Central to the debate was whether drinking coffee fell under the same prohibition against intoxication as wine. Quahweh, coffee, was also a poetical word for wine.

Through all of the time the coffee growers kept a complete control on the coffee plants and viable seeds. Foreigners were not allowed access to the Red Sea highlands plantations, and no viable seeds were allowed to leave the country. But around 1600 an indian pilgrim was able to smuggle seven beans back to Mysore by strapping them on his belly.

In 1690 a group of Dutch mariners managed to steal several live coffee plants and smuggle them out of the port of Mocha. they planted some of the saplings i java, a Dutch colony already supplying Europe with pepper, nutmeg, and other spices. At least one coffee plant was sent to the botanical garden in Amsterdam. A shoot of this plant was presented as a gift to king Louis XIV of France in 1713.

Ten years an enterprising Fresh officer, Gabriel-Mathieu de Clieu, the Captain of infantry in Martinique, broke into the Jardin Royale and stole the plant. De Clieu immediately set sail with his plant for the west Indies. In Martinique, de Clieu planted his treasure and protected it with guards and thorn bushes. the plant survived, and most of the coffee trees alive in the Western Hemisphere today are its descendants.

Brazil’s immense coffee industry got its start from one of the de Clieu’s trees that has been transplanted in Guiana. The Brazilians obtained the tree when France and Holland were having a dispute over the border between their colonies in Guiana, Brazil, in an act of friendship, sent an off icial envoy tp help mediate the conflict. During the deliberations, Lieutenant Colonel Francisco de melo Palheta stayed in Guiana with the French Governor and his wife. When he left, the governor’s wife, as an appreciative token of parting, gave him a bouquet of flowers. Hidden within the bouguet was a live cutting from a coffee tree.
