Grote familieclash over winst uit alcoholvrij bier en andere beleggingen
Amsterdam, maandag, 1 juni 2026.
De rijke Kloosterboer-familie staat tegenover Convent Capital in vier rechtszaken in Amsterdam. Het gaat om de verdeling van winsten uit gezamenlijke beleggingen. Een daarvan is het alcoholvrije biermerk Maeve. De familie wil eerst volledig inzicht in alle geldstromen. Pas dan zou ze akkoord gaan met een uitkoop van 150 miljoen euro. Volgens bronnen zouden twee oprichters van Convent Capital zelf 188 miljoen euro per persoon hebben weggeleid. Dit maakt de sfeer extreem gespannen. De uitslag van de rechtszaken kan grote gevolgen hebben voor toekomstige samenwerkingen en beleggingsstrategieën.
legal battle over investment profits
The wealthy Kloosterboer family from North Holland is involved in four separate lawsuits against the Amsterdam-based investment firm Convent Capital. The disputes center on profit distribution from joint investments made after the family sold their previous business for €1 billion [QuoteNet]. Key assets under contention include stakes in lifestyle brands such as the alcohol-free beverage sector. Both parties have presented strong legal arguments regarding financial transparency and ownership rights [QuoteNet].
conflict centers on financial transparency
At the heart of the dispute is the Kloosterboer family’s demand for full disclosure of financial flows before accepting a proposed buyout sum of €150 million. They argue that without complete insight, fair assessment is impossible [QuoteNet]. The tension intensified due to allegations that Convent Capital co-founders Maarten Meijnen and Dirk Hoorn diverted approximately €188 million each into personal holding companies [QuoteNet]. This claim remains legally contested but has significantly strained negotiations.
investment in non-alcoholic beverages questioned
One contested asset is linked to the growing alcohol-free beer market, specifically referencing the Maeve brand. While the name Maeve overlaps with a failed aerospace venture, the beverage investment stands apart [QuoteNet]. Alcohol-free beer saw its market share rise from 7.6% to 8.9% in 2025, even as traditional pilsener sales dropped by 4.7% [QuoteNet]. This shift reflects broader consumer trends that both parties sought to capitalize on through shared ventures [QuoteNet].
market shifts favor new beverage models
Despite challenges in the brewing industry—including the bankruptcy of Eindhoven-based Lighttown Brewers—demand for alcohol-free options continues rising [QuoteNet]. Industry analysts note that new business models focused on zero-alcohol packages and event catering are emerging [QuoteNet]. With only 23% of Dutch households currently investing despite having sufficient capital, large private fortunes like the Kloosterboers’ play an outsized role in shaping niche markets such as premium non-alcoholic drinks [QuoteNet].
broader economic implications emerge
The outcome of these Amsterdam court cases may influence future collaboration among elite investor circles in the Netherlands. As European regulators consider tighter controls via a potential ‘Made in Europe’ policy framework, domestic investment clarity becomes more critical [QuoteNet]. Legal experts suggest that unresolved fund diversions could complicate compliance with upcoming EU subsidy rules if firms cannot demonstrate transparent ownership structures [QuoteNet][FD].
calculating recent market changes
The decline in pilsener market share was calculated as follows: starting from 76.8% and ending at 74.6%. The change represents -2.865, resulting in a decrease of approximately -2.86% [QuoteNet]. For alcohol-free beer, growth was determined by computing 17.105, showing a 17.11% relative increase in market share during 2025 [QuoteNet]. These figures underscore shifting consumption habits affecting investor returns.
