, water, and fuel. I should not have to buy another one after just a few years. It should show up in antique shops 100 years from now, like the counter-mountable meat grinder I saw a few months ago.

Milk frothing is not a requirement. Milk is for children.

I don't think I'm asking too much, and yes, the "I believe" format of this request is a take-off on Kennedy's Moon speech.

I've done the upside down method a few times, and I also used my Aeropress to filter the coffee from some homemade coffee liqueur a few summers ago -- did a great job of that.

So: You have all the chance in the world to experiment; do you have any suggestions or favorite ways to use an Aeropress besides the package directions? Do you typically use it in any way different from the standard instructions?

Slight redesign for more compact storage? (2)

chriskenrick (89693) | about 9 months ago | (#45710145)

Loving my Aeropresses (office and home), but one thing bugs me slightly. If you lock the end cap on for storage, the rubber bung part can only be stored inside the tube, which causes it to degrade more quickly. If you have the rubber bung protruding past the end of the tube, the end cap obviously doesn't fit on. Could the design be slightly tweaked in some way to allow storage as a single piece without degrading the bung?

My Aeropress Experience (1)

jerel (112066) | about 9 months ago | (#45710245)

As a credentialed geek who loves coffee, I of course purchased an Aeropress straight away upon hearing about it. I used it every day for about a month, experimenting with type of coffee, grind, water temperature, and pressure/amount of time pushing the water through. PROS: It's easy, and the coffee is good. No reason you can't make a delicious cup of coffee with this once you nail down the perfect combination of the above 4 things. CONS: (And this is the reason I stopped using it.) It uses a LOT of coffee to make one good cup of coffee, more than any other method. Your usage will just about double per cup over other methods. The other drawback for some is that it only makes one cup at a time and then you have to reheat the water while you clean it and refill it etc. for the next cup. My recommendation: If you've never tried a "mocha pot" stove-top espresso maker, give it a try. (They have electric ones too but they cost a lot more.) Of course the easiest and simplest to use and clean up is a simple cone filter over a carafe. Many people swear by the taste and simplicity of a French Press pot, but they are a little messy. Enjoy the journey!

Re:My Aeropress Experience (1)

dwpro (520418) | about 9 months ago | (#45713453)

I found that by getting a metal filter [amazon.com] and tamping a fine espresso grind down I can use far less coffee and get a very good cup, thought it takes a bit of elbow grease to push it down. I've also found the metal filter to be even easier to clean:

  • run the cap and filter under the sink after pressing out coffee while press cap still attached to clean the filter and cap and to mostly separate the metal filter from the grinds
  • remove the cap and metal filter. Rinse, leaving the filter inside the cap and set it aside to dry
  • dump the grinds
  • rinse the pump and separate, and set aside

I love the aeropress.

What's AeroNext? (1)

timothy (36799) | about 9 months ago | (#45710579)

Both the Aerobie and the AeroPress embody design traits I really like: they're durable, have few pieces, and work simply by dint of ordinary (vs. extraordinary) human-muscle power. Basically, they remind me of simple machines. (As in the wedge, the lever, etc.) What are your favorite likely areas for further improvement?

Will you come up with good improvements on ...
- Flashlights? (Muscle-powered flashlights have gotten much better, thanks to LEDs, but they still mostly suck.)
- Sailboats or kayaks? (What could modern materials and thinking bring to small person-powered / wind-powered watercraft?)
- On that front, paddles / oars ... wrt ergonomics and efficiency, I think there is a long way to go ...
- Whistles? (Pealess whistles have come a long way, but progress isn't over)
- Waterguns? (Where is the next SuperSoaker-style leap?)
- Bicyle fairings? (A semi-standardized clear fairing would be useful for lots of people, esp. as some big U.S. cities improve their cycling infrastructure.)
- Juicers? (A human powered AeroJuicer sounds like a good idea to me ...)

Not to say that for any of the above items that there aren't smart people working in the field ... but Hey, there were lots of coffee makers and coffee making methods before the Aeropress, too.

p.s. What about smaller and bigger AeroPresses, for light travel and for bigger gatherings? :)

I need to brew enough coffee to fill an Olympic-length pool. I was planning on inviting the Paris metro area over for a cuppa, if you must know. I know that I'll need about 105 metric tons of coffee (~$200k) for this adventure, but the coffee pot I have is a bit undersized for the task. Any idea how one would go about generating that much java?

Say! I'll need somewhere to keep it, too! It may take quite some time to serve coffee to that many Frenchmen. I am sure there would be time for high society to snub the endeavor and for a mob of cafe owners to lynch me before I was halfway through, but in the hypothetical meanwhile I'd certainly want some way to keep the coffee hot. I understand that there are active heating methods both ancient and novel, but I'd like to keep my operating costs down. What kind of container could I put it in? What is the longest amount of time I'm likely to be able to serve hot coffee to Frenchmen?

Yours,
