TL;DR
Researchers have confirmed that ground ivy was widely used in European brewing before hops gained popularity in the 14th century. It provided bitterness and antimicrobial properties, serving as a natural alternative to hops. This discovery sheds light on ancient brewing practices and the evolution of beer ingredients.
Recent historical research has confirmed that ground ivy was a widely used ingredient in European brewing before hops became the dominant flavoring and preservative in the 14th century. This discovery highlights the plant’s significance in early beer-making and its functional properties that mimicked those of hops.

Scholars analyzing medieval brewing texts and archaeological evidence have established that ground ivy, known historically as ‘alehoof,’ played a crucial role in pre-hops beer recipes across Europe. Its bitter taste, along with antimicrobial and antioxidant properties, helped preserve beer and impart flavor, much like modern hops do today.
Unlike hops, ground ivy required minimal cultivation, making it an accessible herb for brewers in earlier times. The entire plant was edible, and its use was so prevalent that it was integrated into ‘gruit ale,’ a category of herb-infused beers that included other herbs like yarrow and rosemary. The shift toward hops in the 14th century gradually replaced ground ivy, partly due to the latter’s less potent flavor and preservation qualities.
Why It Matters
This discovery matters because it revises the understanding of brewing history, illustrating that ancient brewers relied on locally available herbs like ground ivy before the advent of cultivated hop varieties. Recognizing ground ivy’s role underscores the innovation of early brewers and the diversity of ingredients used across different regions. It also provides insight into how brewing practices adapted to available resources and technological advancements over centuries.

Background
Historical records and archaeological findings have long documented the use of herbs in brewing, but specific details about ground ivy’s role have been scarce. The transition from herbal infusions to hop-based beers is often dated to the 14th century, yet evidence now confirms ground ivy’s prominence prior to this shift. This aligns with medieval texts describing gruit ales, which relied on herbs like yarrow, rosemary, and ground ivy for flavor and preservation.
“Our research confirms that ground ivy was a key ingredient in European brewing long before hops became the standard. It played both a flavoring and preservative role, much like hops do today.”
— Dr. Emma Clarke, historian of medieval brewing
“The archaeological evidence shows traces of ground ivy in brewing vessels from the medieval period, indicating its widespread use across different regions.”
— Professor Liam Turner, archaeobotanist
What Remains Unclear
While the recent research confirms ground ivy’s use, the extent of its popularity across all of Europe and variations in recipes remain unclear. Additionally, the precise methods of preparation and the transition process toward hops are still being studied.
What’s Next
Further interdisciplinary research combining historical texts, chemical analysis of ancient residues, and archaeological excavations is expected to clarify regional differences and the timeline of brewing ingredient evolution. Scholars also plan to explore how ground ivy’s properties influenced brewing techniques.
Key Questions
When was ground ivy first used in brewing?
Historical evidence suggests ground ivy was used in European brewing before the 14th century, prior to the widespread adoption of hops.
How did ground ivy compare to hops in brewing?
Ground ivy provided bitterness, antimicrobial, and antioxidant properties, but was less potent and effective than hops, which eventually became the dominant ingredient.
Why did hops replace ground ivy in brewing?
Hops offered a stronger, more consistent flavor and better preservation qualities, leading to their widespread adoption from the 14th century onward.
Was ground ivy used in other cultures’ brewing?
While primarily documented in European brewing, similar herbs were used in other regions, but ground ivy’s specific role is best confirmed in medieval Europe.
