REAL COFFEE: PURCHASING, (HOME-)ROASTING, GRINDING, BREWING:  REAL COFFEE: PURCHASING, (HOME-)ROASTING, GRINDING, BREWING LIBRARIANS FORUM 13 DECEMBER 2006 EARLY COFFEE HISTORY:  EARLY COFFEE HISTORY Qahwah (“coffee”) is an Arabic word of uncertain etymology and is the origin of the usual words for coffee in various languages. It was originally a name for wine, attested already in ancient poetry. The word was transferred towards the end of the 8th/14th century in Yemen to the beverage made from the berry of the coffee tree. Another theory holds it a word of African origin and seeks to connect it with the alleged home of the coffee tree, Kaffa, in Ethiopia, although the word bun (Arabic al-bunn) for tree, berry and beverage is used there. The coffee tree was not indigenous to South Arabia and was probably introduced from the highlands of Ethiopia. The earliest known mention of coffee is found in Arabic writings of the 10th/16th century, in an essay by Ahmad Ibn `Abd al-Ghaffar, quoted by `Abd al-Qadir ibn Muhammad al-Jaziri , fl. 1568 in his `Umdat al-safwah fi hall al-qahwah. Legends hold that the consumption of coffee in Arabia first began among Yemeni Sufis. They were particularly fond of the beverage because its effect facilitated the performance of their religious ceremonies. COFFEE HISTORY:  COFFEE HISTORY In Mecca, according to the `Umdat al-safwah, the drinking of coffee in one form or other first appeared towards the end of the 9th/15th century. Drinking coffee established itself, and people drank coffee even in the mosque. Coffee-houses (buyut al-qahwah) were soon opened, where men and women met to listen to music or where they played chess or other games. This activity aroused the indignation of the ultra-pious, many of whom were always against the beverage as an objectionable innovation. It was often banned by religious authorities. But bans evaporated, and the consumption of coffee increased and spread. Coffee experienced similar sporadic bans in Cairo and elsewhere. Commerce among Mecca and Medina with Egypt brought coffee to Syria, Persia, and Turkey. Later bans came and went in various other cities: In religious circles, it was found that the coffee-house was bad for the mosque, and the `ulama' considered the coffee-house even worse than the wine-room. Preachers were especially eager for the prohibition of coffee and the way was paved for them by the muftis with an opinion that (roasted) coffee was to be considered as carbonized and therefore forbidden. The habit of coffee drinking spread to Europe and other parts of the world during the 17th and 18th centuries. (based in the article “kawha in the Encyclopaedia of Islam) O Coffee!:  O Coffee! Ya qahwatu tudhhibu hamma al-fita | O Coffee you dispel all care anta li-hawi al-ilm ni`ma al-murad | You are the object of desire to the scholar sharabu ahl Allahi fi-ha al-shifa | This is the drink of the friends of God. It gives health li-talibi al-hikmati bayna al-`ibad | To those among humanity who seek wisdom يا قهوة تذهب هم الفتا انت لحاوي العلم نعم المراد شراب اهل الله فيها الشفا لطالب الحكمة بين العباد `Abd al-Qadir ibn Muhammad al-Jaziri , fl. 1568, `Umdat al-safwah fi hall al-qahwah.

Its operation is simple and, despite coarse grounds, it produces a fuller flavor coffee than drip pots. REAL COFFEE:  REAL COFFEE What is real coffee? Not the canned or bagged stuff that comes from the grocery store; maybe not the bags of ground coffee or beans from specialty stores or coffee houses. All that stuff is very likely either stale when you buy it or will be before you consume it. Real Coffee is freshly (home-) roasted and ground just before brewing. NOT $TARBUCKS:  $TARBUCKS This show and tell will not bash $tarbucks : Starbucks sells and brews very good coffee, perhaps a bit over-roasted ("Charbucks"). There are several very good coffee houses in Ann Arbor and beyond (among them, Espresso Royale, Zou Zou's, Pierce's Pastries Plus, etc.) How to Brew Coffee:  How to Brew Coffee I will show you how to brew real coffee: home roasted in very small batches (<1/2 lb. per week?), ground in a burr grinder (not a blade grinder), and brewed in a drip pot (not a percolator!), French press, vacuum pot, Ibrik, or espresso machine (not a steam-toy). NOT For a modest investment, you can enjoy real coffee:  For a modest investment, you can enjoy real coffee BURR GRINDERS:  BURR GRINDERS Burr grinders ($100-$150), inexpensive to moderate (Rancilio Rocky, Baratza, Capresso, Solis Maestro (Plus) NOT a blade grinder—they cut the coffee beans into uneven chips and powder. Burr grinders crush into even grounds. COFFEE BEANS:  COFFEE BEANS Coffee beans, either green or very fresh roasted (mail order or locally available at Whole Foods) HOME ROASTING:  HOME ROASTING Coffee roasters $0-$450): Air Popcorn Popper, iron frying pan, Hearthware iRoast, Zach & Dani's (best deal), FreshRoast Plus, HotTop Drum Roaster, Gene Cafe Drum Roaster, Stovetop Popcorn Popper (Whirley Pop) ARABICA or ROBUSTA:  ARABICA or ROBUSTA Arabica beans are the best; Robusta are not so good but serve a purpose as they are blended in small quantities with Arabica to produce richer “crèma” in espresso. They are cheap and widely used in supermarket coffee to keep the cost down, and they have higher caffeine content. Arabica is distinctly milder and more aromatic. It possesses fewer sharp and bitter tastes than Robusta, and it is therefore considered the superior species by those who cultivate specialty coffees, single estates and varietals. CRÈMA!:  CRÈMA! Crèma, a reddish-brown foam which floats on the surface of well brewed espresso, is composed of vegetable oils, proteins and sugars. Crèma has elements of both emulsion and foam colloid. Some beans produce more copious amounts of crèma, e.g., Indian monsooned Malabar. CRÈMA!:  CRÈMA! ROASTING DEGREES:  ROASTING DEGREES From Green to Conflagration!
