"When I designed the first variable capacity tank in 1975 and the truncated tank in 1994,

I would never have imagined that my inventions would have been so influential in the forefront of the winemaking world."

Patrick LEJEUNE

After spending 15 years working in the petrol industry in Africa Pierre Lejeune founded a small mechanic and service company in Saint Magne de Castillon back in 1968.

His son Patrick joined him and together they developed a stainless steel expertise in the high demanding milk industry.

The first tanks that were launched specifically for the wine production appealed to the nearby Saint Emilion vinegrowers. Since then the firm developed into a major innovator in vats manufacturing and cellar installation advising, adapting to each specific winemaking process.

Nowadays the Bordeaux family-run company employs 46 people with a production floor base of 8 000 m2 and can manufacture tanks ranging from 300 to 10 000 litres.

The high quality and consistency of Lejeune advisory skills and its stainless steel products has resulted in the company continuing leading the way in design and development for the wine industry.
