Forgotten Dutch Bean Varieties Are Making a Comeback — From Gene Banks to Supermarket Shelves
Wageningen, Monday, 8 June 2026.
Wageningen University is partnering with food brand HAK to bring centuries-old Dutch bean varieties back into production, while nearly 100 schools in Groningen are growing them in gardens — proving heritage crops have a real future.
An Agritech Story Rooted in History
This is fundamentally an agritech and food innovation story — one that sits at the intersection of agricultural biodiversity, sustainable food systems, and consumer-driven demand for traceable, locally rooted produce. The driving force behind this revival is Wageningen University & Research (WUR), one of the world’s leading institutions in the life sciences and agricultural research [1]. The initiative centers on so-called erfgoedrassen — a Dutch term for heritage cultivars, traditional crop varieties that were once regionally adapted and widely grown across the Netherlands, but have largely disappeared from commercial agriculture over the past century due to the industrialization and standardization of food production [1].
What Was Lost — and Why It Matters
Until roughly a century ago, virtually every region of the Netherlands cultivated its own distinctive crop varieties, each one shaped over generations to suit local soils, climates, and culinary traditions [1]. The modernization of commercial agriculture, driven by the push for higher yields and uniform produce, systematically displaced these regional varieties from the landscape [1]. The result was a dramatic narrowing of agricultural biodiversity — a process that has left food systems globally more vulnerable to disease, climate stress, and supply chain shocks [GPT]. The specific bean varieties at the center of this Dutch revival include the Friese Woudboon, the Noord-Hollandse Krombek, and the Wieringer boon — all locally adapted heritage varieties that WUR and its partners are now testing to assess how they perform under contemporary Dutch growing conditions [1].
From Frozen Storage to Farmers’ Fields: How the Process Works
The mechanism behind this revival is relatively straightforward in concept, though significant in execution. Heritage seed varieties are held in gene banks — scientific repositories that preserve plant genetic material, often in carefully controlled cold storage — where they have remained largely dormant from a commercial perspective [GPT]. WUR is now acting as a bridge between these gene bank collections and real-world food production [1]. In a recent trial that began in 2026, Dutch food producer HAK — a well-known Dutch brand widely recognized for its canned and jarred vegetables and legumes — launched a practical test growing forgotten Dutch legumes, specifically the Friese Woudboon, the Noord-Hollandse Krombek, and the Wieringer boon, to evaluate how these historically local varieties perform in today’s Dutch agricultural environment [1]. The trials are explicitly designed to determine whether these heritage bean varieties can realistically be reintegrated into the modern food chain on a structural basis, rather than remaining curiosities for collectors and enthusiasts [1].
Classrooms as Test Beds: The Groningen School Garden Initiative
Alongside the commercial trials being conducted with HAK, a parallel educational initiative launched in the spring of 2026 is bringing heritage beans directly into school gardens across Groningen, a province in the northern Netherlands [1]. The project, called ‘Red de Groninger boon’ — meaning ‘Save the Groningen Bean’ — was initiated by Sanne Meijer, and by June 2026, nearly 100 primary schools in the Groningen region were participating [1]. In their school gardens, pupils are growing rare historical bean varieties sourced from gene banks, including the Hinrichs Reuzen, the Groninger Strogele, and the Oldambtster Witte [1]. The educational objectives of the project extend well beyond horticulture: the initiative is designed to teach children about regional history, biodiversity, sustainability, and healthy nutrition simultaneously [1]. Photographs documenting the school gardens were taken by Sanne Meijer herself in June 2026, capturing the scale of participation across the province [1].
Benefits of the Innovation: Resilience, Nutrition, and Cultural Identity
The benefits of reintroducing heritage bean varieties into commercial and educational cultivation operate on several levels simultaneously. From an agritech perspective, locally adapted heritage varieties carry genetic traits — including potential drought tolerance and disease resistance — that have been diluted or entirely lost in modern monoculture farming [GPT]. These traits are increasingly valuable as climate variability places greater stress on conventional crop systems [GPT]. From a food and nutritional standpoint, heritage varieties frequently offer distinct flavor profiles and nutritional characteristics that differentiate them from their industrially standardized counterparts, making them attractive to consumers seeking authenticity and provenance [GPT]. Commercially, the HAK trials represent a significant signal: a mainstream food producer is willing to invest in testing whether these varieties can be scaled beyond niche markets [1]. HAK’s involvement is particularly notable given the brand’s reach within Dutch supermarkets [alert! ‘The source confirms HAK is testing heritage bean varieties but does not specify HAK distribution channels or retail partners by name’], suggesting that a successful trial outcome could place heritage beans on mainstream supermarket shelves rather than confining them to specialty food stores [1].
A Movement Leaving the Margins
What distinguishes the current moment from earlier, smaller-scale efforts to preserve heritage varieties is the convergence of institutional support, commercial interest, and grassroots educational engagement happening simultaneously in 2026 [1]. For years, erfgoedrassen remained the province of dedicated collectors, seed-saving enthusiasts, and a small number of specialist growers [1]. The combination of WUR’s scientific infrastructure, HAK’s market reach, and Sanne Meijer’s school-based movement in Groningen represents a more systemic attempt to embed heritage crops back into both the food economy and public consciousness [1]. The ultimate goal, as stated by the parties involved, is to investigate whether historical bean varieties can once again play a structural role within the modern food chain and in everyday consumption — a goal that, as of June 2026, remains in the testing and evaluation phase rather than full commercial deployment [1].
