7. Harvesting Cocoa & Cocoa processing
How Chocolate is Made
Step #1: Plucking and opening the Pods
Cocoa beans grow in pods that sprout off of the trunk and branches of
cocoa trees.
The pods start out green and turn orange when they are ripe.
After the cocoa pods are collected into baskets, they are split open
and the cocoa beans are removed
Fresh cocoa beans are not brown at all, they do not taste at all like
the sweet chocolate they will eventually produce.

8. Step #2: Fermenting the cocoa seeds
Now the beans undergo the fermentation
processing.
 They are either placed in
large, shallow, heated trays or covered with
large banana leaves.
 If the climate is right, they may be simply
heated by the sun.
 Workers come along periodically and stir
them up so that all of the beans come out
equally fermented.
 During fermentation is when the beans
turn brown. This process may take five or
eight days.

9. Step #3: Drying the cocoa seeds
After fermentation, the cocoa seeds
must be dried before they can be
scooped into sacks and shipped to
chocolate manufacturers.
 Farmers simply spread the fermented
seeds on trays and leave them in the
sun to dry.
 The drying process usually takes
about a week and results in seeds that
are about half of their original weight.
The dried and roasted Cocoa beans

10. Manufacturing Chocolate
Step #1: Roasting and Winnowing the Cocoa
The first thing that chocolate manufacturers
do with cocoa beans is roast them(develops
the colour and flavour).
 The outer shell of the beans is removed,
and the inner cocoa bean meat is broken into
small pieces called "cocoa nibs.“
The roasting process makes the shells of
the cocoa brittle, and cocoa nibs pass
through a series of sieves, which strain and
sort the nibs according to size in a process
called "winnowing".

11. Step #2: Grinding the Cocoa Nibs
Grinding is the process by which cocoa
nibs are ground into " cocoa liquor“.
 The grinding process generates heat
and the dry granular consistency of the
cocoa nib is then turned into a liquid as the
high amount of fat contained in the nib
melts.
 The cocoa liquor is mixed with cocoa
butter and sugar. In the case of milk
chocolate, fresh, sweetened condensed or
roller-dry low-heat powdered whole milk is
added.

12. Step #3: Blending Cocoa liquor and
molding Chocolate
After the mixing
process, the blend is further
refined to bring the particle
size of the added milk and
sugar down to the desired
fineness.
 The Cocoa powder or
'mass' is blended back with
the butter and liquor in
varying quantities to make
different types of chocolate.
