The very mention of chocolate fills the mouth with sweetness. Some people like it sweet, while others like dark chocolate with a slight bitterness. Sometimes it has a hint of coffee, sometimes it tastes like nuts and berries, but have you ever wondered where these different tastes come from?

Most people believe that the taste of chocolate comes directly from cocoa beans, but the reality is much more interesting than this. Yes, the real magic of chocolate is hidden in the process of fermentation, where microbes give a new form to the taste of chocolate. Let's know about it in detail.

The taste of chocolate does not come only from beans

Cocoa beans are actually bitter. If they are eaten directly, the taste will be bad. In such a situation, after removing these beans from the cocoa fruit, they are left in a heap for a few days. This is where the fermentation process begins. Yes, the yeast and bacteria present in the environment become active on the pulp of the beans. These microorganisms break down the structure of the beans and create compounds that later give the special flavour of chocolate during roasting.

The hidden artists behind the taste of chocolate

Scientists believe that microbes are the real artists of the taste of chocolate. A study conducted in different districts of Colombia revealed that the taste of beans from every region is different. This difference does not come from the breed of beans, but from the active microbes there.

The taste of chocolate becomes even deeper and richer with certain special yeasts like Torulaspora and Saccharomyces. That is, just as different instruments in music combine to make the tune special, in the same way, microbes combine to give chocolate its unique taste.

Why does the taste change?
The environment of every region is different - there is a difference in temperature, humidity, and pH level. These conditions determine which type of microbes will be more active. The result is that beans with the same genetic background give different tastes in different areas.

That is, it would not be wrong to say that the taste of chocolate depends not only on the variety of beans, but also on the soil, weather, and fermentation process of that place. This is the reason why different flavors are felt in chocolates from New York, Switzerland, or Colombia.

Scientists' investigation and results

Scientists of Nottingham University got the "cocoa liquor" prepared from cocoa beans tested by a panel. It was found that the beans from some districts had flavors like nuts, berries, and coffee, while the beans from some places tasted bland and bitter. This proved that the difference in flavor is due to microbes and fermentation.

Designer chocolate
Now scientists are moving further in this direction. Their goal is to make "designer chocolate" by selecting and controlling the right microbes in fermentation.

Imagine, if such a chocolate comes in the market in which the taste of sweet berries, thick coffee flavor, or a glimpse of nuts is pre-determined, then it will be a new experience for the consumers. Just like we can choose different flavors of ice cream or coffee today, similarly, in the future, chocolate can also be available in completely customized tastes.

Not just taste, but culture too

The taste of chocolate is not just the result of a scientific process, but it is also linked to culture and tradition. People in different countries like different types of chocolate. For example, people in Europe like smooth and sweet chocolate, while in America, there is more demand for dark and slightly bitter chocolate.

With the understanding of fermentation and microbes, it will now be possible to prepare chocolate according to every culture and market.

As sweet as the taste of chocolate is, its science is equally deep and interesting. Small invisible organisms, i.e., microbes, are the real artisans who turn bitter beans into wonderful chocolate. This process of fermentation decides whether your chocolate will taste like nuts, coffee or berries.
