I’m very interested in Gruits, or beers that are brewed with herbs that aren’t hops. Hops are actually a rather recent addition to beer as an ingredient. (Please note: the following history lesson is mostly hearsay.) You may have heard of the Reinheitsgebot or German/Bavarian Beer Purity law limiting the ingredients of beer to water, barley, and hops (yeast was not yet understood as an ingredient).
Before the widespread acceptance of this ridiculous law, beer was brewed with a lot of different herbs. There was a system of Gruit houses that were controlled by the Catholic Church, they were a monopoly that controlled the distribution of herb mixtures for making ale (called Gruit) and the Beer Purity law was partly a Lutheran rebellion against the Catholic Gruit. Gruit was a proprietary mixture of herbs but common herbs in the mixture were Yarrow, Sweet Gale (aka Bog Myrtle), Marsh (or Wild) Rosemary, and Mugwort. Though other herbs such as Heather, Juniper, and Sage were also common.
In today’s terminology Gruit is a sort of generic term for a beer made without hops. I’ve been interested in what sort of brews I could make with the variety of herbs and plants that are growing in my yard.
