Every beer on shelves today uses hops, so it’s easy to forget hops are a relatively recent addition to a drink that’s thousands of years old. Before hops took over, brewers across northern Europe used gruit, a mix of bittering and flavoring herbs, and for a while it wasn’t just a style choice, it was a legally enforced monopoly that functioned as a hidden beer tax.
What Gruit Actually Is
Gruit is a herb mixture used for bittering and flavoring beer before the widespread use of hops. The word comes from an area now spanning the Netherlands, Belgium, and northwestern Germany, and the earliest known reference to it dates from the late 10th century. Typical gruit blends included bog myrtle (sweet gale), yarrow, and other regional herbs, chosen for both bittering power and aromatic character, filling the same functional role hops fill in a modern beer.
The Medieval Monopoly on Beer
This is the part that actually makes gruit historically interesting rather than just a curiosity. In the 11th century, the Holy Roman Emperor Henry IV granted monopoly rights over gruit production and sale, called Grutgerechtigkeit, to specific local authorities. That effectively created a de facto tax on beer itself, since brewers within a diocese weren’t allowed to brew without buying the local authority’s gruit, and outside imports were restricted too.
The person or institution holding that gruit license could also control how much beer each local brewer was allowed to make, simply by controlling how much gruit they sold them. It’s a strange piece of medieval economic history hiding inside what looks, on the surface, like just an old-fashioned beer recipe.
Why Hops Eventually Won
Hops offered real practical advantages gruit herbs didn’t: natural preservative properties that helped beer travel and store longer, plus a more consistent, reliable bittering and aromatic profile. As hop cultivation spread and beer trade expanded across regions, brewers increasingly switched over, and the gruit monopoly system eventually lost its grip as the herb blend fell out of common use. By the time modern brewing science became standardized, hops had become the default bittering agent almost everywhere, and gruit slipped into the category of historical curiosity rather than mainstream practice.
What Gruit Actually Tastes Like
Modern gruit revivals (still made with actual hops seasoned with gruit-style herbs, since that’s now the colloquial use of the term) tend to taste earthier and more herbal than a typical beer, with less of the clean bitterness hops provide and more of a rustic, almost medicinal quality from bog myrtle and yarrow. It’s an acquired taste by modern standards, which is part of why it stayed a niche curiosity rather than making any kind of comeback the way sour beers or lambics eventually did.
Can You Still Find One
Genuine gruit is rare outside small experimental and historical-recreation breweries, since almost no commercial distribution exists for it. If you want the closest experience without hunting down a specialty brewery, look for beers marketed as historical recreations at homebrew festivals or from breweries specifically known for experimental and traditional styles; it’s not something you’ll find at a standard liquor store.

It is worth remembering gruit was not a fringe curiosity in its own time, it was the default across a huge stretch of medieval northern Europe for centuries before hops took over. The shift to hops was gradual rather than sudden, and for a long stretch both bittering methods coexisted regionally before hops eventually won out almost everywhere.
Some brewing historians argue the eventual dominance of hops was not purely about flavor or preservation either, it was partly about breaking free of the gruit monopoly system itself. Hops were not subject to the same licensing control, so brewers who switched gained a real economic independence on top of any taste benefit, a political dimension to an ingredient swap that gets flattened out of most short summaries of the topic.
FAQs
Did gruit beer contain any hops at all?
Historically, no, true gruit relied entirely on herbs like bog myrtle and yarrow for bittering and flavor. Today the term is used more loosely for hopped beers seasoned with gruit-style herbs.
Why was gruit controlled by a monopoly?
Local rulers, starting with a grant from Holy Roman Emperor Henry IV in the 11th century, controlled gruit production and sale, which let them tax and regulate beer production indirectly by controlling the supply of a required ingredient.
Can you buy gruit beer today?
It’s rare. Most modern breweries use hops exclusively, so genuine gruit-style beer is limited to small experimental, historical-recreation, or homebrew-focused producers.
