[Homeroast] Cory Rod in a Yama Vacpot?

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....

Bob
