It’s a crisp October evening in Portland, Oregon, and the air smells of woodsmoke and hops. A crowd gathers outside a repurposed warehouse, clutching pints of something golden and effervescent. The chatter isn’t about the latest IPA or a trendy sour ale—it’s about IJsheiligen, a Dutch tradition that, until last year, barely registered on America’s cultural radar. Now, it’s everywhere: pop-up beer gardens in Brooklyn, rooftop tastings in Denver, even a viral TikTok challenge where users attempt to pronounce the word correctly (spoiler: most fail).
This isn’t just another imported fad. IJsheiligen—a celebration of the season’s first ijsbokbier (ice bock beer), traditionally brewed when temperatures drop below freezing—has become a full-blown phenomenon. But how did a niche Dutch custom, rooted in 16th-century brewing techniques, captivate American millennials and Gen Z? The answer lies in its unexpected resonance with modern values: authenticity, community, and a yearning for connection in an increasingly digital world.

To understand IJsheiligen’s sudden appeal, we must first trace its origins. The tradition didn’t begin as a celebration but as a practical solution to a brewing challenge—and a stroke of serendipity that would shape Dutch culture for centuries.
Rewind to the Netherlands in the 1500s. Brewers storing beer in unheated barns noticed something peculiar: when winter’s first frost arrived, the liquid would freeze, leaving behind a concentrated, high-alcohol elixir—ijsbokbier. This wasn’t merely a happy accident; it was a revelation. The beer was richer, smoother, and packed a warmth that made it ideal for cold months. Over time, the tradition evolved into IJsheiligen (“ice saints”), a tribute to the patron saints of brewers and the fleeting magic of the first frost.
In the Netherlands, IJsheiligen remains a low-key affair: limited batches of ijsbokbier, cozy gatherings in bruin cafés, and quiet toasts to the season. But in America, it has morphed into something far larger—a cultural moment that taps into deeper cravings. To understand why, we need to examine the forces propelling its rise.
The tradition’s American boom isn’t accidental. It’s the result of a perfect alignment between IJsheiligen’s inherent qualities and the zeitgeist of a generation. Here’s how it checks every box for modern audiences:
This alignment with modern values explains why IJsheiligen isn’t just surviving in America—it’s thriving. But its success also stems from how American breweries have reimagined the tradition, blending Dutch heritage with local creativity.
American breweries aren’t merely replicating IJsheiligen; they’re expanding its possibilities. Some lean into spectacle, while others prioritize authenticity. The results are as diverse as the country itself.
In Austin, Texas, Jester King Brewery merges Dutch tradition with Texan flair. Their annual IJsheiligen event features a bourbon-barrel-aged ijsbokbier, live music, and farm-to-table dinners. The fusion of local ingredients and historical methods creates something entirely new—proof that traditions can evolve without losing their essence.
Meanwhile, Other Half Brewing in Brooklyn transforms IJsheiligen into a multisensory experience. Their “frost fair” includes ice sculptures, historical workshops, and even a pop-up market. The goal isn’t just to sell beer; it’s to immerse attendees in the culture behind it. By treating IJsheiligen as a cultural event rather than a drinking holiday, they’ve elevated it into something more meaningful.
Not all breweries opt for grandeur. Russian River Brewing Company in California takes a minimalist approach, releasing a single batch of traditionally brewed ijsbokbier in their taproom. Their focus on craftsmanship over gimmicks resonates with purists who value the beer’s integrity. This diversity of approaches ensures that IJsheiligen remains dynamic, appealing to a wide range of tastes and preferences.
Yet, the tradition’s most surprising champions might be the youngest drinkers—Gen Z and millennials—who’ve embraced it with unparalleled enthusiasm. Their reasons reveal much about what this generation values.
For younger Americans, IJsheiligen isn’t just a trend; it’s a cultural touchstone. Its appeal lies in how it intersects with their priorities: social media, climate consciousness, and a desire for experiences that feel both personal and shareable. Let’s break down why it’s resonating so deeply.
On TikTok and Instagram, IJsheiligen is a content creator’s dream. The beer’s golden hue and unique glassware make it inherently photogenic, while the tradition’s quirks—like its unpronounceable name—provide built-in engagement hooks. Videos of people attempting (and often failing) to say “IJsheiligen” have racked up millions of views, turning the tradition into a viral sensation.
But the appeal goes beyond aesthetics. IJsheiligen offers something rare in the digital age: a sense of exclusivity. For a generation that thrives on being “in the know,” discovering and sharing a niche tradition like this feels like joining a secret club. The FOMO factor is real—attending an IJsheiligen event isn’t just about the beer; it’s about being part of a cultural moment.
Perhaps the most unexpected draw is IJsheiligen’s link to climate. The tradition’s reliance on the first frost makes it a poignant reminder of nature’s fragility. For a generation raised on climate anxiety, it offers a way to engage with environmental themes without feeling powerless. It’s a celebration of resilience, both in nature and in human ingenuity.
Some breweries are leaning into this connection. Allagash Brewing Company in Maine partnered with environmental groups to host an IJsheiligen event focused on climate action. Proceeds supported conservation efforts, and the event featured talks from scientists and activists. This blend of celebration and advocacy resonates deeply with younger audiences, who want their leisure activities to align with their values.
Yet, IJsheiligen’s appeal isn’t just about serious themes. American breweries have also embraced its playful side, creating events that push the boundaries of what a “beer holiday” can be.
If you think IJsheiligen is just about drinking beer, think again. American breweries and event organizers are redefining the tradition with creativity and whimsy. Here are some of the most inventive takes on IJsheiligen across the country:
These events prove that IJsheiligen is more than a drinking holiday; it’s a canvas for creativity. But as the tradition grows, it also faces challenges—particularly around authenticity and cultural respect.
With any cultural phenomenon, growth comes with risks. As IJsheiligen gains popularity in the U.S., it’s grappling with questions about commercialization, authenticity, and cultural appropriation. These tensions aren’t unique to this tradition, but they’re worth examining as it evolves.
The biggest threat to IJsheiligen’s integrity is its own success. As demand grows, some breweries are cutting corners to meet it. Traditional ijsbokbier is brewed by naturally freezing beer, a process that requires patience and precision. But some American breweries are using artificial freezing techniques to speed up production, diluting the beer’s authenticity.
For purists, this is sacrilege. IJsheiligen isn’t just about the end product; it’s about the process—the connection to nature, the craftsmanship, the history. When breweries prioritize convenience over tradition, they risk stripping the celebration of its soul.
Then there’s the question of cultural respect. IJsheiligen is a Dutch tradition, and as it gains traction in the U.S., some worry it’s being stripped of its cultural context. Are American breweries paying homage, or are they exploiting a tradition for profit?
This debate isn’t easily resolved. On one hand, cultural exchange has always been a part of human history, and traditions often evolve as they cross borders. On the other, there’s a fine line between appreciation and appropriation. The key lies in how breweries engage with the tradition: Are they educating their audiences about its origins? Are they collaborating with Dutch brewers to ensure respect for the craft? Or are they treating it as a trendy gimmick?
These questions don’t have simple answers, but they’re essential to consider as IJsheiligen continues to grow. Its future in America will depend on how thoughtfully it’s embraced—and whether its new champions can balance innovation with respect for its roots.
So, where does IJsheiligen go from here? Will it fade like so many other trends, or will it carve out a lasting place in American culture?
The answer likely lies in its ability to adapt without losing its essence. IJsheiligen has already proven it has staying power. It’s not just a flash in the pan; it’s a tradition with depth, history, and a unique connection to climate and community. But as it grows, it will inevitably change. The challenge is ensuring that change is thoughtful and respectful.
One thing is certain: IJsheiligen has tapped into something primal. It’s a celebration of nature, of community, of the simple joy of gathering with friends over a shared experience. In a world that often feels fragmented, that’s a powerful draw. Whether it’s the beer, the history, or the sense of belonging, IJsheiligen has struck a chord—and it’s not letting go anytime soon.

At its core, IJsheiligen is about more than beer. It’s a bridge between past and present, a reminder that traditions can evolve without losing their meaning. It’s a celebration of resilience—of nature, of craftsmanship, of community. And in a time of uncertainty, it offers something rare: a reason to gather, reflect, and raise a glass to the unexpected joys of connection.
So, the next time you see IJsheiligen trending on social media or hear about a local brewery hosting an event, don’t just scroll past. Take a moment to appreciate the story behind it. Better yet, grab a pint of ijsbokbier, gather your friends, and toast to the traditions that bring us together—even the ones we never saw coming.
After all, in a world that’s always moving forward, sometimes the best way to find your footing is to look back.
IJsheiligen is a Dutch tradition celebrating the season’s first ijsbokbier, a strong beer brewed when temperatures drop below freezing. It honors the patron saints of brewers and the magic of the first frost, blending history, climate, and community into a single celebration.
Its rise is driven by a mix of nostalgia, novelty, and social media appeal. The tradition offers authenticity, a connection to nature, and a sense of exclusivity—all of which resonate with younger generations. Its unpronounceable name and photogenic qualities also make it a hit on platforms like TikTok and Instagram.
It’s pronounced “ICE-high-luh-gen.” The “IJ” sounds like the English “eye,” and “heiligen” rhymes with “high-luh-gen.” The pronunciation challenge has become part of its charm, sparking viral videos and friendly competitions.
Some are, but others are taking shortcuts. Traditional ijsbokbier is brewed by naturally freezing beer, a process that can take weeks. Some American breweries use artificial freezing to speed up production, which purists argue dilutes the beer’s authenticity.
From ice lounges to dog sledding adventures, American breweries are pushing the boundaries of the tradition. One standout is a silent disco in Brooklyn, where the music changes based on which beer you’re drinking—a playful twist on the Dutch original.
It’s too early to say for sure, but the tradition has depth and staying power. If it continues to evolve thoughtfully—balancing innovation with respect for its roots—it could become a lasting part of American culture. Its connection to climate and community gives it a relevance that extends beyond mere novelty.
