The Medieval Garden Enclosed

Hops (Humulus lupulus), considered today to be crucial to beer brewing, were not commonly used until the fifteenth century. Before that time, brewers added different herbs, such as??alecost??(Tanacetum balsamita), to their beer to improve its flavor. Several of these medieval brewing herbs can be found in Bonnefont garden.

Ale is made of malte and water; and they the which do put any other thynge to ale then is rehersed, except yest, barme, or godesgood, doth sofystical theyr ale.

???Andrew Borde, The fyrst boke of the introduction of knowledge, 1452

Beer was a staple drink for medieval Europeans, as it provided much-needed calories to the often undernourished population and was cleaner and safer to drink than water. Then, as now,??beer was made by brewing malted barley in boiling water to make sugars more available for yeasts to consume (see an image of Jorg Prewmaister tending his brew in a page from a fifteenth-century German manuscript, Amb. 317.2). This sugary, malty potion, known as “wort,” eventually becomes beer after the yeasts eat the sugars, releasing carbon dioxide and alcohol as byproducts of fermentation. On its own, wort is fairly flat in flavor, so brewers add additional ingredients, such as hops and spices, to enliven a beer’s taste.

Leather gauntlets are required when handling the stinging nettles grown in Bonnefont garden. The nettles grow in the middle of a raised bed, where visitors won’t brush against them inadvertently, and are caged with willow and labeled as an additional safeguard (see full image).

But this little patch which lies facing east
In the small open courtyard before my door
Was full ??? of nettles! All over
My small piece of land they grew, their barbs
Tipped with a spear of tingling poison.
What should I do? So thick were the ranks
That grew from the tangle of roots below,
They were like the green hurdles a stableman skillfully
Weaves of pliant osiers when the horses hooves
Rot in the standing puddles and go soft as fungus.
So I put it off no longer. I set to with my mattock
And dug up the sluggish ground. From their embraces
I tore those nettles though they grew and grew again.

???From Hortulus by Walahfrid Strabo. Translated from the Latin by Raef Payne. The Hunt Botanical Library, 1966.

The stinging nettles in Walahfrid’s monastery garden were clearly unwanted, but Urtica dioica is carefully cultivated in Bonnefont Cloister garden. A common perennial weed of moist soil and disturbed ground, stinging nettle is widely distributed throughout Europe, Asia, and North America, having crossed the ocean with the earliest English settlers. (See the U.S.D.A. database for more information). Nettles thrive on the phosphates that are a product of human habitation and animal husbandry, and are often found near long-abandoned settlements and waste dumps. Read more »
