Jopen Adriaan is made as a lighter version of a gruit beer. Gruit is a medieval herbal mixture of which sweet gale is the most characteristic. Brewers used this gruit before hops were introduced. The beer contains 5% alcohol and is also brewed with herbs, but different ones than those used in Koyt. The herbs used in Adriaan contribute in the refreshing taste of Adriaan. The light taste of Adriaan can be compared with Wheat beers (Witbier) as those are made in Belgium and Holland.
