There were several posts by various persons who pretended that they had in fact brewed the genuine klava, using the partial description of eggshells & wood chips described in "Issola". Would those persons who believe they have successfully re-created this drink be so kind as to post the actual materials, methods, quantities & times, as precisely & completely (& nicely & accurately) as possible so that others may try it (e.g., what kind of coffee did you start out with, what kind of wood, what species of bird for the eggshells (just in case anyone tried duck or goose), how were these materials combined, how long was A in contact with B, etc, etc)? For I confess, I am curious to know. And for those going to Brustian meets - perhaps a klava taste-off might be part of the activities?
