In 1952, in order to place the modernisation of the brewery on the right commercial footing, much care was taken with the launch of Rochefort's two new beers. The refectory beer had been the basis for the development of the ‘Middel’ (also known as ‘Merveille’) which became the Rochefort 6. The 10, however, needed something else to elevate it: candy sugar, steeped in the wort in metal baskets, quite an innovation in those days. Furthermore, two malts were used in the brewing process: pils and caramel malt, as well as wheat starch, two varieties of hops and Rochefort’s own yeast. The result was the powerful Rochefort 10, a beer sure to warm your heart with its robust dose of alcohol.
