Chocolate is one of the world’s most beloved foods, associated with pleasure, celebration and comfort. Yet behind every chocolate bar lies an increasingly vulnerable supply chain. Climate change, crop disease, rising cocoa prices and concerns about working conditions have encouraged scientists to explore an alternative: lab-grown, or more accurately, cell-cultivated chocolate.
Unlike conventional chocolate, which relies on cocoa beans harvested from trees, cultivated cocoa begins with cells taken from a cocoa plant. Scientists grow these cells in controlled environments, using nutrients and specialised tanks called bioreactors to produce cocoa ingredients, including cocoa butter and cocoa solids. The aim is to reproduce the taste, texture and melting qualities of traditional cocoa while reducing dependence on conventional farming.
Companies and Brands Leading the Change
Several companies are helping bring this technology closer to commercial reality.
Celleste Bio and Mondelēz International: In April 2026, Israeli biotechnology company Celleste Bio announced milk chocolate prototypes made using cell-cultivated cocoa butter, produced in collaboration with Mondelēz International, the parent company of British brands Cadbury and European brands such as Milka. This is an important development, but it does not mean Cadbury or Milka products currently contain cultivated cocoa.
Puratos and California Cultured: Belgian ingredients company Puratos announced plans to launch a professional chocolate product containing cultivated cocoa in the United States towards the end of 2026. Its partner, California Cultured, develops cocoa ingredients using plant-cell technology. This could eventually allow European chocolate manufacturers and food businesses to access cultivated cocoa ingredients.
Kokomodo: This biotechnology company is developing cultivated cocoa ingredients designed to improve supply reliability and reduce dependence on conventional cocoa production.
These developments show that British and European chocolate businesses are connected to the emerging industry. However, no major British or EU consumer chocolate brand has been confirmed as selling a mainstream chocolate bar containing cultivated cocoa as of October 2026.
The Advantages
First, cultivated cocoa could help reduce pressure on forests and agricultural land, although its environmental impact will depend on energy consumption, water use and production methods.
Second, it could create a more reliable cocoa supply, helping manufacturers manage climate disruption, crop disease and price volatility.
Third, it offers opportunities to address ethical concerns associated with parts of the cocoa supply chain, including child labour and inadequate farmer compensation. These benefits will depend on responsible implementation and continued support for cocoa-growing communities.
Finally, controlled production could provide consistent ingredient quality and encourage new flavours, textures and chocolate products.
Integrating Cultivated Chocolate into Society
Public acceptance will depend on trust, transparent labelling, independent safety assessments, competitive pricing and convincing taste. In Britain and the European Union, regulatory approval must be secured before products requiring novel-food authorisation can be sold.
The industry must also consider the livelihoods of cocoa farmers, particularly in West Africa. Replacing traditional agriculture without supporting affected communities could create new social inequalities.
Ultimately, cultivated chocolate should not necessarily replace traditional farming. It could complement existing cocoa production, diversify supply and offer consumers another choice. Its success will depend on whether it delivers genuine environmental and social benefits while preserving chocolate’s affordability, quality and cultural significance.
