Oerbier is a dark beer by De Dolle Brouwers. It is a top fermentation beer with a very rich and full flavor, which almost tends towards that of a quadruple beer. This beer gets its unique dark color and rich flavor by the combination of different malts and by boiling it for many hours, much longer than for other dark beers. It has an alcohol content of 9.0%.
Oerbier was the very first beer by De Dolle Brouwers (The Crazy Brewers) and it is still their best known beer. Despite their worldwide success, the brewery still brews in small batches, preferring quality over quantity. Besides this beer, they also brew once per year one Belgium’s only Easter beers, called Boskeun.
