The very first mention of beer brewing at the Dětenice estate comes from 1307, during the rule of Beneš of Dětenice and Wallenstein.
The legend mentions a marauding knight Artur, who raided villages with his gang around Stará Boleslav and beat everyone who stood in his way, except for your virgins. He always stayed in a village until he ate up its supplies. The poor virgins had to be fully at his and his rabble’s disposal. The virtually became their slaves. At full moon shine, Artur always asked one of the virgins to brew beer according to his secret recipe. This was the magic beer of love. To keep the recipe secret, he had his man cut out the innocent virgin’s tongue. The magic beer was said to bestow superhuman sexual desire and increased the instinct to violence.
Knight Artur and his cruel companions reached the area of the Dětenice estate. It was the year 1307 when Artur wad defeated for the first time. He unsuccessfully crossed his sword with Beneš of Děteniceand Wallenstein, who cast the bleeding Artur after his defeat in the Dětenice dungeon. The whole Artur’s rotten gang was beaten to death.
Beneš of Dětenice was a powerful man. He knew very well about Arthur’s magic potion. This was also the only reason why the villain’s heart kept beating. Beneš longed to own the recipe for the magic beer of love and therefore he had Artur torture cruelly until the marauding knight gave the secret away. But this was not the end of Arthur’s punishment for all his. He was buried alive by the powerful lord of Dětenice.
A beautiful virgin daughter of Beneš brewed the beer at full moon in front of the Dětenice rampart according to the secret recipe and everyone who drank it felt strong sexual desire and therefore it was used from that time as a potion increasing potency.
The truth or a fairy tale? The answer may only be given by the walls of the old cellar or the chateau in Dětenice.
