How Chocolate Is Made: From Pod to Bar

Most of us know chocolate as a finished bar, a bonbon or a beautiful box of chocolates. Few of us stop to ask how chocolate is made, or what it looked like before it ever reached a shelf. Long before chocolate reaches our kitchen at Kakawa, it begins as something you might not expect: a colourful fruit growing on a cacao tree. From fermentation and roasting to grinding and tempering, the journey from pod to chocolate is a wonderful mix of agriculture, science and craftsmanship, and we never tire of it.

It Starts With a Cacao Pod

Cacao trees grow in warm, humid regions close to the equator, in what is commonly known as the cocoa belt. Australia is not the first place that comes to mind when we think of cacao, yet it is also grown in tropical northern Australia, particularly Queensland, a fact that still surprises most people we tell.

Crack open a cacao pod and you will find beans surrounded by soft, white pulp. That pulp is sweet, juicy and fruity, a little like lychee or rambutan, and honestly, often more delicious than the beans themselves. Raw cacao beans, by contrast, are bitter, fruity and astringent, with little resemblance to the chocolate we know and love.

A cacao pod typically holds only a few dozen beans. Depending on the pod, the cacao percentage and the size of the finished bar, roughly one pod's worth of beans can go into an 80 to 100g chocolate bar. Next time you unwrap one, it is worth pausing on that. The bar in your hand may represent an entire fruit from a cacao tree.

Fermentation, Drying and Roasting

After harvesting, the beans and pulp are removed from the pods and fermented for several days, one of the most important stages in developing chocolate flavour. Natural reactions inside the beans quietly create the flavour precursors that later become recognisable during roasting. Depending on the cacao variety, where it was grown and how it was fermented, chocolate can eventually remind us of berries, tropical fruit, nuts, flowers, spices, caramel or coffee, flavours that come from the cacao itself rather than anything added. Good chocolate flavour begins at the farm, not in the factory.

Once fermented, the beans are dried, then roasted. Much like coffee, roasting develops aroma and flavour while softening raw acidity and bitterness, though every cacao behaves differently. We recently trialled a small batch of Solomon Islands beans at Kakawa, and we were taken with their gentle fruitiness and acidity from the very first taste. Rather than reach for a heavy roast, we chose a gentle one to preserve those characteristics. It taught us something worth remembering: roasting is not about making every cacao taste the same, but about understanding what is already inside the bean and deciding what to preserve, soften or develop.

From Bean to Liquid Chocolate

After roasting, the beans are cracked and their shells removed to reveal cacao nibs. Commercial makers separate the shells from the nibs through a process called winnowing. As the nibs are ground finer and finer, their natural cocoa butter is released and the cacao slowly transforms from crunchy pieces into a thick, flowing paste called cocoa mass or cacao liquor, which, despite the name, contains no alcohol. This transformation sits at the heart of the bean to bar chocolate process, and it is one of the more satisfying stages to watch.

Dark, Milk and White Chocolate

From here, different ingredients combine to create the chocolate types we know. Dark chocolate is generally cocoa mass, sugar and often extra cocoa butter. Milk chocolate adds milk ingredients for a softer, creamier flavour. White chocolate contains cocoa butter, sugar and milk ingredients but no cocoa solids, which explains its pale colour and different flavour. Two bars can both say seventy percent dark chocolate and still taste completely different, because percentage alone does not tell you where the cacao came from or how it was fermented and roasted.

Refining, Conching and Tempering

At this stage, chocolate can still feel surprisingly gritty. Refining reduces the particles of cacao and sugar until the tongue no longer perceives them as individual grains, giving good chocolate its smooth, silky texture. The chocolate is then conched, mixed and worked continuously, often for many hours, to reduce moisture and unwanted aromas while the flavour becomes smoother and more balanced.

One last piece of science remains, and it happens to be our favourite part to explain. Cocoa butter is polymorphic, meaning it can solidify into several different crystal structures, much like diamond and graphite, both carbon, arranged differently, with remarkably different properties. By carefully controlling temperature, chocolatiers encourage cocoa butter to form the crystal structure they want. That is tempering. Properly tempered chocolate has a beautiful shine, releases cleanly from its mould and gives that satisfying snap when broken. The chocolate itself has not changed. The way its crystals are organised has, and that small difference makes all the difference.

From Chocolate to Chocolates

This is where our everyday work at Kakawa begins. We choose different couvertures for their origin, flavour and character, then temper them and combine them with ganaches, pralines, caramels, fruits, nuts and spices to create our chocolates, one batch at a time.

So the next time you pick up a bar or a bonbon, take a moment to think about where it started: a pod on a tree near the equator, fermented, dried, roasted, ground, refined, conched and finally tempered by a chocolatier, long before it reached the box in front of you. Chocolate may look simple, but behind every piece is agriculture, science, time and craftsmanship, and we hope that makes the next piece taste just a little more interesting.

Frequently Asked Questions

How is chocolate made from cacao beans?
The process of making chocolate begins with harvesting cacao pods. The beans are fermented and dried, then roasted, cracked and separated from their shells. The cacao nibs are ground, refined and conched with other ingredients to create smooth chocolate. Finally, the chocolate is tempered before being moulded into bars or used by chocolatiers to create bonbons and other chocolates.

How many cacao beans does it take to make one chocolate bar?
A cacao pod usually contains a few dozen beans. The exact amount varies depending on the cacao variety, pod size, chocolate percentage and size of the bar, but roughly one cacao pod's worth of beans can go into an 80 to 100g chocolate bar.

What does bean to bar chocolate mean?
Bean to bar chocolate is made by a chocolate maker who takes cacao beans through the major stages of chocolate production, such as roasting, grinding, refining and conching, rather than starting with finished couverture chocolate. Chocolatiers like Kakawa typically begin with couverture and use it to create bonbons, ganaches, pralines, bars and other chocolate creations.

What are the main types of chocolate?
The three classic types of chocolate are dark, milk and white. Dark chocolate contains cocoa solids and cocoa butter, milk chocolate also contains milk ingredients, while white chocolate contains cocoa butter but no cocoa solids. You may also come across newer styles such as ruby chocolate, known for its naturally pink colour and fruity, tangy flavour, and caramelised white chocolate, which develops rich caramel, biscuit and toasted notes through caramelisation. Different recipes, cacao origins and production methods give each chocolate its own distinctive flavour, sweetness and texture.

Where do chocolate flavours come from?
Many chocolate flavours come naturally from the cacao itself rather than from added flavourings. Cacao variety, growing region, fermentation, drying and roasting can all influence the final flavour. That is why one dark chocolate might taste fruity or floral while another can remind you of nuts, caramel, spices or coffee.
