A Boston-based biotech startup has launched a new brand that produces chocolate using lab-grown cocoa, aiming to combine precision science with traditional confectionery techniques. The company, Wunderhaus, operates under GALY Co. and officially entered the market this month with a range of milk and dark chocolate products designed for professional pastry chefs and cooks.

Wunderhaus produces its chocolate at facilities in Boston’s Seaport district and in Essex on the North Shore. The company applies advanced technology, including artificial intelligence, to monitor the quality of the cocoa cells during production. This approach allows for stringent control over factors such as temperature, fermentation time, and microbial concentrations, enabling the creation of varied flavor profiles from a single cell line.

“Because we control every variable, we can experiment with fermentation to produce dozens of unique flavors, even starting from the same cell base,” stated Anat Tewari, commercial lead at GALY. The company has significantly increased its production capacity by expanding into a former brewery building in Essex, tripling output capabilities. According to GALY’s leadership, weekly production can currently reach hundreds of kilograms, with plans to scale up to thousands in the coming year.

Currently, Wunderhaus chocolate contains up to 20% lab-grown GALY cocoa powder, supplemented with traditional cocoa powder and cocoa butter. The product blend varies across different chocolate varieties. The company acknowledges that the cost of producing lab-grown chocolate remains high at this stage, largely due to the small production scale. However, they anticipate costs will decrease as scaling efforts continue. GALY is presently working with conventional cocoa farms but has not disclosed future collaboration plans as production expands.

Not all industry professionals embrace lab-grown chocolate. Tom Rogan, co-owner of Goodnow Farms Chocolate in Sudbury, emphasizes the value of human relationships and traceability in creating quality chocolate. Rogan’s operation produces single-origin, small-batch chocolate by sourcing beans from specific farms, preserving unique characteristics. He highlights the cultural and environmental aspects that differentiate artisanal chocolate from mass-produced alternatives.

Nonetheless, Rogan acknowledges the potential role of lab-grown chocolate, especially given growing concerns about climate change and the vulnerability of cacao crops. “For large-scale manufacturers, having a sustainable alternative makes practical sense,” he said.

Early adopters such as Aaron Lhamon, executive chef at the French restaurant Troquet in Boston, have tested Wunderhaus chocolate with favorable results. Lhamon praised the product’s texture and performance in recipes, including his signature chocolate torte, and plans to make it the restaurant’s primary chocolate supplier. While current prices are higher than traditional sources—by about $8 per bag—he expressed optimism about future innovations, including the possibility of customizing chocolate recipes in the lab.

The emergence of lab-grown chocolate reflects ongoing efforts to address the challenges posed by climate change to cocoa cultivation, while meeting continuing global demand for chocolate products. As Rogan summed up, “There will always be a place for cacao,” underscoring that both traditional and scientific approaches are likely to coexist in the industry’s future.
