Topic: Aeropress polyester explosion! (8 msgs / 181 lines)
1) From: Scott Marquardt
Well, it happened. I'm not the first by any stretch:http://www.coffeegeek.com/forums/coffee/machines/213214#213214http://www.coffeegeek.com/forums/coffee/machines/270012#270012
One of those incidents involved paper, one polyester.
Well, now it was my turn. At work today, I was (a) careless about how
far I turned the bayonet with poly in play, and (b) insane about how
hard I was pressing, for some reason.
The mess was ludicrous. It sounded like an explosion, and the first
thing you knew I felt heat on my hand (mild burns that were painful
for about 10 minutes), wet all over my shirt, and noticed that the
slurry had distributed itself all over the walls in the corner of the
company kitchenette where this occured. Miraculously, none of my
colleagues came in to see the mess while I was cleaning it up
[i]without benefit of paper towels[x], which were absent today. All
the countertop accoutrements were splattered with slurry. It was
insane.
But worst of all, I wasted some great Sidamo.   ;-D
Has anyone else had Aero explosions? And let me be quick to mention to
all that turning the cap on so that at least half the bayonet mount is
engaged is pretty darned important. And don't press too hard.   :-/
Wish I had a picture of that mess. A video would have been even better.

My worst Aeropress incident involved trying an inverted press but
forgetting to put a filter in the cap... that's what caffeine
deprivation in the mornings can do to you!

the clear plastic tabs for the bayonet mount on the cylinder of my AP  
appear to have some hairline cracks in them, I guess it's only a  
matter of time.  I would assume this is where yours failed?

So, just checking...
If I don't have poly filters, there's no point in risking a mess with the
inverted method, right?

Well . . .
I can't explain where your hairline cracks came from. The unit that
exploded on me actually suffered no damage. I suspect the bayonet
mount actually just slipped where I filed it. If I didn't have it at
least half-way on, the particular cap I had in play didn't have much
"flat" bayonet mating; only a few millimeters at most.
In short, the Aero and cap are fine, and I was (gingerly! LOL) using
it today without any problems.

That's pretty much true, IMO. However, MO must defer to the O of
others, who have apparently squozen some oils through the paper in
inverted fashion. I haven't explored that (see? doggonit, there's so
much room for discovery with this device for everyone, 'cause there's
such a huge space of possibilities it opens up -- I mean, c'mon
people: when was the last time anyone you knew used a French press
upside down? ;-) but it's certainly possible.
There may be merit. There are certainly risks. If you have a sense of
humor amid disaster, damn the torpedoes and forge ahead.

Dave,
I've been using a recycled gold mesh coffee filter screen in my AP, and
setting Rocky at #10, with very nice inverted results. I had a few extra #4
filters on hand and just cut the filter part out with an Exacto knife. Then
I traced the AP paper filter circle on to the screen, then carefully cut it
out with some sharp scissors. I grind very fine, and use lots of water.
On days that I don't want any extra fines in my cup, I just slip in an AP
filter. I also wet the filter with some water, before using it, as it clings
much better, and much less likely to slip or fall off. Without using the
paper filter, the amount of oils floating is insane, using both a screen
filter and a wet paper filter, reduces the amount by nearly half. Of course
these are just personal observations, I do not have access to the CSI lab,
and cannot give you an accurate ratio of coffee oils to water ratio...but I
can probably tell you what country the original green bean came from ;-)
