Keith has a new filter product for the Aeropress:

I am a daily Aeropress user.
So I am waiting to hear some feedback on whether
this is a worthy replacement for the paper filters?
Or, is it a better option then the poly filters some were using?
I guess I will have to buy one so it can appear in my Xmas stocking
on the 25th!

It sounds like a useful toy, but I'm tired of having pieces to clean. A good paper filter that's properly rinsed is good enough for me!

Or, even better, a trimmed Hario vac-pot cloth filter that's properly rinsed.

I just want a clean, lint free, and disposable filter. If it has to be reusable it must be as easy to clean as my Cory rod. Anyone with an espresso machine knows that inevitably the user will be sitting at the table with a dental pick, cleaning out the hundreds of plugged holes.

That's just not my cup of tea coffee!

I'd like to try the Coava but like you I don't want to have to do a bunch of cleaning after each use.

Gotta say though, in my years of espresso I've never had to clean out plugged holes with a dental pick, ever - that's what backflushes and cafiza is for. Don't want to detract from the thread, just don't want anyone to think it's inevitable you'll need a dental pick and hundreds of holes as an espresso machine owner.

You're right, a good maintenance program alleviates most of the problem. But, you'd be amazed at the gunk I find in supposedly knowledgeable user's equipment. :icon_puke_l: I'd bet that 90% of users don't backflush with a strong detergent; besides, only machines with 3-way valves can be backflushed.

Back on topic: It just seems inevitable that coffee grounds & fines will get jammed into the holes of this filter.

I like the idea of a permanent filter (earth friendly and all that), I just don't like the cleanup. The AP can be cleaned for the next use by wiping it with a paper towel or napkin. Adding something that'll need scrubbing is counter-intuitive.
Title: Re: Coava disk filter for the Aeropress
Post by: peter on December 09, 2010, 11:18:16 AM
The reason for the Coava disk is for those who find paper filters trap too much 'goodness'.  If someone's happy with paper, there'd be no reason for one of these.

That said, after using a Kone for a few weeks now, I don't think clean-up for the AP disk would be an issue.  Whatever coffee particles get lodged in the holes tend to rinse out fairly well.  A lot of that would be grinder-dependent I suppose.

I'm a strict adherent to the rasqualator/polyfelt cult, but secretly, only use my AP a few times per year.

And not to change the subject, my Kone is going up for sale too.  For so many years, my rut included a presspot that I just can't make the switch.

I liked the rasqualator felt solution a lot but sadly it disappeared during one of our moves. I'm back to the Aeropress paper filters now. Truthfully I find myself doing more Melitta one cup pourovers rather than Aeropress... when I'm not pulling a lever. ;-)

I occasionally use the AP, but I've discovered that my many-year consistent use of it, hitherto, was an exilic habit while awaiting a redemptive pourover.

With the Hario now on hand, I use the AP far less often. It probably makes just as good a cup, but I've always preferred pourover as a technique.

I tried out the Coava Disk this morning and I'm happy to report that I really like the cup it produced.  A very nice sweetness & clarity came through and the cup was decidedly better than using paper filters. Clean up is very easy as well - just a quick rinse under the faucet and its good as new. Definitely worth a try if you're an AeroPress user.

I can't figure what's earth-friendly about the steel. It takes a lot of carbon to make that steel, and putting paper filters in landfills sequesters carbon (part of my entire theme that we should increase demand for any disposable carbon-based product that requires little energy to manufacture, and see to it that it's properly deposited in one of a vast number of landfills ;-)

Not to broach a hot topic; I just don't think it's possible to know enough to be content, with warrant, that either alternative is in the long run somehow more or less responsible for making things better or worse.

For me, the alternative to being more certain than is warranted is not to not give a rip, it's just to be content with not knowing.

There was never a recall but I did end up contacting AP corporate HQ in the hopes that they would be so guilt ridden at the potential health hazards I may have been exposed to that they would send me a free AP. Not so lucky:

Quote from: Aerobie Co.
If the AeroPress is a milky blue color then it is not BPA free. You can purchase a new chamber and plunger BPA free for $19.50 from us. We had a out side lab test for leakage of BPA into the coffee and they found no BPA in the coffee useing the milky blue color AeroPress.
Title: Re: Coava disk filter for the Aeropress
Post by: rasqual on December 16, 2010, 11:54:09 AM
Personally, I don't think using an Aero that's BP-free is a big issue because I'm not diligent in scrutinizing all other plastics which not only may be in my hand with food I purchase, but behind the scenes in processing of various foods.

Is BPA illegal for use in food processing?

Not to further confuse thinking things out with blatant rationalizations,  (I know I don't like to throw stuff away) but unless the energy/resources required to clean the coava filter is greater than the energy/resources used to manufacture, package, transport, and dispose of each of the paper filters, wouldn't the coava filter eventually be ahead?  Admittedly, the number of uses might be pretty high before break even  ....

I recycled a twenty cent scrap part to make one of these - my Aeropress was used
too so no BPA's were harmed to create my set up. The metal looked like a roll of 35mm
film with round holes on the each side. It appears to be a strip cut from a long coil
that is then trapped in the white plastic (and probably BPA laden) body of this juicer part.

OK, I picked up a Coava disk and that settles it -- I won't be getting a cone.

I have no idea why I occasionally abandon what I know in the vain hope that simple physics working against the cup's quality will somehow have morphed, since the last time I personally experienced it in action, into magic working in its favor.

If the holes are as big as these are, there'll be sludge in the bottom of the cup.

And there is. A ridiculous amount.

The cup tastes fine. But if I want Turkish coffee, I can brew that.

Yuck.

I've been using the disk for about a week now and I have to say that I like it. I did get more sludge than I would have liked with my normal AP grind, so I went a bit coarser with my grind. Still a bit of sludge but not enough to worry about, and it produced a better flavor IMHO.

I take a standard drip grind from a commercial Bunn grinder, drop in the Aeropress fitted with the disk, and pour in hot water.

Immediate, substantial wash-through in the Aero, with a lot of fines.

They do not magically disappear during the remainder of the brew process.

I do not wish to attribute a disoriented state to anyone claiming they get no fines from the disk, but I shall gently remind my patient reader that the first of April is some months off.    ;D ;D

I am not sure if I have the inverted technique down pat (but I am having fun practicing) but with the speed the liquid leaves the Aeropress using the perforated disc, I wonder what advantage I am gaining over a standard pour over with regard to extraction - my pressure plunge at the end is not meeting much resistance compared to a fine grind and the stock paper filter.  I will try the felt next - this disc is a bit of a let down.

Disclaimer - I am not using the Coava product. It is similar though.
Title: Re: Coava disk filter for the Aeropress
Post by: rasqual on December 28, 2010, 11:47:06 AM
Inverted with the disk? Interesting.

The main advantage of inversion, I think, is that the bloom is the first thing to go through the filter, instead of the last thing to go through the puck. Thus, bloom-borne oils that would otherwise end up mired in the puck are quickly dispatched to the cup.

I'll have to try the disk inverted. Not with me today, alas.

I do agree that the poly is the overall flavor contender; a clean cup and full flavor. But the Disk wipes the floor with the poly when it comes to the cleanup round.

Thats about the only way it works well that I have found is inverted with a course grind almost to press pot 2 min. seep  then press very gently. Made a geat cup. The first time I had the Vario set way to fine and well you needed rubber boots to wade thru the muck. We use the Aeropress almost daily at home for the first cup. The problem I see is at 4:30 a m is not the time to invert anything  ;D. I can already see it flying across the kitchen or popping the disc in the trash on trash day  :(. My wife say's passssss

So I will to someone on the list

2 min. seep

Good point. Inverted after a wait, the grind has swelled and fines that would otherwise pass now won't. Some still will, but far fewer.

Forgot about that.

That also explains the insane fines wash-through I had instantly upon pour.

This does not explain javaman's results, which I suspect involve dark arts and forbidden conjurations.   ;)

Post by: thejavaman on December 29, 2010, 04:36:11 AM
I use a Saeco Titan grinder set just a touch finer than drip. I always use the inverted method in any of my AP preparations. My procedure is very similar to STEVE LEIGHTON'S WITH HAS BEAN (http://www.hasblog.co.uk/wp-content/uploads/2010/09/aeropressguidemini1.jpg) with the exception of me obviously using the Coava Disk instead of paper filters and me also adding a small amount (~2 oz.) of hot water to the inverted AP chamber prior to me adding my coffee, I then add the rest of the hot water and stir the "slurry" to promote an even saturation of the coffee grounds.  I also push very quickly with a very light, yet consistent pressure on the chamber and I always stop before I completely compact the coffee grounds (right before the "hiss").

I'm sipping a cup (made how I just described above) as I'm writing this and I'm thoroughly examining it to see if I can detect any fines or sludge (or to just see if I'm crazy  ;)), but I'm still coming up negative on both all three fronts. Sure, the cup is "oilier" compared to using paper filters and there is a "oily swirl" near the bottom of the cup, but I do not get little bits of coffee grounds floating around or any "muddy sludge" at the bottom of my cup like a French Press.  No "magic tricks" here, just a really good cup of coffee....

Apologies for digressing from the main topic, but I've seen BPA mentioned so much during this thread I wanted to chime in.

I have some experience woking with plastics and can tell you that the old aeropresses were made from polycarbonate. While this does contain BPA (no phthalates) it does not leech. So those folks with old APs are safe.

Aerobie made the move to BPA free copolyester because of the *perceived* risk with polycarbonate. Smart move.

If you're still thinking about dumping your old aeropress, feel free to send it to me.

Again, my apologies for the interruption.

Interesting to follow the discussions on the AP over at Coffee Geek.  The Coava filter has sparked some mild renewed interest in using that *plastic* prep, aka Aeropress.

Ceramicly,

Used my AP with the Coava disk for the first time this afternoon.  Minimal fines in the cup.  And it was perhaps the best cup I've ever had.  Chad's Colombia Tolima was the coffee.

Wondering if the old FP has a place in the cupboard any more?

Double disk - time to choose

008 : Smaller holes and slightly thiner material - We find it to produce a lighter mouthfeel with very clean and hardly any fines/sediment

010: Larger holes and slightly thicker material - A bit more pronounced body and richness with a bit more fines/sediment. Slightly easier to clean.

These guys are slick... once a month toss out a new variation.... us Caffeinatics will jump at their bait. 

First the Kone, then Kone with a Chemex, then the disk, then the disk with an aeropress, now another disk... (which I want)

Mark my words, we will next see a single or double portafilter basket.... then the other one, then a vacpot filter..... where does the madness end?

I know this is an old thread but with my pressurestat acting wonky I wanted something to distract me while I wait for the CEME replacement. So this afternoon I picked up a Coava disk filter for the AP at a local coffee shop. Tomorrow morning is the first run at it.

The last batch of my Panama Elida Natural that I had roasted in hopes the Jaeger pressurestat was going to be 'the one' turns out to be the coffee this morning for the Coava disc. Gotta say, this was a fantastic Aeropress cup.

Not sure if it's always going to bang out great coffee, or I got absolutely lucky choosing the best grind/dose, or whatever, but the cup I just finished was seriously good.

As you can see this is a number 008 disc and I got almost zero fines in the bottom of the cup, a minuscule sprinkling, almost too small of an amount to mention. I had a Kone yesterday in a retail shop which produced quite a bit of sediment in the bottom of the cup but the cup was really, really good - a Kemgin: https://www.philsebastian.com/coffees/kemgin-wellega-ethiopia (https://www.philsebastian.com/coffees/kemgin-wellega-ethiopia)

This image is post-brew, I just quickly rinsed the disc (5secs) and dropped it back in the base for a quick photo.

Or more interesting....I'd be very curious to know how that same coffee compares in a FP.

No poly, but I'll whip up a paper AP using same dose/grind/bean/technique and let you know in a few mins.

I really like my coava disks and I use them 3-4 times a week. Depending on the bean/roast, I switch back and forth between the 010 & 008 disks and I've yet to have a "bad" cup from either.
Title: Re: Coava disk filter for the Aeropress
Post by: staylor on April 14, 2011, 11:46:30 AM
Ok, with the caveat that I've only brewed a single coffee with the Coava 008 disc and only done one paper comparison against it, I'll put my opinion out there...

1) I think the Coava disc is easier to use, no risk of paper tear on a pre-rinsed paper filter.

2) I like the precision of the Coava disc, just drop it in and it's perfectly aligned.

3) I like the 'feel' of it - precision, digital.

4) I like the idea of it's 'inert interaction', a slick surface with evenly spaced holes and repeated sizing the disc doesn't get in the way of the process it's just part of the process.

5) The Coava disc allows better release of oils and such and this presents itself in the coffee, I feel like I'm getting a full representation of the bean as compared to the paper.

Random points off the top of my head. Now for the more important opinion, how did it taste? In a word - better.

Other words that came to mind - rounder, fuller, more complete, better body, unfragmented, in-tune, more flavorful, synchronous, full stage presence, etc.

If someone offered me the Coava AP disc mug and the AP paper filter mug side by side I would have drank the Coava mug and left the paper filter mug.

But like I said, this was only a 1 to 1 comparison and there are many reasons this result could have turned out like it did. For now the 008 has me very interested in the possibilities and I'm going to play with it a bunch more while waiting for my CEME pressurestat to show up.

If both of those fail there is always pushing the start button an a regular drip brew machine.
