Topic: Yama / Cona Vacuum lock ! (15 msgs / 360 lines)
1) From: William Hoffman
Good Day All,
What caused this and how do I prevent it from happening again?
--------------------------------------------------------------
I was making 24 fluid ounces of coffee with my Yama and Cona Drainer.
The going South phase froze at 6 ounces.
I tried to thump the Cona Drainer to restart the flow but it was locked
down solid.
I tried to loosed the top bowl but it was set solid.

The Yama bottom bowl just imploded while cooling on my stove.
Help! What caused this?

William;
	Having fought the Cona Wars I can offer you several pieces of advise.
	1) Make sure there is NO chaff remaining in the beans
      1a) you might substitute a commercial coffee just to verify the grind
not being the problem
	2) Make the grind a notch larger
	3) Allow the coffee to remain up north for a FULL two minutes
	4) When you clean the rod, make sure you use soap and water on the disk
underside.
	It can be a bit frustrating trying to figure out just what isn't right -
but if you hang in there and go through all the tweaking - eventually you
will get a pot of coffee.

William,
You and John, bad for the vac business, LOL!
We spent weeks trying to figure out why John's Cona would stick.
I purchased my Cona Vac in the Spring. The first time I used it it stuck. I
have no idea why, but have not had a problem since. I even use a setting 4
on my Solis 177.
I don't know how long you have had the Cona glass rod but it would be
interesting if you and John have received rods that are different from mine.
But you are definitely having problems with water getting by the rod to head
south. My rod has little bumps where it seats at the bottom of the bowl.
They are hardly visible (especially with my eyes).
I also pre-boil the water before putting it in the lower bowl and lighting
the lamp.
It's an awesome cup of coffee when it works!

I use a yama with the regular cloth filter. I've never had a problem. So many people use the Cona filter and have problems. What is the advantage of the cona filter that makes the attending problems worth working through?

The first advantage is you never have to replace the filter, unless, of course, you break it. With glass there won't be any added taste. With cloth or paper they can accumalate added flavors until they are changed. Even washing they can't be as clean as glass. Plus, it's cool and amazing to watch, very entertaining. People can't figure it out!

Steve Shank;
	Be careful - Steve Trescott is the silver tongued devil that talked me into
buying my Cona in the first place.  I think he owns stock :O)

problem. So
<Snip>
advantage of
<Snip>
through?
I won't speak to the Cona in particular since I don't own one,
but I do own several other glass filters.  I liked the Yama
cloth filter, but I like the glass filters much better.
Glass filters are much easier to clean.  They let all of the
coffee oils through.  They look very cool.  They store inside
the glass globe of a vac pot and not inside a container of
water inside my refrigerator.  They are great conversation
pieces.  And, reason number one, I've never had any
attending problems with glass filters.

Thanks John. I'm not sure if my tongue is silver...
I don't know even know if the company is public but it's frustrating to hear you are still having problems with your's. Mine is awesome. I use it every weekend.
Maybe I've been blessed :-)

At least I know why people mess with it. I have found no extra flavors from my cloth filter, but perhaps I'll mess with the cona filter when I feel like taking up a new hobby.

Your Cona drainer clogged while there was still a vacuum in the bottom.  The
cooler it got, the stronger the vacuum until the little yama yelled mama and
gave up the ghost.  The cloth filters are *much* better.  Use 'em.  ;^)

In this case, the filter rod outlasted the pot!

Maybe if you and John took digital pics of the bottom of your cona rods (the
part that sits on the glass and does the filtering) we could see if the
height of the bumps are different or something.   I'm sure someone would
donate the web space.
