7. How To Make
Drink From
Coffee Beans
To make a drink from coffee beans, the beans must first be specially prepared by drying the beans and then roasting. The
beans are dried a short time after they are picked. This preserves them and makes them ready to be packed or roasted.
Before the beans are made into a drink, they must roasted are ground (crushed into tiny pieces in a coffee mill). When the
ground coffee is placed into boiling water, the flavour and dark brown colour of the beans goes into the water.

8. Two Main Types Of Coffee Plants
The
Coffea
Arabica
The
Coffea
Robusta

9. The Coffea
Arabica
The Coffea Arabica,the most common. In the past, people gave names to new Arabica coffees from the portthey came
from. The two oldestArabica coffeesare "Mocha" and "Java".Today,names are more specific.They tell us the country,
region,and sometimes even the property where they come from.

10. The Coffea Robusta
Robusta is cheaper and has more caffeine than Arabica and it is used in
many commercial coffee products.But Robusta tastes bitter and acidic,
so people only drink it with other things. Better quality Robustasare in
some espresso blends.

11. What Is Espresso?
Espresso isa type of Italian coffee that is concentrated.In order
to make espresso,coffee beans are powdered and hotwater is
added under high pressure.
Usually,espresso is made using 7 grams of coffee beans.It gives
espresso a very strong flavor.Because espresso is so strong, it is
usually mixed with other coffee drinksin small amounts.

12. Ways Of Preparing Coffee
Aging Roasting Grinding Brewing

13. Aging
Definition
Some sorts of coffee taste better if the beans are "aged". This
means that after they are picked,the beans are dried and then
kept from three to eight years.
This "aging" gives the coffeea less acidic taste. Coffee that has
been aged is often mixed or "blended" with other coffeethat is
not aged.

14. Roasting
Roasting is one of the important stages in making coffee
beans into coffee.When a coffee bean is roasted,it grows
nearly two times bigger and changes fromgreen to yellow
to brown.

15. The Length Of Time The Coffee Beans Are Roasted
The length of time that the coffee beans are roasted makes the coffee taste different.Some types
of coffee,such as Mocha and Java, are roasted for a short time. It iseasy to tell from the flavour
where the coffee is from.When coffee is roasted for a long time, it is harder to tell the different
types apart. Green coffee beans can be bought and roasted at home in the oven.

17. What Is
Grinding?
Before the coffee is made into a drink,it is"ground" in a small grindingmachine called a
"coffee mill".The coffee mill breaks the beans into very small pieces.
Coffee isturned into a drink in several differentways. For some ways of making coffee,such
as "espresso" itis best to have the coffee ground into fine powder butfor other types of
coffee-making, such as"filtered coffee",the coffee is in larger piecesto stop it goingthrough
the filter.Finely ground coffee makes a stronger taste.W W W . G O R E V A . C O M

18. Brewing
Coffee is made into a drink by putting the coffee into
boiling water. This is called "brewing" coffee.

19. Four Popular
Ways To
Brew Coffee
Boiling
Pressure Steeping
Gravity

20. Boiling
The coffee and the water are put into a poton top of the stove and boiled
slowly together. This way of making coffee has been used for hundreds of
years. It is the way that coffee is usually made in the Middle East, North
Africa,Turkey and Greece.
W W W . G O R E V A . C O M

21. Pressure Definition
The boilingwater is forced through the ground
coffee by a machine.This type of coffee is called
Espresso. Espresso is a very strong coffee that can
be used to make other coffee drinks.

22. Gravity
Filtered coffee is made by gravity because
the boilingwater falls from a machine onto
the coffee.
The coffee grounds are held in a paper or
metal "filter" that the water can run through,
but the little coffee piecescannot.
The water becomes coloured and flavoured
as it runs through the coffee and into a
coffee pot.

23. Steeping
Boilingwater is poured onto the coffee and it is allowed to stand for a little
while,until the water has taken the colour and flavour.This is often done in a
cafetière.
Another way of steeping coffee is to have coffee grounds in a small packet, the
right size to make one cup of coffee. The packet is placed in the cup and water
poured over it. Then the packet is removed.

24. Cafetière
Cafetière is a tall glass or coffee pot
which has a special filter inside that can
be pushed down when the coffee is ready
so that the person does not drink the
coffee grounds.

25. How People
Drink
Their Coffee
Black coffee is coffee with no milk
in the coffee.
White coffee is coffee with milk in
the coffee.
Espressois very strong coffee, it’s
often called a “short black”.
Americano is espresso with a lot
of hot water.

26. Instant Coffee
"Instant coffee" is a very quick way to make a cup of coffee to drink. It is made in a
factory and sold in jars or packets. The taste can be very different from fresh coffee.

27. When Do People
Drink Their Coffee?
In some countries,for example,those in northern Europe,people like having
coffee parties. At these parties,people have coffee and cake.
In many countries,people drink coffee at work.In the United States and
England, for example, people drink itin the morning. In other countries,such
as Mexico,people drink it in the evening to help them stay awake.

28. In February 2003, there wasa study in Denmark of 18,478 women to find out if coffee had an effect on pregnancy and birth.It wasfound that if
a woman drank between four and seven cups of coffee a day,it did not seem to make a bigchange to the number of babies that were born dead.
But the women in the study who drank eight or more cupsof coffee a day had three times as much chance of having a stillborn baby.
