Charles Caulier was a miner and founded the House Caulier in 1933. He first started with the distribution of beer. In 1942, Caulier was producing a beer of intense flavours from natural ingredients.
In 1994, the Caulier Brewery built its own brewery in the little town Peruwelz. In the beginning of May 1995 the first locally brewed beer has been presented to the public.
The Vieille Bon Secours Ale is rumored to be the most expensive beer in the world. This rumor seems to stem from a restaurant which found a 12 liter Vieille Bon Secours bottle in the cellar, stored for more than 10 years. That bottle is set to have a value of £700 (around €825, $dollar;1,075) which at the time probably was one of the worlds most expensive beers. Only a few bars and restaurants have the Vieille Bon Secours 12 liter in stock. One pint (0.5l) costs around $50.
The taste of the beer has been described as a complex taste with citric, toffee and caramel flavours with an undertone of liquorice and aniseed.
The Vieille Bon Secours can also be purchased in smaller bottles, and there the price seems to be more moderate, so whether the Vieille Bon Secours really is the worlds most expensive beer is uncertain.
The Vieille Bon Secours has a rival for the title as the world's most expensive beer. In 2008 Carlsberg released the limited edition Jakobsen Vintage No. 1 which earned the title "The world's most expensive beer" at the time.
