The Medieval Garden Enclosed

The hot, dry weather that has us struggling to keep the gardens watered is all too welcome to the two-spotted mite, Tetranychus urticae, a worldwide pest of crop plants, ornamentals, and houseplants that is as much at home in greenhouses and apartments as it is outdoors. Two-spotted mites, along with other members of the Tetranychus family, are commonly known as spider mites. They are arachnids but are more closely related to ticks than to spiders.

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.

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.

Hop (Humulus lupulus) has been used as a vegetable (according to the Roman natural historian Pliny, the young shoots of the plant were eaten), as both fodder and bedding for cattle, as a dye, and, like its close relative hemp (Cannabis sativa), as a fiber plant. It also appears as a medicament in medieval and Renaissance herbals. The fifteenth-century Herbarius Latinus recommends hops for purifying the blood, opening obstructions of the spleen, easing fever, and curing both headache and jaundice. However, the most important economic use of hops in the Middle Ages and at the present writing is in brewing beer. Read more »
