We use the two-serving size briki's made of copper - you can buy them from Cost Plus. I have one at home too, but use a small metal one (aluminum?) for one serving myself at home. I forget the brand of coffee we buy, but it is GREEK style - NOT Turkish. We just grab water from I think a large coffee maker (to keep it warm)...or from a 5 gal water bottle. We cook it over a flame on a propane tank powered stove (two burners). We have been charging $1 for years (just had our 20th year last year) and usually sell about 6 1 lb bags worth (however many cups that makes). It comes out to about a 4oz serving in those small styrofoam cups.
Greek style coffee has chicory in it, is a lighter roast and I'm told by our old Macedonian, that ground garbanzos actually are added to help lighten it. Turkish styles have a darker roast and cardamom is usually added to the blend, which can make it taste almost medicine-like in my opinion if you're not used to it. I've tried Egyptian and an "African" style (half chocolate, no sugar and double amounts of grounds due to the chocolate) and berber blends (coriander) as well. I remember reading somewhere that Greek grounds are actually finer than Turkish historically, as the Greeks, being subject to the Turks, would get the leftover grounds ("dust") from the mill to make their coffee. I don't have any backup to this though.
I think it is too cheap and think we should raise it to $2 (as the booth head, I have already decreed it - I just want confirmation of the appropriateness). Our parish is OCA, been around over 70 years, but very international in nature. Our booths are usually: outside bakery (togo), crafts, Russian (piroshki & borscht), greek style sliced lamb and rice (w/ greek salad and or bread), spanikopita and tiropita, gyros, Eritrean, Kebabs, Mediterrean (falafels - usually tabouleh, but I guess they say it is too much work this year), Serbian (green beans, sarma and potato salad), coffee (my booth), ice cream & soda, wine and beer (two different booths). Lotsa other stuff to do, but just listing the food booths.
For you other experienced festival veterans, let me know what you think price-wise.
