Looking back, it is clear that company founder Gustav Paul Hildebrandt was a true pioneer when he began filling lemon juice in small, manageable glass bottles. An idea that proved to form the basis for an unbelievably successful company history.

Birth of a success story.

Dresden native Gustav Paul Hildebrandt was an ambitious engineer with a passion for designing and building machines. From 1935 onwards, he and his wife Dorothea also ran a well-known delicatessen in Dresden called “Aufs Brot.” One day, when a customer asked for a small amount of lemon juice, Gustav Paul Hildebrandt began filling it in small bottles. At the time, it was standard practice to sell fresh lemon juice in one-liter bottles, as smaller amounts geared towards households were not yet available. This was the genesis of a simple yet highly successful idea: selling lemon juice in small 100 ml bottles under the family name to lovers of fine cuisine.

In the years that followed, what began with a simple idea in a small store in Dresden grew into an amazing success story that made waves all over the globe.

Innovation and inventiveness.

In 1950, Gustav Paul Hildebrandt invented and built an automatic filling line that took over the chore of filling the glass bottles by hand. In the mid-1950s, the innovative inventor also developed a blow-molding machine for manufacturing plastic bottles, thereby providing a viable alternative to glass bottles, which were notably sensitive to frost and transport. Ever since then, the bottle has been a little smaller, yellow in color, and with that typical SICILIA form.

But the real magic is inside the bottle. In its purest form, the juice of lemons and limes is very bitter indeed. However, when you squeeze a natural lemon or lime, they give off a wonderful aroma of fresh juice and fine lemon oil. The problem is that the precious citrus fruit oil is found in its peel, which is lost almost entirely when the fruit is squeezed. Gustav Paul Hildebrandt solved this problem in 1956 when he developed a special insert that is still used in the neck of SICILIA bottles, allowing the wonderfully fresh aroma of citrus fruits to be retained. This patented capsule serves as an aroma deposit for the valuable citrus oil, which automatically accompanies every squirt of juice.

In 1956, the family established the company headquarters in Berlin (Germany), which to this day supplies only the German market. By 1974, two further sites had been established in Sicily (Italy) and Sulgen (Switzerland), both focusing on the international orientation of the brand.

New products were created in the years that followed. In addition to the classic favorite “SIZILIA Express-Zitrone” lemon juice, aromatic lime juice products and organic seasonings established themselves as further highlights in the SICILIA product range. Since then, a great many recipes and packaging units have graced the shelves of retailers under the SICILIA (or, in Germany, SIZILIA) brand.

The success of the SICILIA product range in the US market prompted the family to expand the company even further in 1988, setting up companies in Sulgen (Switzerland) and New Jersey (USA).

For the family’s subsequent generations, too, investments in the future of the company are very much driven by technical progress and by the innovative spirit kindled by company founder Gustav Paul Hildebrandt. A further technological milestone for the sector was set in 1995, when the first ever fully automated filling line did away with manual juice bottling.

Today, with the family’s third generation now at the helm, the company's innovative spirit is as healthy as ever. Modernization and extension work is being carried out at all locations, while extensive certification processes are being finalized, production relocated, and representative offices established in foreign markets. The move into the Russian market and a complete relaunch of the brand are also a clear indication of the progressive and dynamic development of the SICILIA Group, which is set to remain alive and well for generations to come.
