Many thanks to all who replied to my request for information. To Tom and 
Maria..... I did mean coffee grown in Cuba, as opposed to method of 
preparation - apologies for not making this clear. To Tom 
Ulmer.....Proctor and Gamble, eh !! Now why am I not surprised ??
I agree that it is very much a part of the coffee home- roaster's nature 
to try all that is available, then separate 'wheat from chaff'.....Kopi 
Luwak, for instance, retails in England for £32($50) for 250 grams ! 
That's roughly $100 a pound for Civet-crap robusta ! I'm guessing that  
the Indonesian poop-sifters don't  see much of  those profits.Thanks 
again to all concerned, Michael
