NAME
Coffee - The Elixir of Life
SYNOPSIS
coffee ( from "Dick's Coffee House" on WWW )
DESCRIPTION
Coffee - what would I do without it! Here are some fact
about my favorite drink gathered from all over Internet.
Get yourself a cup of java and start reading.
Index:
* The beans
* Processing
* Roasting
* Brewing
* Feedback
Did you know that there are three different coffee plants?
* Coffea Arabica
The best and most tasteful. Originally from Ethiopia
but grown on many places around the world. Arabica
generally grows on high altitude and are of higher
quality then the other two. Depending on where the
coffee has grown, the taste will differ. The cleaner
flavor of Arabica beans may taste strange to a novice
but are much appreciated by experts and coffee lovers
(like myself).
* Coffea Robusta (or Coffea Canephora)
This plant will produce a less characteristic taste
and is also less expensive. Robusta, best grown at
altitudes below 900 meters, is the main component in
canned coffee in order to keep the price at an
affordable level.
* Coffea Liberica
Only a few percent of all coffee comes from this
rather unusual, west-African plant.
Althought Brazil produces nearly 35 percent of the world's
coffee, the majority of the coffee has what you might call
a non-distinguishable, sweet, and neutral taste.
Colombia, the world's second coffee producer, produces
coffee with a much richer flavor. Still sweet with a
slight acidity. African coffee from countries like
Ethiopia, Kenya, and Tanzania often have a fruity, winey
tast, with a mild acidity, whereas coffee from Sumatra and
New Guinea have a more pronounced acidity. Java, however,
has very little acidity and can best be described as
spicy. Jamaican coffee are rich full-bodied and well bal-
anced. Jamaica Blue Mountain is often regarded the best
coffee in the world. I haven't tried it myself yet.
The flavor of the month in my kitchen is Guatemalan
Antigua.
A coffee bean contains 1.1 - 1.4 % coffeine. Actually,
Robusta beans has a higher caffeine concentration than
Arabica. I've been trying to figure out how much caffeine
there is in the actuall drink but this seams to be rather
a tricky question. At least I haven't been able to find a
precise answer. Here's what I came up with:
Miligrams of caffeine per 12 oz can of soda
* Jolt Cola 71
* Coca Cola 45
* Pepsi Cola 37
Compare that with a "regular" cup of coffee or tea.
Miligrams of caffeine per cup
* Coffee 90 - 150
* Instant 60 - 80
* Tea 40 - 60
Processing
The coffee tree produces its first full crop after five
years. The flavor of the bean will vary depending on
where the tree has grown, but also on the size of the
bean, the density, and the water content. After the har-
vest, often done by hand, the beans are classified by den-
sity by putting them in water and see how quick they sink.
More developed beans have higher density and will sink
more rapidly, while the less developed, lighter beans will
sink slower.
After being washed, the beans are spread out to (sun)dry.
The beans are then aged in bags from 90 days up to several
years(!) The green beans, as they are called, are now
sorted by size once again (by hand) to remove bad beans
and to ensure ideal uniformity. The beans are now ready to
be exported (or roasted). Green beans will hold for up to
a year if kept cool and dry.
In Sweden, green beans can be bought at certain coffee
and/or tea shops and there is probably a place even in
your town.
Ask around!
Roasting
Roasting is the process of turning a green bean into a
brown bean. This is done by exposing the beans to high
temperature in a rotating chamber. During the roasting,
starches are broken down to simple sugars, which then are
caramelized back to complex sugars. Temperature range
from about 190 C to 220 C.
The beans will lose some of their fruit acids, floral aro-
matics, and caffeine during the roast process. They will
also lose up to 20% of their weight. However, they will
gain smoothness, a caramel taste, and a bitter edge. They
also nearly double in size.
If you have bought green beans, you can roast them your-
self, either in the oven or by using an ordinary frying
pan. When using a frying pan make sure you keep stirring
or the beans will get burned on one side. I usually roast
the beans on high temperature until the first crack (5-6
minutes). Then I turn the heat down and continue another
two to six minutes, depending on the beans used. Here you
can experiment a lot! When the beans are done, cool them
down quickly.
[Stop when the bean has the desired color]
By blending and roasting different beans together you can
create your favourite flavor. Take your time to get to
know the each individual sort before starting blending and
remember that roasted beans should be kept cool and dry
and consumed within a week. Never grind until brewing
time!
Brewing
Before you can brew your java you actually have to grid
your beans. Don't grind more than you need because when
grinded the coffee loses its unique flavor within a week.
I'm not going to talk much about grinding since it is
quite straight forward. Just make sure that you grind it
quite coarse, especially if you are using a French press
(which I highly recommend).
To make a nice cup of coffee you need two things: coffee
and water. Since water makes up roughly 98% of the cup
it's important to use fresh, clean, cold water. If the
water is bad your coffee will taste badly. Period. Make
sure all your equipment (the grinder, the French press,
the cup) is cleaned carefully.
There are many ways of brewing a nice cup of coffee. The
percolator is not one of them since it boils the coffee.
The French press is the preferred method by many in the
coffee industry. If you rather use a paper filter you can
benefit greatly by gently rinsing the filter until the
papery smell is gone. It will also speed up the brewing
process, which generally is a good idea.
The most common mistake is to use too little coffee. The
rule of thumb is to take two tablespoons per 6 ounces of
water. Start there and experiment to find what is best for
your beans, your grind, your brewer, your water, etc.
After all, if you don't like it, it isn't a good cup of
coffee.
Pre-heat the brewer by filling it with hot water from the
tap. Boil some water, grind your beans, pour the water
from the brewer, and add the grounds. Pour hot (but not
boiling) water over the grounds and stir for a couple of
seconds. Let the coffee brew for some minutes and then
press down the plunger and serve.
