The Long History of Chocolate – Or, How a Sacred Bitter Drink Became Everything, and Is Slowly Becoming Itself Again

There is a version of chocolate that has nothing to do with the purple foil wrapper, the Valentine’s heart box, the Easter egg cracked open before breakfast. That version is older, darker, more demanding. It arrives in a carved vessel, frothy and bitter, spiced with chili, smelling of something ancient and particular. To drink it was to participate in something sacred. To receive it was a mark of status, of favour, of proximity to the divine.

We have spent five hundred years diluting that drink. And only now, slowly, are we beginning to pay attention again.

Before Sugar: Mesoamerica and the Original Chocolate

Cacao has been cultivated in Mesoamerica for at least four thousand years. The Olmecs, one of the earliest complex civilisations in the region, flourishing from around 1500 BCE, are thought to be among the first to ferment, roast and grind cacao beans, using them in drinks and ritual preparations. Theobromine traces found on pottery from sites such as San Lorenzo confirm what archaeologists have long suspected: this was not an accidental discovery but a deliberate, sustained practice.

The Maya refined what the Olmecs began. By the Classic period, cacao drinks, thick, frothy, often mixed with chili, honey or water, appeared in daily life, in ritual, and as currency. Most households could access cacao in some form; it was not exclusively the preserve of elites. What made it sacred was not its rarity but its meaning.

The Aztecs gave chocolate its most formalised status. Cacao was associated with Quetzalcoatl and other deities. The beans themselves functioned as money. And the drink – xocolatl, bitter and cold and spiced – was reserved largely for nobility, warriors and ceremonial occasions. Emperor Moctezuma II was reportedly consuming it in considerable quantities when the Spanish arrived.

If you were an Aztec noble, drinking cacao from a carved vessel was a simultaneous act of economic display, spiritual participation and physical pleasure. The beans in your cup were also the currency in your treasury.

The Spanish Encounter and the Addition of Sugar

Hernán Cortés and the Spanish conquistadors encountered cacao in the Aztec empire in 1519. They did not immediately know what to do with it. The drink was bitter, cold, unfamiliar. But they recognised its importance, ceremonial, economic, nutritional, and brought it back to Spain.

What the Spanish did, almost immediately, was add sugar.

This single intervention changed everything. The bitter sacred drink of Mesoamerica became a sweetened hot beverage served at the Spanish court. Friars and physicians framed it as medicinal. Aristocrats consumed it at breakfast. For more than a century, Spain largely kept chocolate within its own empire – but by the 17th century it had spread to Italy, France and beyond, carried by imperial trade routes and a growing appetite for sweetened colonial goods.

In France, Louis XIV granted a royal patent in 1659 to manufacture drinking chocolate. The first Parisian shop specifically for chocolate opened in 1671. By the early 18th century, chocolate houses had become centres of aristocratic sociability: fashionable, refined, associated with polite society in the same way coffee houses were associated with commerce and debate.

Theologians debated whether drinking chocolate broke religious fasts. Physicians argued about its humoral properties. Everyone, regardless of their position, agreed that chocolate was significant — medicinal, aphrodisiac, luxurious, morally complex.

The Solid Bar: Fry’s, 1847

For most of its European life, chocolate was a drink. The idea of eating it, of biting into it, did not exist until the industrial age made it possible.

J. S. Fry & Sons, a Quaker family firm in Bristol, had been manufacturing cocoa since 1761. In 1847, they achieved something that now seems obvious but was then genuinely new: they combined dutched cocoa, sugar and extra cocoa butter into a paste that could be moulded and set. The result was the first widely recognised solid chocolate bar.

It was still expensive. It was still relatively bitter. But it was portable, edible and scalable — and it opened the door to everything that followed.

The Quaker firms (Fry, Cadbury and Rowntree) were central to what happened next. John Cadbury had been selling drinking chocolate in Birmingham since 1824, framing cocoa as a wholesome, temperance-friendly alternative to alcohol. His son George built the model village at Bournville to house workers in decent conditions. In York, the Rowntree family, rooted in the same Quaker tradition, developed Fruit Pastilles, Elect Cocoa and a model of industrial paternalism that shaped how chocolate was produced and consumed in Britain for generations.

These were not cynical operations. The Quaker firms genuinely believed in what they were doing — in chocolate as social good, in industry as moral project. That belief shaped the product and its meaning. Chocolate became associated with respectability, with working-class nourishment, with the temperance movement’s vision of a better society.

Milk Chocolate: A Swiss Collaboration

The smoothness we associate with eating chocolate today came not from Britain but from Switzerland, and from an unlikely collaboration between neighbours.

Daniel Peter, a chocolatier working in Vevey, had been trying for years to add milk to chocolate. The problem was water content, milk caused the mixture to seize and spoil. His neighbour, Henri Nestlé, had developed a process for condensed milk for infant food. By using Nestlé’s sweetened condensed milk, Peter achieved something stable: the first successful solid milk chocolate, around 1875.

His “Gala Peter” bar, launched in 1887, became the first widely successful milk chocolate brand. Combined with Rodolphe Lindt’s invention of conching in 1879 — a process that smoothed and aerated chocolate to a new level of silkiness, milk chocolate accelerated the shift from bitter, complex, elite product to smooth, sweet confection aimed at mass markets.

By the early 20th century, Cadbury’s Dairy Milk, various Rowntree lines, and their international equivalents had thoroughly embedded chocolate into everyday Western diets. It was no longer sacred. It was no longer even particularly special. It was everywhere.

The Commodity Years

Industrialisation brought chocolate to everyone and flattened it in the process. Large factories, mechanised production and globalised sourcing of cheap bulk cacao, predominantly from West Africa, reduced costs dramatically and standardised flavour to the point of anonymity.

The big firms competed through advertising and branding rather than through cacao quality. Chocolate became associated with childhood, with romance, with national identity, with everything except the bean itself, the farm it came from, the people who grew it.

This massification had structural ethical costs that are still being reckoned with today: child labour, low cacao prices, exploitative sourcing. Consumer-facing brands emphasised purity and wholesome imagery while the supply chain remained largely invisible.

Chocolate, by the mid-20th century, was a paradigmatic modern commodity: affordable, ubiquitous, emotionally loaded, and almost entirely detached from its origins.

The Return: Single Origin and Bean-to-Bar

The reversal began quietly. In the 1980s and 1990s, a handful of European makers, most notably the French firm Bonnat, began making single-origin chocolate: bars produced from beans sourced from a specific country or region, with the origin named and celebrated on the label. In 1998, Valrhona launched a vintage-dated single-origin chocolate from a specific Trinidadian plantation, linking chocolate explicitly to notions of terroir, harvest year and fine flavour.

The language was borrowed from wine. The intention was the same: to reattach the product to its place, to make geography and season and soil legible in the flavour of what you were eating.

The bean-to-bar movement grew from these beginnings. By the 2000s and 2010s, small producers in the USA, UK, Scandinavia and elsewhere were sourcing their own beans, controlling fermentation and roasting, experimenting with processing, and telling detailed stories about the farmers and origins behind each bar. Amedei in Italy. Askinosie in Missouri. Pump Street in Suffolk.

These makers do not just buy chocolate and melt it. They begin with the bean, and every decision along the way is deliberate, attentive, oriented towards flavour and ethics simultaneously.

What This Means for How We Eat It

There is a particular pleasure in eating a well-made single-origin bar slowly. Not unwrapping it in the car, not breaking off a square in front of the television. Sitting with it. Letting it melt. Noticing what happens, the fruit notes, the earthiness, the lingering bitterness that resolves into something floral or woody or sharp.

This is what chocolate was always capable of. The bitterness the Spanish tried to sweeten away, the complexity the Quaker firms standardised out of existence, the origin the industrial commodity chain rendered invisible, all of it is still there, in the right bar, grown in the right place, made with the right attention.

To eat chocolate slowly is, in a small way, to recover something that was almost lost.

At Slow Pleasure, we recommend single-origin and bean-to-bar chocolate wherever possible. Look for bars from Pump Street, Dormouse, Rózsavölgyi Csokoládé or Mast Brothers as a starting point. The difference, eaten properly, is considerable.
