Fact check: where did gruit occur?
Recently someone added me to a gruit chat group on Facebook, called ‘The Gruit Guild’. That meant many pictures of brews and of people picking herbs out on the heath. After all, gruit was a herb mix added to beer in the Middle Ages, before people started using hops. But recently, someone asked a historical question, so I was happy to interfere. The question was: where did gruit actually occur? A fact check!
