Oerbier, brewed in Esen by De Dolle Brouwers, is dark due to the mixture of different types of malt and hours of cooking time. Only 'Golding' bubble hop from Poperinge is used and all our beers are bottled with secondary fermentation. The name refers to the originality and purity of the beer. The specific gravity of the wort is 1078, the alcohol percentage 9%. Oerbier has a slightly fresh acidity due to the yeast and lactic acid bacteria.
The best-before date is imposed by law: one year after bottling, this is also mentioned on the capsule. The beer will experience a slight taste evolution and will become vinous. Samples of the first brew, which are still perfectly drinkable, are kept in the brewery.
