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.

Specialty coffees are generally roasted in small batches. The
two most common roasting methods are: drum-roasting and hot-air
roasting.
Drum-type roasting
machines roast the coffee beans as they tumble in a rotating
drum that is typically heated by gas or wood.
When the desired
roast is achieved, the beans are poured into a cooling hopper
to keep them from overcooking.
The hot-air roaster,
also known as a fluid-bed roaster, roasts the coffee beans as
they tumble on a current of hot air.
Most green coffee
is roasted at approximately 400 degrees. The roasting process
causes the coffee beans to swell and increase in size by over
50%, while at the same time greatly reducing their weight.

A lightly roasted
bean may range in color from cinnamon to a light chocolate tan.
Lighter roasts are generally used for brewed coffee since they
produce a smoother, more acidic taste than do darker roasts.
Darker roasts,
in contrast, have a fuller flavor approaching a bittersweet
tang. The amount of oil drawn to the surface of the bean increases
proportionately to the length of roasting time.
As the roast darkens,
caffeine and acidity decrease proportionately. Dark roasts can
range in color from a medium chocolate brown with a satin-like
luster, to an almost black bean with an oily appearance. The
darker the roast the more you will taste the char, rather than
the flavor of the bean.
Extreme dark roasts
will tend to have a smoky flavor, and are better suited for
espresso.
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.
French roast is
the term sometimes used to describe the darkest roast. It is
important for you to understand that these terms have no relationship
to where the coffee is grown or roasted.
With more than
100 coffee-growing regions in the world, each producing beans
with distinctive characteristics, we believe proper blending
is essential to the balance of flavors necessary to create a
superior cup of coffee.
A single coffee
bean will generally not possess the complexity necessary for
a great brew. All of our blends contain three to seven different
types of beans. Even our 100% Colombian utilizes beans from
3 totally distinct growing areas of Colombia.
Our experienced
roaster, with his knowledge of each bean, artfully combines
them to create the desired blend of flavors. The roaster's blending
knowledge is a closely guarded secret.
In the United
States, 100% Arabica beans are generally used for gourmet blends,
although with some companies some robusta beans will be added
for the additional caffeine, complexity, and price advantage
they contribute to the blend.
Argument still
exists among roasters as to which should occur first, the roasting
or the blending. We believe roasting each varietal separately
to maximize its flavor characteristics, and then blending, will
produce the best result.
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, 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 package
helps 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. Roasts where oils
are exposed on the surface of the bean are much more vulnerable.
Once exposed to
the air, and if properly stored, beans will stay reasonable
fresh for 7 to 10 days. We recommend storing beans in a clean,
dry, air-tight container, in a cool dark place.
We do not recommend
storing beans in a refrigerator unless they are in a sealed
container, 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.
