Zurich-based chocolate maker Barry Callebaut will invest €250 million over several years to upgrade and future-proof its Wieze factory in Belgium, the world’s largest chocolate production site.

The news comes as the group aims to double down on operational efficiency and customer reliability amid ongoing volatility in global cocoa markets.

The investment forms part of a broader capital programme aimed at strengthening Barry Callebaut’s European manufacturing backbone, with a further €125 million earmarked for its Halle facility, also in Belgium.

The Wieze site plays a central role in supplying industrial food manufacturers, professional users and global consumer brands across Europe and beyond.

The upgrades are designed to modernise production lines, improve food safety and quality standards, and enhance on-site logistics, including the construction of a ring road to streamline traffic flows and reduce environmental and safety risks.

Barry Callebaut says part of the spending falls under its previously announced 'BC Next Level' programme, which focuses on operational excellence, cost discipline and service levels, while the remainder represents routine capital expenditure.

The move comes as food manufacturers face sustained pressure from historically high cocoa prices, tighter margins and increased scrutiny around supply chain resilience and sustainability.

By investing heavily in its largest facility, Barry Callebaut is signalling a long-term commitment to scale, efficiency and reliability for customers that rely on a consistent chocolate and cocoa supply.

“Wieze remains a cornerstone of our global production network,” said Wim Debedts, managing director for the group's Benelux and Nordics regions. “These investments reinforce our ability to deliver quality, value and service to customers worldwide.”

Plant manager Filip Hermans said the masterplan would also improve working conditions and safety for employees, while ensuring the site remains fit for purpose in the years ahead.

Barry Callebaut operates more than 60 production facilities globally and reported sales of CHF 14.8 billion in its 2024/25 financial year.

The group supplies chocolate, cocoa and non-cocoa solutions to large food manufacturers as well as artisanal and professional customers, with Belgium remaining a hub for its European operations.
