Gruit, a mixture of herbs and spices used to balance the malt sweetness, flavour, and aromatize beer before the use of hops in the Middle Ages (as well as a means of taxing beer production) is no longer popular. And yet great beer can be brewed with it.
This recipe presents a golden coloured beer, with malt sweetness and a great harmony with the aromas and flavours brought by the added Gruit. This beer is refreshing and should be served fresh.
