| The beans of different origin are sorted
and then cleaned and roasted, which is the key to excellent
chocolate flavor. The seed loses much of its moisture
and turns a deep brown color. The roasting also simplified
the separation of shell and nibs. |
 |
 |
| Following the roasting process, the
beans go through a machine called a winnower, which
removes the outer hulls and separates the nibs of
the beans by size. The nibs are the basic product
used for chocolate production. 
The nibs are then milled—crushed by heavy steel
discs. This process grinds them into a thick paste
called chocolate liquor.
Some of the chocolate liquor is placed to large presses,
which squeezes out the cocoa butter. This fatty, yellow
substance can be added to dark or milk chocolates,
used as the basis for white chocolate, or used in
cosmetics and medicine. The remaining solid cocoa
is crushed, ground and finely sifted into cocoa powder—the
product used in beverages, cooking, and baking. |

Cocoa
paste, cocoa butter, sugar and milk are the four basic ingredients
for making chocolate. By blending these ingredients, with specific
recipes, the basis of every chocolate product is made: dark chocolate,
milk chocolate, and white chocolate. The extra cocoa butter keeps
the chocolate solid at room temperature. This explains why chocolate
doesn’t spoil—and why it melts in the warmth of your
mouth.

Next, the chocolate mixture goes through a series of steel rollers
which refines the chocolate and breaks down the tiny particles
of cocoa, and sugar. The refined chocolate paste is poured into
a vat in which a large heavy roller kneads, blends, and grinds
the mixture.
In this process, called “conching”, the paste is
refined again by agitating, heating and mixing, giving the chocolate
a silky texture and pure characteristics. Aerating the paste allows
acids and moisture to evaporate causing the bitter taste to gradually
disappear and the flavor is to be fully developed.

| Finally, the refined chocolate is cooled and warmed
repeatedly in a process called “tempering.” This gives
chocolate its glossy sheen, and ensures that it will melt properly.
The finished chocolate is molded and packaged to be used by chocolate
manufacturers to create the bars, truffles, and other fine confections
that sweeten our life. |
