Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
Ethiopian coffee is superb, it is simply coffee the way God created it. Biologically speaking, coffee originated in Ethiopia where it is indigenous. All the other places that grow great coffee, places like Colombia, Brazil, Guatemala, Jamaica, all these places merely duplicate the climate, elevation, and soil types of Kaffa Ethiopia where coffee both originates and gets its name. In fact, upwards of half the coffee produced in Ethiopia is still WILD! For these reasons Ethiopian coffee is the most flavorful, aromatic, and satisfying. In regards to it being "strong" that is just about who brewed your cup. Ethiopians themselves make it rather strong if you have a small cup of coffee in "the coffee ceremony" (ye buna afelal) but if you buy a bag of Sidamo or Yergecheffe beans at the grocery store, it actually has less caffeine then an Italian roast but tastes much stronger, more floral. Caffeine content in brewed coffee is largely determined by the roasting process.
Does this mean that Christians (specifically, Oriental Orthodox Christians) invented coffee?
According to tradition, an Ethiopian goat herder named Kaldi from the province of Kafa was the first man to discover coffee. Born around the year 650, he lived during the waning years of the Christian Aksumite Empire. A husband, father of two daughters, and foster parent to an orphaned nephew, Kaldi one day noticed his flock of goats dancing energetically. He determined the cause of their peculiar behavior to be the red coffee drupes they nibbled off nearby bushes. He took some of the fruit home, and he and his family began experimenting with them for culinary use.
When his nephew, Giorgis, entered the local Orthodox monastery, he shared his family's coffee roasting recipe. The monks enjoyed the drink and soon made a habit of offering it to brothers visiting from other monasteries across Ethiopia. Eventually, word of the delightful drink reached the monasteries of the Byzantine Empire and, in time, the rest of the world.
In an effort both to defend the farmers' welfare and strengthen Ethiopia's agriculture industry as a whole, former World Bank economist Dr. Eleni Gabre-Madhin in 2008 established the country's first commodities market: the Ethiopian Commodity Exchange (ECX).
Though much remains to be done to protect small farmers and expand Ethiopia's agriculture, the ECX has already made major headway in its first few years. It now requires, for instance, traders make more accessible to small farmers information about the market, which in the past they kept to themselves.
Yes, but how did coffee become a world drink is related to the Latins. Just as with chocolate from the New World, it was papal decrees which led to the popularity of coffee, which initially was only drunken in the Muslim world (including in Ethiopia, the Christians didn't develop a taste for it initially). When the popes approved coffee as an acceptable drink for Lent and fasting days, just like chocolate, it exploded as a viable Fasting treat. Lent has this affect on the world economy. Coffee and chocolate are two of the most widely consumed commodities, I think only rice is consumed more than coffee worldwide, and both became popular in their relation to Lent and fasting culture.
