It's true that Afonso Cruz has already brewed beer in the bathroom of an apartment he used to live in when he was in Lisbon. Don't worry, his methods have improved since then. He's honed his technique. His relationship with beer started nearly two decades ago and there's a mix of reasons behind it. On the one hand, there's his (natural) liking for the stuff. On the other hand, there was a literary influence. When he read a book written by a monk at some point between the Renaissance and the Age of Enlightenment, Afonso Cruz learned that beer and brewing can virtually amount to a school of thought that's pregnant with metaphors.
He's happier with the beer he produces in Alentejo today than ever before and he continues to study the allegorical aspect of the brew, which is why he has already included it in the title of one of his novels. It's all about the idea of transformation, essential in the narrative of Jesus Christ Drank Beer¸ through the concept of resurrection. It's somehow necessary for the cereal to die so that it may be reborn as a lasting beverage. More lasting than the cereal itself, or bread, for example, which is also pregnant with meaning.
