Monastic brewing refers to the practice of brewing beer by monks in monasteries, a tradition that dates back to the Middle Ages. Monks often brewed beer for their own consumption, as well as for sale to support their monastic communities. This brewing was typically done using simple, natural ingredients, resulting in unique and flavorful beers. Many famous beer styles, such as Trappist and Abbey ales, originated from monastic brewing. Today, several active monasteries continue this tradition, producing high-quality beers that are often sought after by enthusiasts. The brewing process is often guided by the principles of self-sufficiency and community support.
