While the world looked to the high-tech Rotterdam lab, Bernard Stuer was the heartbeat of the original Amsterdam brewery. For decades, he was the “Old Guard”—a man who witnessed the transition from the old “Haystack” traditions to the global scientific standard.He was more than a brewmaster; he was a stabilizer. He worked through the First World War and the transition to the second generation of the Heineken family. When he finally retired at age 73, he left the vats in the hands of his son, Carl, ensuring that the “Green Thread” remained a family affair both in the boardroom and the brewhouse.

Showing overlap within 1873–1912
Not alot of photo’s are available, but below is a very rare one:
One of those young men is likely Carl Stuer, who would eventually take over as Master Brewer in 1917, continuing the family legacy
Site Management: He managed a team of approximately 40 staff members, about half of whom were German skilled laborers known as “Wanderburschen”.
Daily Life: Stuer and his family lived directly on the brewery premises alongside the workers.
Quality Control: He was an unrivaled beer connoisseur; even later laboratory engineers at Heineken used Stuer’s palate as the ultimate benchmark for classifying brews
Keeper of the Haystack
When Stuer arrived in Amsterdam around 1873, the old brewery known as De Hooiberg—“The Haystack”—was no longer just a local operation. It was transforming into something far greater: the industrial core of what would become Heineken.
Stuer was not the man in the spotlight. He didn’t chase innovation like Feltmann, nor did he command the grand vision of Gerard. Instead, he became something arguably more essential:
the steady hand that made it all work.
He took charge of daily operations at De Hooiberg during a time of upheaval—when traditional brewing methods were being challenged, equipment modernized, and demand growing faster than ever before.
The Bridge Between Vision and Reality
If Gerard was the architect and Feltmann the scientist, Stuer was the builder.
- He ensured production didn’t falter while new techniques were introduced
- He managed workers, logistics, and consistency in an increasingly complex operation
- He kept Amsterdam’s brewery running while Rotterdam experimented and expanded
His role required not just skill, but trust. Gerard relied on him to hold the foundation steady, while Feltmann’s innovations—like improved fermentation techniques—were tested and refined elsewhere.
In many ways, Stuer was the link between tradition and progress.
A Quiet Partnership
Though history speaks more loudly of Feltmann and Gerard, Stuer worked in close alignment with both:
- With Gerard, he shared responsibility for maintaining the reputation of the brewery in Amsterdam
- With Feltmann, he implemented and upheld the practical side of brewing advancements
He may not have been the one inventing or branding—but he ensured those ideas could survive contact with reality.
Relationship with Wilhelm Feltmann
Stuer and Feltmann were the two halves of production:
- Geographic Split: By 1874, the labor was divided: Feltmann was responsible for the new Rotterdam brewery (which handled exports and the south), while Stuer handled Amsterdam (the west and north).
- Professional Contrast: Feltmann was often the face of “scientific” brewing and innovation, whereas Stuer was the “bedrock” of established brewing craft. This dynamic sometimes led to friction; later in life, Stuer reportedly had little patience for the “laboratory work” and academic approach introduced by the next generation (like Henry Heineken), preferring his seasoned instincts
An Epic Worth Remembering
So imagine Amsterdam in the late 19th century:
The canals thick with trade.
The brewery alive with heat, motion, and ambition.
Ideas flowing in from Rotterdam. Pressure rising from every side.
And there—amid the noise, the steam, the risk—stood Bernard Stuer.
Not chasing glory.
Not writing his name into legend.
But holding the line.
Because empires are not only built by dreamers and innovators—
they are kept alive by those who refuse to let them fall.
