Brewery Timmermans in Itterbeek used the occasion of Tour de Geuze (April 21) to launch a new product. Timmermans Oude Geuze was created with the help of master brewer Willem van Herreweghen. “Timmermans used to produce a lot of ??Oude Geuze,” van Herreweghen said. The name ‘Oude Geuze’ is legally protected and may only be used when the geuze is made from a combination of lambic that is at least three years old and aged in wooden barrels. “And there may be no sweetening agents added to the final product,” the brewer explained.
