The Castel Group, founded in 1949 by French entrepreneur Pierre Castel and his siblings in Bordeaux, France, is a privately held multinational beverage conglomerate with annual revenues exceeding €5 billion and employing around 40,000 employees. Initially the company focused on wine trading and production, making it the world’s third-largest wine producer. The company expanded into beer and soft drinks, particularly in Africa, where it operates over 85 breweries and 120 soft drink plants across 23 countries.
Castel dominates the African beer market (second-largest producer excluding South Africa) through subsidiaries like BGI, producing brands such as Flag and Castel Beer, and holds partnerships with giants like Diageo and Coca-Cola.
Pierre Castel, now 98, built the empire starting with wine exports to French-speaking West Africa in the 1960s, evolving it into a family-controlled powerhouse amid recent diversification, including the January 2025 acquisition of an 80.4% stake in Guinness Ghana Breweries for $81 million.
Breakdown of Leadership Shifts
Gregory Clerc l, the 40-year-old CEO, appointed in October 2023 as the first non-family executive to lead the group, is consolidating his influence over operations, particularly in Africa. Clerc, a former tax lawyer who represented Pierre Castel in a high-profile Swiss tax dispute, has overseen strategic moves like the Guinness Ghana deal, signaling his growing authority.
In a recent escalation, Alain Castel, nephew of the founder and a key family figure, was dismissed from a major holding company. This move, reported on December 8, 2025, removes Alain from oversight of critical beverage and agricultural subsidiaries.
Circumstances Leading to Departures
The shifts stem from intensifying succession tensions in the secretive, family-dominated group as Pierre Castel, at 98, steps back further. Clerc’s appointment in 2023 was backed by Pierre to professionalize management and resolve past disputes, including the Swiss tax case where Castel faced a $416 million bill in 2022 (later mitigated).
However, this has irked heirs and relatives, who view Clerc—an outsider with deep legal ties to the founder, as overreaching. Alain’s dismissal, described as “adding fuel to the fire,” follows earlier reshuffles where Clerc sidelined “old guard” family influences to streamline decision-making amid regulatory hurdles (e.g., delays in Central African mill acquisitions). Family frustrations peaked after Clerc’s consolidation of control over African beer operations, seen as prioritizing efficiency over familial input.
Future Implications
These changes could deepen rifts among Castel’s heirs, potentially leading to legal challenges or splintered governance, especially as Pierre’s health and the group’s €5 billion empire hang in balance—echoing past family disputes over dividends and control. On the positive side, Clerc’s outsider perspective may accelerate growth, building on 2025’s Guinness milestone and enabling bolder expansions in high-potential African markets. However, prolonged infighting risks operational disruptions in volatile regions, investor unease, or talent flight. Analysts see it as a pivotal test of the group’s transition to non-familial leadership, with success hinging on reconciling entrepreneurial legacy with modern corporate agility.
