The House of Bols sits at the end of a cobbled lane near the Heineken Experience in Amsterdam, a modest doorway opening into a history that stretches back to 1575. Lucas Bols, the company's founder, began distilling liqueurs and genevers here in the late sixteenth century — three decades before gin, as we understand it, even existed. To visit Bols is to stand at the headwaters of everything we now call gin, and to be reminded how much we have forgotten.
Genever — jenever in Dutch, the word from which "gin" derives — is not gin. This is the first and most important thing to understand, and it is a distinction that the staff at the Bols distillery make with patient but firm insistence. Where gin is a neutral spirit flavoured with botanicals, genever is built on malt wine — a pot-distilled grain spirit with a rich, almost whisky-like character. The juniper and botanicals are layered on top of this base, creating something altogether more complex and weighty than its English descendant.
The Tasting Room
In the Bols tasting room, a wood-panelled chamber lined with bottles dating back decades, I sat with master distiller Piet van Leijenhorst and worked through four expressions: the Bols Genever (the standard bottling), Bols Barrel Aged, Bols Corenwyn (a malt-wine-heavy old style), and a limited annual release from 2024.
The standard Bols Genever is a revelation if you approach it expecting gin. The nose is malty and grainy, with juniper present but subordinate — more seasoning than main ingredient. On the palate, there's a richness that no London Dry can match: caramel, toasted bread, and a gentle sweetness that comes from the malt wine rather than from added sugar. The juniper provides a herbal counterpoint, and the finish is long and warming.
"People come in expecting gin," van Leijenhorst told me, swirling his Corenwyn with the proprietary air of a man who has spent thirty years refining a spirit that most of the world has forgotten. "They leave understanding that gin is genever's child — brilliant in its own right, but born from something older and richer."
A History in Bottles
The Bols archive, housed in a climate-controlled vault beneath the tasting room, contains bottles from every decade since the 1820s. Some are sealed and intact; others are empty vessels that once held spirits consumed by sailors, merchants, and the burghers of Amsterdam. The labels tell a story of shifting tastes — from the heavy, malt-rich genevers of the nineteenth century through the lighter styles that emerged as gin rose to dominance in the twentieth.
The company's historian, Marieke de Vries, guided me through the collection. "In the 1600s, genever was medicine," she explained, pointing to a reproduction of an early Bols ledger. "By the 1700s, it was everywhere — in taverns, on ships, in the homes of the wealthy. The English discovered it during the Anglo-Dutch wars and took the idea home. But they simplified it — removed the malt wine, used column-distilled spirit, and called it gin."
This simplification was, in one sense, genever's gift to the world — gin's clean, versatile character made it the foundation of modern cocktail culture. But it came at a cost. As gin boomed, genever declined. By the mid-twentieth century, it had been reduced to an old man's drink in the Netherlands, consumed in brown cafés and largely ignored by the international market.
The Revival
Today, genever is experiencing a modest renaissance. Craft bartenders in New York, London, and Berlin have rediscovered its richness and versatility, using it in cocktails that predate the gin-and-tonic era — the Improved Holland Gin Cocktail, the original Tom Collins (which was made with genever, not gin), and various punches that benefit from the spirit's malty depth.
Bols has responded with new expressions aimed at this market. Their Barrel Aged genever, finished in French oak for eighteen months, bridges the gap between genever and whisky in a way that appeals to brown spirits drinkers. The annual limited releases showcase unusual botanicals or experimental ageing techniques. And the standard bottling has been subtly reformulated to appeal to a broader palate without sacrificing authenticity.
But van Leijenhorst is realistic about genever's prospects. "We will never outsell gin," he said, as we finished the tasting and walked back through the quiet distillery. "But that is not the point. The point is that this spirit has a story worth telling, and a flavour worth preserving. As long as someone is still making real genever, the story continues."
Outside, the Amsterdam evening was settling over the canals, and the lights of the tourist district were beginning to glow. Somewhere in those streets, people were ordering gin and tonics by the thousand — gin that exists, in the end, because of what began in a warehouse like this one, four hundred and fifty years ago. It seemed worth remembering.
