The Green Coffee Bean
Most people drink coffee without knowing
much about it. It is the taste that they
get use to and then decide what they
like. Coffee comes made from the seeds
that are roasted from the coffee plant.
These seeds are commonly known as ‘Green
Coffee Beans’. They are actually a
berry. The ‘green coffee beans’ that are
collected from the coffee plantations
are sent to special places where they
are roasted, ground, and then finely
crushed to make coffee powder.
Depending on the quality of the coffee
bean will then depend on how it is
packaged and where it is sent to. The
green coffee bean must be picked
normally by hand from the coffee
plantations. This is done by laborers
who get paid by the bucketfuls. Since
coffee beans are a type of drupe, with
fruit flesh directly wrapping the coffee
bean, they first gather the coffee beans
and then the flesh of the coffee bean
must be promptly removed by soaking,
scouring and rubbing the bean. The
de-fruited coffee bean is then cleaned
with water which removes the sticking
fruit and additional sugars. It is only
then left ready for the drying process.
The green coffee beans are then spread
over a large concrete or rock plane,
where they are dried by air and
sunlight.
Coffee beans are given a categorization
of the beans. This is done by color and
size. Discolored, decayed and damaged
beans are removed at this point and
thrown away.
The process of going from the Coffee
Berry to the dry green coffee bean can
be relatively long and may even involve
some fermentation.Once this has been
completed the green coffee beans should
be stored in some sort of container that
will allow it to breathe and not impart
another flavor to the beans: burlap
bags, paper bags, etc. Plastic
containers are never used for obvious
reasons. The coffee beans are stored at
room temperature and out of direct
light. They may be kept for a long
period of time. Because of their light
weight they are easy to ship abroad.
There are polyphenols in green coffee
beans which act to help reduce free
oxygen radicals in the body. The bean
extract is sometimes standardized to
more than 50%PRCTG% chlorogenic acid.
Coffee is a drink loved by millions, and
the green coffee bean is the start of
the production line. There are many ways
to produce the coffee, and depending
what you do with the green coffee bean
and where it comes from will determine
the taste and the outcome of the coffee.
The Roasting Process. Depending on how
log the coffee beans are exposed to the
sun will depend on what the flavour or
strength will be. The bean contains a
wide variety of chemical compounds
including proteins, fats, sugars,
dextrin, cellulose, caffeine, and
organic acids.
Some of these compounds volatise,
oxidize, or decompose as part of the
roasting process.The roasting process is
very important in producing an aromatic
cup of coffee. When roasted, the green
coffee bean expands to nearly twice its
initial size, changing in color and
density.
At this point in the roasting process,
the coffee beans will start cracking,
quite like popping popcorn. The bean
also expels moisture, and, upon reaching
400 degrees Fahrenheit, the color
changes to yellow and then to a light
‘cinnamon’ brown, and oil is released
from its interior.
This oil gives coffee its distinct
flavor. The greater the amount of oil
released, the stronger the flavor. The
coffee beans will crack during the
roasting process, which guides roasters
as to how to gauge the progression of
the roast. The bean will then continue
to expel more oil while darkening its
color, until such time it is removed
from the heat. The final product can be
crushed into savoury coffee powder.
Papua New Guinea is just one region that
grows the coffee berry. This is mainly
grown in the Highland regions rich
volcanic soils between the altitudes of
4,000 and 6,000 feet above sea level.
Just this fact alone will make the
coffee taste different from other areas
of growth. It is believed that every
factor that comes into play has a
bearing on the outcome of the coffee
bean. The altitude, the soil, the length
of time it is left unpicked, all
contribute to the production.
Papua New Guinea coffee is well regarded
by consumers for its uniqueness,
consistency and special flavor
characteristics. They export
approximately 2%PRCTG% of the annual world
green coffee bean production.
Papua New Guinea coffee beans are highly
sought, as they produce a distinct
floral and citric flavor and nutty body,
and are frequently used to blend with
other coffees to produce unique gourmet
coffees. Take a look at this website

Brazil – continues to be the largest
coffee exporter, although the green
coffee market has recently been flooded
with large amount of Robusta beans from
Vietnam. Robusta coffees, which were
traded in London at a cheaper price
compared to New York’s Arabica, are the
choice of large industrial clients
consisting of multinational roasters and
instant coffee producers; they favor
these coffees because of the less
expensive price. A rare and costly
variety of Robusta is the Indonesian
Kopi Luwak and the Philippine Kape
Alamid. Owing to the indirect pressure
exerted by the World Bank to the French
government, experts believe that the
influx of cheap green coffee resulted
from the crisis in pricing that started
in 2001, and continues to the present.
Robusta is the cheap stuff. It packs
lots of caffeine jolt, but offers only
one-dimensional, front-of-mouth flavour.
Much of it goes for instant, but a
surprising amount becomes the filler in
blends. Most industrial espresso
roasters say it gives a better crema, or
head, but this is rot – robusta is just
a way to keep costs down and drinkers’
nerves jangled. Vietnam is the major
robusta exporter, and has flooded the
market with cheap beans. Most “espresso
roasts” now include them, their blunt
flavour hidden by roasting beans almost
to the point of incineration.
Arabica beans have finer, more complex
flavours and are less
highly-caffeinated. As with wine grapes,
they include many sub-varieties and
variations in terroir, and different
skills in picking, de-fruiting, drying,
sorting, ageing, roasting and packing
the beans offer a coffee lover endless
opportunities for subtlety and surprise.
I haven’t found an instant coffee I
like, so won’t be mentioning one.
Where To Go For A Coffee In London. Dont
just use Starbucks or Costa Coffee.
There are plenty of hotels dotted around
London that have coffee afternoons. Try
one of htese and be pleasantly
surprised.
If you are in Central London then I
would recommend a visit to Connaught
Square, commonly known as ‘Connaught
Village’ just off the Edgware Road. It
is a 2 minute walk from Marble Arch tube
station, and 200 metres from the bottom
end of Hyde Park. There is a small
coffee shop on the corner of Connaught
Square called Markus Coffee. It has
recently been refurbished by the owner,
who has been blending and producing his
magnificent coffee for over 25 years.
Roasting takes place every day and the
fresh aromatic smell is amazing. It is
the best coffee in London. Well worth a
visit.
