Topic: Cory Rod in a Yama Vacpot? (8 msgs / 158 lines)
1) From: Bob Hazen
I am continuing my vac pot experiments.  Following the list's advice, I've made some nice gains in flavor.  I'm using a Cona rod which has a fairly smooth filter area.  Looking over the Cory rods on eBay, it appears the filter area is rougher than the Cona.  I'm thinking I may get a better draw-down with the Cory.   A couple of questions for the list:
Are there different models of Cory rods?
Which models, if any, will fit the small Yama pot?
Thanks a bunch,
Bob

Thanks for the kind offer, Rich.  I would take you  up on it, but I went 
ahead and bought one off ePay.  It will be interesting to see how it 
performs in comparison to the Cona rod.

I'm using a 5-cup Yama.  Good to know it will fit and I didn't waste my $12
:-)
My earlier experiments with the vac pot left me non-plussed.  My recent
success with finer grinding is re-kindling my interest in the vac pot.  Who
knows, there may be a Technivorm for sale sometime soon!
I'll post my results to the list when I get some air-time with the new Cory
rod.

Hi Bob,
I haven't done a lot of specific comparisons, but my impression is that the
Cona rod, being less textured, is better served with a more consistent,
finer grind. Ironically, the coarse grinds in the most commonly used
grinders don't come out nearly as consistently as the fine grinds, and the
Cona rod needs most of all a consistent grind.
The Cona is also better at filtering out fines than the Cory and Conrning
rods, and so it stands up to finer grinding from that angle as well. You'll
generally have less sediment in the cup with the Cona than the Cory, so,
again, you can grind finer.
In general, though, the Cory rods seem to provide the best overall
performance in terms of the mechanics of drawdown. Because they tend to let
more fines through, you'll want to grind coarser to limit the amount of
fines that get through.
Do let us know how you get on. As always, we'll be looking for more vacpot
data points!
Doug

Doug,
My results with the vac pot have been spotty in the past.  I have noticed 
that I get better results with coffee ground in my Anfim than I did with my 
MDF.  Even drip is better with the Anfim.  I found I could grind finer and 
still not hit bitterness.  It will be interesting to do some Cory/Cona 
experiments.
I fear I'm getting VacPot-itis....
