Coffee

 

Coffee was first discovered in Eastern Africa in an area we know today as Ethiopia. A popular legend refers to a goat herder by the name of Kaldi, who observed his goats acting unusually frisky after eating berries from a bush. Curious about this phenomena, Kaldi tried eating the berries himself. He found that these berries gave him a renewed energy. The news of this energy laden fruit quickly spread throughout the region.

Monks hearing about this amazing fruit, dried the berries so that they could be transported to distant monasteries.They reconstituted these berries in water, ate the fruit, and drank the liquid to provide stimulation for a more awakened time for prayer.

Coffee berries were transported from Ethiopia to the Arabian peninsula, and were first cultivated in what today is the country of Yemen.

From there, coffee traveled to Turkey where coffee beans were roasted for the first time over open fires. The roasted beans were crushed, and then boiled in water, creating a crude version of the beverage we enjoy today.

Coffee first arrived on the European continent by means of Venetian trade merchants. Once in Europe this new beverage fell under harsh criticism from the Catholic church. Many felt the pope should ban coffee, calling it the drink of the devil. To their surprise, the pope, already a coffee drinker, blessed coffee declaring it a truly Christian beverage.

Coffee houses spread quickly across Europe becoming centers for intellectual exchange. Many great minds of Europe used this beverage, and forum, as a springboard to heightened thought and creativity.

In the 1700's, coffee found its way to the Americas by means of a French infantry captain who nurtured one small plant on its long journey across the Atlantic. This one plant, transplanted to the Caribbean Island of Martinique, became the predecessor of over 19 million trees on the island within 50 years. It was from this humble beginning that the coffee plant found its way to the rest of the tropical regions of South and Central America.

Coffee was declared the national drink of the then colonized United States by the Continental Congress, in protest of the excessive tax on tea levied by the British crown.

Espresso, a recent innovation in the way to prepare coffee, obtained its origin in 1822, with the innovation of the first crude espresso machine in France. The Italians perfected this wonderful machine and were the first to manufacture it. Espresso has become such an integral part of Italian life and culture, that there are presently over 200,000 espresso bars in Italy.

Today, coffee is a giant global industry employing more than 20 million people. This commodity ranks second only to petroleum in terms of dollars traded worldwide. With over 400 billion cups consumed every year, coffee is the world's most popular beverage. If you can imagine, in Brazil alone, over 5 million people are employed in the cultivation and harvesting of over 3 billion coffee plants.

Sales of premium specialty coffees in the United States have reached the multi billion dollar level, and are increasing significantly on an annual basis.

After quality coffee beans are obtained, the most important phase of the production of gourmet coffee begins, the roasting and the blending.

A good roaster must be part artist, and part scientist, to maintain quality and consistency. It is during the roasting process that the sugars and other carbohydrates within the bean become caramelized, creating a substance which is known as the coffee oil. Technically, this fragile chemical is not actually an oil (since it is water soluble), but it is what gives the coffee its flavor and aroma.

A lightly roasted bean may range in color from cinnamon to a light chocolate tan. Lighter roasts are generally not used for espresso since they produce a sharper, more acidic taste than do darker roasts. Darker roasts, in contrast, have a fuller flavor approaching a bittersweet tang. As the roast darkens, caffeine and acidity decrease proportionately. The darker the roast the more you will taste the char, rather than the flavor of the bean.

Many roasters refer to the following terms concerning the degree of roast, from light to dark: Cinnamon, Medium High, City, Full City, French, and finally, Espresso or Italian roast.

On the West coast of the U.S., French roast is the term generally used to describe the darkest roast. These terms have no relationship to where the coffee is grown or roasted.

A single coffee bean will generally not possess the complexity necessary for great espresso. Many espresso blends will contain three to seven different types of beans.

The experienced roaster, with his knowledge of each bean, artfully combines them to create the desired blend of flavors. The roaster's blending knowledge is usually a closely guarded secret. The Italians possess generations of expertise in the art of blending coffees for espresso.

Freshly roasted beans will release hundreds of chemical substances in the form of vapors. A day or two will generally be required for these gases to dissipate before the beans will reveal their optimal flavor characteristics.

Today, many quality roasters are packaging their beans in air tight bags with a one way valve, which allows the gases to escape, without the beans being exposed to the damaging air. This type of packaged should help retard flavor deterioration.

If beans are not packaged this way, or once beans packaged air tight are exposed to the air, they will begin to deteriorate. Once exposed to the air, and if properly stored, beans will stay reasonably fresh for 7 to 10 days. Store beans in a clean, dry, air-tight container, in a cool dark place. Storing beans in a refrigerator is not recommended because coffee tends to absorb flavors. Freezing coffee beans can also have a damaging effect, and is not recommended, unless the the beans must be stored for a prolonged period of time. Ideally, you should strive to purchase and use-up your supply of roasted beans on a weekly basis.

While tasting the coffee, you should try to discern whether the flavor, body, acidity and aroma of the coffee is pleasant, or unpleasant. Here are the criteria that most tasters use to judge coffee:

Acidity
Acidity is a desirable characteristic in coffee. It is the sensation of dryness that the coffee produces under the edges of your tongue and on the back of your palate. Without sufficient acidity, the coffee will tend to taste flat. Acidity should not be confused with sour, which is an unpleasant, negative flavor characteristic.

Aroma
Aroma is a sensation which is difficult to separate from flavor. The aroma contributes to the flavors we discern on our palates.

Body
Body is the feeling that the coffee has in your mouth. It is the viscosity, heaviness, thickness, or richness that is perceived on the tongue. A good example of body would be that of the feeling of whole milk in your mouth, as compared to water. Typically, Indonesian coffees will possess greater body than South and Central American coffees.

Flavor
Flavor is the overall perception of the coffee in your mouth. Acidity, aroma, and body are all components of flavor. It is the balance and homogenization of these senses that create your overall perception of flavor. The following are typical flavor characteristics:

General flavor characteristics:

Richness — refers to body and fullness
Complexity — the perception of multiple flavors
Balance — the satisfying presence of all the basic taste characteristics where no one over-powers another

Typical specific desirable flavor characteristics:

Bright, Dry, Sharp, or Snappy — (typical of Central American coffees)
Caramelly — candy like or syrupy
Chocolaty — an aftertaste similar to unsweetened chocolate or vanilla
Delicate — a subtle flavor perceived on the tip of the tongue (typical of washed New Guinea arabica)
Earthy — a soily characteristic (typical of Sumatran coffees)
Fragrant — an aromatic characteristic ranging from floral to spicy
Fruity — an aromatic characteristic reminiscent of berries or citrus
Mellow — a round, smooth taste, typically lacking acid
Nutty — an aftertaste similar to roasted nuts
Spicy — a flavor and aroma reminiscent of spices
Sweet — free of harshness
Wildness — a gamey flavor which is not usually considered favorable but is typical of Ethiopian coffees
Winy — an aftertaste reminiscent of well-matured wine (typical of Kenyan and Yemeni coffees)

Typical specific undesirable flavor characteristics:

Bitter — perceived on the back of the tongue, usually a result of over roasting
Bland — neutral in flavor
Carbony — burnt charcoaly overtones
Dead — see "flat"
Dirty — a mustiness reminiscent of eating dirt
Earthy — see "dirty"
Flat— lack of acidity, aroma, and aftertaste
Grassy — an aroma and flavor reminiscent of freshly cut lawn
Harsh — a caustic, clawing, raspy characteristic
Muddy — thick and dull
Musty — a slight stuffy or moldy smell (not always a negative characteristic when in aged coffees)
Rioy — a starchy texture similar to water which pasta has been cooked in.
Rough— a sensation on the tongue reminiscent of eating salt
Rubbery — an aroma and flavor reminiscent of burnt rubber (typically found only in dry-processed robustas)
Soft — see "bland"
Sour — tart flavors reminiscent of unripe fruit
Thin — lacking acidity, typically a result of under brewing
Turpeny — turpentine-like in flavor
Watery — a lack of body or viscosity in the mouth
Wild — gamey characteristics

Coffee Growing Regions

Latin America & The Caribbean
The coffees produced in this growing region are distinguished by their light body, simplicity and sharp acidity. They are typically thought of as having bright flavors with a clean, crisp finish. Colombia produces 12% of the world's coffee supply, and is second only to Brazil.

Africa & the Arabian Peninsula
Coffees from this growing region are the most distinctive in the world, characterized by dry, winy acidity, chocolate and fruit undertones, rustic flavors and intense aromas. Ethiopia is the native land of coffee, and it was in Yemen that coffee was first cultivated and prepared.

Indonesia is the world's third largest producer of coffee.

Tips

Buying Tip
When purchasing coffee, always ask when it was roasted. Many common misconceptions exist when it comes to judging the freshness and optimum time to experience a roasted coffee at its peak of perfection. Generally coffee is best if used a day or two after roasting, and if kept in an air-tight container, flavor should not diminish significantly until after seven to ten days. Old coffee beans may appear very oily, will have little or no aroma, or will take on a somewhat unpleasant aroma.

Grinding Tip
Never grind more coffee than you will use for immediate brewing. Once the beans are ground, the flavorful oils are exposed to the damaging air. As these oils dissipate, so will the flavor of your coffee. Once ground, coffee will begin to lose its flavor almost immediately. Different methods of brewing will require different grind consistencies. Typically, coffee used for drip brewing should be ground to a consistency similar to granulated sugar. The complete drip cycle should occur within four to six minutes. If the drip cycle is completed in less than four minutes, grind your coffee finer. If the cycle takes longer than six minutes, grind your coffee coarser. When using a French press, the coffee will need to be ground extremely coarse. Espresso requires an extremely fine grind...almost powder-like with a slight grittiness.

Storage Tip
Never store your coffee in the refrigerator. Coffee will absorb flavors and aromas from other food products in your refrigerator. Freezing coffee can also have a damaging effect, and it is not recommended unless you will not use-up your supply of coffee for a prolonged period of time (two weeks or more). Coffee should be stored in a clean, dry, airtight container, in a cool, dark place.

Dosage Tip
When making brewed coffee, allow 2 to 2 1/2 level tablespoons for each 6 ounces of water (3 tablespoons for 8 ounces). For espresso, allow 7 to 8 grams for a single shot, and 14 to 16 grams for a double shot.

Filter Drip Tip
Be sure to use a filter which is designed to fit your filter basket. Bleached white paper filters are most common, however unbleached brown filter papers are usually available. Permanent gold-plated wire mesh filters also work very well and are environmentally friendly.

French Press Tip
You will want to grind or have your coffee ground to a very coarse consistency for this method. If your grind is too fine, you will over extract your coffee and a bitter flavor may result. It will also be difficult or impossible for you to push the plunger down in your pot if the grind is too fine. Now here is an application for your French press that you probably don't know about. Heat a cup of milk (non-fat works best) in a sauce pan on your stove or in a microwave. It should be heated just until it is too hot to put your finger in it. Don't overheat or you will scald the milk. Next, pour the milk into your clean, empty French press. Insert the plunger, and pump the plunger up and down like a butter churn for several minutes. The milk will expand and increase in volume by three or four times, creating beautiful frothed milk for cappuccinos and lattes.

Why foam milk? Because everyone else is doing it? No, milk is foamed and steamed for one reason and one reason alone, to enhance and elevate the sensory experience of coffee, and espresso in particular.

Properly prepared milk is always foamed. Even if you don’t want any foam in the drink you want to foam the milk just slightly. Incorporating air into the milk improves and sweetens the taste. Milk that has not been foamed at all tends to taste flat and dull by comparison.

You will have incorporated foam into the milk but it will not be sitting on the top with the steamed milk underneath. Oh no, it will be intertwined and mingled all through the entire pitcher of milk. Ideally when you pour the milk into the cup that is where you will see a settling out of the foam on top. The quantity of foam you have incorporated into the milk will be dependent on how much is required for the drink and how aggressively you worked to incorporate air into the milk.

Coffee and Health Issues
Coffee has been studied for more than a century. For every report that alleges a potential health risk, another may discredit or show benefits. It is generally agreed that pregnant women should limited their coffee consumption. Did you know that drinking a cup of coffee can help calm an acute attack of asthma? Coffee has many positive effects.

Espresso at Home
When selecting a machine for home, look for one that will drive the water through the coffee with the aid of a pump vs. a steam driven machine. A good pump machine will usually cost $200 to $1,000, but the investment is worth it if you are serious about enjoying tasty espresso.

Mexican Melange Latte
Pour 1/4 ounce each of almond, coconut, banana, and cinnamon syrups into a cup. Add espresso, and fill with steamed milk. Top with shaved chocolate.

Café au Lait
It is a big milky cup of coffee that is is made with double strong drip coffee, not espresso like its cousin the latte.

Warning to you girly-men out there: this’ll be a solid cup of coffee that’ll put hair on your legs and believe it or not that’s exactly what you want. Also to stay true to tradition use a dark roast coffee, ideally a French Roast or something with a smoky bite. Combine this with hot milk in a ratio of 50:50 and poured into a nice big bowl that you’ll need two hands to grip. Pour the coffee and the milk into the bowl at the same time for extra style points and the best mixing of the two liquids.

You can steam or heat the milk in a couple of ways. There's the stove of course, but you must remember to always keep the milk moving. No one likes a thick skin of milk crust on his or her café au lait.

One step better is to use an auto, or regular manual frother that will not only allow you to heat the milk but to foam it as well. Although foam is not a feature of the café au lait normally, a little foam never hurts.

Caffe Latte
Although very similar to the café au lait the latte uses espresso as the "coffee" base for a slight twist on the experience.

Cappuccino
The ideal cappuccino is one third each of espresso, steamed milk, and frothy foam.

What is the history of Cappuccino? Although nobody knows for sure, common belief is that it is named for the robes and cowl of the Capuchin monks habit. Whether the Capuchin monks were the originators of this exquisite hot beverage is unknown and tradition tells us that a properly prepared cappuccino of espresso and steamed milk leaves a brown ring along the rim of the cup much like the edge of the monks cowl.
