Characteristics Guide
Green coffee beans are high in chlorogenic acid, an unpleasant
harsh acid. The roasting process is critical in developing
a beans ultimate characteristic. During the process, temperature,
length of roasting, and air flow all contribute to maximizing
the beans ultimate characteristics. Hundreds of chemical substances
in the form of vapors are released as well the breaking down
of the acids. The roasting process causes the coffee bean
to swell increasing their size by over 50%, while at the same
time reducing their weight. The amount of oil drawn to the
surface of the beans also increases proportionately to the
length of the roasting time. As the roast darkens, caffeine
and acidity decrease. The acidity is directly related to sugars
that form during the roasting. The combination of acidity
and sugars impact the overall "body" of coffee. Thus, lightly
roasted beans tend to be more acidic than a darker roast,
the darker roast also yielding a richer, deeper, more robust
flavor. Once roasted, the beans continue to dissipate gases
for a day or two before reaching their optimal flavor.
Certain characteristics are easy to distinguish, even for
the beginning taster. Noted below are the various key characteristics.
Aroma The smell or bouquet of the coffee or the strength
of the vapors released from freshly brewed coffee. Because
the sense of taste and the sense of smell are so closely related,
the presence of a powerful, evocative aroma can really enhance
the experience of a great coffee. Many exceptional coffees
do not have a notable aromatic quality (Aroma 1), while others,
when brewed; pervade a room with the desire to drink coffee
(Aroma 4). Aroma is more important to those who rely on a
sense of smell to enhance taste.
Body is the sense of fullness, richness or thickness
perceived on the tongue when one tastes coffee - the impression
of lightness or weight when drinking coffee. . A comparison
would be the difference between a light white bread and a
moist whole grain loaf. The heavier the feel, the thicker
the brew. The perception of the body of the coffee is related
to the oils and solids extracted during brewing. Coffees with
a heavier body will maintain more of their flavor when diluted.
Flavor Flavor is the overall perception of the coffee
in your mouth. Acidity, Aroma and Body are all components of
Flavor. General characteristics are Richness - refers to body
and fullness, Complexity - the perception of multiple flavors,
and Balance - the satisfying presence of all the basic taste
characteristics where no one overpowers another. Ranges from
mild, to deeply rich and complex.
Acidity is often assessed as lively or snappy (Acidity
4), moderate, flat or mild, or dull or light (Acidity 1).
Acidity is best described as a pleasant, tangy "bite" at the
first taste, a sharp "nippy" taste or snap denoting a pleasant
tartness, and is considered a desirable quality by many coffee
lovers.
Coffee Beans While there are
over twenty species of coffee plants, two account for the
majority of commercial coffee sold worldwide:Arabica and Robusta.
Arabica coffee beans offer the finest aroma, flavor and
body. They are grown in nutrient-rich soil along the equator
at elevations between 3,000 and 6,000 feet where the cooler
climate and soil conditions provide an environment in which
the plant more slowly matures and help it to develop a more
richly flavored characteristic. Altitude offers a good clue
to flavor and acidity, as a general rule, the higher the altitude,
the more delicate the flavor and crisper the acidity.
Significantly less expensive to grow, more disease and pest
resistant, Robusta plants have twice the caffeine content
of Arabica beans. Growing anywhere from sea level to 3,000 feet
the Robusta plant produces far more beans in a shorter amount
of time than Arabica plants. Coffee aficianados considered the
Robusta bean "inferior" to Arabica beans lacking the
flavor intensity of Arabica beans.Robusta beans are mostly used
in supermarket blends and instant coffees.
Roasting Styles Currently used
names for roast styles come from two sources, one the general
roasting preferences of various nations - Italian, French,
etc. The other developed within the American coffee profession
during the late 19th and early 20th centuries.
Geographical Roast Names The common roast names representative
of coffee-drinking geography. These are the names you are
most likely to see on coffee bags and bins.
- New England (light brown, dry surface)
- American (medium brown, dry surface)
- Viennese (medium dark brown, possibly flecks of oil on surface)
- French (moderately dark brown, light oil on surface)
- Espresso (dark brown, surface can range from very oily to
barely slick depending on roast procedure) Italian (dark,
blackish brown, definite oily surface; most roasting establishments
stop here)
- Dark French or Spanish (very dark brown, almost black, very
oily).
Traditional American Roast Names Noted below traditional
American roasting terminology you may see on the shelves of
retailers.
- Cinnamon (very light) · Light (light end of the American norm)
- Medium
- Medium-high (American norm)
- City; high (slightly darker than norm)
- Full city (definitely darker than norm; sometimes patches
of oil on surface)
- Dark (dark brown, shiny surface; equivalent to espresso or
- French)
- Heavy (very dark brown, shiny surface; equivalent to Italian)
Roast Descriptions:
The most lightly roasted coffee (usually called cinnamon;
is very light brown in color, will display a strong, sometimes
sour acidity, little aroma, an often grainy taste, and thin
body. The surface will be dry.
As the coffee achieves a more complete but still relatively
light roast (New England, light); the acidify notes will
be powerful, and the varietal characteristics, which often
are nuances of acidity, will be pronounced. The body will
be developed, but not as fully as it will become in a somewhat
darker roast. The surface of the bean remains dry, as the
flavor oils continue to develop in tiny pockets inside the
bean
At a moderately light to medium-brown roast (light, medium,
American; the acidity will be bright but less overpowering,
the varietal characteristics still pronounced, and body fuller.
For most traditional East-Coast American coffee-drinkers this
style represents a "good" coffee taste
At a slightly darker, medium-brown roast (medium, medium
high, American, city; acidity remains strong though perhaps
richer, varietal characteristics muted but still clear, and
body still fuller. This is the traditional roasting norm for
most of the American west.
At a full city, often labeled Viennese roast;
acidity is slightly more muted and body slightly heavier.
The surface of the bean may remain dry, or oils may appear
in tiny droplets or patches as they begin to rise from pockets
inside the bean to its surface
At a moderately darker roast (espresso, European, high);
the acidity is largely folded into a general impression of
richness, the varietal characteristics muted virtually beyond
recognition, the body full, and the bittersweet notes characteristic
of dark-roasted coffees rich and resonant. At this roast the
surface of the bean always displays some oil, ranging from
a few droplets to a shiny coating.
When coffee is brought to a definitely dark roast (French,
Italian, dark); the bittersweet or dark roast taste completely
dominates, the body begins to thin again, and all remaining
varietal character and acidity notes are transmuted inside
the pungent richness of the dark roast flavor, which may range
from rounded and mellow (in less acidify coffees) to bordering
on bitter (in coffees that begin very acidity). The surface
of the bean will be bright with oil.
With very dark brown roasts (Italian, Dark French,
Spanish, heavy); the body continues to thin as more and
more of the oils are evaporated by the roast, the bitterest
side of the bittersweet equation becomes more dominant, and
a slight charred taste may appear. The bean is shiny with
flavor oils driven to the surface.
The ultimate dark roast, almost black (Dark French, Spanish);
is definitely a special taste. The body is even thinner, more
bitter and less sweet, and burned or charred notes dominate.
All coffees regardless of origin tend to taste about the same.
The surface of the bean is bright with oil. Home roasters
typically have an opportunity to sample this ultimate dark
roast, since sooner or later we all produce a batch whether
we plan to or not.
Estate Coffees
Many owners of quality-conscious coffee, and in some cases,
cooperatives of smaller growers, establish estate identities
for their coffees. Estates sell their coffees directly to
dealers without mixing them with other coffees from the same
region, in theory insuring that these coffees reflect consistent
growing conditions and processing practices.
Estate coffees have some advantages. Number one: The estate
concept helps identify coffees in precise terms. If you buy
the same coffee a second time it most likely will display
the same characteristics that attracted you to it in the first
place. A second advantage to buying by estate is that you
can select coffees according to specific growing practices,
social practices, or processing techniques. A third advantage
to estate coffees is that many offer superior or distinctive
versions of regional taste characteristics.
But, there are some disadvantages to buying coffee by estate
or cooperative? You may be limiting yourself from tasting
outstanding coffees that simply are not marketed by estate.
Second, estate coffees may be very good, but they may not
be warrant the considerably higher price often asked for them.
Finally, many of the estate and designated cooperative coffees
tend to work through a few selected wholesale roasters or
dealers and so their availability is often limited.
A Brief History Of Coffee
Coffee was first discovered in Eastern Africa around 850 AD
in an area of, Kaffa, (hence coffee) Ethiopia. Goat herders
noticed that some of the animals were more active after eating
the red berries of an indigenous shrub. Curious about this
phenomenon, they tasted them for themselves they found that
those who ate the berries said they felt happy and awake.
Gradually the people of the region began to eat them, initially
as berries, and then as grains dried by the sun. Coffee drinking
was an important social and cultural tradition in Ethiopia
and The coffee drinking ceremonies are important events providing
an opportunity for the men to discuss issues of social significance
and women to have time to talk to each other while doing their
traditional weaving, spinning and embroidery work
Note: The Coffee plant, sometimes referred to as a tree,
grows 8 to 10 feet high, has shiny green leaves and develops
a white flower that that has a very enjoyable aroma similar
to jasmine.The average tree is five years old before producing
its first crop and yields only 1 1/2 pounds of grains a year.
Once dried and roasted this equates to a pound of roasted
coffee.
In the fourteenth century, Monks hearing about this amazing
fruit dried the berries so that they could be transported
to distant monasteries where the berries were eaten and the
dried grains mixed in liquid to provide stimulation for a
more awakened time for prayer. The Coffee berries found their
way from Ethiopia to the Arabian Peninsula, and were first
cultivated in what today is the country of Yemen. The Arabs
calling the liquid "qhaweh" or "qahwa"
as translated - "the wine of Arabia."
In Turkey, the 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 in the 1600's
by means of Venetian trade merchants. The new beverage received
harsh criticism from wine merchants who saw it as a threat
to their market and asked the Pope to ban it calling it the
"Drink of the Devil." To their surprise, the Pope
like it, and 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.
The Dutch introduced coffee to Indonesia. Legend has it that
the original coffee plant, which was introduced into Java,
in 1696, was one of the seven highjacked coffee plants from
Arabia. Java became a major coffee producing area. However,
both the port of Mocha in Yemen and the island of Java in
Indonesia could not ship enough coffee to supply the growing
coffee demand in Europe. It should be noted that these two
ports' names are how coffee got the name Java and Mocha.
It is said, King Louis XIV called in a favor from a Dutch
trader and wanted him to supply him with a plant. This Dutch
trader obtained a plant form either Mocha or Java; beings
how both were on his itinerary and brought it back to Holland.
From Holland the single coffee plant went to Paris.
In the 1700's, coffee found its way to the Americas by means
of a French infantry captain, Chevalier Gabriel Mathiew de
Clieu 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 18 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 Haiti, and most of the islands
of the Caribbean, Mexico and Central America.
Finally, to round out our set of coffee notables, is the Don
Juan of coffee propagation, Francisco de Mello Palheta of
Brazil. The emperor of Brazil was interested in cutting his
country into the coffee market, and in about 1727 sent de
Mello Palheta to French Guiana to obtain seeds.
Like the Arabians, and the Dutch, the French didn't want their
coffee plants cultivated by other countries either. Legend
has it Don Francisco had a hard time getting at those seeds.
Fortunately for coffee drinkers, Don Francisco so successfully
charmed the French governor's wife that she sent him, buried
in a bouquet of flowers, all the seeds and shoots he needed
to initiate the billion-dollar coffee industry of Brazil.
The noble tree also sent shoots to the island of Reunion,
in the Indian Ocean, then called the Isle of Bourbon. This
plant was found to be a somewhat different variety of Arabica,
with smaller beans, and was named var.Bourbon. The famed Santos
coffees of Brazil the Oaxaca coffees of Mexico are said to
be offspring of the Bourbon tree. For the final irony, we
have to wait until 1893, when coffee seed from Brazil was
introduced into Kenya and what is now Tanzania, only a few
hundred miles south of its original home in Ethiopia, thus
completing a six-century circumnavigation of the globe.
Robusta coffee grows indigenously in Uganda and the Congo.
The second coming of Robusta coffee took place around the
1902 when Africa, just being explored by the Europeans, found
Robusta coffee,. The seeds were exported right away. Robusta
coffee plants found there way to Madagascar, West Africa,
Angola, West Indies, and Vietnam. This was because even as
late as the 1900's, having fertile coffee beans for export
is a crime in most coffee growing countries. Since central
Africa was not well controlled, explorers took what they wanted
and the spread of Robusta coffee began on a relatively large
scale.
Although the Dutch introduced coffee in America during the
1660's, tea was still the beverage of choice among the American
colonist. The boycott of tea due to taxes imposed by the King
of England led to the Boston Tea Party in 1773. This important
fight for freedom established coffee as the traditional democratic
drink of Americans.
Coffee has quickly become the beverage of choice around the
world. In the United States alone, an estimated 45 million
cups are brewed every day.
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. Today,
Espresso has become such an integral part of Italian life
and culture.
Today coffee industry is a giant global business 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.
