Jenlain is a family story, 5 generations of enthusiasts have followed one another.  

In 1900, Léon Duyck set up his first brewery in Flanders at Zeggerscapel. This brewery will be destroyed during the Second World War.

In 1922, Félix Duyck, Léon Duyck's son, set up his farm brewery in Jenlain and created the recipe for amber aging beer.

In 1949, Félix Duyck and his son Robert came up with the idea of putting beer in Champagne-type bottles with a cork stopper and a wire that held the stopper. Thanks to this great first, the Duyck brewery stands out from the rest and develops.

At the end of the 1960s, this beer for cellaring began to gain recognition but had no name or label. In neighboring villages, it is nicknamed "old beer".

In 1968, Robert Duyck decided to name it to facilitate commercial development and therefore called it after the name of the village where the brewery is located: JENLAIN. The end of the 1960s was marked by the arrival of large-scale distribution. Jenlain takes the opportunity to be gradually distributed throughout France.  It is one of the first beers to appear in the beer cellars of major distributors.

​

In the 1980s, Jenlain negotiated directly with supermarkets, and no longer via distributors, and thus established itself throughout France with Jenlain Ambrée 75cl.

​

In 1990, Robert Duyck's son, Raymond, took over the reins of the brewery, which is almost a single product. Jenlain Ambrée then represents 90% of production. Raymond Duyck decides to expand the range. Over the years, the Jenlain Blonde, the Jenlain Gold or the Dark have made their appearance.

Others have disappeared like the Fraîche de l'Aunelle, the flavored J beer or the Sebourg. Since then, the Brewery has continued to develop and innovate.

​

In 2013, Mathieu Duyck joined his father and participated in the international development of the Brewery. Jenlain is a small traditional brewery with a worldwide reputation today.
