When Simon Violet died in 1891,his son Lambert took over. He continued his father’s work and completed the extension of the cellars. The new premises were inaugurated in 1892. The factory was then linked up to the rail network with a rail depot designed by Gustave Eiffel.

In 1910, the company had 750 employees on its books and was producing over 30 million litres of Byrrh per year.

Other cellars were built around the Pyrénées-Orientales, and numerous branches opened across France.

After Lambert’s death in 1914, his wife Marie was left to run the business. In 1920, Jacques and Simone, Lambert’s children, took over the reins of the family business and continued building new vats. At that point, the Thuir winery was the largest in the world and the holder of a number of records :

• The construction of 3 concrete vats, the largest of which held 680,000 litres. These vats were for blending and standardising wine.
• In 1934, an oak vat with a capacity of 4,205 hectolitres was built.
• The third and most impressive record is for the largest oak vat in the world. It holds 1,000,200 litres and was first filled in 1951, a record which stands to this day.
