JOZO Heritage – Pure Salt Since 1929

JOZO celebrates the rich history and natural origins of salt, providing pure, sustainable products that support health, well-being and everyday life.

A world of salt

The story, the grain, the taste

 

When the primordial waters of the Earth evaporated, salt remained. A mineral humankind has since extracted, refined, transformed and consumed. The importance of salt – both myth and fact – has been recounted in countless literary works and ancient manuscripts.

But this isn’t a history lesson. This is a celebration, of joy and creativity in what might appear to be the simple task of sprinkling, tossing or dabbing the world’s most ubiquitous mineral over, and into, that which we savour.

So, whether you’re a devoted food enthusiast or a casual cook, let yourself be inspired. Use, experiment, discover your artistry, and explore a world of salt.

Welcome to the world of JOZO Salt, where creativity and artistic inspiration are seasoned by our unwavering commitment to provide the finest salt for your table.

Just as our iconic salt house symbolises purity and tradition, our diverse range of colourful packs holds a trove of salt varieties to elevate your culinary journey.

Add a pinch of love to your meals with JOZO, and embrace the journey of taste, tradition and artistic expression that awaits you.

The Salt House

Discover the heritage of JOZO salt

  • Rooted in history: Our story begins in the town of Boekelo, with the pioneering of Royal Dutch Salt Industries (KNZ). Here, pure salt was once harvested through the early art of open-pan evaporation.
  • Evolution of excellence: In 1926, we embraced the future with the adoption of vacuum evaporation – a leap in efficiency and quality.
  • Shift to Hengelo: With the advent of the Twente-Rijn canal in the 1930s, our saltworks were repositioned to harness the power of waterways, setting a new standard in salt production and transportation.
  • Nordic expansion: By 1963, our horizons broadened to Denmark, bringing the purity of JOZO to Scandinavian tables.
  • The essence of nature: Even today, we delve into the earth’s ancient caverns in the Netherlands and Denmark to extract the purest salt, crystallised over millennia.

The Salt Houses

In the heart of Hengelo, tall black towers once rose above the landscape which were known locally as boortorens, or salt houses. These were the drilling rigs that first tapped into the Zechstein salt layers deep underground. For generations, they symbolised progress, precision and pride in Dutch salt craftsmanship.

These salt houses were where JOZO began. They marked the start of our journey – extracting pure brine, refining it with care and turning it into salt that generations have trusted. Though many of the original towers are gone, their legacy lives on. The silhouette of a boortoren still features proudly in the JOZO logo, connecting every pack to our salt cavern heritage.

It’s more than a symbol: it’s a promise. Of quality, of tradition,  and of doing things right.

From ancient seas to modern tables

Long before Europe had countries or cities, there was the Zechstein Sea – a vast inland ocean that covered parts of what we now know as the Netherlands and Denmark. When it dried up over 250 million years ago, it left behind something extraordinary: deep underground layers of pure salt.

At JOZO, we tap into these salt caverns, drawing up natural brine – pure salty water rich in minerals and untouched by pollution. This brine is then evaporated and crystallised carefully into the high-quality salt we use today. It’s a process that connects the precision of modern production with the raw beauty of geological history.

Where time, sea and stone become taste

Salt is born of patience — shaped by oceans, pressed by mountains, perfected by hands. For centuries, it has seasoned stories, preserved life, and revealed flavour. We continue that craft — transforming nature’s oldest ingredient into something quietly extraordinary.

The world’s salt sources are, in all likelihood, inexhaustible. Beneath our feet lie millions of tonnes of rock salt, and the oceans hold over four million cubic miles of it. And new salt is constantly being formed. Today, salt is extracted through three main methods: from the sea, by mining or through drilling. These give us sea salt, rock salt and vacuum salt.

Sea salt is harvested through natural evaporation in pools and pans—a method that has been used since antiquity in warm coastal regions.

Rock salt is mined from salt deposits beneath the earth’s surface, originally formed by long-vanished seas and sealed under layers of stone.

Vacuum salt, the purest of them all, is a product of modern engineering. A salt bed is accessed by drilling, then dissolved in water and evaporated to leave behind a highly refined, clean salt.
