Many
people are surprised when touring a coffee plantation because coffee
beans aren’t brown and don’t smell like “coffee.”
Ripe coffee beans are a beautiful, reddish color and are actually sweet
smelling and tasting. The best coffee beans are picked when they’re
a deep reddish color. In Colombia, only the ripe beans are picked –
handpicked – making Colombian coffee one of the most solicited
in the world. In many other coffee producing regions, the beans are
picked mechanically, so there are both green, unripe beans and red,
ripe beans mixed together. This makes a big difference in the quality
of the final product.
After carefully
selecting the beans, the ultimate, and perhaps most important, process
begins – roasting.
Though the kind
of bean used in the coffee determines how the coffee will taste, the
way and amount of time the coffee beans are roasted directly effects
the coffee’s flavor.
Roasted coffee beans double in size and turn brown. As you can imagine,
the longer the bean is roasted, the darker it will get. Coffee beans
are roasted from 10 to 20 minutes at 400 to 425 degrees F. When the
oven reaches temperatures of 400 F, the beans crack. After the beans
crack a second time, they are removed from the ovens and cooled immediately.
Roasting the beans
brings out the oils to the surface. This is called pyolsis. The longer
the roast, the less caffeine and less acidity the bean has – so
dark roasted beans have less caffeine than lighter ones. (Contrary to
what many people believe). Keep in mind, however, the amount of caffeine
you ingest also depends on the preparation of your coffee. If you use
a lot of coffee with little water, you’ll have a higher amount
of caffeine and stronger coffee.
Moreover, a darker
roasted bean might mask the flavor of a bean of poor quality or low
in flavor. It makes sense, then, that beans of higher quality and better
flavor are usually lightly roasted (cinnamon, American, or city roasted).
Lightly roasted beans also conserve better as fewer oils come to the
surface when the beans are roasted for less amount of time.
Let’s take
a look at labels used on coffees to describe how they are roasted, the
physical characteristics and taste characteristics each kind of roasted
bean has:

In Colombia, coffee
beans are graded according to their quality. Supremo, Excelso, Extra,
Consumo, and Pasilla are the five grades of Colombian coffee beans from
the highest quality to the lowest quality. Pasilla beans are not used
for the International market, but for the national market.
