We're throwing a rehearsal dinner for my son's wedding party and assorted out of town guests next Thursday evening and I've volunteered to supply the coffee (actually, it's been long assumed that I will). Unfortunately, it looks like we'll be using a 50 cup percolator (eek!), something with which I have absolutely zero experience. I'm going to be using a home roasted Kenya but have no idea how much to use. Also, I traditionally roast my Kenya to Full City+. Would this be appropriate or does a percolator (eek!) suggest a different roast? Keep in mind that this event is not likely to be attended by any finely-honed coffee palates. My wife and I, on the other hand, would like to enjoy it.
Any ideas and/or experiences you could relate would be a big help.
Thanks, Mike
