Duivels Bierr (also written Duivelsbier) is a historic beer from Halle (French: Hal in French) in the lambic family. Depending on the time period and producer, the production methods and characteristics of historic Duivels Bier would have varied. Around 1900 Duivels Bier was a spontaneously fermented beer with close similarities to lambic in both the characteristics of the final beer and in production methods. More recently Duivels Bier was a blend of lambic and top fermentation beer. Modern Duivels Bier is a top fermentation beer without lambic.
