The History Of Coffee

Coffee - THE Drink of Choice

Did you know coffee is the most consumed beverage on the planet.

The Beginning of Coffee

Along with these people, other Africans of the same period also have a history of using the coffee berry pulp for more than one occasion like rituals and even for health. It looks as if the first trace came out of Abyssinia and was also sporadically in the vicinity of the Red Sea around seven hundred AD.

It became so popular among the Arabs that they made it their signature Arabian wine and it was used a lot during rituals. Roasting and boiling the bean was how they made this drink. The Arabs started making a drink that became quite popular called gahwa--- meaning to prevent sleep. It is speculated that trade ships brought the coffee their way. Coffee began to get more attention when the Arabs began cultivating it in their peninsulas around eleven hundred AD.

After the coffee bean was found to be a great wine and a medicine, someone discovered in Arabia that you could also make a different dark, delicious drink out of the beans, this happened somewhere around twelve hundred AD. After that it didn't take long and everyone in Arabia was drinking coffee. Everywhere these people traveled the coffee went with them. It made its way around to India, North Africa, the eastern Mediterranean, and was then cultivated to a great extent in Yemen around fourteen hundred AD.

Other countries would have gladly welcomed these beans if only the Arabs had let them. The Arabs killed the seed-germ making sure no one else could grow the coffee if taken elsewhere. Heavily guarding their plants, Yemen is where the main source of coffee stayed for several hundred years. Even with their efforts, the beans were eventually smuggled out by pilgrims and travelers.

Coffee Shops Appear

Around 1475 the first coffee shop opens in Constantinople called Kiv Han two years after coffee was introduced to Turkey, in 1554 two coffee houses open there. People came pouring in to socialize, listen to music, play games and of course drink coffee. Some often called these places in Turkey the "school of the wise", because you could learn so much by just visiting the coffee house and listening to conversations. In the sixteen hundreds coffee enters Europe through the port of Venice. The Turkish warriors also brought the drink to Balkans, Spain, and North Africa. Not too much later the first coffee house opens in Italy.

There were plenty of people also trying to ban coffee. Such as Khair Beg a governor of Mecca who was executed and Grand Vizir of the Ottoman Empire who successfully closed down many coffee houses in Turkey. Thankfully not everyone thought this way.

Coffee Tips Arrive

In the early sixteen hundreds coffee is presented to the New World by man named John Smith. Later in that century, the first coffee house opens in England. Coffee houses or "penny universities" charged a penny for admission and for a cup of coffee. The word "TIPS" (for service) has it's origin from an English coffee house.

Early in the 17th century, Edward Lloyd's coffee house opens in England. The Dutch became the first to commercially transport coffee. The first Parisian café opens in 1713 and King Louis XIV is presented with a lovely coffee tree. Sugar is first used as an addition to coffee in his court.

The America's Have Coffee

Coffee plants were introduced in the Americas for development. By close to the end of the seventeen hundreds, 1,920 million plants are grown on the island.

Evidently the eighteen hundreds were spent trying to find better methods to make coffee.

The Coffee "Brew" in the 20th Century

New methods to help brewing coffee start popping up everywhere. The first commercial espresso machine is developed in Italy. Melitta Bentz makes a filter using blotting paper. Dr. Ernest Lily manufactures the first automatic espresso machine. The Nestle Company invents Nescafe instant coffee. Achilles Gaggia perfects the espresso machine. Hills Bros. begins packing roasted coffee in vacuum tins eventually ending local roasting shops and coffee mills. A Japanese-American chemist named Satori Kato from Chicago invents the first soluble "instant" coffee.

German coffee importer Ludwig Roselius turns some ruined coffee beans over to researchers, who perfected the process of removing caffeine from the beans without destroying the flavor. He sells it under the name Sanka. Sanka is introduced in the United States in 1923.

George Constant Washington an English chemist living in Guatemala, is interested in a powdery condensation forming on the spout of his silver coffee flask. After checking into it, he creates the first mass-produced instant coffee which is his brand name called Red E Coffee.

Prohibition goes into effect in United States. Coffee sales suddenly increase. Brazil asked Nestle to help find a solution to their coffee surpluses so the Nestle Company comes up with freeze-dried coffee. Nestle also made Nescafe and introduced it to Switzerland.

Other Interesting Coffee Tidbits

Today the US imports 70 percent of the world's coffee crop. During W.W.II, American soldiers were issued instant Maxwell House coffee in their ration kits.

In Italy, Achilles Gaggia perfects his espresso machine. The name Cappuccino comes from the resemblance of its color to the robes of the monks of the Capuchin order.

One week before Woodstock, the Manson family murders coffee heiress Abigail Folger as she visits with her friend Sharon Tate in the home of filmmaker Roman Polanski.

Starbuck's Hits the Coffee World

Starbucks opens its first store in Seattle's Pike Place public market in 1971. This creates madness over fresh-roasted whole bean coffee. Coffee finally becomes the world's most popular beverage. More than 450 billion cups are sold each year by 1995.

The Current Coffee Trends

Drink and enjoy! Researchers are even finding many health benefits to drinking coffee. There's no sign of coffee consumption decreasing. We have really come a long way even with our coffee making machines. Now in the 21st century we have many different styles, grinds, and flavors of coffee.

Coffee: From Harvest to Cup

Coffee is a plant. However, before it can be drunk it must pass through a number of stages and travel thousands of miles.

Coffee beans come from the red cherries of the coffea bush. Each cherry usually contains two seeds, or coffee beans. The exception to this is the Peaberry, where only one bean is produced. The flavour a bean produces is affected by where the coffea bush is grown. Soil, climate and altitude all alter the way coffee tastes; this is why, for example, coffee from Columbia will differ in taste from region to region and from year to year.

Most coffee comes from two species of the coffea bush: Coffea arabica, simply known as ‘arabica'; and Coffea canephora var. robusta, simply known as ‘robusta'. Robusta beans are cheaper to buy then arabica beans because they produce coffee with an inferior flavour, containing more caffeine.

When the red cherries have been harvested from the coffea bush, the outer layers of pulp and skin must be removed to reveal the green coffee beans inside. There are two common methods of doing this: the ‘natural' or dry method, and the ‘washed' or wet method. The natural process of removal tends to give coffee a full-bodied yet mild aroma, whereas the washed process yields strongly aromatic coffee, with a fine body and a lively acidity.

In the washed method the outer pulp is removed using a mechanical pulping machine before the cherry is immersed into a fermentation tank for between 12 to 32 hours, after which the remaining pulp and skin is washed off, revealing the green bean. Finally, the bean is left out in a sunny area for between 12 to 15 days to dry.

In the natural method, the cherry is simply left to dry out in the sun for up to four weeks. During this time the pulp and skin become shrivelled and can then be easily removed.

The coffee beans are then sorted and graded by size and density. Generally the larger the coffee beans the better the coffee. The largest bean is known as ‘Maragogype' or Elephant bean. There is no international grading system for coffee beans, with different countries using alternative systems. For example, in many African countries, the highest grade of coffee is AA, whereas, in Indonesia it is Grade 1.

Green coffee beans must first be roasted before they can be used to make a cup of coffee. The roasting process produces the primary flavour and aroma of coffee. Beans are roasted by a skilled coffee roaster, who judges how long to roast the beans in order to produce the optimum taste. For example, Javanese coffee is usually roasted for a lengthy time to give it a full-bodied and earthy flavour. However, if heat is applied to the beans for too long, it will destroy this flavour and give it a burnt aroma.

The final process before you can enjoy your cup of coffee is grinding. The coffee beans need to be ground ready to infuse, using your preferred brewing method. Different brewing methods require a different coarseness of coffee in order to produce the best possible taste. For example, using a cafetiere you need coarse coffee grounds, whereas when using a stove-top espresso maker you require a much finer grind.

coffee bean processing and roasting 101

This pit, containing up to 2.5 percent caffeine, is a major export for several countries. Technically speaking the bean is the pit, similar to the pit found in a cherry or apricot, but with two half oval shapes facing each other. The coffee plant produces a red or purple fruit, but people are less interested in that than they are in the actual coffee bean. Unripe and bad beans will float to the top, while the good beans will sink to he bottom. The green bean is then put through a process of sorting, done by immersing the bean in water. The coffee bean is cultivated and is green. This is how most coffee is processed. The beans are then thoroughly rinsed with water to get rid of the microbes. Pulp that is left on the beans is removed by letting them sit in a pool full of microbes for several days. Once the sorting has been done, the beans are washed and fermented. The oldest and most traditional ways of processing coffee is the dry method. The beans, once harvested, are laid out in thin layers on tables to dry out in the sun. This takes significantly longer to do, up to two weeks. To prevent mildew, the beans need to be moved around a lot. This dry processed coffee is in high demand, but because it is so much more labor intensive, only a few regions do it. Ethiopia produces the most, followed by Brazil and Yemen. Once processed, green coffee beans can be stored for up to a year. If kept in a cool, clean and dry place, there is no reason for it to go bad before the year is up. Almost all of the coffee that consumers across the world buy has already been roasted, though it is possible to buy green coffee and roast it themselves at home. The coffee bean is then roasted.
