Today, cacao farmers face increasing pressure from climate change, crop disease, aging trees, and fluctuating prices, while worldwide demand for chocolate continues to increase.
In West Africa, where most of the world's general use cocoa is grown, irregular rainfall and disease are already reducing harvests.
In 2026, new technologies like lab-grown cocoa and cocoa cell culture are being explored as early-stage approaches that could help reduce pressure on traditional cocoa supply chains facing these issues (1).
This raises a very important question: what happens to trees, seeds, and genetic diversity as certain chocolate brands move further away from traditional farming methods?
Every cup of chocolate begins with a tree and a seed.
As the chocolate industry evolves, understanding the origins of cacao, and what is at stake, has never been more important.
What Is Lab-Grown Cocoa?
Lab-grown cocoa, sometimes referred to as “cocoa cell culture”, is created by taking the cells of the cacao plant and growing them within controlled environments such as bioreactors. The goal is to produce cocoa compounds without growing a full cacao tree (1). Supporters argue these technologies could help address supply shortages, climate pressures, and rising demand.
Although still in early development, they are raising important questions about the future of chocolate and the role of farming and biodiversity within its production.
The Difference Between Real Cacao and Lab-Grown Alternatives
Traditionally grown cacao begins with a living tree, Theobroma cacao, growing in relationship with the soil, sunlight, water, and biodiversity around it. Every tree begins with a seed, and for thousands of years farmers have carefully cultivated and passed down cacao varieties, allowing them to adapt and evolve over generations.
Lab-grown cocoa takes a different path. Instead of growing a tree from seed, it is produced from selected cacao cells in a controlled laboratory environment.
The difference begins at the source: one comes from living ecosystems and generations of farming knowledge, while the other is created through modern technology.
For many cacao lovers, that distinction is about more than how cocoa is produced. It is about maintaining a connection to nature, farming, and the origins of cacao.
Every Cup Begins With a Seed
Long before chocolate became a global industry, it was a tree.
For thousands of years, cacao has been cultivated, protected, and passed down through generations of farming families (2). Over time, different varieties developed traits suited to their environments, some more resistant to drought, others more resistant to disease, and some valued for their particular flavour profiles.
Each cacao tree begins with a seed, and each seed carries small differences shaped by both nature and human selection over generations.
This diversity is one of cacao’s most important strengths. According to archaeogenetic research, cacao’s genetic history reflects long periods of cultivation, movement, and exchanges between regions, resulting in the wide range of varieties we see today (3).
Some cacao varieties handle droughts surprisingly well. Whilst other varieties show resilience to disease. Some produce distinctive flavour profiles found nowhere else in the world (4).
Genetic diversity helps cacao adapt. Traits like disease resistance and climate tolerance may become increasingly valuable as growing conditions change.
Why Preserving Cacao Genetics Matters
Biodiversity is a major factor in keeping cacao trees healthy. Different varieties respond differently to drought, disease, and changing conditions. That variation is what helps cacao adapt over time, which is why traditional and heirloom varieties still matter for the future(4).
As farming conditions change, seed diversity helps preserve resilient cacao trees for future generations. Once lost, this diversity is difficult to restore.
It's about keeping more ways of growing cacao alive.
Supporting the People Behind Cacao
Behind every cacao tree are farming families who have spent generations cultivating the crop and preserving agricultural knowledge.
Millions of people around the world depend on cacao for their livelihoods, particularly smallholder farmers in tropical regions.
Supporting sustainable and organic farming practices not only helps to protect communities, but also to protect the ecosystems that they depend on. Healthy cacao systems are more than production; they are about long-term relationships between the land and people.
This means that cacao is more than a traded good; it is determined by culture, ecology, together with the livelihoods it sustains.
Looking After the Future of Cacao
Like many food systems right now in 2026, chocolate is being shaped by innovation.
New technologies may help with some of the challenges the industry is facing, and it’ll be interesting to see where they actually land in practice, especially once consumer choices start influencing those outcomes more directly.
It’s also important to not lose sight of what cacao already is. Real trees, living seeds, and a level of biodiversity built up over thousands of years through domestication, natural adaptation, and farming traditions, including Indigenous cacao cultivation systems. That still feels essential to how the system holds together.
Every cup begins with a seed, and in that way, it helps support farming families, biodiversity, tradition, and the cacao tree itself. This is what keeps cacao systems going.
As the chocolate industry evolves, we hope both seed and story are protected for generations to come.
The future of chocolate may change, but cacao should always begin with seeds rooted in living systems.
